The lenovo smartphone turns on before the splash screen. Android smartphone stuck - what to do and how to restart? Phone charges but won't turn on

Many people have at least once experienced a freezing mobile phone. There are various reasons why a smartphone freezes. special attention. Usually phones freeze and stop responding due to mechanical damage or failure. software.

One-piece cases made of polycarbonate or aluminum, special protective glasses can only mask the problem. However, often people are faced not with mechanical damage to phones, but with software failures. Regardless of the cause of the problem, you need to know what to do if mobile phone freezes and does not respond to any buttons.

Often, iPhone mobile phones freeze after a software update or in special games. Sometimes it is enough to put the mobile phone down for 5 minutes so that it performs the necessary processes and starts responding again or ends the application. However, sometimes this is not enough. So there are different ways get your iPhone working.

You can try to close the application yourself. To do this, double-click on the Home button and “swipe” up all unnecessary running programs. This method is effective if the phone slows down due to minimal memory or low battery.

Sometimes you need to press the power button and hold until a window appears asking you to turn off your mobile phone. At this time, you need to release the power button and press Home to end the problematic application. If desired, you can swipe the button on the screen from left to right and turn off the smartphone. Then the phone turns on and it will be working.

In some cases, phones freeze on boot when the manufacturer's logo is displayed. This usually shows up during a software update. Even after turning it off and on, the problem persists. In this case, you need to use iTunes. The switched off phone is connected to the computer, after which you need to hold down the power and Home buttons for 12 seconds.

After 12 seconds, you can release the power button, but Home should be held until the phone is detected in the program. Then you need to select "Restore" and restore all existing data from the backup. After that, the phone will be working again.

The power button may be damaged. In these problematic situations, the Assistive Touch function will help, which allows you to refuse to use physical keys. The function is activated in the settings: "Universal access" - "Physiology and motor skills". However, the phone will turn on only after it is connected to a personal computer with a special cable.

Sony mobile phones are often offered with non-removable batteries, but the Japanese manufacturer has added a dedicated hard reset button. The button is located under the cover of the SIM card slot. For this reason, you need to remove the plug. Then, with a thin, non-sharp object, press the button and hold it. The button is released only after the phone vibrates.

Sometimes this does not give the desired result. In such situations, you need to press the OFF button under the plug and hold for 2 minutes, despite the vibrations.

Then the phone is connected to the charger and charged until the charging indicator appears. Only then can you turn on the phone.

Samsung can be equipped with a removable or non-removable battery. Usually the standard instruction helps.

1. It is required to simultaneously press three buttons at once: Volume down, Power, Home.
2. Three buttons are held until the screen of the mobile phone goes blank.
3. The device should reboot.

This instruction is standard. It will fit any phone. In this case, if the mobile is equipped with a removable battery, you can remove the battery and then insert it back.

Xiaomi mobile phones can be rebooted in soft or hard mode.

This reboot option is required for updates or full phone memory. The reboot command is generated by the operating system, so in most cases the data is saved.

1. Initially, you need to press the power button (on - off).
2. Then you need to wait for the menu window.
3. Now you can click on the "Restart" item. The device will reboot.
4. This option will be relevant if the phone responds to mechanical buttons and does not respond to touch.

In this case, they also press the power button, but usually hold it for up to 20 seconds. The button is released only after the Mi Logo appears on the screen. If nothing happened, you can press the button for up to 25-30 seconds. This hard reset helps in many situations.

If neither soft nor hard reset is successful, you will need to use special computer programs or contact a service center.

The Lenovo smartphone can also sometimes freeze. This is usually due to operational failures, full memory. For this reason, it is recommended to regularly monitor the memory and make timely backups, transfer valuable files.

It should be noted that it may often be necessary to perform a Lenovo factory reset. Often, special programs and utilities are used for this.

In most cases, rebooting a frozen phone can be done by the user of the technology. Only in difficult situations will it be necessary to contact the service center to determine the cause of the problem and its further elimination.

Everyone should know what to do if Android won't start. All the methods proposed below do not require additional technical knowledge and cannot harm the operating system or the device itself.

The Android operating system is not only the most popular in the world, but also very simple, convenient and reliable. Nevertheless, any modern device sooner or later fails or starts to work not quite correctly. Such an unfortunate incident upsets and can spoil the nerves in order. There are times when the problem is serious and only a specialist can help. But before you go to the service center, you should try a few simple tricks that can completely revive your smartphone.

Battery or charger

It may sound trite, but more than half of the problems with turning on the android are related to the battery or charger. This is not about the fact that you just forgot to charge your phone, but about more global reasons.

With a long and active use of a smartphone, its battery gradually wears out. There comes a moment when it is discharged to such an extent that an ordinary network adapter can no longer help it.

If the phone model is old and collapsible, remove the battery and use the frog tool. This is a charger that provides a more powerful charge and can save the phone for a while.

Owners of solid and non-separable models at home should not experiment. If you suspect that the battery may have failed, contact a service center to have it replaced.

The charging AC adapter can also be the cause of the problem. New chargers may not be original or compatible with this smartphone. This means that the battery does not receive energy during charging, and the android simply cannot start. In old chargers, contacts come off, wires break, etc. Therefore, it makes sense to try to charge the phone from another adapter.

Hardware problems (phone freezes)

It may happen that the phone is not turned off at all, but “frozen” with the screen turned off. It is worth figuring out what to do if the android does not start due to a freeze.

All procedures will be aimed at maximum activation and restart of the device.

If the phone has a removable cover, remove the battery for a couple of minutes, then put it back in place and turn on the device. Such a simple manipulation often gives good results and returns the smartphone to normal operation.

With more modern models, the situation is a little different, but there is nothing complicated here either.

If, after a standard single press of the power off or lock button, the phone does not turn on, hold this button for 10-15 seconds. After that, the screen may light up and the phone will continue to work.

The second way to reboot will be the so-called "forced reboot". To do this, you need to find the reset button and gently clamp it with a needle, paper clip or toothpick. In all models, it is located in different places, but looks almost the same. If you can't find the reset button in any way, open the instructions for the phone.

There is another simple method that can "stir up" the phone. Connect it to your computer via USB. Upon detecting a new connected device or power source, the smartphone may wake up from its sleep mode.

Software malfunctions

If none of the above methods helped, the last chance to turn on the phone yourself will be full reset settings (in technical circles it is called).

Here, too, there are several ways and options.

To begin with, consider the situation when the phone still turns on, but it does not work correctly and the android constantly hangs.

When you return to the factory settings, absolutely all information will be deleted and the phone will become just like new. Therefore, if possible, it is imperative to back up all data. New models in their menu already have such a function as “data backup”, “backups”, and then full data recovery. Information can be copied to any existing account, Google drive or to the cloud.

It is also possible to copy all data to a PC or laptop using a USB cable or, for example, a program Share it (Download). It is worth remembering that contacts from the phone book will be saved in one of the folders as a .vcf file.

To reset the settings, go to "Settings", select "Privacy" (if the version of Android is 2.2 or lower), and then "Reset settings". In the latest versions, go to "Settings", select "Backup and reset" or "Backup and reset", then click on "Reset", "Reset settings", "Reset tablet PC" or "Master reset".

When the phone is turned off and it is not possible to turn it on, you must simultaneously hold down the volume up button and the off button (on some models, the volume button, the Home button and the off button). The recovery menu should appear on the screen. You need to select the line wipe data / factory reset (up and down control is carried out using the volume key). Then click on Yes, delete all user data.

Do not forget that for a full rollback to the factory settings, you need to clear the entire cache and SD card. To do this, you can go to "settings", "memory", "clear SD" or clear immediately upon reset by clicking on wipe cache partition.

Important nuances of resetting settings

There are some very simple but important rules that must be followed. For example, during all operations with a smartphone, it must always be connected to charging. Then the phone will not turn off at the most important moment, ruining the entire settings process.

If you plan to reset the settings to factory settings in advance, you need to “overclock” the battery of the device. To do this, first discharge it until it turns off, and then fully charge it. This will ensure that the battery.sys file works properly.

Since all phones are very different in interface and Android firmware, some users experience certain difficulties during the procedure. Do not worry, be calm and carefully read each menu name. If the smartphone model is very new or rare, it is better to study the instructions for it or go to the official website.

Problems after factory reset

Unfortunately, it is quite possible that after resetting the settings, the android will not turn on. You should again hold down the already familiar volume up, turn off and "Home" buttons and hold for 10 seconds. The Recovery mode menu will appear, select the "wipe" item, confirm your decision by pressing the Home button.

In the collapsible phone, remove the battery, under it is the factory reset button. After pressing it, the reset will repeat and the phone will turn on.

If the tips did not help, be sure to contact the service center to flash the software.

conclusions

The above tips are safe and quite effective. In most cases, they can be used to return the smartphone to normal and correct operation. You do not need to puzzle over what to do if the android does not start for one of the reasons. In the event that home diagnostics did not give a positive result, you need to contact professionals. The cause of the failure can be serious, such as completely faulty software, problems with the matrix, or other internal damage.

Dear readers! If you have any questions or comments on the topic of the article, please leave them below.

Hi all. Today I would like to analyze all the most common reasons why an Android smartphone may not turn on. I will not touch on those situations when you need to disassemble the phone and interfere with the electronic stuffing, since this is the work of completely different specialists.

If your smartphone or tablet suddenly stops turning on, it is not necessary to immediately run to a service center or workshop and send it in for repair. Most likely, there is a chance that you can manage on your own and save some money (home accounting programs for Android will also help you save, look for them on the blog). Below we will consider the main measures that can be taken if an Android smartphone or tablet does not turn on. And so, let's get started.

Android phone does not turn on. 5 ways to solve the problem.

Method number 1

From my own experience I will say that in 80% of all cases, if they come to me with a problem that the phone does not turn on, the whole thing turns out to be a dead battery. And I perfectly understand when they tell me that they charged the smartphone all day, but it still does not turn on. Some devices have one unpleasant feature - if the battery is very much discharged, it will not charge, even if you support it on charge all day.

In this case, a frog-type charger will help us, which allows you to charge almost any battery directly by removing it from the phone. It is enough to recharge the battery in this way for 15 minutes. After that, insert it back and put the phone on charge as usual, everything should be OK.

If getting a frog is problematic for you, then you can use any old mobile phone charger. Cut off the old plug and protect the wires.

Make sure that the charger is not connected to the outlet at this time.

We fix the bare wires on the battery with adhesive tape for a few minutes.

Important. Do not reverse polarity.

Method number 2

Faulty charger. Of course, the second thing to check is the serviceability charger. Everything is simple here - we take a known working charge and try to charge our smartphone. If the process has begun, then we buy a new one and rejoice. Although it sounds trite, it helps every fifth person.

Method number 3

If the phone does not turn on, then it may just be frozen. To revive your device, we use a long-known, but still relevant method - take out the battery and insert it again.

Unfortunately, this technique does not work on many modern phones with a non-removable battery. In this case, to reboot, you need to find the reset button and press it, for example, with a paper clip. It can be anywhere, but is usually located near the SIM card slot or on the back of a smartphone or tablet. Near the reset button, sometimes there is an inscription reset or off. The photo below is an example of the location of such a button in a smartphone.

Method number 4

This method is applicable if your phone does not turn on, but does not turn on completely. For example, it hangs on your Android logo and nothing else happens. This happens due to a malfunction in the software of the smartphone. Then a hard reset or, in translation, a hard reset will help us. It is done differently for each device model. In order to find out how, enter the name of your phone and the words hard reset, for example LG G3 hard reset, in Google or Yandex and follow the instructions. In the future, I hope to create a separate section on the blog on this topic.

Unfortunately, not all smartphones support hard reset, it depends on the recovery installed in the device. If you are interested in learning more about what it is, look on the Internet.

For example, there is no such function by default in many Sony phones, but the manufacturer has provided the ability to restore the software using a special Sony pc companion utility.

Method number 5

Not often, but it does happen smartphone does not turn on due to the fact that the contacts under the battery do not reach. To fix this, you need to use tweezers or a small screwdriver to bend the contacts to improve the connection to the battery. The main thing here is without fanaticism, otherwise you will only make it worse.

If none of the methods helped and your phone still does not turn on, then the problem most likely lies in the hardware itself and only a service center can help you.

If your mobile smartphone, tablet on the Android operating system has stopped turning on, loading or charging, a failure has occurred, which we will try to fix. A smart phone, like a computer, can freeze from time to time without loading the system, or not turn on at all. Unlike the PC, the problems here are not so serious, but they require solutions. On an unstable load operating system, failures when turning on or during operation, it is necessary to clear the internal or flash memory of the device, as well as reset the settings. These actions will allow the platform to recover and earn steadily.

To format the memory, go to "Settings".

Next, go to the "Memory" section.

Select the category you want to format. Be careful, because after formatting all user data will be lost!

And the first thing we will do to solve the common problem of freezing when turning on a mobile gadget is to delete all user settings, returning the platform to factory settings. Hold the power button for 12 seconds to turn off the tablet / smartphone. When the screen goes completely blank, turn the device back on. To turn on, use two buttons - first the volume (increase), and then the power.

The context menu will appear. To select a specific item, use the volume buttons. We need Settings or Settings if your gadget's language is English. Using the power button of the smartphone / tablet, click on this item.

We need to format the system, so we select this item in the Settings. Before you take this step, remember that all user settings along with the content will be permanently deleted. This is if you do not save backups in "cloud" storages. By the way, this is a reason to think, because mobile device can be disconnected at any time and “emergency” methods will be needed to restore the operation of the platform.

If you're using a microSD, take it out. If you need to format it, you will have to do it separately. After the end of the programming process, click Reset Android to restart your smartphone or tablet.

If the problem persists and the device continues to hang when loading the OS, use another option. Only in this case, we will reset the settings, which means we will lose all user data. Follow 4 steps:

Be careful, as this method will return the phone to the state laid down by the manufacturer!

Here are two ways to solve the inclusion problem!

The more complex the technique, the more it tends to behave unpredictably. Before the era of smart devices, everything was simpler: if the mobile freezes, you can simply turn it off and on, in extreme cases, take out the battery and put it back in.

But with modern devices, such a number does not work, and they freeze, unlike more often. Let's try to deal with the most frequent cases of "strike" and decide how to deal with them.

Two main reasons for phone freezes

The main reasons for the freezing of the phone include:

1. mechanical damage;
2. software failure.

Let's analyze in detail.

Mechanical damage

Surely many readers decided to skip the section with such a heading: they say, if my phone was damaged, it would be immediately visible. And my neighbor has a half-screen in the mesh, and everything works. And in vain!

The era of the good old Nokia 3310 and other unkillable "bricks" has passed. The gadgets of the second decade of the 21st century are incomparably more fragile. There may not be any signs of impact or pressure on the case, but for electronics, shocks could be a serious test.

One loose contact can cause malfunctions.

So solid aluminum cases, molded polycarbonate, Gorilla Glass or other protective glasses may not prevent, but, on the contrary, mask the problem.

Software failure

Fortunately, more often than not, problems now occur due to software failures. We say "fortunately" because software "diseases" are easier to cure. No need to climb into the electronic stuffing with a screwdriver and a soldering iron.

For the most part, software problems are solved by uninstalling specific applications that are causing RAM or CPU overhead. Sometimes the programs themselves do not even need to be deleted, it is enough to unload them from memory using the task manager.

What to do in these two cases

The easiest way to deal with a freeze is if the case has obvious signs of damage. In this case, look for the nearest workshop that repairs gadgets and return the device for repair. Often, after this procedure, all data from the system is erased, and you will have to restore all its contents.

We remind you of the importance of a timely, or better, permanent backup!

What to do if the phone freezes, outwardly intact? If there are no obvious damages on the case, but you do not like the behavior of the system, we will proceed from the fact that the reason is in the software. And only after trying all the troubleshooting software tools, we remember that there are workshops in the world.

Causes of phone freezing on Android

The main reason for any computer freezing (and an Android device is actually a computer) comes down to a lack of hardware resource. To process all tasks relevant to this moment, may not have enough memory, processing power of the processor.

Video: stuck when turned on

Little RAM

As you know, RAM does not happen much. Although by 2015 it is in the order of things to equip even affordable models with two or three gigabytes of RAM, they are often not enough. The fact is that Android is in no hurry to automatically unload already closed programs. The system reasonably believes that when restarted, it will be easier to open an application already hanging in RAM.

But if there is a lot of such “background” software and it is gluttonous, the system may feel an acute shortage of RAM.

Then the touch screen may not respond, games or programs take a long time to start or switch - in general, the phone freezes. What do we advise you to do?

• remove programs that you can do without;
• disable background work and push notifications for programs from which notifications are not needed;
• install the task manager and set up regular memory cleaning, if necessary, set exceptions;
• clear the cache (through the same task manager);
• remove all widgets from the desktop, except for the most necessary ones

To be honest, we can’t wait until the smartphone can simply increase the memory by adding an extra module. Google, where is your Project ARA?

High CPU load

The “appetites” of various applications are seriously different. Some of them quite seriously load the processor. Even multi-core designs specifically designed for high peak loads can't keep up with today's games, which come at a price for spectacular graphics.

Fans of intensive communication cache large volumes of photos, correspondence, contact databases. Programs like graphic editors also force the processor to work at full capacity. The most interesting thing is that even after the release, such programs continue to hang in memory and load the processor.

It is easy to distinguish memory problems from problems with the processor: in the latter case, the smartphone heats up very noticeably. Different chipsets differ in this regard, but the heat is always felt.

Program crashes

Alas, not all Android applications are well optimized. Some of them can cause serious malfunctions.

What should be done?

• remove all questionable applications;
• do not install APK files from third-party sources (this is for the future);
• if the failures are repeated, and you still cannot establish the reason - make a hard reset.

What to do if your Android phone freezes

How to deal with the causes of freezes - we roughly figured it out. But all this somehow later. But what if your smartphone freezes right here and now? We have prepared recommendations for getting the electronic sufferer out of stress.

Shutting down applications

Remember, just above we talked about task managers? In addition to third-party solutions, like ES Task Manager, Android also has a built-in one.

You can use it like this:

Even closing one or two unnecessary "workers" can have a positive effect.

Unnecessary applications can also be closed "in bulk" using third-party dispatchers.

Restart Android

As a rule, in all Android devices there is an option to soft reboot directly from the OS.

For this you need:

It is not at all a fact that a hanging smartphone will reboot quickly. If a process slows down the work, then it can be difficult to “kill” it. But when the reboot takes place, Android will start to work better.

Use this to uninstall recently installed updates and new programs. Perhaps one of them is the root of the problem.

Force reboot the device

Is it always possible to turn off the phone if it freezes? Often it does not respond to any gestures on the display, nor to pressing the touch buttons. How to turn it off if there is no reaction to standard actions?

However, there are “soft reboot” methods that are designed specifically for such cases. Usually, for a soft reset (this is the name of this procedure), you need to hold down the power and volume down buttons at the same time. These buttons are chosen because they are present on all Android smartphones. However, there are exceptions, so check the details in the instructions for your particular device.

Reset

In especially severe cases, only the most radical solution helps - resetting all settings. This most effective tool does not even require you to specify why your mobile phone freezes.

Please note: this procedure destroys all data on the smartphone, returning it to its original factory state. Therefore, make sure that all your contacts, mail, SMS history and important files are saved in archives or on cloud services. In most cases, sync is enabled by default.

The reset can be done directly from the menu. For example, in Android 5, you can find the desired item like this:

Different manufacturers may have different menu items, but the principle is the same everywhere:

• go to Settings;
• select the "General" section;
• select "Backup and Reset";
• select "Reset settings";
• confirm reset.

If you understood general principle, then you can easily find the desired item on smartphones with other OS versions. By the way, you can enable backup in the same section of the menu.

Hard reset

The words "hard reset" sound like sandpaper. And indeed, this procedure will polish the state of your gadget to a shine. As a rule, for a hard reset of an Android smartphone, you need to simultaneously hold down three keys: power and volume up. These buttons put the smartphone into recovery mode.

The touch screen does not work in this mode.

Therefore, you need to manage your smartphone as follows:

After that, your phone will take a long time to reboot, and after restarting Android will be as good as new. We hope you have enabled synchronization? Then your phone book and other data is stored on Google servers and will be returned to you soon.

With code

In some cases, to fully restore the smartphone, you need to work with the engineering menu. Launch the phone application and enter the code in it (it looks like a USSD request, but has a more complex structure). For example, for the LGGT540 model, the code looks like this: 3845#*540#.

After entering it, you will see a menu in which you need to select the Factory Reset item. For other models and OS versions, the code will be different. The information you need is easy to find on the Internet.

So, hanging is not a reason to despair. In most cases, you can "cure" it yourself.

However, remember the following rules:

• if you have precise instructions, follow them. Smart people have already developed ways to escape, you just have to not get confused in them. If not, you can ask for advice on thematic forums;
• follow the advice that applies exclusively to your model and version of Android. Even if the names are similar, important details may differ;
• some recovery processes take a long time, sometimes for hours. Do not panic;
• for the future: you should not buy the cheapest Android smartphones, you will then have to pay extra for them with nerves. It is better to overpay a certain amount and take a device with a power reserve that does not hurt.

Remember: freezes are treated. And almost everything you need for this is in your hands.
