Modern man is a user of a powerful and productive touch phone. Calls, SMS, searching for information on the World Wide Web, navigation, photo and video shooting, games, reading books - in any of these cases it is necessary mobile gadget, which will instantly respond to the task.

However, it is worth considering that a modern smartphone is a complex, and often capricious technical device, which can fail at any time.

Before you rush headlong into a mobile device repair shop, you should figure out what caused the breakdown. After all, very often the user himself is able to revive his phone without resorting to the help of a specialist.

In our article, we will analyze in detail why the phone does not turn on, and we will also tell you how to restart your Android mobile device.

Dead battery

The most common reason, because of which the Android phone refuses to turn on - the battery has depleted to zero. A common reason why an Android phone won't turn on is a completely discharged battery. The solution here is simple - connect your smartphone to the charger. Please note that if the battery is empty, the phone may take a few minutes to start charging. In addition, the charger itself may not have enough power to fill the battery capacity.

Solution: Frog or Power-bank

If the design of the phone allows, you can remove the battery and install it in a special “frog” charger. A device with a non-removable battery is connected to a power bank.

A suddenly dead battery is a problem that even the owner of a recently purchased mobile device. In 9 cases out of 10, the problem here is related to improper charging of the gadget. If you want your mobile phone to last as long as possible, read our recommendations in the article How to charge your phone correctly

Faulty charger

What should you do if your phone doesn’t turn on even when it’s charging? Here the problem may lie in the charger itself, namely in its breakdown or damage.

Solution: Second charger

To check whether the charger is in working condition, connect the mobile phone to another charger. If charging has started, you can safely throw away the first charger - it is definitely broken.

Battery fault

On average, the battery in phones is designed to last 2.5 years. If your phone was purchased more than 3 years ago, the battery life may have expired.

Solution: Replace the battery

With a removable battery, everything is simple - go to the nearest mobile electronics store and buy a new battery. But with a non-removable battery you will have to go to service center.

Problems with charging contacts

Another common reason why the phone does not turn on is broken contacts, which means that even a working battery will not accumulate charge.

Solution: Diagnose and fix contacts

Check the contacts that connect to the battery - they may have moved a little. In this case, take thin tweezers and bend the contact antennae slightly. If you have a special screwdriver for electricians, its indicator will show whether there is voltage in the charger connector. Although in an amicable way, it is better to contact a professional technician with this problem.

Influence of external temperature

Winter and summer become a real test for any touch phone. The fact is that mobile devices do not tolerate high and low temperatures. For example, if you charge your smartphone to 100% and then ride with it on a hot and stuffy bus around the city, you will find that the battery has drained to almost zero.

Solution: Warm or cool the phone

Never charge an overheated or hypothermic phone. First you need to wait until the temperature of the mobile phone is balanced, and only then put it on charge.

Power button failure

A broken start key is also the reason why the phone stopped turning on. Between the button itself and the contact there is a thin rubber or silicone membrane. Due to constant pressure, it eventually wears out and bursts. This can also happen after the smartphone falls onto a hard surface.

Solution: Repair

Fault at the memory card level

The phone may refuse to turn on due to the SD card, especially if it was taken by hand or in an unreliable point of sale. In this case, there is a high probability that there is a virus on the card that prevents the phone from turning on. On the other hand, a functioning but overcrowded card can cause problems for the user.

Solution: Delete or format

It is better to throw away a defective card immediately, regardless of what is on it. And a card that is packed to capacity should be formatted.

Sometimes users download updates for the operating system from unreliable sources. Such actions can lead to the fact that the mobile device turns into a useless piece of metal.

Solution: Reset to factory settings

The most obvious way to deal with incorrect firmware is to roll back the phone to its original factory settings. You can do this in three ways:

1. Through the gadget menu;
2. Using service commands;
3. In the Recovery menu.

Method 1

1. Go to your phone settings
2. Click on the "Backup and Reset" section.
3. Select “Reset settings”.
4. Click on the button at the bottom of the screen.

After a few seconds, the system will roll back its settings and then reboot the smartphone.

Method 2

Service commands are a specific code that must be typed on the smartphone keyboard. Here are the three main combinations:

• *2767*3855#
• *#*#7378423#*#*
• *#*#7780#*#

Method 3

To enter Recovery Mode, follow these steps:

1. Turn off your phone.
2. Hold down the Power and Volume keys.
3. Select the wipe data/factory reset command from the list of options.
4. Click Yes.
5. Wait for the reset to complete and click Reboot System.

If you want to know thoroughly what is happening inside your mobile device, you can use special free applications. You can read about how to use such utilities in our article Smartphone diagnostics.

Excessive applet updates

Almost all applications installed on the phone, especially those whose work is connected to the Internet, constantly download and install large update packages. Such updates very often overload the phone.

Solution: Uninstall updates

A broken gadget screen is an obvious reason why the phone won’t turn on if there are no problems with the firmware and updates. As a rule, the display does not fail immediately. Pay attention to the moments that precede this:

• From time to time, stripes appear and disappear on the screen;
• The brightness sharply decreases and increases, within a few seconds the screen flickers and is restored again;
• The screen on the phone could suddenly show “strips” or start flickering during operation.

Solution: service repair

If you encounter such troubles, either the display itself is broken on the phone, or the causes of the problems lie in the cable that connects the screen to the board. Of course, you can try to carry out the repair yourself, but without certain technical knowledge, this can lead to complete breakdown of the phone.

Conclusion

Now you know what to do if your phone doesn't turn on. We will also give a few recommendations that will help extend the life of your gadget:

• Do not repair serious damage with your own hands
• Try not to drop your phone.
• Do not install applications from unverified and unreliable sources

If further Android logo does not load (pictures of the robot or screensavers from the manufacturer), then the cause may be hardware problems or system failures. The user can solve errors in the functioning of the system independently, and to cope with mechanical damage, you should contact a service center.

This article is suitable for phones and tablets of all Android device manufacturers: Samsung, LG, Sony, Huawei, Xiaomi, HTC, ZTE, Fly, Alcatel and others. We are not responsible for your actions.

If Android does not load on your tablet or phone when you turn it on, or the Android gadget starts but does not go beyond the logo splash screen, then there may be the following reasons:

• Lack of memory. The system may boot very slowly or may not start due to low memory. Removing unnecessary data and optimizing the application can solve the problem.
• Errors when flashing the device. This includes installing a damaged or unsuitable assembly, power failure, out-of-order firmware, and other factors.
• Incompatible with memory card. When the device turns on, but does not boot completely, you should try removing the memory card and trying to start the system again.
• Damage to the power button and its cable. This can “short-circuit” the phone, after which it will go into a cyclic reboot. Loading will be carried out up to the logo and in a circle further. Such errors occur periodically. They can be diagnosed at a service center.
• Hardware problems that occur after exposure to extreme temperatures, liquid, fall, or shock.
• Activation when the battery is very worn or discharged. Often models of Chinese companies and copies of brands suffer from this.
• Viruses and other harmful files. They can be downloaded from the Internet by accident or get onto the gadget via a flash drive when connected to a computer via a cable.

Before you try to troubleshoot your Android system, you need to understand why the system won't boot.

Restoring functionality

If your Android tablet or smartphone encounters errors when loading, this means that you should clear its memory and settings. Without this, the operating system will not be able to boot correctly.

Let's consider two ways to restore the functionality of the gadget. Method one:

• When the device is stuck on the screensaver, you need to hold down the power key and hold it for at least 10 seconds until the device turns off.
• When the screen turns off completely, you need to release the power button.
• Now hold down the volume rocker (volume up key). While holding it, press the power button.
• A menu should appear where we select the “Settings” item using the volume buttons and select it with the power button.
• Click on format the system (“Wipe data/factory reset”).
• Now select " Reset Android", then the Android device will reboot.

Increase

After this, problems with freezing on the logo and turning on should not occur. It should be remembered that such a reset will completely delete all data (except system data) from the device. There is no way to save them. Because of this, it is recommended to always copy important information, regularly synchronize your phone contacts with your computer, and back up the product.

The second method has the same result, but is done a little differently:

• We turn off the device as described in the previous option.
• We press both buttons loudly and wait.
• Release the buttons when the context menu appears.
• Select the item “Clean boot”.
• The settings will be reset and the gadget will reboot automatically.

Increase

If these methods do not solve the problem, then the product, in the best case, will require flashing, and in the worst case, repair of hardware problems.

Extracting data from a broken Android

If the error is solved without financial investment, by simply flashing it, then the user may have an important question - how exactly to save the information contained in the device’s memory. There will be no problems with the memory card: you just need to remove it from the gadget.

How then to extract information from the internal storage? For example, pull out the contacts.

Increase

If the system was backed up or at least turned on Google sync, then it will be quite easy to get the contacts. The user only needs to go to the Contacts app on Google's website to access full list synchronized contacts. If you need to transfer them to another gadget, then it will be enough to add a Google account to it.

Despite the prevalence of third-party resources with programs for Android, the main source of applications for this operating system remains the built-in Store Play Market. Providing convenient access to a centralized database of verified software, Play Market cannot, however, boast of 100% reliability and stability. There are many examples of the Android Store not working correctly. Thus, users often complain that applications from the Play Store are not installed or are not downloaded at all.

There may be plenty of reasons for this: settings failure, bugs in the Store itself, problems with the Internet connection, the presence of viruses, difficulties in unifying the platform for different processors, and much more. Due to the many potential causes, it can be difficult to determine the source of the problem; you often have to act at what is called the random method, trying one thing or another. Now let’s imagine that you have exactly this situation, and you cannot immediately determine why applications are not downloaded from the Play Market. In this case, you need to start your search with the simplest thing.

To eliminate the consequences of temporary failures and malfunctions, reboot your device. This may seem very obvious to some, but this is the method that often allows you to restore the normal operation of applications, including the Google Store.

Lost system settings

If rebooting does not help, step by step check that all system settings and Internet connection settings are correct. Firstly, make sure that the date and time are set correctly on your phone, secondly, you must be connected to your Google account, and thirdly, the Internet connection must be stable.

If the download does not start or after a while the message “Timeout has expired” appears, it is highly likely that the problem lies with the Internet connection. If Play Market does not download applications via the mobile Internet, check whether there are restrictions on mobile traffic. This can be done in the “Data Transfer” or “Traffic Control” sections.

Using modified versions of the Play Market

If possible, avoid using modified or hacked versions of the Play Market; they may often not work correctly. If you are using such a program, uninstall it and update it to the latest version.

Accumulation of conflicting temporary files

Another and very common cause of such problems with the Google store is the accumulation of temporary data in its folders and cache. Go to the application management section, find there Google Play, stop it and clean it by clicking the “Clear cache” and “Erase data” buttons. We do the same for the Google Play Services and Google Service Framework applications.

As an additional measure, it is recommended to go to the section Accounts - Synchronization and uncheck all the checkboxes there. After this, the smartphone must be rebooted, re-checked in the synchronization section and rebooted again.

Thanks to these simple manipulations, you can eliminate most of the problems that arise in the Play Market.

Bugs with Google Play updates

It is possible that the Play Market does not download applications due to the presence of some bugs in its update. Try rolling back to the previous version of the Store, to do this again, go to the application management section, find Google Play there and click the “Uninstall updates” button.

Additionally, you can try uninstalling updates to the Google Play Services and Google Service Framework applications.

Problems with Google Account

The Play Market is closely linked to the user's Google account, so it wouldn't hurt to rule out problems on this side as well. Try it first. To do this, go to settings, open the “Accounts” applet, highlight the Google entry, bring up the menu for it and select the “Delete account” option.

Reboot your device and log in again. Alternatively, you can create a new one Google account and log in using it. If the smartphone does not download applications from the Play Market even after that, the cause of the problem must be looked for on the device.

Low memory

Applications may not be downloaded or installed if there is little physical memory left on the device. Make sure your phone has enough free space, otherwise delete or move some of the data to the memory card. To remove temporary files, you can use a program like CCleaner or Clean Master. If the amount of space freed up with their help is small, move some of the applications to an external card. To do this, go to the application management section, switch to the “SD card” tab, tick the desired applications and click the “Move to SD card” button.

After transferring to the card, widgets of some programs may stop working. It is also undesirable to transfer system applications to external media.

Regional and age restrictions

Games and applications may also not be downloaded from the Play Market due to regional restrictions. In this case, the user usually receives the message “The application is not available in your country.” It is not difficult to bypass this blocking. There are two options. The first option involves using a VPN service, the second involves downloading the installation APK file of an application or game from a specialized resource www.apkmirror.com(APKMirror). You can also use the service apps.evozi.com, which allows you to “straighten” links to Google apps Play.

Unknown error code 24

A user may encounter this error when trying to reinstall an application that was previously uninstalled. The cause of the failure is the program files remaining in the system folders. The error is resolved as follows. Need to go to system folder /data/data/ and delete from it a directory or database file containing the name of the application being installed. Root rights are required to perform this operation.

Download queue

It is also worth noting another common malfunction in the Store - applications are not downloaded from the Play Market, and the Store writes “Waiting for downloading”. In general, this is normal if this moment the user downloads and installs several applications. Also, a message may appear when, for some reason, the application is temporarily unavailable in Play Store. It's a different matter when the message doesn't disappear long time, which usually indicates a boot order error. In most cases, the problem can be resolved by simply clearing the download queue. Launch the Play Market, go to the “My applications and games” section, find stuck downloads there and delete them. If the error continues, clear the cache and temporary data Play Store, having previously stopped the operation of the Store.

Many of the errors have a code that can be used to determine the cause of the problem and take appropriate action. For example, an error code 403 most often indicates a conflict between two accounts on one device, errors 194, 492, 413, 495, 498, 504 – for the presence of “extra” files in the cache and Play Market directories, as well as the Google Play Services and Google Service Framework programs. These errors can be resolved by clearing the cache and application data. But fixing error code 491 needs to start by deleting your Google account.

And finally, a radical method is to reset the device to factory settings. Like flashing, this is an extreme option and it makes sense to resort to it only when other methods have not brought the desired result.

Hi all. Today I would like to look at all the most common reasons why an Android smartphone may not turn on. I will not touch on situations where disassembling the phone and interfering with the electronics is required, since this is the work of completely different specialists.

If your smartphone or tablet suddenly stops turning on, you don’t have to immediately run to a service center or workshop and have it repaired. Most likely, there is a chance that you can do it on your own and save some money (programs for home accounting on Android will also help you save money, look for them on the blog). Below we will look at the main measures that can be taken if your Android smartphone or tablet does not turn on. So, let's get started.

Android phone won't turn on. 5 ways to solve the problem.

Method No. 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 problem turns out to be a dead battery. And I understand perfectly well when they tell me that they’ve been charging their smartphone all day, but it still won’t turn on. Some devices have one unpleasant feature - if you discharge the battery too much, it will not charge, even if you keep 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. Then you 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 cell 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 exposed wires to the battery with tape for a few minutes.

Important. Do not reverse the polarity.

Method No. 2

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

Method No. 3

If the phone does not turn on, then perhaps it is simply frozen. To revive your device, we’ll use a long-known but still relevant method - remove the battery and reinsert it.

Unfortunately, this technique does not work on many modern phones with non-removable batteries. 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, as a rule, it is located near the SIM card slot or on the back of the smartphone or tablet. Near the reset button there is sometimes a message reset or off. The photo below is an example of the location of such a button in a smartphone.

Method No. 4

This method is applicable if your phone not only does not turn on, but does not turn on completely. For example, it gets stuck on your Android logo and nothing else happens. This happens due to a glitch in the smartphone software. Then a hard reset or, translated, a hard reset, will help us. It is done differently for each device model. 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 this topic on the blog.

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, search the Internet.

For example, this function is not available by default in many Sony phones, but the manufacturer has provided the ability to restore the software using special utility Sony pc companion.

Method No. 5

Not often, but it still happens that smartphone won't 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 to avoid fanaticism, otherwise you will only make things worse.

Recently I encountered a problem that I urgently needed to update the application, but the available WI-FI networks there was no one nearby. I decided to update using the mobile network, unchecked the box in the market, but the download still did not start, instead the play market wrote “Waiting for WI-FI network” and the process stopped. There is of course no option in the Play Store settings related to the cause of this problem.

Why Xiaomi refuses to download applications and games using the mobile network

In fact, everything turned out to be very simple and clear, and the play market turned out to be not to blame for the current problem. IN operating system My Xiaomi - MIUI has such a feature as a built-in bootloader. He is responsible for downloads, updates, their speed, size - well, in general, for everything related to downloading data to a smartphone. In this case, all applications automatically pick up its settings. For example, if the downloader only downloads via WI-FI, then no matter how much you want, you won’t be able to download anything without it. This is exactly what happened, the Play Market simply could not update the application, since the file size when downloading was larger than the maximum allowed in the bootloader settings.

To be able to download and update applications not only via WI-FI, but also via a mobile network, follow the instructions below.

Instructions for setting up the Xiaomi bootloader (MIUI)

First, go to “Tools” - Tools on the smartphone’s desktop. Here we select the “Downloads” icon - Downloads.

A window opens in front of us where we can view downloaded applications, games, pictures and everything like that. We are interested in settings, so we click on the button with three dots in the upper right corner.

Menu items pop up, one of which is called “Settings”. This is exactly what we need, so we click on it.

Now we are looking for the phrase “Download size limit” - restriction mobile internet. By default there is usually 1MB. We are not happy with this because we want to install applications with large size. Let's tap on this point.

We select from the required options the one that suits us and click “Ok”.
That's all, now you can safely download and update applications using the mobile Internet.

Note: if you do not have unlimited Internet on a smartphone or you use up your allocated traffic very quickly, then it’s best to choose small sizes for downloaded files, as this may put a dent in your wallet.
