Everyone should know what to do if Android won't start. All the methods suggested 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 begins to work not quite correctly. Such an unfortunate incident is upsetting 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 an 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 the 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 her.
If your phone 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 your phone for a while.

Owners of one-piece 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.
A charging AC adapter may also be causing the problem. New charging device 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 are torn, 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 "freezes" with the screen turned off. It is worth figuring out what to do if the android does not start due to freezing.
All procedures will be aimed at maximum activation and restart of the device.
If your phone has a removable cover, take out the battery for a couple of minutes, then replace it and turn on the device. This 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 down 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 pretty much the same. If you can't find the reset button, open the instructions for the phone.

Photo: Reset button on a Sony smartphone There is another simple method that can "wake up" the phone. Connect it to your computer via USB. By detecting a new connected device or power source, the smartphone can 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).
There are several ways and options here too.
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 cloud.
Photo: Backup on the phone 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 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 is Android 2.2 or lower), and then "Reset settings". V latest versions go to "Settings", select "Restore and reset" or "Backup and reset", then click on "Reset", "Reset settings", "Reset tablet PC" or "General reset".

Photo: Restore and reset phone settings 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, home button and off). The Recovery technical menu should appear on the screen. You need to select the line wipe data / factory reset (down-up 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 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 the wipe cache partition.
Photo: Recovery Menu Important nuances of factory reset
There are some very simple but important rules to follow. For example, during all operations with a smartphone, it must always be connected to a charger. Then the phone will not turn off at the most important moment, ruining the entire setup process.
If you plan to do a factory reset in advance, you need to overclock your device's battery. To do this, first discharge it before turning it 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. You shouldn't worry, be calm and read every name of the menu very carefully. 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 a factory reset
Unfortunately, it is quite possible that the android will not turn on after a factory reset. You should again hold down the already familiar volume up, off and "Home" buttons and hold for 10 seconds. A menu will appear Recovery mode, select the item "wipe", confirm our decision by pressing the Home button.
In a collapsible phone, take out the battery, under it there is a factory reset button. After pressing it, the factory reset will be repeated and the phone will turn on.
If the advice did not help, be sure to contact the service center to flash the software.
conclusions
The listed tips are safe and effective enough. In most cases, they can be used to return the smartphone to normal and correct operation. You do not need to puzzle for a long time over what to do if the android does not start for one of the reasons. In the event that home diagnostics have not yielded a positive result, you need to contact a professional. The cause of the failure can be serious, such as completely faulty software, problems with the die, or other internal damage.

The glass on the phone (samsung a5) was replaced and the phone was reset, photos and videos were gone. Is it possible to recover and how? I tried it through your program - it didn't work.
Answer... Curious to know which recovery programs you used. The question also arises where you were looking for the deleted data - in the internal memory or on the sd card. As mentioned above, a factory reset erases the internal memory, so you need utilities like DiskDigger for Android. Another recovery method is by creating a snapshot of the internal memory and then searching for files on it ..

Answer... Really. Tenorshare Data Recovery runs only from a computer. It is not a fact that with its help you will be able to return data after a hard reset (that is, reset to factory settings). You need a way to recover from internal memory. See the answers above, where we answered a similar question.
I made a hard reset on the lg D724 phone, having previously synchronized everything. But I missed the most important thing - notes from the notepad application. The wife had a lot of important information in her notebook. Can you please tell me how you can restore this?
Answer... Try the EaseUS MobiSaver software. We have not tested, but the developers claim that MobiSaver can recover notes. However, it is important to note that after a hard reset, the internal memory is erased, and not all applications are able to work with it. So, frankly, there is very little chance of getting your text notes back after a reset.
I have samsung galaxy s7 edge. The problem is that when she entered the camera, she gave me such a notification "Camera error warning", after which every time I entered the camera, the phone gives this error. I reset the phone to factory settings, but it did not help ... clearing the cache in the camera settings and I dumped her data, but all my efforts were even, nothing helped.Went to the service center and said that they did not have the equipment to disassemble and see what was wrong with the phone, and in return they could send it to Moscow for repair, but it will take weeks or more. I don’t need it. Is it possible that if I roll the phone back to previous version OS, that is, on 6.0, since I have 7.0. Or just reflash your phone. Tell me if it helps? If not, then help and tell me a couple of ways to fix this error.
Answer... Go to Android Safe Mode and check if the camera is working. This will help determine if additional applications installed by you or along with the firmware affect the camera.
You may be using custom firmware - if so, we recommend finding alternative versions or flashing your phone to the official firmware.
If a factory reset really didn't help, you need to contact a Samsung service center or, as you mentioned, send it to Moscow for repair.
The phone has been reset to factory settings, how to recover data from the phone? I tried it through applications from Google Play, almost all of them require root. What is it and how do I get it?
Answer... Root access (or superuser rights) gives rescue programs access to the file Android system full control, including deleting and overwriting files. Although, in essence, recovery programs only need read-mode access.
Even if you find an application that does not require root, the chances of recovery are extremely small. Try installing the KingoRoot apps (installing root in a few steps) and DiskDigger for Android, it should work.
After resetting the Prestigio NK3 settings, the system writes that the sd card is not supported and suggests formatting. The reset was carried out with the card removed. There is a lot of necessary data, can you tell me if there is a solution?
Answer... Most likely, the hard reset did not in any way affect the safety of the data on the memory card. If you remove the memory card while other files are being written to it from the phone, the sd card file table may be damaged. You need to connect it to a computer or laptop through a card reader, check for reading errors with the standard Windows utility. If the errors are corrected, the sd card should open on the phone. If not, Recuva or DiskDigger with Dig Deep mode should find all files.
My wife made a hard reset on the Samsung Grand 2 Duo phone without making a backup. Photos and music are not so important, all phone contacts were lost and it was not possible to restore application data from Play Market... In all applications, everything had to start over. Please tell me, is it possible to restore it somehow?
Answer... The likelihood of recovering user data from applications depends on each application separately. So, if the user data was stored on the sd card, then you can restore the data. Otherwise, after a hard reset, you need to scan internal memory trying to find every separate file applications (the probability of doing this is rather small).
Phone contacts can be imported from a SIM card - of course, if you took care of backup contacts in advance. Check to see if the contacts are synced with your account Google and its associated Contacts service.
Even modern gadgets with high level advances in technology can fail. There are often cases when your smartphone simply does not want to turn on. Many people fall into a stupor, and do not even know what to do if the phone does not turn on. We will give the most common causes of this breakdown, as well as possible solutions.
What does not turn on and how to solve
In most cases, the problem is related to the battery of the gadget. A less common option is operating system problems. Before taking your device to a service center and preparing money for repairs, we recommend that you take several independent steps to identify the malfunction. The problem can be trivial, which you can solve without outside help.
Battery faults
There are several reasons why the phone won't turn on. Perhaps the battery has simply run out, and charging does not have any effect. This is the most common problem, but there may be several reasons for this:
- Another reason why "Android" does not turn on is the power button is broken. If you have new smartphone then it could be a marriage. Then carry it back and change it to a new one. Otherwise, you will have to go to the workshop, where you will have to replace the button for money, if the problem is really in it.
- The worst case scenario is that the power controller burned out on the phone. It is he who is responsible for the process of charging the gadget. The only way out is to take the phone to a service center and then replace it.
As you can see, users can solve most of the problems on their own if the phone does not turn on. To extend the life of the battery, do not often discharge the gadget to full zero, but use only certified chargers from the manufacturer.
Memory card
The problem may be that you inserted an SD card into the gadget that the smartphone does not support. This can lead to faults in the program code and inability to enable. How do I turn on the gadget? Just pop out the wrong memory card. If it still won't activate, you may need to reflash your smartphone.
Beforehand, always read in the specification which memory cards and up to what capacity your mobile device supports. You can also get advice from the sellers of mobile stores.
Incorrect system update
Some smartphones, after updating to a more recent firmware, turn into one that will no longer turn on in the usual way. The solution may be to roll back to the factory settings. You can do this with. To enter it, follow these steps:- Hold down the Volume Up key.
- Without releasing it, hold down the "Home" key.
- In parallel, press the third button "Power on".
On some smartphones, the transition is carried out by pressing "+ .- volume" and the "Power on" button. Using the volume keys, you need to move the slider to the line "Wipe data / factory reset", and then confirm your choice by clicking "Yes - delete all user data".
You will be able to clear the cash and data section. But be careful, as all personal data (photos, contacts, videos and apps) will be lost. If there is something important on your phone, contact a service center.
Relevant in the event that the download of the phone hangs on the icon with the "Android" image. This also indicates the incorrect operation of the firmware. On some devices, there is a special button for there, which can only be pressed with a needle or toothpick.
Viruses
If your phone won't boot, the files might operating system have been damaged by any virus. Here you will need to rewrite the phone. In some service centers specialists will be able to restore the phone's working capacity by cleaning it from viruses. To avoid such situations, we recommend downloading applications only from the official Play Market store, as well as installing an antivirus. You can choose ESET or Dr.Web for mobile devices.
What if my tablet stops turning on after a factory reset? In fact, there are several solutions to this problem. As usual, there are simpler and more complex ways to resolve this issue. Let's start, finally, with the most simple ones.
So, the most in a simple way it is a usual wait, because some tablets (especially low-power ones) can boot after a hard reset for about half an hour, you need to understand this. By the way, after flashing the situation is the same.
What else can you do? You waited, but there is no sense, then try to reset the settings again using Recovery, there you need to find the item "factory reset". It is likely that this will help get the tablet PC up and running.
Bootloop
If the tablet hangs on the power-on splash screen and, for example, a boot circle is spinning, or a robot with a ripped belly is shown, or a logo is simply displayed, then ONLY a flashing can be done. This condition is called a bootloop. After resetting the settings, this can happen due to the cryo-hands of the manufacturer's programmers. This is often found, for example, on smartphones from Ulefone.
It is extremely easy to solve the problem through a flashing using the SP Flashtool utility, if, of course, there is Mediatek (processor) on board, if Spreadtrum, then use the UpgradeDownload utility. By the way, there are various solutions for those devices that have Qualcomm Snapdragon under the hood. If you cannot cope with this on your own, then contact the RulSmart forum, in the first aid section. Experts will advise you for free.
