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 her.
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 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 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.

Software malfunctions
If none of the above methods helped, the last chance to turn on the phone on your own will be a complete reset (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 a full data recovery. Information can be copied to any existing account, Google drive or to the cloud.

To reset the settings, go to "Settings", select "Privacy" (if the version of Android is 2.2 or lower), and then "Reset settings". AT 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".

The recovery 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 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.

There are some very simple but important rules to follow. 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 provide correct work battery.sys file.
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.
findings
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.

What else can be done? You waited, but it’s no use, then try resetting the settings again using Recovery, you need to find the “factory reset” item there. It is likely that this will help start the Tablet PC.
Bootloop
If the tablet freezes on the power-up splash screen and, for example, the loading circle is spinning, or a robot with a ripped open stomach is shown, or a logo is simply displayed, then in this case ONLY a flashing can be done. This state is called a bootloop. After resetting the settings, this may happen due to the cryo-handedness of the manufacturer's programmers. This is often found, for example, on smartphones from Ulefone.
It is extremely easy to solve the problem through flashing using the SP Flashtool utility, if, of course, on board Mediatek (processor), if Spreadtrum, then use the UpgradeDownload utility.

AT modern world You can't imagine a person's life without a phone. Every person has this little helper. It makes it easy to contact the desired subscriber. But imagine that your Android phone does not turn on. What to do in this case? Of course, without a smartphone it will be quite difficult. If you do not have a spare gadget, then you need to quickly fix your device. In this article, we will look at why the Android phone does not turn on.
Mobile check
If the phone has stopped turning on, then you should not immediately disassemble it and see what could happen there. Of course, if you do not have certain knowledge, all these actions can be disastrous for a smartphone. Subsequently, repairs can only become more complex and costly. Why won't my Android phone turn on? What to do in this case?
Before proceeding with cardinal actions, it is necessary to check - maybe it did not break at all. First you should find out if the battery is charged, or maybe the reason is software failure device.
Mobile device battery check
As we have already found out, the phone may not turn on due to low charge battery. We put the smartphone on charge and wait about 30 minutes. After that, we try to turn it on. If the phone was able to "revive", then the problem is high consumption charge. How can this be fixed? It is enough to turn off Bluetooth and Wi-Fi after use. These elements are constantly working to find a possible network in order to inform the user about it. If you turn off these elements, you can save a charge for a longer period. You should also reduce the brightness on your smartphone, as a bright screen consumes a lot of energy.
If you have a function on your mobile phone that allows you to change the brightness automatically based on the light in the room, then you should turn it on. Let's get back to the problem. If the phone was able to turn on when it is charging, then let it stand for about 4 hours. It is worth checking the expiration date of the battery - it may be time to change this component. If the phone does not turn on, but the Android is charging, you need to consider other possible situations.
Smartphone power button
The phone may flash but not turn on. This may be due to a malfunction of the power button. The reasons why it may not work may be different:
- If you have just purchased mobile phone, and it does not turn on, the power button may be faulty, and the reason lies in the factory marriage. What to do in this case? You need to contact the store where you purchased the smartphone and ask for a refund, replacement or repair of the phone. The seller must do something in this case.
- Another reason is also possible, which is already associated with your carelessness. If you spill liquid on mobile device or dropped it, then there may be various reasons due to which the phone will not turn on. In this case, do not disassemble the device yourself. Of course, if you have a warranty, you can try contacting a service center. Otherwise, you will also have to resort to the help of a professional. Unfortunately, even he is not able to fix any phone.
Memory card
So, your Android phone does not turn on. What to do? The reason may lie in the SD card. Your phone may not support a particular memory card, causing the mobile device to freeze or not turn on at all. You should choose a memory card in specialized stores, having previously learned that it will fit your smartphone. If different memory cards cause the same effect, then the problem is in the phone. In this case, you need to reflash the mobile device. You can do it yourself, but you should be careful, as you can only do harm.
Phone won't turn on after Android update
Sometimes situations happen with smartphones when it does not turn on after the update. As a rule, new gadgets are more prone to this. Various updates come to the mobile device, which, unfortunately, are not safe. Usually smartphones that have constant access to the Internet are affected by this. After such updates, the phone may randomly turn off and turn on after a while.
Another situation is also possible: you are trying to turn on your phone, and Android lights up there and nothing else happens. Reboots bring the phone back to this problem again. So, your Android phone does not turn on again. What to do? In this case, it is worth trying to turn off the device and stick out the battery for a few minutes, then turn it on and reset the settings. If the problem was not serious, then you will succeed, and after a while the phone will return to its previous state.
If it refuses to work adequately, then you should use a hardware reset. This will clear your phone of updates and all information. But, most likely, it will return to working condition. Of course, all personal information will disappear from you, but returning the phone to its former life will probably be more important. This reset will be done differently for each smartphone. You need to find suitable way for your model. Phone won't turn on after factory reset? "Android", unfortunately, may not be suitable for such a solution. In this case, you will need to reflash your device.
After flashing the phone does not turn on (Android)
If you unsuccessfully flashed your device, then it may not turn on or hang on the Android logo. What to do in this case? Of course, you will have to reflash again.
First, go to the manufacturer's website and look for required firmware, which will fit your model. You should not look for firmware through a search engine, as it will give out a lot various programs which most likely won't work. So you can only aggravate the problem and bring your smartphone to a “brick” state.
After the firmware, the phone does not turn on. "Android" can still be brought back to life. You will need to properly install new firmware. If you do not know how to do this, then you need to contact the service center. So you can be sure that everything will be fine with the phone.
Mechanical damage
The most common cause of smartphone failure is mechanical damage. If the phone has been dropped or you have spilled liquid on it, then this is already a serious problem that cannot be dealt with so easily.
If the fall was not serious, then you can try to stick out the battery, SIM card, SD card. After a while, we return everything to its place. If the phone worked, then you were lucky, and his contacts just went away. Otherwise, the problem is more serious. If you do not have the necessary knowledge, then you should not try to disassemble and repair the mobile device yourself. In this case, contact the service center.
Users of modern devices have become accustomed to the useful function of rolling back the phone to factory settings. This helps to resolve most software problems or correct adjustments made to the machine's settings. It rarely happens that after a factory reset, the phone does not turn on. Why this could happen and how to solve the problem, we will learn further.
We already know that a hard reset does not always help return the phone to its original state, but, on the contrary, worsens an already distressed situation. After an unsuccessful rollback, you can observe that the android does not start, a dark screen remains, or a cyclic reboot occurs. That is, the device is able to show signs of life, but is not able to boot the OS.
In this case, users are divided into three conditional groups: the first do not understand what to do if the android is out of order, the second run to the service center, and the last decide to reflash the device on their own. The last option is the most dangerous, because from ignorance of the cause of the breakdown, the phone can turn into a “brick” with no chance of recovery.
Decision
- Try to reboot.
- Take out the battery for 20 minutes.
- Pull out the memory card and SIM card.
- Leave the smartphone on charge for at least 3 hours.
- Try flashing Android.
- Give it to the workshop.
Software malfunctions
The main reason why the phone does not work after a hard reset is a failure in the operating system. It could appear due to the installation of unverified applications on the device from an unprotected source. You should not discard the option of an unsuccessful OS update when, at the time of its installation, the device was accidentally turned off or the battery ran out.
Attempts to return the gadget to service fail and the phone stops turning on. In this situation, only the firmware of the device can really help. Together with it, all software failures will be deleted from the device’s memory, and the owner will receive a clean system.
It is worth mentioning the android owners who independently installed the incorrect firmware for themselves, which can also become a reason to refuse to boot the Android OS after a hard reset.
A nuance can be a factory reset through the gadget interface. Perhaps the problem can be solved through a deeper reset operating system, which are performed by entering a special code for a specific firmware version or gadget model.
If you still managed to turn on the device, check it for possible viruses that can hinder the operation of the software. Also, you may need programs to check the integrity internal memory. Due to its damage, unforeseen malfunctions occur that cannot be determined without a thorough diagnosis.
Important nuances of resetting settings
Anyone considering a rollback should keep a few rules in mind to keep their Android device running.
- Before making a hard reset, prepare the charger. If the battery runs out at the time of the system rollback, harm will be done software. It has already been said earlier that in this case, only the firmware of the device can correct the situation.
- Even with a charger on hand, it’s better not to risk it and fully charge the battery. This advice is especially relevant for those who chose the usb connector on a PC or laptop as a power source. It is not able to provide the required voltage, which is why the gadget will not be able to make up for the full amount of energy expended and will simply turn off.
- Do not forget that when resetting the settings, all files in the internal memory are deleted. To avoid trouble, the information can be copied to cloud storage, to a memory card or PC.
- Users who do this for the first time should follow the system rollback instructions provided by their device manufacturer. This will avoid difficulties with the operation and the loss of important contacts.
- If you notice that the battery behaves inadequately, independently replenishes the energy spent or sits down even when charging, it is better not to risk it and postpone the reset until you get a new battery.
Conclusion
Modern devices may have problems even after a full system rollback to the factory state. To avoid most of the malfunctions, you need to carefully study the above rules.
There may be several reasons why the phone refuses to boot: hardware equipment or software failure. If a hard reset did not help you, you should not try to repair the device yourself. In a distress situation, if the phone does not turn on, the best way to solve the problem, there will be a visit to the service center, where professionals will deal with it.

Viruses
If the phone does not boot, it is possible that the operating system files have been corrupted by some kind of virus. Here you will need to flash the phone. In some service centers specialists will be able to restore the phone's performance 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.
