How to short-circuit the phone so it turns on. Turning on Android without the Power button
Sometimes users complain that the power button on their phone does not work. Why does this happen? How to fix the situation? How dangerous is this phenomenon? All this will be discussed further below. It's actually simple to understand. Especially if the power button is to blame.
Battery
The first scenario occurs quite often. Moreover, it has nothing to do with the breakdown. Why doesn't the power button on my phone work? The culprit may be the device's ordinary battery. The thing is that insufficient battery charge renders the smartphone inoperative.
Because of this, it turns out that the power button does not work. Actually this is not true. It is enough to turn on the phone to the network for a few minutes, and then try to work with the equipment again. If the problem lies in a low battery charge, then everything will work.
Real damage
But this is just the beginning. In fact, many users confuse situations in which the power button on their phone does not work, and when the device simply does not turn on. In principle, the result is the same - the gadget becomes a useless piece of plastic and iron.
In some cases, the power button may actually break. This is a very common problem. It occurs mainly among those who either work carelessly with the device, or for a long time uses it. It's all due to normal wear and tear.
If the problem is truly broken, it can be repaired mobile phone. Repairs are carried out in specialized centers. As a rule, for a fee you can pick up a working smartphone with normally functioning buttons.
Sometimes equipment cannot be repaired. What then? If the power button on your phone is broken, so much so that it cannot be restored to working order, you will have to buy new gadget. Fortunately, such a situation does not occur too often. You can usually contact the service center to fix your phone.
Software problems
Is the power button on your phone not working? As already mentioned, users often confuse the malfunction of the smartphone and the breakdown of the gadget’s control buttons. The second scenario is exclusively mechanical damage. Usually they are either corrected at service centers or lead to the need to purchase a new phone.
If we consider the problem not as a failure of the power button to work, but as the fact that the smartphone itself does not work, the reasons may lie, for example, in software failures. For example, the phone settings get lost under some circumstances. Or viruses damage the gadget's OS. Then it won't turn on. Or it will constantly turn off. In this case, the power button will also not work, nor will it respond to sent commands.
The situation is resolved if there is suspicion of software glitch in several ways. Namely:
- Flashing the phone. This can be done either independently or at service centers. It is better for novice users to entrust their mobile phone to professionals. Repairs, expressed by firmware, are carried out in a few minutes. The gadget will work at full capacity.
- Configuring already turned on equipment. Usually, users themselves carry out the so-called “Hard Reset”, and then begin to adjust the operation of the device. The power button should work after resetting the phone parameters to the initial level.
- Checking your smartphone for viruses and further getting rid of malware. If the gadget has already turned off and it turns out that the power button on the phone does not work, it is best to take the equipment to a service center. They will quickly help you rectify the situation.
All this helps with failures caused by the phone's operating system or its software. But that's not all. It is necessary to get acquainted with other options for the development of events.
External influence
Why else might the power button on your phone not seem to work? It is likely that the device was subject to negative external influence. And this led either to system failures, or to hardware damage. Because of this, the power button may actually not work.
For example, the phone was dropped into water. Or the gadget fell from a height to the floor. These reasons lead to damage to the smartphone. And it stops working. In the first case, you need to disassemble the phone as soon as possible and dry its components. After that, reassemble and try to turn it on. In the second case, it is better to immediately contact the service center if you discover a malfunction of the phone’s navigation buttons.
Results
What conclusions can be drawn? The power button on the phone often does not work because the gadget itself refuses to function. The most common reasons for this behavior are:
- mechanical damage;
- manufacturing defect;
- external negative impact on the phone;
- low battery charge;
- viruses on the phone;
- system failure;
- need for flashing.
If you find problems with turning on the phone, it is recommended to charge the battery, try to work with the smartphone again, and then take the device to a service center. This is the most the right way equipment repairs.
Dropping your phone from a height, getting liquid on it, and other unpleasant accidents usually lead to damage to the device.

Some models have a function automatic switching on when connected to charger. Even if our phone does not belong to this lucky category, we still turn it on for charging and hold down the side button, which controls the sound.
Sometimes this is enough to start the phone booting.
Connecting the phone to the computer
This method only works if the battery has at least 5% charge left, and not with all models.
We connect the phone to the computer via USB cord- this might work to automatically start the Android download.
USB Debugging Mode
If your phone was in USB debugging, then after connecting to desktop computer or laptop, you can try to start the download using the computer's command line. 
After this, taking advantage of this fortunate opportunity, you need to immediately install the ADB utility on your computer, i.e. Android Debug Bridge, with which you can control your phone via a computer and register it in command line her windows adb reboot. The phone screen will be unlocked, and you can change the settings, adapting the device to work without a power button.

Call the phone from another number and go to settings during the “conversation”;
If the camera is controlled by a physical and not a virtual button, then launch the camera, and then exit through it to the main menu.
Once the screen is unlocked, you should consider changing the unlocking method in the future.
Applications to quickly unlock the screen
So that in the future you can use the phone without resorting to exotic ways launcher, you can install one of the quick screen unlock applications on it.
- Gravity Screen - On/Off uses a gyro sensor to turn on and unlock the screen. While the phone is in a stable, stationary state, its screen is turned off and locked. But as soon as you pick it up, the lock is removed and the screen turns on. The application allows you to set the most convenient inclusion parameters. 
- Power button to Volume Button transfers the functions of the power button to the volume key.
- Shake Screen On Off – useful application, which turns on and unlocks the screen, you just need to pick up the phone and shake it lightly. Likewise, the screen turns off after use.
Whether it's old or new, gadgets break, and smartphones are no exception. A simple fall onto a hard surface is enough to cause damage.
Smartphones are fragile by nature. Even if they don't break, they are susceptible to many problems. One such problem that is very common among Android users, is the case when the power button stops working.
Think about it, the power button - the button we press countless times a day - stops working. This is enough to create chaos in our lives. When you press a button over and over again, you can expect it to stop working one day.
This doesn't happen to everyone, but those who experience this problem know how difficult it can be for your phone. Here are some solutions for this annoying problem.
1. Automate the on/off function with Gravity Screen.
Gravity Screen is an amazing application. Usage various sensors The phone turns the screen on and off. A feature like pocket or desk sensor involves detecting when you're holding your phone and when you're not. It learns to understand when you are going to use the phone and turns it on or off accordingly; to be honest, it always works, but the accuracy may vary from device to device.
If you're not particularly interested in how the app works and just want it to turn your phone on and off, then go ahead, download it and it will work great without draining your battery excessively if you set it up correctly.
2. Moto display
The app is limited in that it can only be used by Motorola device owners, but we had to add it to the list because it's simply amazing.
In Moto display you can see notifications without turning on the phone. But it can be used for more than just viewing notifications. Just don't touch your phone for a few seconds and then pick it up and you'll see the Moto display turn on. At this point, you can swipe down towards the lock icon to unlock it. Works great.
Moto dispay does not lock the phone; this must be done manually. But since the power button does not work, we recommend setting the phone's sleep time to a minimum, that is, 15 seconds.
3. Switch Power On/Off to the volume button
Yes, you read that right, there is an app for that too and the best thing is that it works even if the phone is not rooted. This application is called Volume Unlock Power Button Fix, that is, “unlock the volume, fix the power key.” This is very, very long name, but it completely defines the purpose of the application.
First of all, install it on your phone. Now open the application and give it administrator rights. This is necessary, otherwise the application will not work. Open the app and turn on "Enable Volume Unlock" and "Screen off" using the switches on the right. If you have enabled both options, then you will be able to turn off the screen in the notification panel and turn it on using the volume button.
In the app settings, you can also enable features such as automatic start at boot and auto on/off, which will work in the set time interval. For example, by setting the time from 06:00 to 04:00, the application will only function during this time.
We used it for 2 days and didn't find any unnecessary battery drain. This is an amazing app.
As a result of severe physical impact or at the end of its service life, mechanical button Power on mobile device may fail.
