Samsung phone without buttons. Turning on Android without the Power button. A way to bring your smartphone back to life
For example, the power button of a smartphone does not work. Crashed, broke, etc. And now the question arises, how to turn on the smartphone without this very button?
Old and new, expensive and cheap, on Android or iOS, trendy and not so - all smartphones and tablets can break.
Not in the sense of glitching and freezing, namely, fail, as a rule, as a result of sudden mechanical and other adverse effects. Sometimes -, but more often with less tragic consequences, one of which is just a mechanical failure, due to which the power button does not work.
It's a shame, annoying. It turns out that the device did not seem to have suffered much, but the sense from it suddenly became much less.
In fact, if you were “lucky”, say, to drop your smartphone (or tablet) so delicately that it was the power button that got the most, then this adventure, as practice shows, can develop for you along two storylines: the smartphone remained turned on, but you cannot unlock it, or it turned off completely, and now it is not clear how to turn it on, since the power button does not work.
Actually, the conditions of the tasks are formulated. Now you can try to solve them. So:
how to turn on the smartphone if it is off, the power button does not work
The current situation, of course, is not encouraging, but there is still hope. However, success is not guaranteed, since it will depend on the brand and model of a particular device.
First of all (and this option no. ) we try to connect the smartphone to a standard charger. This is in case it does not turn on due to battery discharge. Some models may automatically turn on at this stage (although, unfortunately, the probability of such quick solution problems are extremely low). We connect to the charger and hold down the volume control button for a while, suddenly the boot menu appears on the smartphone screen.
Option number 2 ... If the battery is not completely discharged (at least 5%, or better, more, the charge indicator is displayed even if the smartphone is turned off), disconnect the device from the mains charger and connect it to a computer or laptop via ... Our Motorola Moto G then turned on instantly without any buttons.
If yours has not turned on, then there is still option number 3 ... To be fair, let's call it a chance. Since it can work only if, before turning off the smartphone, you activated the USB debugging mode on it, and now you can try to turn on the device through the command line of the computer. In general, if the conditions are met, then install ADB on your computer and open a window with a command line. After that, we connect the smartphone via USB, in the command line we write adb reboot and click Enter.
how to turn on the smartphone if the screen is locked and the power button does not work
As they say, already lucky, so lucky. If the power button stopped working, but the smartphone did not turn off, then everything is somewhat simpler. But you still have to be quick and turn off the screen of the device so as not to waste the battery in vain (just in case).
Owners Samsung Galaxy and iPhones, you can not be very nervous at all, because even with a shattered power button, they can then unlock their smartphones and ... In addition, many modern models, including those with home button the design is not provided, you can wake up by double tapping on the screen (of course, if this option is active).
Another thing is when there is no Home and the screen does not want to turn on (or cannot). Then you need to either connect your smartphone to the charger, or ask someone to call it. Also. if the power button does not work, you can press the physical camera key, if any, thus launch the corresponding application, and then simply exit this program to the main menu. It is not very convenient, but then you can download a suitable program to quickly unlock the screen, which will significantly simplify the problem for a while. The main thing is not to forget about the battery level in all this fuss.
For example, the application Power button to Volume Button Allows you to emergency transfer the function of the power button to the sound control button; from Gravity screen the smartphone turns off automatically if you put it on a flat surface or in your pocket, and turns on if you take it in your hand; Shake Screen On Off - the screen can be turned on / off by simply shaking the smartphone slightly if the power button does not work. This should be enough for the time until you get to the nearest service center.
At some point, it may happen that the power key of your phone or tablet under android... Today we will tell you what to do if you need to turn on such a device.
There are several methods for starting a device without a power button, however, they depend on how the device is turned off: it is turned off completely or is in sleep mode. In the first case, it will be more difficult to cope with the problem, in the second, accordingly, it will be easier. Let's consider the options in order.
Option 1: Completely turned off device
If your device is turned off, you can start it using recovery mode or ADB.
Recovery
If your smartphone or tablet is turned off (for example, after the battery is discharged), you can try to activate it by entering the recovery mode. This is done like this.
Wait for the system to boot and either use the device or use the programs described below to remap the power button.
If you know for sure that YUSB debugging is disabled, then use the recovery method. If debugging is active, you can proceed to the steps described below.
Besides managing from command line, there is also an ADB Run application that allows you to automate the procedures for working with the Android Debag Bridge. It can also be used to force the device to reboot with a faulty power button.
Both recovery and ADB are not complete solution problems: these methods allow the device to start, but it can go into sleep mode. Let's take a look at how to wake up the device if this happens.
Option 2: The device is in sleep mode
If your phone or tablet has entered sleep mode and the power button is damaged, you can start the device in the following ways.
Connect to charger or PC
Most universal way... Almost all Android devices wake up when connected to charging unit... This statement is also true for connecting to a computer or laptop via USB. However, you should not abuse this method: firstly, the connection socket on the device may fail; secondly, constant connection / disconnection to the mains negatively affects the state of the battery.
Calling the device
Upon receipt incoming call (telephone or Internet telephony) the smartphone or tablet wakes up from sleep mode. This method is more convenient than the previous one, but it is not very elegant, and it is not always possible to implement it.
Wake up with a tap on the screen
In some devices (for example, from LG, ASUS), the function of waking up by touching the screen is implemented: double tap on it with your finger and the phone will wake up from sleep mode. Unfortunately, it is not easy to implement this option on unsupported devices.
Reassigning the power button
The best way out of the situation (except for replacing the button, of course) would be to transfer its functions to any other button. These include all kinds of programmable keys (like calling the Bixby voice assistant on latest Samsung) or volume buttons. We will leave the issue of programmable keys for another article, but now we will consider the Power Button to Volume Button application.
Please note that on xiaomi devices it may be necessary to commit the application in memory so that the process manager does not disable it.
Sensor wake up
If the method described above does not suit you for some reason, there are applications that allow you to control the device using sensors: an accelerometer, gyroscope or proximity sensor. The most popular solution for this is Gravity Screen.
Despite great opportunities, the application has several significant disadvantages. The first is restrictions free version... The second is increased battery consumption due to the constant use of sensors. Third, some options are not supported on some devices, while other features may require root access.
Conclusion
As you can see, a device with a faulty power button can still be used. At the same time, we note that no solution is ideal, therefore we recommend that you, if possible, still replace the button, either yourself or by contacting service center.
As a result of strong physical impact or at the end of its service life, the mechanical Power button on the mobile device may fail. It would seem that without this element it is simply impossible to turn on the smartphone, but in reality it is not. There are several ways to enter the device menu when not working key nutrition. Let's take a look at how to turn on your phone or tablet without the Android power button.
Ways to launch Android without the Power key
In theory, there are several methods for loading a gadget with a broken power button. However, it is impossible to give a full guarantee that at least one option will work. Much depends on the model of the mobile device and on what state it is in - active or off.
You can try to turn on Android without the Power key using:
- Charger and volume rocker;
- Computer and ADB debug bridge;
- Special software.
How to boot Android if the phone is turned off?
If your smartphone is inactive and the power button is not functioning on it, the first thing to do is connect the charger to it. On some models of devices, the operating system may start already at this stage.
If the desired does not happen, try holding down Volume Down (Volume Up) or simultaneously two volume keys while charging is on. These actions can load the environment recovery Recovery... This menu will allow you to reboot the gadget, that is, enter the Android graphical interface.
When the Power key is working, the smartphone is restarted through the resuscitation area by the command reboot system now. If this button does not work, after entering Recovery, wait a while - the phone should reboot itself.
Enabling a smartphone using the ADB debug bridge
Android Debug Bridge (ADB) is special programallowing to manage mobile device through a computer. With its help, you can unlock root-rights, change the firmware, enter Recovery mode and perform a number of other actions, including restarting the phone. The only condition is that USB debugging must be activated on Android. 
If you activated this function before the power button failed, we try to turn on the device using ADB:
Instead of ADB, you can use the ADB Run utility to enable the gadget via a PC. It is a simplified analogue of SDK Platform Tools, since almost all control commands are already written in its code. They only need to be started with a specific number.
To enter Android via ADB Run, you must:
How to download Android if the phone is in sleep mode?
If the smartphone is turned on, but is in sleep mode, it will not be difficult to get into its menu without the Power key. The main thing is not to allow a complete discharge of the battery on the mobile device so that it does not turn off.
There are several ways to activate the screen on Android:
- Connect the charger to the mobile phone;
- Tap twice on the display (this function is not supported on all smartphones);
- Press the mechanical Home button, if provided for your phone;
- Call the unit from another smartphone.
Your phone will now turn on with the volume rocker.
You can also turn on Android using the built-in spatial orientation sensors. To do this, you need to download the Gravity Screen program, and then adjust the sensitivity of the vertical and horizontal indicators for you. 
In Android OS devices, the power button has two functions - turning the device on and off, as well as activating and unlocking. The failed power button does not allow full use of the device, which is a direct road to the service center. If there is no workshop nearby or it is important to postpone repairs until a later date, in this article you will learn how to turn on your phone without the power button.
The phone is turned off, the power button does not work
First, consider the situation when the device is completely turned off, the power button does not work and we need to start the OS.
Method 1: connect to charger
When the power cable is connected, charging will start in the off state. However, some models load the system at the same time. If this does not happen, try connecting the device to the computer to turn on the phone.
Method 2: connect to the charger and hold down both volume control buttons
While installing the power cable, hold down both volume buttons and hold until boot menu - the phone will turn on, but then you will need to select the download mode, while different models phones may offer different options.
Selected for testing, the Motorola Razr M smartphone loaded Boot mode, where it is proposed to choose one of further action: Normal PowerUP, Recovery, AP Fastboot, Factoty and BP Tools. Disconnect the cable and select one of your preferences, such as Normal PowerUP to turn on the phone.
In my case, the smartphone loaded the system only when the “Factoty” item was selected. And when "AP Fastboot" was selected, the firmware mode was launched, where instead of booting the system, you can issue a reboot command. In this case, you will need a computer and the RSD Lite program, and you will also have to edit the file with the commands when flashing, but this is only if you have a Motorola smartphone. For smartphones from other manufacturers, appropriate programs are used.
If you managed to get into Recovery mode, then select the line - "Reboot system now". To confirm the action, you need to press the power button. And since the key is not available, it is hoped that the smartphone will perceive tactile pressure through the display. Third-party Recovery variations support clicking through touch screen; and only a few of the basic recovery modes. If the display does not respond and the power button does not work, then this option disappears.
Method 3: Wait for the alarm to turn on
Usually, an alarm clock has the ability to turn on the device to activate a previously set action, even when the phone is turned off. If a similar event occurs, take a moment to go to the menu.
Phone is on but locked
To unlock the screen, the device must be woken up, which can be easily done by an incoming call or by connecting to a charger. And what about the street? Of course, plugging in a portable charger is inconvenient every time. In this case, the methods described below will work.
Method 1: Using a biometric authentication system
Most modern smartphones come with a built-in fingerprint sensor or allow you to customize the Face ID system. The latter, to release the lock, uses the previously specified snapshot of the owner's face. If you set up biometric screen unlock, then you do not need to press the power button to unlock the screen. It should be borne in mind that some smartphones, in order to use biometric unlocking, first need to wake up the device with the power button.
Method 2: Turn on the phone with the MiKey button
A headset jack accessory contains a customizable button. In the application settings, the parameter is indicated - the number and duration of pressing, to lock and unlock the screen. This method will be a good alternative if the device does not have a fingerprint scanner or if the sensor requires waking up the smartphone. Also, the button will come down to wake up the device and then unlock it by internal means or biometrics.
Method 3: Turn on the phone using gestures
Some smartphones allow you to launch applications by entering a gesture of the corresponding letter - C, V, W or M. after it starts specified program, for example, a calculator that folds easily and does not interfere with the further use of the smartphone.
If you have a broken power button and try to turn on your phone, this is unlikely to work, but we can help. Today we will tell you how to turn on or wake up your phone without the power button.
Regardless of whether your smartphone is old or new, these devices sometimes break. One of the most common and annoying defects is the Power Button not working. After all, if you can’t turn on the device, it’s no more useful than, say, a paperweight. In this case, you cannot avoid going to the nearest workshop, and it is better to entrust the repair of sony xperia z or other Sony products to a branded service center.
If you are in this situation, there are two possibilities: your phone or tablet is on but you cannot wake it up, or it is completely off and you cannot boot it up. We will explain how to solve both of these problems separately below.
How to turn on the phone without the power button: the device is turned off
If you have a broken power button and your device is turned off, then you are in a difficult position, but there is still hope. Different methods will work depending on the device model, so we do not make any guarantees.
The first and easiest way to try is to connect your phone to a charger in case the battery runs out. Some phones may turn on immediately at this point, but this is unlikely, so try using a long press on the volume buttons to bring up the boot menu.
After slightly charging the battery, preferably 5 percent or more (the screen should show a percentage even if the phone is off), try disconnecting it from the charger and connecting it to your PC or laptop via USB. We tried this with a Motorola Moto G and the phone booted up instantly.
Another option will work if you enabled USB debugging before the device was turned off. It consists in using the command line. Install the ADB program on your PC and open a command prompt window (instructions can be found on our website). Once you've done that, connect your smartphone to your computer, type "adb reboot" and hit enter.
How to turn on the phone without the power button: the device is turned on
If you're lucky and your device is still on, but the power button isn't working, then things will be much easier. For starters, don't let your phone or tablet turn off due to low battery power.
For some phones, such as Samsung Galaxy or iPhones, a broken power button will not be a significant inconvenience because the physical button Home under the screen will wake up the smartphone. Depending on the device, you can also wake up the phone with a double tap on the screen. However, most Android smartphones do not have physical control keys, so there is no way to wake them up.
There are several ways to force the phone to wake up without using the power button. Try to simply plug it into a charger or have someone call you. If you have a physical camera shutter button, you can use it to launch the camera app and then just exit it.
Not all of these methods are convenient to wake up your phone without the power button, but as soon as you turn it on, install an app that will help you in the future. But still, remember that you must not allow the device to shut down due to low battery.
The Power Button to Volume Button app does exactly what you'd expect from its name. Another app - Gravity Screen will put the device into sleep mode when you put it down on a flat surface and turn it on when you pick up your smartphone. Alternatively, consider Proximity Actions, which will control your phone using a proximity sensor.
