Nowadays, it is rare for our phones to have physical buttons. But we still rely on buttons for basic actions like waking the screen and adjusting the volume. Because we interact with them many times a day, mechanical buttons can wear out over time.
If your Android phone's buttons don't work, try one of the tricks recommended by Make Use Of to solve the problem.
Make sure the buttons don't really work
A software problem is likely to cause your button to malfunction. To make sure that the button does not actually work, it is advisable to go through the following basic troubleshooting steps.
Restart your phone.
Restart your phone to restart all services running in the background and update the main components of your phone in case something goes wrong. If the Power button doesn't work, you can download the Google Accessibility Suite Google app. Once installed, activate the Accessibility menu from Settings -> Accessibility. There will be a new shortcut on the navigation bar that looks like a man with outstretched arms. Touch it, select the “Power” option and press “Restart” from the menu that opens.
Load in Safe Mode.
Another way to test whether a bug is causing your button problem is to load in safe mode. Basically, safe mode is an isolated environment that limits your phone to the software it originally came with. Therefore, none of the third party services and applications you have installed will work in safe mode. If the button in question functions normally in safe mode, you know for sure that the culprit is a third party service.
To get into safe mode on most new Android devices, press and hold the power button. In the resulting menu, touch and hold the Power Off button. Once you accept the prompt, your phone will restart in safe mode soon. To exit safe mode, repeat the procedure, but select the Restart option.
Diagnose the hardware buttons on your phone
The last method to confirm that your problem is due to a hardware failure is by diagnosing the buttons on your phone through a third party application. To do this, install the app called TestM from the Play Store. Launch it and touch Hardware from the homepage. Then select “Hardware Buttons” and follow the instructions that will appear on the screen. If TestM is able to detect your buttons, it will mean that your problem is due to the software.
Based on these tests, you should get a clear idea of whether your phone button is actually damaged. If this is a software error, uninstall recently installed applications, as well as any that you do not trust or have not used for some time. If this is not possible, perform a full factory reset from Settings -> System -> Advanced -> Reset options.
Clean around the buttons
Your phone's hardware keys are regularly exposed to dirt. In this way, the gaps around them may have accumulated dust and dirt, which can interfere with internal connections.
Although you can't do much here without professional help, try blowing the dust out of the potentially affected areas with compressed air and cleaning them with a toothpick.
Replicate the action of application buttons
Before seeking professional help, try to solve the problem with applications that can reproduce the actions of the buttons so that you can move forward without using the physical keys.
You can start with the Google application, Android Accessibility Suite, which we discussed above. The app adds a shortcut panel for a number of key features.
If the Power button does not work, waking your phone from sleep is your first problem. In this case, you can install an application like Gravity Screen, which recognizes the movements of your phone and can wake it up as soon as you pick it up. The app is even able to lock the phone when you put it in your pocket or on a table.
If you're looking for an alternative to the malfunctioning volume buttons on your phone, try the Assistive Volume Button app.
Try to remember that you have not wet your phone
If your phone buttons stop working after getting wet, you should do nothing before making sure your phone's interior is completely dry. There are various methods for rescuing a phone dropped into the water. Turn off your device immediately, allow it to dry completely, and then you can begin troubleshooting.
Seek professional help
Your last decision, of course, is to visit a workshop and get professional help.
