If your power or volume buttons are not working, then don’t rush to the service center yet.
Let’s take a look.
Check That the Buttons Really Are Dead
First of all, verify you’re using the buttons properly.
By default, it either turns off the display or activates the Bixby voice assistant.
For new users, this can make it look like the Samsung power button is busted.
Most phones will automatically power on when they begin charging.
To check that the key really is broken, we recommend going through a few basic troubleshooting steps.
Reboot Your Phone
Your first order of business is to perform a simple reboot.
This will restart all background services and refresh your phone’s core components in case something has gone wrong.
This works if your phone screen is turned off and your battery is above 30%.
But what if your machine doesn’t have either of these options?
Another way to restart an Android phone whose power button isn’t working is to use the accessibility tweaks.
Go toSettings > Accessibilityand toggle on theAccessibility menu.
Tap that, select thePoweroption, and hitRestartfrom the menu that appears.
If you’re free to’t see this option, download Google’s ownAndroid Accessibility Suiteapp to enable it.
This is a stripped-back mode that runs the basic Android operating system and nothing else.
None of the third-party services and apps you’ve installed will run in safe mode.
You normallyenter safe mode on most new Android devicesby pressing and holding the power button.
Then touch and hold thePower offoption and follow the onscreen instructions to restart in safe mode.
To exit safe mode, just kickstart your phone again.
To do that, install a free app calledTestMfrom the Play Store.
Launch it and tapHardwareon the home page.
Next, chooseHardware Buttonsand follow the on-screen instructions.
Based on these tests, you should have a clear idea of whether your phone’s button is dead.
Just remember toback up your datafirst!
The gaps around them might have accumulated some minute debris, which could hamper the internal connections.
Sometimes this will be enough to get them moving again.
Also, remove your case and give that a clean, as it will collect dust over time.
Possibility of Water Damage?
Determinewhat your phone’s IP rating meansand then follow the rightsteps to look after a water-resistant phone.
If your phone’s buttons have stopped working after a water accident, you shouldn’t do anything yet.
First, you must ensure your phone’s internals are completely dry.
There are various methods to save a phone dropped in water.
Turn your rig off immediately, let it completely dry out, and then you might start troubleshooting.
Create Onscreen Virtual Buttons
Before seeking professional help, you might give virtual button replacement apps a shot.
Fortunately, there are lots of ways tounlock your phone without the power button.
On phones running Android 9 or above, the Android Accessibility Suite comes pre-installed underSettings > Accessibility.
Otherwise, it’s a free download from the Play Store.
TheAssistive Volume Buttonapp is for people who want a straightforward alternative to their phone’s malfunctioning volume buttons.
It sticks two floating buttons to the screen’s edge for turning the sound up and down.
In addition, you have the option to customize the virtual buttons' look, size, and more.
In particular, in the case of dead volume keys, a virtual replacement should do the trick.
Your last resort, of course, is to visit a service center and get professional help.
And they’re all perfectly useable, too.
