Method 1: Restart the Phone to Fix Touch Screen Not Working
In case the issue is caused by a minor glitch, like your phone’s screen just suddenly goes unresponsive, a restart should fix it. Doing a restart will refresh the system and get rid of bugs and errors. But how can you restart the phone if the screen doesn’t work? That’s simple:
While the screen is awake, hold the Volume Down and the Power key for 10-15 seconds. Then, release them when you see the phone’s logo and model on the screen.
Wait for the phone to completely boot up. When it does, touch the screen and see if it responds
Method 2: Update Android to Fix Unresponsive Touch Screen
If the issue is deeply rooted in your phone’s Android version or the last update on your device, the only option is to update it. It’s the manufacturer’s fault, not yours. Typically, they would send out bug fixes and patches to resolve the issue.
You can bring your phone to their service center to let them do the update if the phone is still within the warranty period. Or you may do it yourself using an OTG adapter and a wired/wireless mouse.
Connect the OTG adapter to your Android phone’s USB port. Then, link your mouse to the adapter. The phone should detect the mouse shortly after and you will see a cursor/arrow on the screen.
Next, use the mouse to connect the phone to a mobile network or WIFI. When connected, navigate your way to Settings and then to Software Update.
There, tap Update. The phone will check whether there’s an available one. Download and install it if there’s one.
Before you do this, make sure that your phone is charged 50% and up. The update process may take longer and you wouldn’t want it interrupted as it could further damage your phone
Method 3: Factory Reset Android to Fix Touch Screen Not Working
If an update is not available, your last resort to fix the software glitch that’s causing the screen to stop working is a factory reset. This process involves erasing all your phone’s data and restoring the device to factory settings before the issue occurred.
Since the touch screen doesn’t work, you will do this via Recovery Mode. This may not work for all Android phones, but it’s worth a shot.
Hold the Power button until your phone reboots. Then, hold the Volume Down button until you see a logo on the screen. The Recovery Mode menu should appear momentarily.
In there, use the Volume buttons to navigate the list and the Power key to select. Choose Wipe Data/Factory Reset. Then, confirm Factory Data Reset. The process will commence right after.
When you see that the process is complete, select Reboot System Now to restart the device. Then, check if the reset fixed the issue.
As mentioned, resetting your phone will delete all your files. If you have important data, make a backup first. You can use the OTG method to control the device and back up your files manually. You may also try using Android Backup to make it much easier for you.
