Why the touch screen does not work and how to fix it

Whether the functions of the sensor work well depend almost entirely on the touch screen of the device, but usually, problems with the screen are easy to handle, just by cleaning the screen and Make sure your hand has no way back to the screen, and you have installed all the latest updates.

The first thing you need to do is wipe your screen and hands. The touch screen does not work well when they are wet or dirty and you cannot use the touch phone if your finger is wet, dirty or wearing gloves. If there is liquid on the screen, or any other substance like food, the first step is to clean it. If after cleaning the touch screen still does not work, turn off the device and turn it on again.

Clean the touch screen

In some cases, the touch screen will stop responding due to dirt, dirt in the phone cover or screen protector.

Step 1: Wash your hands or wear clean gloves.

Step 2: Wipe the touch screen with a lint-free cloth.

2. Never use a wet towel.
3. Always squeeze towels before using on the touch screen.

Step 3: If the touch screen still does not work, remove the screen protector or phone cover.

Step 4: You must clean the screen after removing the screen protector.

Step 5: Remove gloves because the touch screen does not work well with gloves.

Step 6: Make sure your fingers are clean and dry because wet fingers often lead to inactive touch screens.

Step 2: If the phone does not turn on automatically, wait about a minute and press the power button again.
