The
mobile display screen is directly connected to the motherboard via digitizer.
Whenever there is slight damage on the display screen, it can greatly affect
your touch response. In this tutorial, we are going to help with such mobile phone repair and
touch screen problems on Android smartphones and tablets.
Some
of the most common touch screen problems are:
1. The
touch screen has stopped working and does not respond to any taps.
2. The
touch sensor is not properly functioning as if you type 'J' it shows 'B'.
3. Touch
screen lags.
Why
is the touch screen not working?
The
touchscreen might not be working due to a number of reasons. Some of the most
common reasons are:
1. Physical
damage: touch screen is broken or damaged. High temperature, cold, moisture,
the magnet can also damage your touch screen
2. Malicious
applications that crash the phone making it unresponsive.
3. The
Android OS crashes after a firmware update.
4. A
wrong setting.
If the touch screen has stopped working
for no reason at all, then it is caused by malicious software. If you have
physical damage on the screen, then it is high time that you perform a screen
repair.

A diagnostic check of the touch screen will not
fix the problem but will help you identify the areas where the screen is
unresponsive. to access the diagnostic tool, you will need to know some
specific code in the phone dial.
