But just like any of the smartphone components, the touch screen is also prone to malfunctioning, and it can be very frustrating when the phone touch screen is not working. To help you get rid of this frustrating situation, we've prepared some of the common causes of a malfunctioning touch screen and trusted solutions to fix TECNO phone touch screen not working or responsive.
Check any dust on the proximity sensor
One of the causes of an irresponsive touch screen is a malfunctioning proximity sensor. The sensor is located near the front camera, and it performs its job for turning off the screen upon contact to an opaque object during calls. However, it may also lead to a phone touch screen not working if something is blocking it - probably dust or pocket lint.
To get your TECNO touch screen working again, turn off the screen and try cleaning the sensor (upper part of the screen) by clean soft cloth. You can use wipes or soft cloth wetted with alcohol, but don't let it be too wet and make sure you do it gently and do not scratch the sensor in order not to cause a bigger problem.

Thick screen guard on the sensor
Arguably, 60-70% of smartphone users today do apply a screen protector to give a further layer of protection in case of accidental drops or scratches. But an unresponsive phone touch screen can emerge from there if the screen guard is too thick on the sensor - it decreases the touch sensitivity.
If you've cleaned the proximity sensor and the whole screen itself but the touch screen is not working, try to gently remove the screen guard and clean the screen itself. Try touching the screen now if it works.
Any damage on the touchscreen?
Even if you applied a screen protector earlier on your TECNO phone, there's the possibility that you'll still have a broken screen. Though, when your touch screen is broken, it might still work for a few days or even months, but it will stop working after. So, if you have any crack on the touch screen, the problem is probably coming from there. You will need to see a phone repair technician who is capable of fixing the screen for you.

Check if any physical key is pressed by mistake.
Hardware keys can also cause the touch screen to stop working. This normally occurs if you have a case on your phone that is pressing the keys by mistake. Try removing the case for a while, check and clean dust particles around the keys, and press them normally to check if they're still in good condition, and check if the touch screen is working now or move to more technical solutions below.
The liquid in the USB connector.
Also, moisture or liquid in any part of the phone, especially the USB connector, can trigger TECNO touch screen not to work. Try to clearly observe and dry your TECBO phone if you were trapped in the rain earlier or you mistakenly splash water on the phone.
If there's moisture or liquid in the USB connector, a quick visit to the service center is required because it is likely to have affected the touchscreen.
