I always encountered this problem on Techno and Infinix phone . I initially thought it was a software issue before I later detect its an hardware fault.
There is always a Sensor behind the Touch Pad of the phone with this condition and the Sensor is always a trace on the Pad beside the front camera.
Gently removing this sensor,the problem is solved.
Note;It always happen to a phone with a Changed Touch Pad and not new phone.
