The sensor works correctly only when you press on the cable, how to fix it?

Question

Mobile devices

I dropped it, broke the touchscreen, ordered it through aliexpress and replaced it myself.
After glitches appear, the sensor reacts poorly, and when you press on the place where the sensor cable is, everything is fine.
I tried to put a pillow on the inside of the case where the cable is to squeeze it, but it doesn’t cope well.
Who came across, I ask for help
