Hello,
Please record and share a video showing the incorrect working of your touch screen to let us see how your issue looks like.
To rule out the possibility of an existing software error, I suggest you to flash your phone with SP Flash Tool, choosing the 'Firmware Upgrade' option in the flasher application. That process will completely rewrite the whole software content of your device. - You will lose your user data.
