This is yet another Tecno issue that has caught our attention so we'll keep updating this thread. If you've noticed your Tecno phone opening / closing apps , typing or sliding the notification bar up and down really fast (flickering) by itself then here are some fixes to try:
Check for scratches / particles on the screen
Scratches / particles on the screen could trigger unpleasant touch events. Ensure to clean the screen with a soft damp piece of clothing
Sleep the phone for a few seconds
This is a temporary fix. When the auto-selection / flickering begins, press the power button just once to make the phone go to sleep then wake it up with the power button.
Wipe data / cache
Boot into recovery mode after backing up your contacts then wipe data / factory reset. Clear cache also
