========================================
I just replaced my phone's screen at a local phone repair place and they replaced my screen with a local off-market one. Its display and touch resolution are good but it becomes awful when I move my finger slowly across the screen. It happens throughout the entire phone and it seems like the display updates only when I move my finger in 20 pixel increments. I have attached a recording of the problem with the my touch locations visible for a better understanding of the problem. Even with the locations visible, my finger was actually a few dozen pixels ahead of the spot I was supposedly at so there also seems to be a ghost touch issue.
Things I tried:
Rebooting
Clearing the system cache
Disabling developer options
Thank you in advance for any help you can provide.

Hello MiniLink,
Thank you for providing the video.
Did you repair it at an ASUS official repair center? If yes, please provide the RMA number so that I can help you confirm the repair status.
To fix this issue, you can also try to restore your phone to factory settings. Please make sure that data backup has been completed before restoring your device..

Hi, thank you for your response. Unfortunately I don't speak chinese so I had to go through google translate first. If I understood right you're asking me if I went to an ASUS repair shop and to try to factory reset my phone. I don't have any official repair shops near me so I didn't try that but it seems like it's worth going through the effort. I will also try to factory reset my phone and keep you posted!
