Sometimes my s21 Ultra's screen is unresponsive and I need to tap twice or even three times before it works. It mostly occurs when going back to the home screen from an app. Once at the home screen, when I swipe up to open app drawer or swipe to either side, nothing happens. I have to wait a second and tap again to get a response.
I have tried everything even down to a factory reset which seemed to fix the issue though only temporarily. It came back after a few hours. I only have a small handful of apps installed (Instagram, BBC, etc) and am using the stock launcher. I've looked though display settings, played with battery settings, refresh rate etc and I can't seem to find a fix.
Does anyone else have this issue or know what to do?
Trouble shooting could be a long process. After every thing you've tried, i would perform a reset all settings and test. I would change refresh rate/ screen resolution and test, remove swipe gestures and use app button and test. Remove ALL 3rd party apps (since you don't have many) perform a cache partition wipe in recovery and test . Back up and factory reset and test without restoring anything first. Then i would probably give up 🤷
