My pen works fine but randomly the screen becomes less sensitive to touch but when i try with pen it works perfectly fine. Only occurs while on fingers randomly not on spen. To notice it clearly or what unresponsive means, is through gaming. Any shooting fps games while swiping just after 20 25 seconds or so does the issue or so whereas when i swipe screen with spen its buttery smooth but with fingers feels like there's some sort of friction between the input touch and output touch response or decrease in screen senstivity but as soon as i lock and unlock the tab, the problem vanishes and again after 25 30 seconds persists like a constant loop! Even sometimes occurs on safe mode ie. not just third party apps but system apps as well like notes, google, pdfs where swiping screen comes to play. Tried every troubleshooting stuff cleared cache and all. Nothing helpful yet even took to service centre, they are not been even able to fix this. I got this recently on june 2021 with android 11 factory shipped. Got updated by security patch the latest available of May 2021 for this device by the service centre itself ie. through their system but nothing seems to solve this issue yet. I just wonder are developers working on this issue or not! Even i asked them to downgrade to android 10 that might clarify is it a software bug or hardware issue but says we dont have authority to downgrade and all. When i checked here the ones got this tab recently in 2021 are having this issue so might could be an android 11 bug or so. Lets hope it gets patched soon. Not able to enjoy this tab like gaming even on least possible settings and i know that exynos is capable to run games like pubg smoothly on least settings referring youtube reviews and games really run smooth i have tried no lags but this random issue, initially works buttery smooth and notes its not a major issue we don't need, swiping twice thrice for a single swipe isn't that frustrating but when comes to gaming it is a very very major concern! Pls help samsung as spen works fine only issues on fingers! You can also call this touch lag, screen unresponsive........, decrease in screen senstivity at random times... etc.
