So my Note 20 Ultra has been having screen sensitivty issue when I charge it over cable. Like the sensitivty of it just drops in general which makes it impossible to play games while charging or even type to send messages. I know using the settings to increase screen sensitivity is one way but it just seems odd that this happens. Is it a software issue or hardware. I've been having this since day one. P.s the screen sensitivty drops so much that I can't like tap buttons in games unless I spam press the button. That's how bad it is.
I've tried 2 different chargers with 2 different cables. Both resulted in the same issue. I'm also noticing a weird thing where if my phone is plugged in, scrolling horizontally while the phone is in vertical mode cause the screen to freak out a bit. Like if I'm going through instagram stories, and i hold a story halfway, it starts to jitter a bit. This is the same for even the home screen or any other app. I think it's a hardware issue. I'll go to samsung to see what they can do about this.
I also having this issue and write to their facebook. The team called me yesterday and explained to me it is because the CPU will running low when charging. It is to protect the battery but I dont think this is a valid reason. I asked him is all the note 20 ultra has this issue, he said yes and told me "You know right, can't use phone when it is charging"... what a good reason...
I have this issue as well with the note20ultra. Over sensitivity only when charging. I wonder if it could be connected to the screen protector? The spend works fine by the way, it's only when using fingers.
It seems Samsung doesn't care, this is a serious issue specially fir gaming , the stupid 120 hz fresh rate get rediculase when it use battery more with HD+ , so why you made a 120 hz screen when it's not usable while charging ? Sorry my bad you want that 1400 $ !!!
It seems this issue is also occurring on the S20 FE.
I am having the same problem,brought my note20 ultra to the Samsung center but they only can "calibrate" the screen for now,which kinda stupid.An expensive premium phone having this issue is funny,felt like using a cheap phone during charging or when the phone have warm tempeture.It was super annoying caused by a very simple issue,FIXED THIS A.S.A.P SAMSUNG!!!
