Touches on Samsung Galaxy S9+ inaccurate
My parents both have the above phones, which I help them with remotely via TeamViewer. Screen touches do work, but are only accurate at the very top left of the screen.
The further I am from the top left of the screen on the control program (Android or Windows10), the touch on the remote device is closer to top left. I would guess the touch is around 90% of the way to where I think I'm making the input, regardless of where I touch on the screen. This makes controlling the device next to impossible, which is an issue for my Dad's phone as he's in early stages of dementia, so struggles with the phone if I can't set it back to his default view for him.
Am I doing something wrong here? Or is the Galaxy S9+ not fully supported. I've tried using different home screens on the devices. I've tried different display zoom settings. Nothing works.
Testing on my Galaxy S20 Ultra provides excellent experience with the touches being exactly where I have expected them to be.
