Poor screen calibration in Samsung Galaxy Note 1717

My Galaxy note acting weird now. I really don’t know what to call this. I hope that it can be fixed. The issue is when tapping fingers on the screen close to each other, the phone will think that you are touching between 2 points. It is somewhat same what we saw on old single-touch resistive touchscreen. It makes me totally annoying when using a portrait keyboard.

I assume that you are talking about the S Note app here. I think that it could be bung in the app. Moreover I didn’t see multitouch support for this app at all. As far as I know that it accepts input with the single tap only. If you want to check it, you can try using the Multitouch Tester which is available in the Android market.
