Well my phone came back really quick from official Samsung Service (it took them about 1 day) which was nice but the papers that came with it said that they had to replace the s-pen..and also had to install a brand new screen!!!!! which was kind of dissapointing because it was a brand new 2 day...
Re: touch screen problem when using S pen.
nearly the same problem here...when i try to draw a line vertically from top right side of the screen to the low right side..somewhere in the middle the line deforms :(
my phone is like it has a fat vertical line to the right side that's a blind spot...
