[Q] Touchscreen edge margin

---

My Note seems unable (or unwilling) to detect touchscreen contact within a relatively small margin of each edge.

Using the 'Pointer location' option in Developer Options, I can see that no matter where along the edge I put my finger, it seems to clamp it to 20px away from the edge. Taking the left edge, for an example, I can see the line tracking my finger up until I hit the margin, and then it will go no further left. It is still detecting the press, though, moving my finger up and down will result in a perfectly straight line being drawn parallel to the edge of the screen.

I'm using PA3 (RC3). Either the problem doesn't exist or I just didn't notice on stock. I only became aware of it when attempting to mess around with the new 'Pie' thing in PA, and realising that it's somewhat difficult for PA to detect the gesture when the edge of the screen isn't registering the touch!

I'd appreciate it if anyone could quickly check whether their Note has the same issue, or if anyone is aware of a way of expanding the area on which touches will be registered.

try the touch screen benchmark app found on the play store to know if you have any problem with the touch screen

I wasn't sure to which app you were referring, but I found one that was able to fairly clearly show the issue. I took a screenshot and attached it to this post.

Each of those lines was drawn from or to the edge of the screen. You can see they all stop significantly before the boundary. The app is ScreenTouchTest, if someone would mind repeating the experiment and seeing what results they get!

Same thing happens with me. However, when using the S-Pen, the boundary gets to the right, ie the screen area increases. Here are two screen shots, one with finger and the other with S-Pen.







P.S: sorry for the big pictures...
