Since this issue was different from the other touch issues I am posting it as a separate thread. I searched over internet and found that some other people have it but I could not find any answer if this is a hardware issue or software issue. My issue is like the following one:
"I am having touch screen issues, although different to what you are experiencing. My problem is with the lock screen when using pattern to unlock, the screen does not register my finger and I either have to repeat 2-3 times and push down hard or else use the s-pen."
which was at: http://forums.androidcentral.com/sam...-1-2014-a.html
I also noticed that when I swipe between home screen pages when I keep a page in the middle some times my figure is ignored and the page flips.
Is this a non issue? is it a hardware or a software issue? is there any solution for this?
