OK this is driving me crazy. The problem i have is when txting on my gs3 using the samsung qwerty keyboard. I try to press period key on my touchscreen it 99% of time selects letter M. When turned sideways in landscape mode it won't do it. I have sat the phone on the table and very carefully tried pressing where the period key is. I'm very clearly not touching anywhere near the M but it selects M. This also happens 50% of the time when pressing backspace and it selects L. I don't seem to have any other issues with the touchscreen as far as touching somewhere and it thinks im touching somewhere else. All the other letters work fine. I have had other people try it with smaller fingers. Anyone else having this issue and know of anything to do besides resetting the entire phone??? I can't seem to find anything online.. THANKS!! ALSO if I press ABC to switch it from letters to punctuation. I can press period just fine.. It doesn't try to press ? But as soon as i switch back its pressing M again.
