a couple weeks ago i noticed that when i would wake my phone and try to unlock my phone...i noticed that the slider would "resist" me and it would move but it wouldn't move all the way to the other side of the screen. the only way to remedy this would be to quickly press the on/off button on the top of the screen and then presss the home button again to re-wake the phone. at first i thoguht oh maybe my finger is greasy or too cold but nope even when my fingers are perfectly warm and degreased i find that it occurs at least once a day... i am beginning to think something is wrong with my phone??? could this be a software issue ? the touch screen works fine for the most part ive tried testing to see if the bottom portion of the screen has any issues while actually using the phone and it doesnt.. anyone else have this problem?
