So my phone is almost 2.5 years old now, and I decided it was time to change out the battery (3G S). Everything went smooth but as I try to text on it now, the screen can sometimes glitch up. For example if I'm hitting the backspace button it will tweak and hit L like 6 times in a row. The same applies if I'm hitting another character, it will glitch a bit and hit another character in that vicinity. I know it's not my fingers messing up, and I can still send out successful texts - just with a little more effort. Like if I do it slowly it generally works fine. Do any of you fellas happen to know which little tape connector or what part internally governs the touch screen? I had some trouble connecting some of those things back in (like 1, 2, and 3 stickers for example) and I'm thinking maybe something is a little messed up. I'd like to be able to isolate the problem and see if I can fix it. Any help is greatly appreciated. EDIT: I figured out that the only part of my screen that glitches is the bottom portion of the keyboard. That goes from caps lock through ZXCVBNM and space. If I hit too high on any of those it will click that letter and the one above it. If I hit too low on one of the letters above it, it'll click that one and the one below it.
