I got my evo swapped a few days ago and at random times ill have sensitivity issues where I can't hold a button down when I'm testing to get a question mark or hold the delete key it will only let me touch for a second. And it also doesn't get certain thinks I touch so I have to continually touch till it responds. it randomly comes and goes and it takes more then one battery pull usually to get it working correct. Could this be a update/software issue or hardware. Should I swap it
