I purchased it and installed it last night. The issue I'm having has to do with the soft key buttons at the bottom of the phone after you unlock the phone. They work like they're supposed too but right after you unlock the phone they don't vibrate when pressed unless you hold one individual button down for 10 seconds or so. After 10 seconds it will vibrate and then function as it should until you lock and unlock the phone again. Ive done a battery pull and that didnt help at all. So what and where should I look at next? Has anyone experienced this?
