Got a wierd problem. I replaced a cracked display in my wife's iPhone 5 and now the touchscreen is having issues. It happens like this: 1. Hit the home button, lock/unlock button or a call comes in 2. touchscreen doesn't respond 3. hit the lock/unlock button to lock the phone 4. hit home button or lock/unlock again 5. touchscreen works perfectly now Happens every single time. With or without case. I was wondering if it might be a grounding issue, but not sure how to fix it. What's the deal?
