I have used a headset and it has less issues.
The odds of having 4 with the EXACT SAME hardware issue is very unlikely. Thats why most of us are leaning towards some type of app/widget or other miscellaneous issue such as a case or skin.How likely is it that Droid 5 won't have this issue, though? Could it be a batch issue and if so, could it be that all four came from the same batch even though one came from a different state?
