Hi There, Just recently switched from an iPhone to Android and the S4. Love the phone and the OS, but having an issue I am hoping somebody with experience can assist me with. Phone is setup with my companies exchange server. This restricts my ability to alter the lock screen, add widgets, and mandates that I enter my PIN every minute to access the phone.... a big pain. My biggest issue is when I am in the car, and trying to use my Bluetooth. When I press the button on my Bluetooth device, nothing happens and I see on my screen it needs me to enter in my PIN code....this defeats the whole purpose of "hands free". It is synced and I can answer calls, and send texts etc...when phone is unlocked....but it auto locks every minute!! and is a pain to use in the car, having to enter I the PIN every minute... Any advise I would greatly appreciate it!
