Password Locking Issue

[hizduser]

I have password lock set up so the device will not activate (make calls, get on PIE) while taking it out of the case. I have it set to lock the phone for 0mins or whenever I turn off my phone. My issue is when viewing sprint tv, streaming music, or even doing a backup after several secs it locks up. Is there a way for it to recognize that you are viewing, streaming so it won't lock up? Thansk in advance!
