This is like a therapy session for DNA owners, love this thread. I've had the.....
1. non focusing video recorder problem (not aware of a fix and hope an update is published soon).
2. recently the SIM card problem (seemingly easy fix with pop out and reinsert).
3. horrible Bluetooth quality on both headsets and hands-free link vehicle connection. Connections ocurr but voice quality is unusable for business conversations (not aware of a fix here either, so hopefully a software update will fix).
4. Odd camera problem has ocurred a few times where I was in camera app, hit the switch-app button (lower right hot key on DNA) in attempt to switch to another running app, and screen went blank. Couldn't shut down phone. Haptic buttons still functional but couldn't see screen. Left it alone and screen eventually came back up. Very odd.
5. And more of a complaint than a problem: the keyboard sucks imo. Back to swiftkey perhaps.
