  1. Ota via wifi on sgh-m919.
    Everything runs great and some of the features are exactly what I was waiting for except for two things. Battery drains ways to fast, off of a full change I got 2 hours on stand by mode. Also the phone now over heats which has never happens before with my device. I really hope Samsung fixes the issue quick as you can go back to your previous is version. So if you update keep that in mind.
