I watch Netflix frequently on the Exhibit II 4G, using 4G data and Wifi. In either case, when I'm on the treadmill after a while it'll freeze up, act like it's rebooting (but doesn't go through the splash screens), and when it comes back the screen has a blue tint and flickering and is unwatchable. After reboot and in the Home screen, the blue is not there but can clearly see some flickering, maybe in the backlight lamp. This happened 2 or 3 times over a few days. Prior to using on the treadmill, it has never happened. Shutting the phone off then back on still shows flickering. In Netflix it's still tinted blue. At first I thought it was the vibration from the treadmill, then it happened on an elliptical, so I thought maybe it's the elctronic interference from the exercise equipment control panel where I put the phone. Then it happened in a stationary car once (but just once). I'm wonder if anyone has encountered this. It's not rooted (haven't figured out how). Is it possible it's from heat? But why not on other occasions when it's not on an exercise machine??
