1. Won't wake up when pressing power. This has happened to me about 4 times, where I do a battery pull to fix the issue. It's happened twice with the standard battery, and twice with the extended battery. It's also frozen once while i was checking email. 2. 4GLTE/3G signals disappear. All I see is the bars on my screen, so I have no signal. I have to reboot in order to fix. 3. The camera is ridiculously slow. It may take 5 seconds or more after pressing the button for the camera to actually take. Ridiculous. Anyone else having the same or similar issues?
