Screen glitches and my reading goes back to line 1.

Hi

I am having a small problem with my G3. Every so often (every other minute, maybe) the screen refreshes really quickly, kind of goes black for a fraction of a second and gets back to normal. When I am reading a book with kindle it does not affect my reading, but with some apps like The Economist, the article jumps to line 1 and I have to scroll down to get to the section I was reading.

This is a deal breaker for me, ever since I moved my Economist subscription from the Kindle store to a direct subscription with The Economist.

Does anyone have the same problem?

I am considering a reflash of the phone with CM13 or CM12 in order to see if the problem persists, but I am not convinced since at some point I might want to go back to the original FW and I have not figured out yet how to do that.

FTR, I have a OnePlus One and a Nexus5 but I rather use the G3 since I can have a 128GB SD card with all my music (subway commuting without signal is also a bummer in NYC).

Sound goes out on both my Nvidia Sheild Pros

Hello,

I was wondering if someone can help me out. On my Nvidia Sheild Pros if I let them sit and come back after about 10 min I no longer get any sound from my TV speakers. I have to power down the units in order for the sound to come back on. One unit is rooted on stock firmware 2.1 and the other unit is running Full Android OS Ver 2.1 .

Thank you.

Galaxy TAB screen goes black and wont come back on

My son's tab 3 screen will not awake and has to be reset to come back on. The screen comes back on fine when reset but if it left for a while it wont awake and I can hear the water sound the tab makes when trying to open the screen but it does not come on, has anyone any idea what could be the problem.
