[Nexus 7 (2013) Q&A] TB5:
Okay, first off, I don't know if this malware related or not. More on that later. I DO know that I've had my nexus for a few years now, and it's been great til a week or two ago.

The latest, and most urgent, problem is that it randomly stopped charging. I was plugged in, playing a graphic-intese game, and got a pop-up warning me that I was at 15% life. The charger is in an extension cord. Sometimes it gets partiality unplugged. So I jostled that. Made sure everything was plugged in, and kept playing. At 7% I got another message. I double checked everything, and noticed that the circle moving around the power % would sometimes make a cycle or two before giving up. (It's not even doing that anymore though.)

I've checked the socket, power cord, charger, and cable. All work with other devices. I used another charger, in another socket, with the Nexus. No response. I've also tried rebooting in safe mode, and following this guide . Those didn't work either. Now, I'm at 6% and scared to turn it on, without having a specific plan.

This is a long post, so I'm going to give a TL;DR here. Other **** has recently happened. It might be related. It might not be. Point is, if I have any hope of fixing those issues, I need to first fix this.

Now, why this might be malware-related. A week, or so ago, started having issues. "Shockingly enough", they began right after following some shady links on file locker sites. I was trying to find an iso for an old pc game, and figured that it'd be safer on my android. I still don't know if that was the source, or coincidence, but if this was happening on a PC, that would be prime suspect #1.

Anywho, I think it was the next day, my screen stopped responding to the magnet in my case. This had happened long ago, when I first flashed CM. I didn't want to have to spend a day or two backing everything up, and reflash, so I installed Magnet Unlocker. This has been a sufficient temporary fix, and I figured I could live with it.

Either later that day, or the next (I work a swing shift. Days melt together.) I used the LastPass browser to go to XDA, and got a bunch of random redirects. I started googling for clues, and ran every malware scan under the sun. They all came back clean. I did find a few forums that spoke of a virus around January that effected Chrome. It acted in the same way, and would redirect you if you tried to visit a number of android websites. I rarely use the LastPass browser, so I don't know when this might have began. I believe it is Chrome-based though. I tried to follow the guides posted to fix the issue, but LastPass didn't have the tainted file that was mentioned.

Several days passed, and I searched for solutions, but nothing debilitating happened. Then, last night, the screen started flickering. Or rather, the menu bar the bottom of the screen did. This also caused the game I was playing (Marvel's Future Fight) to lag, and crash. It was late, so I just said **** it, and went to sleep. I haven't seen the flicker since, but I also haven't used my tablet a great deal in between incidents.

I'm rooted, am using a flo Nexus 7, and on CM12. If anyone can point me in best direction, I'm at a loss as to what to do here.
