[Panzukk]

So, first, i'm sorry for posting in the wrong place, but in the help section ppl seems to be inactive

So, yesterday my note started to blinking in some parts of the screen, like a flickering or an interference and stopped to charge correctly. I only can charge it to 74% and it discharge very very fast, and i know that it seems to be a battery problem, but it could be a usb port problem? Cause, i've tested a lot of USB cables and in some positions them was charging, and in ohter, don't, and if i use it while charging, the phone discharge. Sorry for my bad english!

I'm facing same problem, and I have to leave my GN1 untouched until it charges completely.. I'm using USB B cable that looks to attach better to usb port. As GN1 is not my principal phone, I'm OK with this battery. I installed night owl nougat and it seems to be better charging GN1.
