Hi all. My GN is going through a rough patch and I can't nail down why. Basicly, to keep this brief, the rear/media speaker is buzzing, crackling, static(ish) when any sound is played through it. It sounds a little like electrical interference, most of the time a bzz and a crackle. I also noticed last night whilst watching a youtube video, that video playback freezed during a noticeable buzz from the speaker. Additionally, scrolling through the phone/browser seemed less responsive, slow and pausing for half a second on occasion. I'm unclear as to whether this is me looking for problems or an actual one, but I'm throwing it out there. I figure the phone is beginning to die on me but I really can't tell if this is a hardware fault or software. I contacted Samsung all I got was what seems to be a default reply; What is the easiest way of solving this? I've tried a factory reset before through the phone menu's and also reset through boot. Apparently I need to 'reflash' the software or software reset. Running 4.1.1. I don't mess with kernals. Installed Volume+ after sound issues to see if I can improve sound thru EQ, but have not increased volume. Any help would be awesome. Thanks.
