Hi Some time ago (2 weeks) - my tablet started to get freezes when WiFi was enabled (and connection established). Even on desktop - it was "thinking" for about 2-3 seconds each 15 ones. This stuttering makes watching movies etc - annoying. I've tried unlocking BL and then making root + then installing for example "greenify" which was doing great on my LG 4X HD. Nothing helped. Of course - factory reset was the first step. I'm out of ideas, I even tried to load "deoxed..." ROM - no change. I was on JB from start. I suppose it's hardware issue (network part), but maybe I do sth wrong. It was good for over a month after buying.. P.S. I guess - if I'd like to use the warranty - I should load back the original ROM (it started when it was in device), take off the Root and block bootloader?
