[LG Optimus 4X HD] tnsantos:
I'm having lag issues whenever I change Internet connection. My phone lags like hell when I'm offline and connect to 3g or WiFi or if I change between 3g / WiFi. I'm using 20150101 build, but it is happening from a long time ago. I got the logcat, but I don't know if it is correct.
