I remember I was reading somewhere that some Maguros have problems with connecting to network, I don't remember if it was about cellular or WiFi. So I thought maybe I was unlucky with my device, I got "lemon".
The worst is that when phone hangs on orange WiFi bars and can't connect to Google services, apps are running trying to connect and causing wake locks. Like just now in the morning I grabbed my wife's Maguro swiped down quick settings and I see both WiFi and mobile bars are orange. I had to toggle WiFi off and back on so it reconnects.
How can out be karnel problem if it is like this since I bought it in may last year (it was already one year old), on all ROMs and karnels I flashed, Google 4.2.2 and 4.3, custom rooms AOKP 4.2.2, SlimBean and SlimKat.
