My friend has a Galaxy SIII and since he bought it it's been doing very strange things - at points where people all around him have excellent reception his phone will drop to zero bars and stop communicating. His phone has also done very odd things like spontaneously rebooting itself and/or just shutting down with pretty decent battery (above 60%).
The weird thing is the "zero bars within visual distance of a nearby Sprint tower while others get full signal reception."
I was walking right next to him in a store where I was getting around -59 dBm reception on my Sprint phone and his phone was showing zero bars but about 75% battery.
I took a look at his settings and it seemed normal enough - there were no firmware upgrades to be had and it seemed normal enough except for the odd behavior. He hasn't dropped it - it still looks new and he only got it in October.
Well, he took the thing to our local Sprint service center and when the tech saw it he kind of got a little disgusted look and took it in the back room and apparently totally wiped the phone and pushed the latest firmware on it and restored all his data.
Now it's been working pretty well. Has anyone seen this with the SIII phone behaving erratically or just a particular firmware revision be fairly erratic?
