My GPS began acting up on a trip from Nortwestern Ohio down to the OBX, North Carolina in which I used it for the entire drive and a few times while in NC also. It acted fine the whole way down there except for one time when it randomly lost the GPS signal and wouldn't obtain it again without a reboot. On the way home it did this same thing about 5 times. Ever since then, when I go to use my GPS (maps, or Navigation), the GPS will not even search for a signal. I leave my GPS off, so when I want to use it I turn it on and then go into Maps or Navigation... the little GPS icon doesn't even appear in the notification bar. Once I reboot the phone, it grabs a signal in seconds. I was hoping this would go away with the update, but I attempted it today and had the same issue... I contemplated sending the phone in for a replacement, but I'm afraid of what I'll get. Ive read many stories on here of people having issues with random reboots and what not. My phone has been 100% problem free until the GPS started acting up. It's not a huge deal, but I use my GPS a fair amount and don't really want to deal with this for 2 years. Anyone else having this problem or any suggestions on a work-around, or do you think I should return the device?
