N900A will not keep time
The ATT N2 seems to have had the same problem for some... My N3 will not keep time. It doesn't drift when active, but when it sleeps it loses enormous amounts of time. This morning the clock was more than 3 hours late. I did a full reset and it didn't make a difference. Network/time zone sync makes no difference. Setting it manually it still loses time when asleep. Initially the time is right. Only way I can resync is by enabling and disabling airplane mode. It's ONLY losing time when asleep, confirmed with TimeSync. I don't have root so TimeSync can't put a bandaid over this problem with auto-sync.
It's as if it has the equivalent of a dead CMOS battery, but I know modern mobiles don't have independent batteries for time. Surely it can't be specific to my hardware.
Edit: I exchanged it. Absolutely bizarre that this would be a hardware-related problem, but evidently it was.
