GPS suddenly stopped working?

I like to use Waze on my commutes to work. The other day, it started telling me "no GPS" and also telling me to try going outdoors. it worked fine on my way into work, but not on my way home. Restarting etc didn't change anything. GPS Toolkit also just spins endlessly. Google maps does not complain and seems to place me accurately. I live in a metropolitan residential area and this is the first time I've had an issue with the GPS; it has always worked fine along my route and even in my house.

I have other occasional quirks with the phone, esp where it just shuts itself down. I would consider factory reset if anyone knew if it would make a difference; I just don't want to go through that if it's pointless. Any thoughts?

(If reset is an option, can anyone give me hints or a link on how best to preserve current apps and settings etc? Things that I might not think about until it's too late).

Resetting has nothing to do with the GPS receiver, so I doubt that would fix it. (But you should keep a link to Backing up an Android Device just in case.)

Samsung used to have the same problem, and there was a fix for it, but it's Samsung-specific, so I doubt that it will work on your phone, but just in case:

Open the Phone, as if you were going to make a phone call and dial -
*#9090# -- Diagnostic Configuration (*#197328640# if that doesn't work)
Menu, select Key Input, enter Q
Menu, select Key Input, enter 0000
wait for the next menu. (It takes a while.)
UMTS->COMMON->NV REBUILD->NV REBUILD->SYSTEM->PROTOCOL->GPS->IMS
or, if you don't have UMTS:
UE SETTINGS & INFO->SETTING->SYSTEM->NV REBUILD->ALL

Restart the phone.

Thank you! And also for the backup information. I'll be doing the latter, hopefully this weekend since I'm beginning to think it may be time to replace my Nexus, esp since it's getting flaky in general, plus I like the idea of having newer versions of Android. And meanwhile, maybe someone will know a more Nexus specific fix.
