Hello,
since few moths ago all worked fine and I didn't change anything. Now, there are few apps including Google Maps and OLX (polish auction apk) whichc have issues with location. I run JB 4.1.2 on my device and I don't wanna upgrade or something, alredy tried that and it sucks, and as I said all worked fine till now.
THere is an icon in Google maps similar to GPS icon, and when you tap it it makes Maps go home, means to location when you cuurently are in. Now when I ap it it says "acquiring current location" or whatever it is in english ( because i use polish language) and after a while it gives "current location temporarily unavailable". When I go to settings, location etc. and i check anything it crash and kicks me out to desktop. Since i remeber, from time it worked, I did nothng to my system. It came out suddenly without a reason. When i open a browser with Google on startup, it can set current location because i have my city name on the bottom of the screen. Other stuff works too, only Maps suck and this auction apk because when i set manually location it works, but when i tap "last location", which is the same, it says "location unavailable".
