After updating to a different Jelly Bean ROM on my Galaxy Nexus, I found out that GPS wasn’t quite working as well as the developer advertised. Just yesterday my phone would not get a GPS lock, which was quite inconvenient as I was partially relying on my Galaxy Nexus to navigate at the time. Initially, I attributed it to a problem with my particular ROM, but it turns out that this is an issue that many Galaxy Nexus users are experiencing with ROMs based on the Android 4.1.1 OTA update.
If you have a Galaxy Nexus with Jelly Bean, I would suggest checking whether your GPS works so that you don’t end up in a situation where you need your phone to navigate. You can do this with a GPS tester app, or just look for the telltale “Searching for GPS” banner in the notification area when using apps like Google Maps or Places. It should be fairly obvious that your GPS isn’t working, because the phone won’t be able to get a lock on your location.
Luckily, the fix for this problem is quite easy. In the Settings menu under Location services, there is a checkbox for “Google’s location service.” According to various reports, simply unchecking and rechecking the box will fix any GPS issues that may be present. It probably wouldn’t hurt to reboot the phone before checking the box again, but it shouldn’t be necessary. I’m not sure exactly why this works, but as far as I can tell it seems to have fixed the GSP issues I have been experiencing with my Nexus. Speculation is that there is a problem with Google’s location servers, and resetting the phone sorts it out. Whatever the cause is, it is certainly helpful to know that there is a quick fix for Galaxy Nexus GPS issues, and it isn’t a permanent problem or major Jelly Bean flaw.
