Late response here: I just joined forum tonight. I use Ting in US, and use GSM SIM for my Nexus 5 running Ubuntu Touch. It's been fine so far.

Hello - new user here, I bought a Nexus 5 specifically for Ubuntu Touch to (hopefully) rid myself of the Android | IOS duopoly. Profuse thank you to the UBPorts community! Aside from a couple of quirks like above, I love it (fwiw)!

If this issue is addressed elsewhere in another thread please kindly point me to it after appropriately flogging me (but I didn't find it).

When I start navigation using either Unav or Pure Maps (both affected): at some point, the progress of current location on the map hangs (Interestingly in the case of Unav, it continued to issue voice directives for waypoints). If it matters, I'm not sure to be honest which Android version I started with when I received phone, as I simply unboxed it, powered it, and proceeded to install Touch. What can I do to remedy the navigation apps stalling/hanging, if there is in fact a current remedy path?
