My Firephone Hangs then Reboots Often when using Mobile Network

Hi guys, I just recently bought a new FirePhone now on CM11 however what I noticed is that it keeps on rebooting like almost every time an application uses the internet connected to mobile network.

Has anyone experienced similar case as this? I tried not to use mobile internet and instead used Wifi and internet connection worked fine and there were no reboots.

I am using CM11 release of 09/15/2015. I followed well the steps on installation. Performed clean install and even installed GApps pico but still same outcome.

I hope someone can share what was done to prevent the sudden reboots when accessing mobile internet.

Why does Google Maps lose calibration so often?

I'm not sure what it is, but for the last few years, all the Samsung phones I've had have always lost calibration in Google maps after every few uses. That's disgustingly annoying. Does anyone know why this happens and how to fix it permanently? Please don't suggest installing another calibration tool to fix this issue. I'm looking for a real solution.
