I looked for the process failure issue but it appears most people it has happened to have rooted their phones. Mine is stock.
Lately, Facebook is giving me a Connection Lost message A LOT. I am also finding my internet connection is not good/missing entirely at this time, despite still having the 4GLTE icon and all the bars up in the notifications bar.
In addition to that, I have noticed that my Bluetooth connection in the car is not staying on. If I reconnect, I will then get a process com.android.phone has stopped unexpectedly error.
I am not sure if all of these items are related. I'd rather not do a factory reset if I don't have to. Any other suggestions?
