Hi !
I come back with a fix for my "gps problem", after buy so many XZ1c with this problem, i try buy another one last week..... (i don't like the color "blue coral").. I just test GPStest and ... 40sat in view and fix without sim card in my house with 6or 7 sat, outside it fix with 20sats.. I'm so happy !!
So, u were right, it was hardware... But so many XZ1c have this problem. The XZ1c with problem come from Thailand (Rev 2 on the box), the XZ1c okay come from Malaysia ( Rev3).
So i will instal (Clads will instal ) twrp and i will stay with your rly great rom !
I pay you a juice 2 weeks ago, and will continue support you all the time you will support this great phone !
That's great news !
