First of all, thank you very much for your support here.
GPS Accuracy:
I think your last build was based in CM 12.1 from
jiayu.de
In the previous version from date 02/03/2016, at the end, the GPS accuracy was superb, unlike most other LL ROMs. Regretably in this new build, you present the same fault as others.
There is a loss of accuracy when increased the car speed. As you see in the attached capture it shows a maintained accuracy of more than 35 meters at 80km/h, issue that makes the GPS apps confuse the road/lane you're driving in.
Sensors:
The main issue I have is sensors related (Gyroscope, accelerometer, compass). Auto-rotation goes well but, in different apps, compass behaves erratically and in
Youtube's 360 videos there is a constant lateral movement, that makes it unviewable.
I have tried every kind of calibration possible, but makes no difference, and the lack of Enineer menu makes impossible any other kind of sensor adjustment.
Others:
Fast reboot in Advanced shutdown options hungs the device.
Without automatic brightness, if is selected the lower bright level it makes the display to blink.
15% battery bug (as many other ROMs)
No Engineer MTK Menu (as other CM based ROM)
