I have the latest version updated on my XA1 Ultra. But I have found that my compass is very incinerate while using in Google map and other navigation map. I tried to reset my phone without installing any apps, go into service test , compass calibration. But Google map still showing compass accuracy in 'low'. And the compass sometimes turning around messy while navigation. I knew someone has posted this issue with XA1 but not XA1 Ultra without any solutions yet.
