Compass calibration issues Oreo

[Zedalon]

Hi ever since I have had my XA1 ultra I have never been able to get the compass in Google maps or the Sony test menu (the one accessed by the *# code to calibrate it always says low accuracy. At first I thought it maybe I wasn't doing something right so I called 02 and they suggested I go to there shop and see a guru he tried number of different settings but nothing worked 😕 so he said it would need to be send off for repair which being the phone is only 3 months old seemed a bit of a kick in the teeth. Then I thought about for a while and wondered if it may have something to do with the Oreo update,,it just so happened that my wife and my 2 friend have the XA1 and when I checked theres had the same problem and none of the 3 XA1s would calibrate.oh and in both the Sony test menu and the support tests the accelerometer worked. Has anybody else had this problem since the Oreo update?

On my XA1 dual (with Oreo update) some apps that use compass, know not to work correctly from time to time. But after vigorous calibration in service menu (*#*#7378423#*#* / service tests /compass) all works fine. Also, environment (buildings, EM devices etc.) know to make problems. Try calibration in open area.
