Software update

[Moteet]

I have an Xperia XA1 updated from 40.0.A.6.145 to .165 to .175. I have noticed that the bluetooth does not detect another device. Also, in addition to this, my display size keeps on changing from my setting (largest) to the default but when I look at the setting it says "largest". Is there a problem with my Xperia or what? This is Addressed to the Sony Support group.

Enable developer options and manually set the dpi to the default scale. don't fiddle with the numbers, otherwise other apps start to display incorrectly because you need to do it as multiples

clear/reset network settings for the device, it will clear wifi and Bluetooth settings.. you'll find it in the "more..." menu for the wireless and networking section of main settings
