Hello,
Noticed a problem on my XZs, when changing from sound mode to vibration mode, it changes and keeps for a while, but after some time and unlocking phone, the screen flashes/resets for a second, and the sound settings changes from vibration mode, back to sound mode, other things stay same, for example opened programs and everything else. just the sound options changes.
Anyone experienced something like this, or has an idea, why this problem may occur ?
