Wallpaper changing itself issue

[ViktorijaKra]

I had my Sony Xperia xz premium for 3 weeks now. And seems like after last update the lock screen wallpaper changing itself to default.

It happens once a day, usually during night, but now it happens during the day too. Background wallpaper not affected, only lock seen.

Nothing helped. Had to reset phone

After safe mode that was the next step.

I'm having your same issue kind of, when I set a theme if I change the home screen wallpaper it always changes my lock screen wallpaper as well even if I only requested to have the home screen wallpaper changed. I find this annoying and I think Sony is moving to slow to fix bugs. With Bluetooth tooth audio it's flawless if I'm streaming the audio no breaks not anything but if I streaming from the music app I have breaks in the audio and that is annoying too.

@santana;

I think when you want the lock screen wallpaper to look different from the home screen you have to select it separately, see if it changes after it.

My wife phone is doning the same thing. She accedentaly touched a gif in an email from Freedom and now it is the wall paper. She has reset the wallpaper again and again but everytime she goes back to the lock screen the unwanted wallpaper is back.
