Buttons are duplicated in the navigation bar

[Corem]

Hi,

I ran into the following problem: all navigation buttons are duplicated on the screen (in portrait and landscape modes of the screen). This becomes a problem every time the screen is in landscape mode.
Maybe someone knows the solution to the problem?
Thank you in advance!

You seem to be using a custom launcher/theme and I guess it's the cause of this problem. Try to disable them and revert to the default Xperia Home launcher/theme and see if it's fixed.

You can also restart your phone into safe mode, this will disable all installed 3rd party apps. If the problem is resolved, then one of your installed apps is causing this issue and you have to figure out which one. Start by uninstalling those apps you installed recently.
