I have Volla X23 with Android 15.0, latest OS upgrade is installed

@sermountain I get the same error on my volla tablet

My volla phone quintist has ubuntu touch as the only os
I asked volla about this error they said its a bug and is working on fixing it

I like ubuntu touch more then volla os so I might install ubuntu touch as only is on my tablet

My quintist I bought with ubuntu touch

@sermountain Dualboot with UT is not supported by UBports but directly from Volla. You may get some help here of other users, but not very likely since Volla support does not participate in this forum.
