@AppLee Hey, no problem, at least you didn't outright delete my question! :beaming_face_with_smiling_eyes: I understand a little bit more how UB works now, and I suppose it's a bit like Android in this regard, except it's not an OEM job. My phone has an SoC that's not completely one-of-a-kind, since other phones share it, but in the Leagoo inventory, it's an only child when it comes to CPUs, so I gather the manufacturer isn't too keen on investing time and dough in porting a more recent Android version to a phone that was released almost three years ago. I'll see the "Will you port my device?" part of the forum and see what they have to say. In the meantime, I'm going to familiarize myself a bit more with UB and how it works. Thanks for taking the time! Have a great one! (day, evening, don't know what timezone you're in)
