I'm having serious problems with one of the screens blacking out at random since the April update.
Sometimes it's like the Duo was folded over into a phone mode (with one of the screens displaying "double tap" prompt), but most of the time one of the screens just turns off.
I've been using three Duo since day 1 and honestly this has been the worst experience since G1, the first Android phone. Coming to Duo from Galaxy one can really appreciate how intuitive One UI is. I was hoping for some improvement over time but all I get is disappointment. The camera experience is terrible, the launcher is crippled. And the lack of communication from MS is just a cherry on top.
I was hoping that with April update there will be some progress but it seems to be getting worse with every update.
