First impressions are not the best, importing contacts from a Samsung brought all the names and numbers through but when receiving calls or messages their names don't show up. Found out they all had to have a country code in their numbers for it to come through. I have noticed when on a video call via messenger or duo, if you tilt the phone landscape it mutes the microphone? Not sure if thats a bug for my phone or its not optimised with those apps? Will look into this further before reaching out. It OS is a bit clunky and not intuitive. Gaming on the phone is great! so if thats all you are after then its great for gaming but I think if you want an all round phone for day to day use you might get a little annoyed with this one
