I’m using m31s from last 10 days. I love it. First, its battery OMG! If I charge my phone at 10 AM today then it last tills 4 AM till tomorrow. Second, its display. It’s amazing. It’s colours. Third, Its camera. It’s cool. You can have great selfies and videos n photos. It’s colours are amazing Blue n Black. You must buy a case before buying phone. Coz the back is of plastic. Have a screen guard if you want long life of your phone’s display. Best for a non gamer. You can download normal games n play. It’ll not hang. No idea about PBUG, freefire etc.
