There is so much network issue in Galaxy M21. For a 50 MBPS Wi-Fi it catches only 36 MBPS which is not enough. Please improve this is really irritating to Samsung users. The camera is also not proper in zooming, the phone charging is very slow why Samsung why. The phone has why Samsung why. If the problem is which you also then please tweet on Samsung #why Samsung why problems on M21

there is problem with some other M21 users like me. I think you would be living in metropolitan city so you do not have problem
