Here is to inform you that on samsung's budget device Galaxy M21 had got a recent sofware update of one Ui core 2.5 version with some improvements in camera performance....So, the camera performance and the picture quality is quiet good than earlier, but the issue is the default camera application is now lagging a little bit while the other samsung default applications are running in the same time are quiet good ......so I think samsung must have to check out this problem and solve it in the next security update, otherwise all the features in galaxy m21 are running smoothly......
