I just got this mobile 2months ago.For the first itself it is working slow and dint even playing much games in it, of course I’m using internet. I’ll get irritated when mobile stop functioning suddenly when I have important work with it. And about battery I need to keep charging twice a day , very bad battery .when I work on some other app it brings me other app automatically. Really one should have lot of patience to use this kind of mobile in many ads they highlighting about front camera but all photos during night which I’m taking are Shaded.Finally person who is using this mobile vivo y53 shall advised to visit hospital and check his BP
