Hii guys, My brother has bought mi 3s prime 3 months ago.I am sharing my experience about that smartphone.In starting It works good. But after 1 month it’s fingerprint sensor stops working and camera app doesn’t open.When I put earphone in it then the phone opens google voice search in it and other apps.I took it to the mi care. They updeted their software and for one month it works smoothly, and then its speaker implode.Now it gives a bad sound.A also sometime when it is on charging it gives a little electric shock.It is not a safe smartphone. So for me it was not a good phone. it has nice features but it’s hardware is very bad.
