After one year phone performance is not that good. Phone gets heated when I am playing games and unable to hear properly when other person is talking this happend when my phone got ios update.
If you start using internet battery gets down very fast in a day you have to charge for two times. You cannot have ringtone which you want only Apple default ringtones are available.
Both front cam and back cam compare to S7 edge, iPhone 6s camera is not that good. It is not dual sim. Recently I lost my ear phones and I thought to buy new original ear phones of apple but its too costlier.
If there are any updates to OS witout wifi OS will not get update. It cannot download through SIM internet.
