7 months ago my cusion brother buy this mobile. Before the mobile was good in battery backup, great performace but there are some problems in this mobile.
First this mobile unable to find 4g singnal but in my friend's mobile singnal was full at same location. In this mobile sometimes 4g singnal come and after 5 seonds singnal was gone.
When we visit Samsung service center they told us that it was software problem. After 15 minutes they told that your problem was solved but when we arrive at home singnal problem come again in this mobile.
Really this is a very bad mobile by Samsung.
