Due to sale on amazon.in I bought iphone 5s in 17000 and I was very happy that now after so many years of wait I can use ios system, but I was wrong because this phone has some major issues which can tense or annoy you at different intervals.
The major issue is heating problem, whenever you charge it, it will heat like burning which can shock you.
The second main problem is that this contains ios 10 which is very heavy for 16gb variant and most of the space is covered by this update which also make your phone slow because this phone is works good on ios 7 and now ios 10 makes it little laggy and the main problem is that you have to update ios 10.
so I think these are some issues which makes me irritated and due to which I strongly recommend not to buy this phone at all.
