If you want to invest more than 50, 000 Rs then I phone 6s is the best mobile. Apple launched I phone 6 but I phone 6s is advanced of I phone 6. Best camera I ever seen in mobile phones. Design of I phone 6s is very nice and attractive.
If u want to buy I phone the I suggest you to buy I phone 6s golden because there is two colours available in I phone 6s but if you see its looks na then golden looks much better than silver. I phone 6s is really worth of money
