A name apple is brand
The apple realised iphone 6s after the success of 5 and 5s iphone 6s specification are same to iphone 6 but the different between 6 and 6s is the price
If u think to buy this phone I suggest you to do not bought this phone
In 15to 20k u can also bought any other company smart phone which provide you many more classification better than I phone 6s
If you want to buy a smart phone for your personality you can buy this mobile but this has much much more price
No doubt the camare future and ram are better than any other brand smart phone but the price is to dam high
