I’m using I phone 6s since 8 months, and I’m facing some lag init while I’m using some Norman work, finger print is good and fast, camera quality are good for both cameras it work fast. I’m not facing any kind of heat problem. Phone is most kind User friendly. Mobile looks so good in hand. It’s look good from front and back. Battery work normal. It gives you a day backup is you is normally. Phone is little bit costly, you have several other options in it’s range so go for it. This phone is not for hard Users
