Using Iphone 6S black color with 32gb memory form last two months.
Never find any hangs or any slow down issues when using multiple apps on iphone 6s.
Both the front and rear camera works well.
Able to play all the video and audio clips smoothly without any issue.
It looks stylish, slime and it is easy to hold in hands
Connectivity works well either 4g or 3g or 2g or even with wifi.
Touch screen is absolutely the best feature in iphone 6s in-fact I had never seen this kind screen on any other phone.
Battery back up is also fine.
Nothing much negatives to mention about iphone 6s expect price is bit expensive
