Apple is one of the most popular brand and iphone 6s plus has got very feature like waterproof but this phone is not a waterproof or water resistant phone.
But after that also it may work in water and has a very easy to access and a design is very good in the terms of security iphone is one of the most secure phone and now ao many apps like xender is available for free for iphone also I like the most is sound and quik response of iphone.
