My brother has been using this phone for over a year and now I will share my reviews regarding iphone 6.
when this phone was launched it was loaded with great features but now in 2018 all those features are available in android phones and also at cheaper rate.
I have used this phone and it lags on ios11.
it has a decent rear camera but the front camera is of 1.2MP which is not good enough and many other better options are available in the market.
the design and the look of the phone is outdated and is pretty common.
iphones have storage issues as they dont have expandable memory.
so keep these things in mind if you ate looking for buying a new one
