I an usinh iphone from last 3 years not just iphone 6.
iphone 5, 5s I also used
while I purchase this phone by that time this phone was awesome but now this phone gets slow down just because of the new latest updates
dont buy this phone in 2018 because its too old now also ill recommend you to purchase latest one this one will comes with some attractive prices but seriosly speaking it is not worth right now !
