Phone is very nice, comfortable, and looks presentable, IPS screen HD resolution and medium qulity, 8MP camera -the level of 2011, no chips in the system and zero customization compared android.
hopefull apple will release and fix it soon.Some major advancement in this version includes a wuick reply from the natification badge itself, The kyeboard has quick or predictive typing function which is really smart, makes typingeasier and faster.
App-airdrop, bluetooth, facetime audio and video, using phone in landscape mode etc.
rest of the review is continued in comments.
