Pros :
Charging is very quick.
Processor used is- snapdragon 821 so performance of the phone is quite great and leaves no doubt about it.
Low light performance is very good.Rear Camera is 16 megapixel with great picture quality.
Antenna is both at the and bottom for broader connection range.
Fingerprint is very fast.
Cons :
While gaming phone gets a bit warm.
Amoled display is not as good as the ones on the samsung phones.
Sometimes it calls randomly from the contact when in the pocket, which is a software issue.
Even at this price you are not getting any memory slot.
My conclusion :
Overall one plus 3T is a great phone.For heavy users I will suggest this bomb phone.There are very few cons which arise rarely with some handsets but that is obvious with most of the android handsets in the market.There is no any big issue in one plus 3T.In my opinion if you have a budget of 30, 000 then this is an excellent phone based on its charging speed, performance and camera quality.Go for it.??
