OnePlusOne is an amazing phone. I am using from last 3 months up to now I didn’t get any problem. I have already upgraded to lollipop.
Literally the best phone within the price range and the storage of 64GB is too good. This phone enables fast charging i.e charges fast. This phone has great camera and need to set properly for close ups.Definitely, OnePlus One and you will not regret. If you are "brand" minded, go for HTC. If you are "performance" minded, go for OnePlus One.
