This is an excellent phone for the price. Very smooth ui and oxygen os will improve as things go ahead. We can expect updates as this company has only 3 products in its kitty. In terms of build quality there are very few phones that can match the looks at this price point. The snapdragon 801 is a former flagship processor which was used in past flagships and is a better bet than the SD 615 that populates this segment. The amoled screen is gorgeous and I must say better the ones on the oneplus 1 and 2. The adreno 330 is still competitive to push those pixels on this 5 inch screen. The only reason I have for cutting a star is the battery life which is fine but not overtly great And the body of the phone is a finger print magnet. A case on this phone is a must. Overall good job oneplus.
