One plus 2 which is a predecessor of One plus one which was a huge hit back in 2014. One plus two on the other hand is beast on papers but is not a good performer in hands. Even with 4GB ram and housing a Snapdragon 810 chipset, the phone is still is under performer in terms of battery and heat issues.
I bought the mobile in Amazon with out an invite. In the initial days the phone did not exhibit heat issues but later when I was playing normal games like Second earth, Candy crush etc I felt the mobile was exhibiting heat a lot and to be frank it was like a mobile IRON BOX.
The battery was a huge disappointment even with 3300 mah battery I had to charge my mobile twice a day where I normally log in facebook, watch videos for half hour a day and play normal games.
The good part is the finger print scanner which was very responsive and I was also satisfied with the camera performance. The call quality was satisfactory
Overall I was disappointed with the mobile and asked Amazon for refund and the company did refund my money as promised.
