I am a user of this phone from the last 11 months. I bought it from amazon and after using it for 11 months I am going to share my experience e with you all.
1) There is no update of android Oreo or Nougat in one plus 2 which is a negative view here.
2)The back flip cover should be a bit more flexible.
3)the feature like 4GB of RAM and 64 GB of ROM is just amazing and this is the only feature I loved here after sound quality.
4)the sound quality is just amazing as io am able to hear all the beats neatly and clearly without any obstructive or irritative sound.
5)the style and design is good but if it would be in white color then it would look more cool.
6)lastly I would urge one plus to reduce the price a bit.
