Its been more than a year since I am using this phone. When I first saw it on amazon, I was in love with it. Its design is so good and I love the back cover, you dont even need to purchase a cover for your phone if you use your phone carefully. I loved the shelf feature they gave it inbuilt, its work like a magic for you. with good amount of ram( 4gb) and the latest processor, it was a flagship until oneplus lauched their another flagship phone oneplus3 and then oneplus3T but even after using this phone for one year I never faced any kind of issue related to phone hardware or software. It does got heat-up when you play for HD games for too long but I dont thing that is big issue because its not the only device we face this type of issue even samasung s7edge got heatup and iPhone too But in my opinion its worth than the money you are spending in this phone.
