I am using this Mobile One Plus 2 from last 2 years now and frankly speaking not a single flaw I have noticed till date. Look at the feature 64 GB internal memory 4 GB RAM 13 MP Camera and I must say being a photographer by hobby I often switch from my DSLR to One Plus Camera coz its awesome. Speaking about the battery initially I was scared as this phone has non detachable battery like Iphones but the 3500Mah battery backup is just what I needed. Its sleek good grip can operate with single hand. Good graphics. Awesome sound quality. Fast charger and tangle free flat data cable. Just live it still no competitor. Only flaws are no external memory slot but dual sim. Sleek body but bit heavy. Has finger print lock-unlock.
