Oneplus 1 in mu opinion is one of the best phone I have ever used as it cost about 22000 in which you r getting specs of phones which are priced at 35-40000, I genuinely think this phone is underpriced and before oneplus realizes this go get one for yourself.
Things I like about this phone is its battery is wuite impressive, processor is fast so u can play big games in this phone without any worry, good looking its the best part and many more.
Its also a strong phone as I have many times it has fallen from my hand and its still fine.
