One plus 3T is perfect choice if you need a good phone in 25 - 30, 000/- price range. I have purchased this phone for my brother and friends really , I have a very good experience with this phone. This phone contain very good hardware ( snapdragon 821 processor, 6 GB RAM, 64 GB internal memory, Adreno 530 GPU) . camera quality is very good but it needed some more battery otherwise the phone is very good.
Thanks!
