The primary reason why I rate the OnePlus so high. The main reason is its performance. Every component in the device works well and offers great experience. The speaker, as noted, is extremely loud for a phone. This makes watching YouTube videos fun on the OnePlus 3T. The phone has Qualcomm Snapdragon 821, which is a minor upgrade over the Snapdragon 820 inside the OnePlus 3, and 6GB RAM. The base variant still has the same 64GB internal storage, although this time around you can also spend Rs 5, 000 more and get the 128GB version too.
