I recently upgraded my one plus 3 which I bought 5 months ago to oneplus 3T. First of all I suffered a great loss due to poor resale value of oneplus 3 and then I bought this mobile which was Rs 2000 more than the previous oneplus 3 ( Rs 29999.) I did not notice any change in this new model or any advantage for upgrading to this mobile. OnePlus has unnecessarily intoduced this model. The Ram is the same 6Gb, the processor is also almost the same. Only the front camera has improved from 8MP to 16MP.
One major problem that I face is of the software issue. The mobile hangs inspite of having 6GB ram. They are unable to develop a stable software for this mobile. Also OnePlus has not provided the video calling feature through carrier which is available in cheaper mobiles like redmi note 3.
It is a nice mobile but I would recommend NOT to upgrade their previous oneplus 3 to oneplus 3T.
