Hi , iam Sidhant im using One Plus 3T fron last 6 mounths and I am very impressed with the features it comes with android version 6.0.1 ( Mashmallow ) but u can upgrade it into android version 7.1.1 ( Nougat ) and its oviously a 4g device ( LTE ) , cpu is qual core and with 6gb ram thats mean your device is mever gonna hang or stuck in any situation , gaming experience is really very awesome
Camera
Camera quality is really good , its 16 mp and front with 2 mp , piture quality is great
Sensors
Fingerprint sensor is reallg accurate and fast prossing
Storage
Unfortunately there is no slot for any external sd card but due to internal storage 64 gd si sufficient for your data
IN SHORT ONE PLUS 3T IS REALLY COOL DEVICE , WHICH U MUST BUY THIS DEVICE , IF U WANT AMAZING FEATURES , AND PRICE IS ALSO REALLY GOOD _ 29999_ MUST USE ATLEAST ONCE
