Well after waiting for a long time the phone finally arrived at the market. I had Samsung S8 earlier.Due to some backdrops in camera feature, I bought this One Plus 5T because of its speedy OS, slim look, excellent battery life performance, but except the external sd card storage feature. Though it got 20 and 16 mp rear and front cameras but still the picture quality is not upto the mark compared to new redmi series phones. On an overall review this is a good and fast value for money phone. I am using it to the fulllest, still it does not got any type of lagging or slow down issues.
