I am using coolpad note 3 lite from more than two months, its fingerprint sencer is very good.
And its 13mp rear camera is not that much good in low light conditions, its front 5mp camera is very good compare to other 5mp brands camera, its 3gb ram is awesome, but coolpad is not giving marshmallow update to coolpad note 3 lite they are saying that they are working on it but they are giving the exact date of OTA update, android 7 also coming but they are still at lollipop.
