Coolpad pad note 3s is not a good phone, because its two bad features that are its battery back up and its processor only.
You cant use it continuosly on youtube for 3 hours.
and its brand new piece also become hangs whjile using.
And also according to its price, its camera is also not much metter and also its quality. So I suggest you to buy redmi 5A at place of it
at the same price.
