I am using this phone for atleast 2 years , and I am facing lots of problem in it .
First of all I would feel you why I bought it.
I bought it because at that time it was the latest phone and it has 2 GB RAM so I thought that it would never hang or get stick in between .
But as the time passes the phone started showing its colours . It start to hang . Get stop in between process etc.
Now talking about ROM it has only 8 GB so it only provode 4 GB for us to use . And if you start doing update of all apps than the memory storage will be full
So you must have external storage for this phone
Secondly it doesnt provide update at all in the starting its come with lollipop and the second update was of marshmallow . Now there is no update .
Camara is also Okk it can not compite it with others
Sound reception is good
Display is also good
I would not recommend this
