It is a good phone it has good battery savings . It is having 6.0.1 kitkat android version I am using this from approximately 6 months and till now iam using this phone. The model number of this phone is sm-j210f but if you want to root this mobile you need to have one pc and one more problem is that you have only 8 gb memory which cannot be sufficient to us. We can edit the colours of the flash if we want to. Smart glow is a new and great edition in this phone in which we can be notified by light. Over all it is a good phone.
