Samsung star advance is the worst of india because it has 512mb ram and the half od the ram take place by system apps so we can’t install any app rather than two to three apps .The worst thing in this phone is that it does not supports 3g it runs on 2g only.
The cheapest is the worst . the battery life of this phone is not so good but it does not drain fast .If you are planning to take this I would recommend you to not to take this phone take some other company phone
