Advantage
It is really good 2g phone and camera quality is also clear.and good for low price phone.and oviously good about its battery life.review regarding on its price.
Disadvantage
Not smooth, hanging phone for its low ram situation, it is not supported hd video or movie,
Plz fixing the ram and hanging problem.
Overall it is good.because it is well maintiend of low price.only for that reason I can say it is good but not very good.
If it is fixed the hanging prblem then I think it is converted by a good phone
