Micromax bolt s301 is better not wasting money on this phone as Because the phone runs on single core processor which is the worst speacification of an phone if the processor is low quality then its useless to buy any phone the phone depends on the processor and ram these are the main things in a phone and in this phone only 1.0ghz single core processor and 512mb ram runs on Android kitkat means the phone is of no use for running a kitkat version in a phone minimum 1gb ram and minimum dual core processor and that also hang and this phone has half speacification to run kitkat version the phone camera is of no use the photo click buy this phone is very poor.
So I would say if any Android phone has single core processor it's better to avoid that because it's useless to buy this phone.
Thank you
