I bought this phone 6 months back, its a moderate device under 10k.there are many drawbacks in ths phone.
Its starting hanging frequently.
There is no battery backup. Camera quality is average. No inbuilt software for transferring file from mobile to sd card, one must download other apps like ES file browser to perform the task.
When playing big games the phone dosent function properly. It turns off after few minutes. There is a lot of heating issues.
No micromax service.
