Micromax E313 is good phone inblow budget smartphone. Camera quality of this phone is also good. I also used this smart phone and my experience is very good. There is no heat problame in this smart phone.
Best part of this phone is this smartphone is not hang when we used lot of application.
I extremly suggest you to use this smart phone if you have low budget and not interested in useing 4G phone.
The drawback of this phome is there screen protection is not good and this is 3G phone. So jio lover can not use this phone.
Overall this is good phone in their budget.
