I purchased IVooMi Me1 4G Mobile through online during Diwali offer at RS 3, 999. Picture Quality of the camera is not so good as it has only resolution of 1280*720 pixels only. The camera is also not well enough to take selfie pictures during day and night time. In specifications it is mentioned that supports OTG cable but when I used OTG Cable it does not show any option at all. So it is not a user friendly mobile. It comes with 3000 mah battery but it does not stands even for one day. After using the mobile for 2 months it started hanging and for every 1 hour I have to charge the mobile. Camera quality is worst as it has Primary and Secondary Camera with 5MP . It has Beauty mode, HDR mode and Panorama mode but quality is not so good. Battery life is not a long lasting one. Hence poor battery performance. So one of my kind advice is that not to buy this kind of mobiles through online and do not waste money.
