Micromax fun book infinity is one of the worst product I have used as a tablet. When you look at the price of only 4500 you won’t think of very best of the quality but at some degree anyone would want a decent tablet that would atleast get the work done properly.
The tab looks very good on paper in terms of expandability, battery and screen size and I guess that is the only reason why anyone would consider buying this tablet as of you start using the tab its just useless.
The screen quality is very bad at first. You will watch something HD it will still pixelate most of the detail and if you watch a whole HD movie it will hang thanks to only 512 mb of ram. The next thing that I personally very much hated that. If you are typing it would stop responding and if by mistake you press backspace it will get hanged and will be stuck on the back button and erase all the text and you can imagine what anyone would feel. Talking about battery life it was ok unless it just randomly turning on and of again for no apparent reason.
And never think about gaming for sure you will be just thankful if it can even multitask as most of the time the phone just restarts app again. I was so frustrated that I just sold it as you cannot just use this tablet and get frustrated and that is not the reason why I will buy a tablet.
