I have been using this tablet since 6 months and observed the following things in the tablet.
I got the anniversary edition of the tablet and got a 8GB Sandisk memory card in the box absolutely for free.(I got this tablet in android 5.1 Lollipop. in the first month, it worked very smooth. but after the first month, it’s been hanging.
After a month, I noticed that the auto rotation feature is not working completely. I had to change the orientation of the tablet every time when I wanted to watch movies or live stream. I took it to the local Micromax service center. but they have degraded the operating system to android 4.4.2(KitKat). they told me that the tab was designed for Kitkat and there are some bugs in the lollipop version. but they failed to restore the auto rotation facility. I have noticed that when I got back home and I could not take back to the service center as I was busy with my examinations. so I had been using the tablet without the auto rotation facility.
Battery’s draining very fast if using internet.
Camera is O.K. couldn’t expect better than this in 6K range.
I am not able to use the tilt option in many games like temple run because there is no auto rotation facility.
The calling speaker is working with low volume so I had to use the loud speaker.
The earphones are not working properly since two months. so I have thrown them somewhere.
Charger and the USB are working pretty good.
