Open Beltrin Yuva+ tablet back cover case.

Hello,

Sorry for Device Selection, It was not listed.

I have a Beltrin Yuva+ tablet, borrowed from friend, and it seems that its battery is not working. (works only on Power Adapter).

I need to check the working of battery, but unfortunately I can’t figure out how to open the back cover as no notches can be seen. There are only two screws at bottom, even taking them out, still no luck.

I am attaching images for the same.
