And the troubles you revealed, this is not a good device. Get your money back as it's clearly defective. I hope you found the XDA forums and asked if there is a way to fix it.
I have a 7 " Zeki tablet running ics. It does not get Google play. It has a front facing camera only. TB782B http://www.zekitablet.com/zeki-support.html
I am trying to find a bar code scanner app so I can do comparison shopping.
I have been in touch with support and they recommended a factory reset and downloading from opera, amazon, getjar.
Did all . I currently have scan life app BUT, it says camera in use by another program and will not work. Have made sure no other apps are working.
This is a very inexpensive tablet and it has done everything else I need, but am getting a bit frustrated with this one thing.
TY for any suggestions, even if someone can tell me that these type of apps won't work with front facing only cameras.
