Also known as
This hardware is sold under many guises. If it is claimed to be an A13 tablet but with a 4.2.2 android, then chances are that it is an A23 one instead.
Examples:
- P100
- A20h
- Eken A70H
- Eken X73
These are frequently mentioned:
- A20x
- A70x
- Q88 Pro
But likely they are A70x. Note the micro HDMI port between the micro and normal USB ports on the A70x
