I have a cheap Chinese made tablet from Dubai called the Crony Dubai (www.cronydubai.com). It has a micro B, mini HDMI and a USB labeled as "Host" as well as a micro SD slot. It came with a micro B to USB adapter in box, and its running Ice Cream Sandwich. Is there a way to load Ubuntu on it? Also the tablet is very buggy and crashes often, would that be due to the tablet or the OS?
I am assuming you are looking for something like Ubuntu for Android.
Canonical is also working on a Ubuntu for Phones (including tablets) which is going to be available for download anytime soon
- What hardware does Ubuntu Touch support?
- When is Ubuntu Phone/Touch coming to the U.S.?
its all work in progress though and it does not guarantee that it will work on your tablet.
Neither of those solutions are available to the public yet! and the first one is explicitly is for OEMs (thanks to Uri Herrera for pointing it out).
There are different ways of running Ubuntu on Android tablet. therefore you can go for the safest way:
Download Limbo PC Emulator
Create a virtual PC
Download Ubuntu minimal
Install Ubuntu minimal on the virtual machine with the command line interface. More here on Ubuntu help - Installation.
You should be up and running. This worked on my Ainol Novo 7 Crystal.
