We are thrilled to announce a preview of a new feature for developers: Ubuntu on mobile devices can now run alongside Android on a single handset.
For developers only
Dual boot is not a feature suitable for regular users. It is recommended to be installed only by developers who are comfortable with flashing devices and with their partition layout. Dual boot rewrites the Android recovery partition and those installing it should be intimately familiar with re-flashing it in case something goes wrong.
Multiple Android flavours are supported (AOSP or stock, CyanogenMod) and installation of Ubuntu can be done for all versions available in the phablet-flash channels.
