Ubuntu touch had a dual boot installation option as given here https://wiki.ubuntu.com/Touch/DualBootInstallation#Installation

Shall we create a UBports dual boot option so that any android device can have a dual boot into UBports ubuntu phone, which will help more users to familiarize into ubuntu phone and also helps developers to use ubuntu from same android phone whichever they have.

The ubuntu installer apk is available here https://forum.xda-developers.com/attachment.php?attachmentid=2478802&d=1388212319
