I usually do a lot of virtualization from both my main tower and my laptop, but I'm a bit curious to see if anyone is aware of a similar virtualization software to Oracle's Virtualbox for an android phone? I mean as much as I like to run an RDP passthrough to my main system and interface from there, the wireless service around my area is too spotty and unreliable to set out any real significant commands/services from. Plus, I happened to upgrade my Samsung J7 Star with a micro SD card for 128 GB, so virtualizing a lightweight windows/linux kerbal enclosure has at least a good 40-80 GB of wiggle room to experiment with.

So any ideas, suggestions or thoughts would be greatly appreciated thanks.

I can't imagine anyone undertaking that on Android. The problems are insuperable, the rewards are near zero.

As always, a Quick Search (tm) is the first step.

Doesn't look so good.

I like GNURoot Debian, Gimp* and ofcourse Turmux... all .apk
