I have an old Huawei P10 Lite laying around, and I really like the form factor, and would like to use it as a secondary daily-driver, and to put on my bike for GPS and such.

But I don't trust this thing farther than I can throw it, and I would really like to install another OS on it, both for ease of mind, but also to hopefully get some more and better features.

Which options do I actually have? And are any of them worth it?
Alternative would of course be to just debloat it.
