Here is a blog post of the removal of the wireless charging compatible battery being put into the phone and then submerged in water. We think this is a pretty cool feature!

@furilabs - would it be possible to install vanilla mobian or alternatively can plasma mobile be installed on the phone with the stock OS?
@jamesjones We currently do not support any system other than FuriOS. Other operating systems might very well be possible, but our team is most focused on what works best and is designed for our hardware.
From our knowledge, there is a branch of plasma mobile that can work on the device, but we have not tested it, so we cannot confirm
Feel free to try and inform the community!
