Take a look at Jolla and Sailfish OS.

FWIW, Jolla just announced a new phone: https://commerce.jolla.com/products/jolla-phone-preorder

It was discussed here when it was announced. I believe it was determined the hardware is an ultra-low-budget Aliexpress design that normally retails for ~$100 that they had custom built with a mic cutoff switch added to it (probably the cause of a large portion of the hardware price increase). I dont remember the specifics, but even thr most optimistic were pretty sure it won't get hardware vendor support for even a full year based on the specific processor it contains.

Can you please refer to the source of the Aliexpress design claim?

I looked through https://news.ycombinator.com/item?id=46162368 and there was nothing like that mentioned.

Replying to myself: Apparently I was mixing up the new Furilabs FLX1s and new Jolla phone. The FLX1s that's a major downgrade from the prior FLX1 and some people were reporting are based on a design that's really cheap on Aliexpress and using very old hardware but with a custom spin to add some physical switches to it.

The new Jolla actually does look really good compared to all the other avaiaobale Linix phone hardware options.

What phone with OLED, 12GB RAM, 256GB storage, and user replaceable battery is $100 on Aliexpress?

https://liberux.net/ looks promising as well.

WARNING: This is a Kickstarter device still, and needed funding to even create a proof of concept device last time it was discussed (extensively). It's a Flagship phone device and price, but with only the oldest of pans on how it's actually going to deliver some on of the promises.
