@WorldTravelerAll7 My latest information is that there is no smartphone available with a fully functional main camera module running either Ubuntu Touch or postmarketOS.
Chipset manufacturers keep their camera drivers for themselves, and these are difficult to replicate. Additionally, the software solutions used to post-process data from multiple cameras are often proprietary too.
The only Linux phone with a fully working camera, as far as I know, is the new Jolla Phone https://commerce.jolla.com/products/jolla-phone-sep-ii-2026 . On other devices, only the selfie camera or secondary cameras work in the best case.
Also a drawback of Ubuntu Touch is its limited app support. Its app store https://open-store.io/ offers a small selection only, with many apps being unmaintained or buggy. Even browsing was such a pain on it that I installed Waydroid (the Android emulator) and used the browser from there. However, Waydroid drains the battery quickly...
