Hoping to see better support for Linux. The Fairphone team collaborated on the Ubuntu Touch port for the Fairphone 4, but didn’t do the same for the Fairphone 5. It would be great to see VoLTE on Linux on the Fairphone 6.

The FuriPhone FLX1 meets all of your requirements:

• It runs the Debian-based FuriOS, which is FOSS.
• Among phones with Linux (excluding Android) preloaded, its specifications are among the best available, including a camera with PDAF and OIS, a 120Hz screen, and a replaceable 5,000 mAh battery. It also supports 5G and VoLTE, and has IP68 water resistance.
• FuriOS includes Android app support via a fork of Waydroid.
• The phone and the Linux distro are actively maintained.
• Furi Labs is based in Hong Kong.
