Calling is something that works in e.g. Postmarket OS. The trickier parts are NFC payments, lack of apps. So it comes with huge drawbacks. Some apps can even require that your device is verified by google and you have no way of hijacking it.

Proprietary camera software is also a huge thing. Software can do so much thing and you pay for the software also, not just the hardware but you lose the software when you install something other than the factory default.

And battery optimization is very young in desktop grade linux OSes, you won't get that good battery life as with android.

For myself I don't consider NFC payments or the few apps that require device integrity auth. Not everyone falls into this category but a good percentage are. We need more modern open hardware. To the larger software point there is a lot of good Foss software out there even for phones. What we need is a open software center like a flathub that makes them easy to find and deploy.

NFC and battery life are absolutely huge concerns. Cell tower stuff isn’t great either but if you absolutely had to many of us can live without cellular and just do VOIP.

Apps aren’t that big an issue, waydroid is a thing and the appification of the internet is detrimental anyway. Do it in a browser.
