I use Jellyfin to host my music, and Finamp on my phone to browse and listen to it. Finamp supports downloads as well, so you can listen to your music offline and away from home. Pair that with a self-hosted VPN to access Jellyfin away from home and you’ve got most of your needs covered!

GrapheneOS kills support when Google kills security updates, I believe. Source: my Pixel 4a came out in 2020, and Graphene already strongly recommends against using it and dropped updates entirely a few months ago.

Lineage and Pixel Experience ROMs are better at long-term support. But any custom ROM on older non-officially-supported phones is vulnerable to firmware exploits, since those fixes are typically distributed as binaries by the hardware manufacturer (Qualcomm etc). So I understand why Graphene drops support so quick, since they want all Graphene users to benefit from strong security practices.

Longevity is worse than non-folding phones, simply because the hinge and folding screen are wear parts.

Camera is worse, because there’s less z-distance for lens depth. If they push it with a bigger camera bump, you wind up with a maximum thickness of easily over 15mm very quickly, even if the rest of the phone is thin, that hurts.

Battery life is worse, because two separate batteries with puncture protection, folding screen, digitizer, etc in between are heavier and less power-dense than a single large battery.

And the price is higher because there’s more screen, more batteries, more materials, and more R&D to pay back in the hinge and fold mech.

The Z flip is the most tempting to me simply because the height and width are far more attractive than current monster-sized phones. But it’s disingenuous to pretend the plastic inner screen (yes, that’s literally what that top layer is, not glass), the cost, the inferior battery, and the inferior camera aren’t serious compromises.

And all for what? So I can have a giant inner screen? I think my (smaller than any modern phone) phone is already too large, too addicting, and too tough to use with one hand. For serious tasks and videos I use my laptop.

I believe it is awesome for you. But there are downsides.

Same. I should really learn to use a simpler one, but I love this model and it still seems rock-solid to me after years of use. The best part is not ending up with sharp, dangerous edges on the lid!
