>Software updates are a must-have
Why? Your phone has 3 main functions:
>Communication (SMS, GSM calls, VoIP, email)
Communication standards have remained identical for the last 10+ years. The only thing that changed with 3G/4G/5G was bandwidth upgrades. It's functionally complete.
>Web browsing
Browsers get updated outside of OS. Also functionally complete for simple pages, anything else shouldn't be browsed on mobile anyway.
>Multimedia (music, video, YT etc)
Functionally complete.
All main usecases of a phone are complete. There is nothing more to update. Treat it less like "abandoned" and more like "done". Finished. Complete. Implemented.
>inb4 security/privacy/whatever
GrapheneOS. It's also functionally complete and rarely adds new features, but has much better security than stock Android/AOSP and ships updates regularly. It's even better because you get a blank slate instead of shitty jewgle SaaS apps.
>inb4 GrapheneOS will drop support too
LineageOS. That will have support for literally the next 20+ years if not more.
Install FDroid, then from there: Fossify phone, messages, contacts, clock. Telegram FOSS, Signal, Conversations (XMPP), K-9 mail are also there. Use Vanadium for web, Tubular for YouTube. Search up your favorite offline mp3 music player and install it. Fossify provides one as well, in general any "core" phone app Fossify should be your goto.
And then... you are done. That's it. No more features, no more updates. You have every feature you need. You're simply addicted to updates and have withdrawals because jewgle brainwashed you into thinking you need theirs, and theirs only. You don't.
