I'm running e/OS in my old Poco F3 right now. I switched from LineageOS because I though, e/OS would be easier to ungoogle. In the end, it just defaults to way more compromises than I would have made on LineageOS. Over all, it's actually just LineageOS with MicroG preinstalled, a really bad launcher, an ugly 2015-ish iPhone icon theme, and a few mediocre apps preinstalled, that use these 'Murena' services that claim to be an alternative to Google services, but they are neither more secure/foss nor reliable. Their appstore is rather Bad. Yes, it essentially combines something like APKMirror and F-Droid in one app, but it requests a Google account to access PlayStore Apps. Imho, LineageOS with MicroG, no GApps, F-Droid and APKMirror and a few foss apps is the better solution. I have my sync services selfhosted through a NAS and simply use WebDAV (backups), CardDAV and CalDAV. This was harder to set up in e/OS than in basic LineageOS, because e/OS is trying to push their own Murena services for that. And if I didn't have all of these selfhosted, I'd rather use Proton services instead of Murena. Over all, really sketchy. It's like a custom Rom that claims privacy but actually just wants you to möge to their own service.
