If you can live without all the apps that only exist on Android or iOS, then a non-Android-non-iOS phone is a great choice. But it only takes one of those apps to be essential to you and your non-Android-non-iOS phone suddenly becomes a miserable experience on a daily basis.

You say you don't need a banking app. That's great.

Me, I currently live in a country where banks are entrusted by the government to handle secure authentication online. If you can't use the mobile banking app, you can't interact with social services, the local equivalent of the DMV, healthcare system, police... And you can't book a train ticket, change the trash collection schedule, check if your parcel has arrived at the post office... Everything is online here, and without the banking app, your life becomes very very difficult. Not impossible, but not a pleasant experience.

And my company requires me to use the Teams app. In fairness, if I can't use it on my phone or I refuse to install it on my phone on principles, they will readily provide me with a work phone - and a pretty nice one too. But that means I'll have to carry two phones and, well... I just don't want to do that.

So if a Linux phone works for you, more power to you. It's just that you're a minority of extremely lucky people for whom this arrangement is at all workable.

Yes, an inept user can install it. I know because I am a fairly inept user 🙂

The key to a successful deGoogled OS installation is picking the most compatible phone possible for the AOSP flavor you want to run. If the phone is well supported and everything is reported to work, you're unlikely to run into issues.

I chose a Fairphone 4 to run CalyxOS. Or rather, it went the other way in my case: CalyxOS was kind of imposed on me because my requirements for the phone was first and foremost not be Google Pixel phone (i.e. GrapheneOS was not an option) and good repairability second. CalyxOS is the only deGoogled AOSP distribution that runs on the Fairphone.

If you look at the instructions to install CalyxOS on the Fairphone 4, it's nicely detailed and really simple. It went without a hitch for me. You can also install it on the Fairphone 5 and it looks simple enough too, but I haven't tried it myself.

As to why I like it:

• It emphasizes privacy over security (like GrapheneOS). Yeah it might not be quite as secure as GrapheneOS, but it's more practical.

• Enable MicroG and you basically have a normally-working phone. Yes, you still hit the Google server and that's not great. But sadly that's part of the compromises you have to make with your principles if you want to have a somewhat normal digital life in this day and age.

• System-level integration with F-Droid and Aurora. The GrapheneOS people think it's a liability. I think it's a plus.

• Comes with a work profile manager that works fine out of the box. You don't need to install a third party manager like Shelter.

• I know I'm gonna be shouted at for saying this, but... The Calyx Institute is always a little behind with Android updates unless they're critical, and I find that to be a plus regardless of the OS you use - desktop or mobile: when your OS pulls updates as soon as they come out, it pulls screw-ups as soon as they come out too. CalyxOS' delay in pushing updates means you let others play guinea pigs for you, and you only get updates after they've been thoroughly tested by a large number of users.

• CalyxOS comes preinstalled with a nice set of apps. I especially like the Datura firewall: it lets you use sketchy app and deny them access to the internet. For instance, I use it to configure my TP-Link smartplugs with the TP-Link Tapo app without letting this hateful turd of a spyware app call the mothership. I don't quite like how the SeedVault backup software follows the Android security model, because it prevents you from doing a true, full backup. But it does backups nicely and securely and that's better than nothing. And the Calyx institute offers a free VPN: I only tried it once and it was kind of slow, but hey... it's free.

• Like I said, it runs on a non-Google phone. I hate Google with a passion and there was no way I was going to give them money to get a Pixel phone for the privilege of not being subjected to the Google surveillance. So most other deGoogled OSes weren't even an option for me.

Not the original commenter, but just a +1 for Calyx from me.

It is very easy to install and it clears away a lot of low level Google tracking within the OS itself. It also comes with some nice additions like a firewall system for blocking internet access for that one google app (like keyboard or camera) you still need for whatever reason. Can't recommend it enough.
