I'm sorry to announce that I gave up on the Fairphone series and switched to a Google Phone (Pixel 4a) running CalyxOS.

Problems in fairy land

My fairphone2, even if it is less than two years old, is having major problems:

• from time to time, the screen flickers and loses "touch" until I squeeze it back together
• the camera similarly disconnects regularly
• even when it works, the camera is... pretty bad: low light is basically unusable, it's slow and grainy
• the battery can barely keep up for one day
• the cellular coverage is very poor, in Canada: I lose signal at the grocery store and in the middle of my house...

Some of those problems are known: the Fairphone 2 is old now. It was probably old even when I got it. But I can't help but feel a little sad to let it go: the entire point of that device was to make it easy to fix. But alas, because it's sold only in Europe, local stores don't carry replacement parts. To be fair, Fairphone did offer to fix the device, but with a 2 weeks turnaround, I had to get another phone anyways.

I did actually try to buy a fairphone3, from Clove. But they did some crazy validation routine. By email, they asked me to provide a photo copy of a driver's license and the credit card, arguing they need to do this to combat fraud. I found that totally unacceptable and asked them to cancel my order. And because I'm not sure the FP3 will fix the coverage issues, I decided to just give up on Fairphone until they officially ship to the Americas.

Do no evil, do not pass go, do not collect 200$

So I got a Google phone, specifically a Pixel 4a. It's a nice device, all small and shiny, but it's "plasticky" - I would have prefered metal, but it seems you need to pay much, much more to get that (in the Pixel 5).

In any case, it's certainly a better form factor than the Fairphone 2: even though the screen is bigger, the device itself is actually smaller and thinner, which feels great. The OLED screen is beautiful, awesome contrast and everything, and preliminary tests show that the camera is much better than the one on the Fairphone 2. (The be fair, again, that is another thing the FP3 improved significantly. And that is with the stock Camera app from CalyxOS/AOSP, so not as good as the Google Camera app, which does AI stuff.)

CalyxOS: success

The Pixel 4a not not supported by LineageOS: it seems every time I pick a device in that list, I manage to miss the right device by one (I bought a Samsung S9 before, which is also unsupported, even though the S8 is). But thankfully, it is supported by CalyxOS.

That install was a breeze: I was hesitant in playing again with installing a custom Android firmware on a phone after fighting with this quite a bit in the past (e.g. htc-one-s, lg-g3-d852). But it turns out their install instructions, mostly using a AOSP alliancedevice-flasher works absolutely great. It assumes you know about the commandline, and it does require to basically curl | sudo (because you need to download their binary and run it as root), but it Just. Works. It reminded me of how great it was to get the Fairphone with TWRP preinstalled...

Oh, and kudos to the people in #calyxos on Freenode: awesome tech support, super nice folks. An amazing improvement over the ambiance in #lineageos!

Migrating data

Unfortunately, migrating the data was the usual pain in the back. This should improve the next time I do this: CalyxOS ships with seedvault, a secure backup system for Android 10 (or 9?) and later which backs up everything (including settings!) with encryption. Apparently it works great, and CalyxOS is also working on a migration system to switch phones.

But, obviously, I couldn't use that on the Fairphone 2 running Android 7... So I had to, again, improvised. The first step was to install Syncthing, to have an easy way to copy data around. That's easily done through F-Droid, already bundled with CalyxOS (including the privileged extension!). Pair the devices and boom, a magic portal to copy stuff over.

The other early step I took was to copy apps over using the F-Droid "find nearby" functionality. It's a bit quirky, but really helps in copying a bunch of APKs over.

Then I setup a temporary keepassxc password vault on the Syncthing share so that I could easily copy-paste passwords into apps. I used to do this in a text file in Syncthing, but copy-pasting in the text file is much harder than in KeePassDX. (I just picked one, maybe KeePassDroid is better? I don't know.) Do keep a copy of the URL of the service to reduce typing as well.

Then the following apps required special tweaks:

• AntennaPod has an import/export feature: export on one end, into the Syncthing share, then import on the other. then go to the queue and select all episodes and download
• the Signal"chat backup"does copy the secret key around, so you don't get the "security number change" warning (even if it prompts you to re-register) - external devices need to be relinked though
• AnkiDroid, DSub, Nextcloud, and Wallabag required copy-pasting passwords

I tried to sync contacts with DAVx5 but that didn't work so well: the account was setup correctly, but contacts didn't show up. There's probably just this one thing I need to do to fix this, but since I don't really need sync'd contact, it was easier to export a VCF file to Syncthing and import again.

Known problems

One problem with CalyxOS I found is that the fragile little microg tweaks didn't seem to work well enough for Signal. That was unexpected so they encouraged me to file that as a bug.

The other "issue" is that the bootloader is locked, which makes it impossible to have "root" on the device. That's rather unfortunate: I often need root to debug things on Android. In particular, it made it difficult to restore data from OSMand (see below). But I guess that most things just work out of the box now, so I don't really need it and appreciate the extra security. Locking the bootloader means full cryptographic verification of the phone, so that's a good feature to have!

OSMand still doesn't have a good import/export story. I ended up sharing the Android/data/net.osmand.plus/files directory and importing waypoints, favorites and tracks by hand. Even though maps are actually in there, it's not possible for Syncthing to write directly to the same directory on the new phone, "thanks" to the new permission system in Android which forbids this kind of inter-app messing around.

Tracks are particularly a problem: my older OSMand setup had all those folders neatly sorting those tracks by month. This makes it really annoying to track every file manually and copy it over. I have mostly given up on that for now, unfortunately. And I'll still need to reconfigure profiles and maps and everything by hand. Sigh. I guess that's a good clearinghouse for my old tracks I never use...

Update: turns out setting storage to "shared" fixed the issue, see comments below!

Conclusion

Overall, CalyxOS seems like a good Android firmware. The install is smooth and the resulting install seems solid. The above problems are mostly annoyances and I'm very happy with the experience so far, although I've only been using it for a few hours so this is very preliminary.
