CalyxOS (is coming to) is here for FP4!

I run the latest CalyxOS (without Gapps/microg; rooted via Magisk) since end of July and I’m more ore less fine with it. It is quite stable even still not official yet.

I have a couple of potentially beginners questions and some of them were already asked in the Calyx Matrix chat, but nobody reacted, so I give it another try here. Whoever have a suggestion, just reference the question number and answer ;-). We can also open another “Configuration Q&A CalyxOS - FP4 - Thread” if this is not he right place to asked these questions.

  1. Is there any documentation about the repos: “The Calyx Institute” and “CalyxOS Local Repo”? What are they used for? (they are both enabled in the pre-installed F-Droid → especially the local one confuses me)
  2. Is there a simple way to install a working Gcam (or a Port) on a Fairphone 4 with Calyx (Note: no GApps nor microg should not be installed → we discuss this already here and below)?
  3. Can I put shortcuts on the lockscreen? If yes, how? (e.g like a Camera App - I remember this from LineageOS I used on the FP2 before)
  4. I like to swype/glide type. There are OpenSource Keyboards which are on a good way (FlorisBoard, OpenBoard, AnySoftKeyboard) but still most of them are not fully functional in this special regards. So I always copied the libjni_latinimegoogle.so under Android 10 and 11 (to /system/lib) and after a reboot you can enable this functionality for ASOP keyboard. The problem now is, that I don’t find arm64 Android 12 Gapps to download, which consist of this library → https://opengapps.org/ . Is there anyone who successfully enabled it - if yes how?
  5. The Fairphone 4 does not have a notification LED, so I was wondering if there is a simple way to indicate, that there is a new notification (mostly interested about messages) when the screen is off? (e.g. blinking, glowing, would be already enough for me … back in the days there were apps like ACDisplay. Right now I use the app AlwaysOn but it is not updated since 2020 + not 100% satisfying (some apps are not discovered correctly etc.) I also know this thread, but nothing convinced me up to now. :man_shrugging:
  6. How about Magisk Updates. Is there anything which have to be kept in mind? We discussed Calyx OTA upates here: Howto install Calyx OS on FP4 - #15 by Smojo (which considers uninstall Magisk before etc. …), but how about an Magisk update itself? Just apply via Magisk App? Reflash the new version via fastboot? How big is the risk to do something wrong and potentially the OS will not start anymore.
