After todays update magisk is gone. I have the app and zip-file from magisk.me. The app showed me that it is not installed, Had to flash the zip-file again. Magisk is working again. But I don’t know why it didn’t survive this update.
My tablet has also LOS18.1 with magisk and there it survived the update.
Magisk isn’t supposed to survive OTA-updates without doing just a few extra-steps, according to the documentation you have to:
It is just that it survived every update. But not the one from today.
Currently on the 03/09/21 microg build.
On the whole I’m very happy with this though, so thanks!
#5. would be interesting for me, too. I’ve got this issue since LOS17µG.
Additionally, the battery discharges twice as fast as before this update. It’s like it was with LOS16µG. Maybe this fits with your #2. But I didn’t notice anything similar.
My battery wasn’t <10% but I’ll observe this.
Can’t conform #3. (no FP3+) and #4.
Strange: On one of the two slots, the install to inactive slot option disappears as soon as the first two steps are performed. I have to then sideload and install the magisk zip from recovery.
This happens only on one slot. So, i have to do this every second week.
Anybody experiencing the same?
More importantly, any idea why and how do I fix it?
#1. confirmed! Same issue.
Is a downgrade to the LOS17µG version before possible without any issue like upgrades are?
Excellent list, experiencing issues 1, 2 and 5 too.
If I may add a number 6: in LOS16.0 (not sure about 17.1) if my phone battery died it would still try to boot if you had set an alarm. E.g. if my phone would run flat during the night, it would still wake me up in time for work 
I have an interesting finding: I am on iodé which is based on Android 11, too. Yesterday evening I disabled mobile data and WiFi whith 15% charged. This morning the screen was black and charging wouldn’t start (at least the screen didn’t show anything, the notification light was off and it didn’t react to keys.) I didn’t try to hold the power button for 20 seconds, instead I removed the battery and put it in again, then charging started.
So maybe the problem is not rooted in this LOS port but in Android 11+FP3? Iodé is based on LOS, too, but I don’t know whether they are using this port as a basis.
the notification light was off
Just to add to this, last time this happened my notification light was on and flashing blue. This made me think I had a notification either before it froze, or perhaps even during? Good thinking on the rest of it though.
Now it happens in both the slots. The install to inactive slot in the Magisk App disappears as soon as the update is installed and before restarting.
Anybody else experiencing this?
I know I’m late to the party regarding this discussion, but my vote is strongly for including the Fairphone camera into the LineageOS ROM (or at least offer it as a flashable ZIP or as an APK). Snap is just way too simple in my opinion, and OpenCamera is starting to get annoying with the multi-second delay before taking a picture.
I tried once, but the app did not work reliably when simply copied onto the system. Right now I am using a Google Camera port, will post a link later. See also this discussion.
It has a few additional proprietary dependencies and a few arcsoft libraries.
Thank you for that link, I’ll test the Google one for now.
If I’m reading the nightly changelog correctly, it looks like some extra ambient display and raise to wake features are being introduced in the next build. Great stuff!
From our side we have now uploaded a hotfix to mitigate the auto-brightness problems. Fix will appear in next build cycle coming week.
Idea: define the minimum brightness at a reasonable level with display still readable. This should prevent insane behavior.
The Google “machine learning” thing is still very complex (every app gets its own brightness adjustment parameters) so I doubt people will be much happier with it. 
I’ve got terrible performance after upgrade to 18.1 and phone is extremely sluggish. Uninstalling some apps helped, but phone still lags a lot. Could a fresh install help? Or any other suggestions?
Well since you asked for suggestions, I would suggest you enable developer mode in the Settings menu (you will find instructions online), then hook up a data cable, install adb and run adb root, followed by adb shell top, to look for processes that are slowing down your device.
Try setting the performance-profile to max (more performance), that solved it for me. Only downside is it drains the battery a bit faster outside of sleepmode.
