That is the latest update, and sure some default settings may have changed, finding them ??
But note the posts you refer to via the link are two years old though they do refer to a number of phones.
You may try disabling all your custom apps, one at a time to see if there is any change or do a safe mode start which disables all of them and then enable them one by one.
It is notable that this is only reported on the FP3 A11 not the FP4 A11 so the issue does point to the an update somehow, though you may have had updates to the custom apps you are using to.
Had the same behaviour after updating the Android version. It wasn’t the first time though, and in an earlier version I had to set the standard-start-app first to Quickstep and then back to Lawnchair again. Important was to do it in the standard app settings, not by answering the choice of the standard-start-app. This time I had to repeat this procedure, switching back and forth between the launchers a few times and did some restarts between, now it seems to remember the launcher again.
Edit: Seems I celebrated too soon, every now and then the choice dialog still appears. Most of the time it is when closing an app (opening list of most recent apps).
I haven’t been able to find a series of steps to fix this, even after trying various things. It would be nice if someone discovers a definitive procedure to get the setting to stick.
I use Nova Launcher and I am usually happy with it. The phone now asks which launcher to use about 1-2 times a day. It seems like a bug in the default Quickstep launcher, which cannot be completely disabled as it seems. It did not happen right after the last system update.
To Fairphone in any case, you should contactsupport. If ever it’s not their problem, they’ll tell you so or send that to the relevant service at Google.
This is not about the bug (since I use /e/) but did you try the KISS launcher?
If you only need one screen with widgets then this is the perfect launcher. The search is working really well, so besides a few main favourites I can open all other apps via checkin the whole list or open them via the search function, where I can find everything on my phone (apps, contacts, etc.) just by writing two or three letters in the search box.
I have the same issue since a week or ten days, with Nova Launcher (paid version).
The phone asks me what launcher to use about three times after I reboot it. I usually reboot my phone Evey morning.
It started some time after I updated to the June security update.
My guess is this may be related to some (Google?!) app or service updated in background lately.
Same here. It started today (16.8.22). I have to choose launcher almost every time I press the home button. It is infuriating. None of the proposed solutions above worked.
As many people (except I) use Gesture navigation probably this helps (from a Samsung forum where the exact same issue is described about 2 years ago)
1. Cleared default launcher.
2. Switched back to navigation buttons.
3. Restarted phone.
4. Switched to navigations gestures.
5. Chose my default launcher.
6. Upon restart, launcher was still saved.
Maybe also vice versa helps in case you dont use gesture navigation…
