I have an Honor phone (not rooted) and I dislike the default launcher, so I installed a new one. It worked, but even after switching the default in the settings, the settings kept changing themselves after a while to return to the default launcher. This happened with both Foss-ify’s Launcher and Kiss Launcher, so it doesn’t seem to be due to a failure of the selected launcher.
Next thing I intended to try was force stop Honor Home, but I’m a bit worried about doing that, because what if the phone still starts refusing to launch the installed launcher but can’t find the old one either and doesn’t launch anything? Will I find myself unable to open any apps (including the settings to revert this) if that happens?
You can boot into safe mode. That ought to give you a working environment to fix problems.
Usually if Android doesn’t have a default launcher it’ll ask you to pick one when you hit the home button.
Maybe start with removing permission to change settings of the honor home app?
That way it can’t reset the launcher
