Lawnchair VS MagiskHidePropsConf

I would like to use Lawnchair on my Hi Reader Pro, but whenever I set it to use a third party launcher (obviously I haven't tried them all, but I tried 5 or 6 with the same outcome) the "Recent Apps" (Square Button) stops working after a few uses. By that I mean: nothing happens when it's clicked.

You can download it here: https://github.com/LawnchairLauncher/lawnchair

Could you please install Lawnchair Launcher & check if the notification is visible in the long press menu?

Launcher

And probably the most latest version (but not final release). https://github.com/LawnchairLauncher/lawnchair/releases/tag/v12.1.0-alpha.4

Lawnchair

It’s a module, but interestingly it seems to have been abandoned in the last couple of months. This module is primarily for spoofing the CTS Profile so that an uncertified OS like Lineage can appear to be a certified one like OOS.

I know MagiskHidePropsConf is depreciated and not developed anymore plus my model isn't in it's fingerprint database.

Maybe try magiskhide prop conf https://github.com/Magisk-Modules-Repo/MagiskHidePropsConf/

As others noted: it depends on the apps you'd like to use. I can recommend installing Magisk, enabling Hide, setting the Zygisk blacklist for the problematic apps and installing these modules - https://github.com/kdrag0n/safetynet-fix - https://github.com/Magisk-Modules-Repo/MagiskHidePropsConf

Yes, usually Universal SafetyNet Fix already does the trick, and sometimes (if you have root) MagiskHide Props Config is also required.

If you don't pass: Install the MagiskHide Props Config by Didgeridoohan, check again
