Magisk app Issues
Can't install the Magisk app
If the Magisk app doesn't get installed when you flash the Magisk zip, or that you're trying to install the apk manually and it doesn't work, you might first have to remove remnants of an old installation. This can be done through ADB. Start by uninstalling any currently installed app (especially if it's repackaged with a random package name) and then just run the following command from ADB Shell and you should be good to go:adb uninstall com.topjohnwu.magisk
Problem parsing the package
"There was a problem while parsing the package". If you see this message while trying to update the app and the app is hidden, go to the app settings and choose to "Restore Magisk app ". The new app release will be downloaded and installed with the regular package name and you'll just have to rehide the app again afterwards.If you don't have the app hidden, but still see this message, try clearing the app cache, or if that doesn't work uninstalling the app and reinstalling it again (you'll find the apk on GitHub).
Clearing cache and data
If there are issues with the Magisk app, it's often a good idea to clear data for the app. All your granted superuser requests and apps added to the MagiskHide list will still be intact (since they're saved elsewhere).Latest show "N/A"
If the information for the latest available Magisk or app just show N/A you either do not have internet access (or you have something blocking internet access for the app), or you might have an invalid link set for the custom update channel in the app settings. This could be, for example, caused by the links to the Canary channel json file has changed.Tip: Instead of putting the link to the Canary channel in a custom update channel, simply download the Canary app from GitHub and pick the make sure the Canary update channel is selecte in the app settings. That way you won't have to keep track on if and when topjohnwu changes the link.
Magisk app crashes/freezes
If you're having issues with the Magisk app force closing/crashing/freezing at any point, clear data for the app or uninstall it and install it again. Note that you might have two apps installed, the regular Magisk app and a hidden one with a random package name. You'll need to uninstall both...Theming
The app crashing might also be caused by using a theme engine to theme the app (Substratum, etc). Disable it and reapply after an update to the app .Magisk app installed to external/adoptable storage
Installing the Magisk app to an external or adoptable storage is known to cause issues. Reinstall it to the internal storage.Magisk app as a system app
Another reported reason for the app crashing is if you've for some reason added the Magisk app as a system app. If this is the case try de-systemising to see if that fixes the issue.Trying to install modules in the Modules tab
If the app crashes when pressing the "Install from storage" button in the Modules window, it's likely caused by your ROM not having a file explorer installed. Install one from F-Droid or the Play Store.Cant' fix
If there still are issues, capture a logcat from the crash/freeze and post it in the support thread or as an issue on GitHub (just make sure to do it properly), with a detailed description of the problem (also see "Asking for help/reporting bugs").There are two Magisk apps
If there suddenly are two Magisk app in your app drawer, this might be caused by somehow installing a new app while having the old one repackaged (hidden) with a random package name. It can happen when updating Magisk, and usually if you install the app apk manually, or if you use the Magisk zip in recovery while having a repackaged app installed. Also, the uninstaller zip (the Magisk app apk renamed to uninstall.zip) cannot uninstall the repackaged app (since it doesn't know the random package name), and you'll have to uninstall the old app manually. Or something else... If the duplicate app doesn't disappear (it'll be uninstalled by the "real" app) after you open the one named just "Manager" (or whatever name you've picked), the best thing is probably just to uninstall both and install the app again (apk can be found on GitHub). It might also be necessary to delete /data/adb/magisk.db. Also see "Can't hide the Magisk app" below.It's also possible that you'll get two apps installed when trying to hide (repackage) the app. If you have made the app a system app, or the ROM you're using has the app pre-installed as a system app, the repackaging feature can't uninstall the old app (because it's a system app) after having installed the new one with a random package name (the app might get stuck on "Hiding it now"). Remove the app from /system/app or /system/priv-app (depending on where you or the ROM creator have placed it). If the app comes pre-installed as a system app, please let your ROM creator know that it's a bad idea to include the app like this.
If your ROM doesn't come with the Magisk app installed as a system app, or you haven't made the app into a system app, if disabling Play Protect doesn't help, or if the app can't be hidden/repackaged at all, please provide details and logs (see "Asking for help/reporting bugs").
Can't hide the Magisk app
First thing to try is to temporarily disable Play Protect in the Play Store. From v7.4.0 the app uses a stub apk to hide fully on Android 9+ systems. This sometimes triggers Play Protect which will silently block the install, and you'll just get a "Hide Magisk app failed" message. On some devices this might be caused by SELinux issues, so if the above doesn't work, try changing SELinux to permissive when you hide the app.If you have a Xiaomi device and MIUI, you might have to turn on "Install via USB" in Developer options before trying to hide the app.
Can't restore the Magisk app
If you can't restore the Magisk app, either that it gives an error or nothing happens at all, the easiest way is to simply uninstall the hidden/repackaged app and install the apk manually. The latest stable app apk can always be found on GitHub.It might be necessary to remove any remnants of old installs through ADB before the app can install again (see "Can't install the Magisk app" above).
