Systemizer is a Magisk module that is able to move apps from a user directory and into folders restricted to system apps. This has the potential to mitigate issues regarding apps being killed near completely.
Installation
- microG must be installed with signature spoofing enabled (see the Signature spoofing section of the Using microG page).
- Download Systemizer from this link: https://sourceforge.net/projects/magiskfiles/files/module-uploads/terminal_systemizer-70.zip/download
- Copy the zip onto your phone in the downloads folder.
- Open Magisk and install the zip file, reboot if prompted.
Usage
Apps installed to the SD card cannot be systemized. You will need to move the app to internal storage through the Android settings menu. You can find additional details in the Adoptable storage section.
Systemizer is accessed over ADB. Open a terminal with ADB and enter in this sequence:
adb shell
su
(Allow if prompted)
systemize
A menu will be displayed from which you can choose to install an app from an APK file on the phone or systemize existing apps.
You can systemize multiple apps at once, but I do not recommend doing so in large batches as the phone may run out of disk space and you'll need to manually clean up corrupted apps.
You will be given a choice to systemize to “Priv” or “Apps”. “Priv” stand for privileged, and generally is higher in the system hierarchy which works best for some apps, but will not work for others. Most apps work best in “Apps” but trial and error will likely be needed to see which works better for the app. You will need to reboot the phone to see the effect.
Both of these options will give the effect of keeping your apps alive if the app does not break in the process.
Systemized apps will always be running in the background, and will all be loaded on the phone when booting up. Because of this you cannot have too many apps, or too large of apps systemized.
Notes
Due to systemized apps not seeming to be affected by battery saving processes at all, the battery will drain much faster. You should consider looking at apps and seeing if they are causing more battery drain then others because of this.
