2.Installation
Google apps should be installed via recovery immediately after installing LineageOS. Exact steps vary, but the process is similar to that of installing LineageOS:
IMPORTANT: If you reboot into LineageOS before installing Google apps, you must factory reset and then install them, otherwise expect crashes.
Copy the Google apps zipfile to /sdcard/
After installing LineageOS, choose “install zip” or “Apply update” in recovery, and navigate to the zipfile loaded earlier.
Reboot back in to Android
