Reboot your device:

| Issue | Solution | | :--- | :--- | | | Your system partition is too small. Use a smaller GApps package (switch to MindTheGApps - it's the smallest). | | Setup Wizard keeps crashing | You flashed GApps after booting LineageOS once. Perform a Factory Reset and reflash both ROM + GApps. | | Play Store doesn't open / white screen | Clear data for Play Store & Play Services: Settings → Apps → See all apps → Google Play Store → Storage & cache → Clear storage. | | Device not certified in Play Store | This is normal for custom ROMs. Install "Magisk" and "Play Integrity Fix" module if you need banking apps. | | My device is 32-bit (arm v7) | MindTheGApps primarily supports 64-bit (arm64). Very old devices (2014-2016) may need legacy Open GApps 12.1 32-bit builds. |
