That sounds like an interesting update for the Alldocube iPlay 30 Pro! Upgrading to Android 13 with Arrow OS GSI (Generic System Image) can bring new features, enhancements, and potentially better performance to your device.
Arrow OS is known for providing a clean and close-to-stock Android experience with some additional customization options. By using a GSI, you can experience the latest version of Android on your device, even if the manufacturer hasn't officially released an update.
Just keep in mind that installing custom ROMs like Arrow OS can void your warranty, and there is always a risk of potential issues during the installation process. Make sure to follow the installation instructions carefully, back up your data, and be prepared to troubleshoot in case of any problems.
If you have any specific questions or need help with the installation process, feel free to ask!
