No. The Kosher Qin Phone runs Android 11, and it can’t be upgraded to Android 12, 13 or newer.
The 2.0 upgrade updates our own filtered system on top of Android. It doesn’t change the Android version.
What this means for apps
Some apps need Android 12 or newer. These apps show “Unavailable” in the app store and can’t be installed. There’s no way to force them to install. See “An app says Unavailable or not available for your device.”
