The timetable for the long-delayed Samsung deployment of Android 15 has now seemingly leaked—again, and it’s bad news for all current flagship users. While S24 users may get the beta next month (country-dependent, of course), S23 and S22 users will see further delays and S21 users may not get anything at all. As for the stable release, we know that’s not coming until next year to coincide with the S25.
