<br>

If your Fairphone 5 is still running **Android 13**, please note that migration support to /e/OS based on **Android 15** will only be available starting with release **v3.3**.

<br><br>Do **not** attempt to upgrade directly from Android 13 to Android 15 before v3.3, as this will not be supported and may result in issues.  

<br><br>Users already on **Android 14** can upgrade to **Android 15** as planned." %}
