Multiple reports suggest that the Android 15 update is causing some Fairphone 5 handsets to become bricked, but only if they already had an existing biometric fault.According to a user and several respondents on the Fairphone Community Forum, the update is freezing some Fairphone 5 devices on the boot screen and making them unable to start. In each case, the phone gets stuck partway through the Fairphone boot animation, displaying only a green “I” on a blank screen. The only way to recover appears to be rolling back to a previous Android version or wiping the device entirely.
