Hi everyone,
Thank you for your patience and for sharing your experiences regarding the FP5 boot issue following the Android 15 update.
What we’ve discovered
From our diagnostics, it seems that:
-
In some cases, the fingerprint sensor was working intermittently, which allowed the update to Android 15 to complete and the phone to boot at least once.
-
If the fingerprint sensor then stopped working afterward, the device is recognized as having successfully installed and started Android 15.
-
This means a rollback to Android 14 is no longer possible once Android 15 has been initialized.
What this means for affected devices
For devices in this situation:
-
Repair is the only option if the phone can no longer boot.
-
Even if we release a future fix, users whose phones are already stuck on A15 without booting will not be able to simply install it as a normal update.
-
The only ways to apply the fix will be either:
-
Sending the device for repair.
-
Both options require a factory reset and will result in data loss.
Next steps

Our teams are actively working on a long-term solution so this issue won’t recur in future updates.
