Actions that trigger lockdown mode
Lockdown mode is triggered in the following situations:
• During a factory reset procedure.
• When Xperia™ Companion is used to wipe out user data.
• When the Google™ account that was used to activate Protection by my Xperia on
your device gets removed from your device (but not permanently deleted).
• When someone removes or tampers with security features on your device, for
example, when someone tries to input the credentials for the Google™ account that
you’ve used to activate Protection by my Xperia on your device but fails more than
three times in a row.
If you don't want lockdown mode to get triggered by any of the above actions or situations,
you can deactivate the Protection by my Xperia service.
