As part of IT security best practices, Google Android enforces that the Security Patch Level (SPL) for the
new OS or patch must be the same level or a newer level than the OS or patch version currently on the
device. If the SPL for the new OS or patch is older than the SPL currently on the device, then the device
will factory reset and wipe all user data and settings including user network configurations and remote
management tools which would render the device inaccessible over a network.
Therefore, please check before updating to the latest LifeGuard Release to see if the update supports
the Acoustic Profile preloaded on device.
