# Enabling this property will skip verification post OTA reboot.

# Verification allows the device to safely roll back if any boot failures

# are detected.  If the verification is disabled, update_verifier to will

# try to verify using bufferred read if care_map.pb is present in

# /metadata/ota/. This will increase the boot time and may also impact

# memory usage as all the blocks in dynamic partitions are read into page-cache.

# If care_map.pb isn't present, update-verifier will skip the verification.

# PRODUCT_VENDOR_PROPERTIES += ro.virtual_ab.skip_verification =true

# Enabling this property, will improve OTA install time

# but will use an additional CPU core
