I have disabled the fingerprint sensor on my phone by setting the device tree node status to disabled. When I boot up, the fingerprint menu options are gone, but dmesg shows that hwservicemanager is trying to start a fingerprint sensor over and over, but init can't find the service:
[ 625.488742] init: Could not find '[email protected]::IBiometricsFingerprint/default' for ctl.interface_start
[ 625.502583] init: Received control message 'interface_start' for '[email protected]::IBiometricsFingerprint/default' from pid: 669 (/system/bin/hwservicemanager)
[ 625.502658] init: Could not find '[email protected]::IBiometricsFingerprint/default' for ctl.interface_start
[ 625.523352] init: Received control message 'interface_start' for '[email protected]::IBiometricsFingerprint/default' from pid: 669 (/system/bin/hwservicemanager)
[ 625.523427] init: Could not find '[email protected]::IBiometricsFingerprint/default' for ctl.interface_start
[ 625.538080] init: Received control message 'interface_start' for '[email protected]::IBiometricsFingerprint/default' from pid: 669 (/system/bin/hwservicemanager)
[ 625.538545] init: Could not find '[email protected]::IBiometricsFingerprint/default' for ctl.interface_start
How do I tell hwservicemanager to stop trying to start this now non-existent service? I saw here that there is an option to remove the hidl definitions from a manifest file, but I would like to enable or disable the fingerprint sensor at runtime. I can enable and disable the service with start vendor.fps_hal and stop vendor.fps_hal, but I can't stop hwservicemanager from trying to start it.
