Notification LED does not work (Galaxy S9 - starqltechn) #2093

Open 0xlynix opened 2 years ago

0xlynix commented 2 years ago

Seems the Samsung S9 is using the wrong LED Light HAL. In this result the S9 cannot work with the LED notification.

Using Android 12 PHH

lightsctl reports GOT TYPE BACKLIGHT

phhusson commented 2 years ago

OK, what does find /sys/class/lights | xargs ls -lZd report?

It returns : phhgsi_arm64_ab:/ # find /sys/class/lights | xargs ls -lZd find: '/sys/class/lights': No such file or directory drwxr-xr-x 30 root root u:object_r:rootfs:s0 4096 2018-02-22 03:09 . phhgsi_arm64_ab:/ #

(I think the path is incorrect)

Hello, I have a similar issue on my Doogee S88Pro with a treble GSI. The indication works but I get quite many SELinux warnings and errors in the log which might be causing a bit of lag. My device is not even close to Samsung so the warning is quite strange. Here in the logcat:

02-11 20:13:09.053   347   347 E SELinux : avc:  denied  { find } for interface=vendor.samsung.hardware.light::ISecLight sid=u:r:system_server:s0 pid=1438 scontext=u:r:system_server:s0 tcontext=u:object_r:default_android_hwservice:s0 tclass=hwservice_manager permissive=0

And even worse is this (happens 2-3 times a second):

I also have the leds under another directory:

Is there any workaround for me? Maybe I can edit something somewhere so it just stops all this flood?
