Huawei Y6 - ATU-L11 Display Brightness

[cl4r0s]

Hello phhusson First of all, thank you for your incredible work on treble project! I would like to submit an issue about this device:

[ro.build.description]: [ATU-L11-user 8.0.0 HUAWEIATU-L11 153(C55) release-keys] [ro.build.display.id]: [ATU-L11 8.0.0.153(C55)]

But this problem seems to be in common at least with the whole Huawei Y6 series, ATU-L03, L11, L21, L22 and LX3 The problem is the Display Brightness too low. I've made some search inside the os: /sys/class/leds/lcd-backlight/brightness has a range from 0 to 255 but for this device /sys/class/leds/lcd-backlight/max_brightness is 1023 This command echo $(cat /sys/class/leds/lcd-backlight/max_brightness) > /sys/class/leds/lcd-backlight/brightness can rise the brightness but the AutomaticBrightnessController just put it back to the range 0-255 so at the sunlight the display is not well readable

My actual Rom is Descendant ThreeDotZero for Treble Enabled Devices Oblviosly I'm avaliable for any other informations you may require. Best Regards /claros

Uh, that's a real vendor/boot?

[ro.build.description]: [ATU-L11-user 8.0.0 HUAWEIATU-L11 153(C55) release-keys] means that it is an oreo vendor

but [ro.boot.product.hardware.sku]: [ATU-L11] looks like a pie vendor...?

This is stock oreo vendor? Is it a recent one? like what security patch level?

Please provide getprop persist.sys.qcom-brightness

Please check if one of those commands set backilght to max:

lightsctl BACKLIGHT ffffffff
lightsctl BACKLIGHT ff
lightsctl BACKLIGHT 3ff

[cl4r0s]

Original ROM was an Oreo, vendor C55 is TIM (Italy), Version 8.0.0.153 is a new release with security patch level 02/2019 but it is not the latest one (8.0.0.155) which is known to cause bootloops on gsi roms.

Here the output of the commands: HWATU-QG:/ # getprop persist.sys.qcom-brightness

<NOTHING, not present>

Instead: HWATU-QG:/ # lightsctl BACKLIGHT ffffffff Got type BACKLIGHT Got type BATTERY Got type NOTIFICATIONS Got type ATTENTION Set request type BACKLIGHT Set flash type to NONE Set light returned SUCCESS HWATU-QG:/ # cat /sys/class/leds/lcd-backlight/brightness < 255

HWATU-QG:/ # lightsctl BACKLIGHT ff Got type BACKLIGHT Got type BATTERY Got type NOTIFICATIONS Got type ATTENTION Set request type BACKLIGHT Set flash type to NONE Set light returned SUCCESS HWATU-QG:/ # cat /sys/class/leds/lcd-backlight/brightness < 28

HWATU-QG:/ # lightsctl BACKLIGHT 3ff Got type BACKLIGHT Got type BATTERY Got type NOTIFICATIONS Got type ATTENTION Set request type BACKLIGHT Set flash type to NONE Set light returned SUCCESS HWATU-QG:/ # cat /sys/class/leds/lcd-backlight/brightness
30

The only command I found to increase backlight is echo 1023 > /sys/class/leds/lcd-backlight/brightness and with getprop | grep -i backlight i got no results

Best regards claros

Better to to post it as a text file... https://pastebin.com/hXvS0FDs

huawei-lights.zip

Download this, push both those files in /data/local/tmp/, and try this:

> adb push vendor.huawei.hardware.light@2.0.so /data/local/tmp/
> adb push lightsctl-huawei /data/local/tmp/
> adb shell
$ su
# LD_LIBRARY_PATH=/data/local/tmp/ /data/local/tmp/lightsctl-huawei 0 0
# LD_LIBRARY_PATH=/data/local/tmp/ /data/local/tmp/lightsctl-huawei 0 255

# LD_LIBRARY_PATH=/data/local/tmp/ /data/local/tmp/lightsctl-huawei 0 1023

If it still doesn't set backlight, you might try to with other values than 0 as first argument

[cl4r0s]

Thank you for your support, but in Descendant 3.0 there is an incompatible library:

Can you please share at least an android.hidl.base@1.0.so build for Android 28 or build lightsctl-huawei including libraries?

Regards, Claros

[cl4r0s]

I've flashed your AOSP treble_experimentations but it's the same: ind /system -name android.hidl.base@1.0.so < /system/lib64/vndk-26/android.hidl.base@1.0.so /system/lib64/vndk-sp-26/android.hidl.base@1.0.so /system/lib/vndk-26/android.hidl.base@1.0.so /system/lib/vndk-sp-26/android.hidl.base@1.0.so

Vendor from Oreo 8.0 use Android 26... Regards, Claros

[phhusson]

I don't understand, why are you mentioning android.hidl.base@1.0.so at all?

[cl4r0s]

ldd is not direcly avaliable on platform... but in your roms I found at the same time vndk-26, vndk-27 and vndk-28. So tried to play a little with LD_LIBRARY_PATH but the needed android.hidl.base@1.0.so is just on vndk-26. I don't know why it's linked but a simple strings lightsctl-huawei show it's dependencies.

[phhusson]

None of the files I've included ( vendor.huawei.hardware.light@2.0.so and lightsctl-huawei) depend on android.hidl.base@1.0.so:

phh@phh-desktop:~/tmp/t$ unzip -p ../huawei-lights.zip|grep android.hidl.base@1.
phh@phh-desktop:~/tmp/t$

If I had to guess, I'd say that you didn't copy the vendor.huawei.hardware.light@2.0.so from the zip to /data/local/tmp/

[cl4r0s]

Please have a look:

1|HWATU-QG:/data/local/tmp $ pwd /data/local/tmp HWATU-QG:/data/local/tmp $ ls -la /data/local/tmp

I suppose everything is at the right place, am I wrong?

[phhusson]

Except that it must be run as root, yeah looks correct

[cl4r0s]

Sorry, just in the previous example I din't but: HWATU-QG:/ $ su HWATU-QG:/ # cd /data/local/tmp
HWATU-QG:/data/local/tmp # LD_LIBRARY_PATH=/data/local/tmp/ /data/local/tmp/lightsctl-huawei 0 0 Segmentation fault 127|HWATU-QG:/data/local/tmp # ls -la total 220 drwxrwx--x 2 shell shell 3488 2019-06-14 17:44 . drwxr-x--x 3 root root 3488 1970-07-09 09:47 .. -rwxrwxrwx 1 shell shell 68872 2019-06-14 00:14 lightsctl-huawei -rwxrwxrwx 1 shell shell 135928 2019-06-14 00:12 vendor.huawei.hardware.light@2.0.so HWATU-QG:/data/local/tmp #

[phhusson]

k, well the error should be in logcat then

[cl4r0s]

What if I substitute your vendor.huawei.hardware.light@2.0.so whit the one in my vendor? I'm trying it now...

[phhusson]

it will be even more broken because lightsctl-huawei isn't built to run on it. but just give logcat logs when running with my tools

[cl4r0s]

Could you please compile lightsctl-huawei using the vendor.huawei.hardware.light@2.0.so from my /vendor/lib64? vendor.huawei.zip

[cl4r0s]

Logcat log attached, with the vendor.huawei.hardware.light@2.0.so you provided, obviously

logcat.zip

[cl4r0s]

The error is infact in the log... I've excuted twice with 0 0 and 0 1023 as parameters

[phhusson]

Ah, issue is that service is called ILight not IHwLight I'll need to check when I get back home if I just did a typo, or if the name depends on the device.

In the meantime, try again with the files attached here huawei-lights.zip

[cl4r0s]

No segmentation faults, but doesnt work:

[phhusson]

try changing the 0 to other values

[cl4r0s]

Sorry but I'm abroad for some time and I don't have a development PC. In addition I don't have a plan for the sim in this country so it's pretty complicated. I kindly ask you to keep this bug on standby, anyway I will try to ask other owners if it is possible to do the necessary tests. Regards Claros

[cl4r0s]

I came back but my device has been quarantined by vpn/echange as it was rooted/unlocked... :-( As I'm now in a blacklist, I have to stay at least for some time with the stock rom :-( In add, 146 people having the same device don't had enough time in more than a week to test your brightness patch... With a stock rom your patch doesn't work, obviusly. I did some debug inside the stock, log attached. I really don't know if I can help you with this rom, anyway AFIK it seems that with this build https://sourceforge.net/projects/andyyan-gsi/ this problem is not present... If this is a personal bug, I really don't want to take your time anymore. Best regards

Hello. i have the ATU-L21 and same problem in Custom Roms (brightness issue). I Tried this too but nothing works only echo $(cat /sys/class/leds/lcd-backlight/max_brightness) > /sys/class/leds/lcd-backlight/brightness via terminal to set brightness to max.
