[Redmi Note 7] Brightness is at maximum but the slider is only at 50%

[leonardoaranha-git]

The brightness is at maximum but the slider is only at 50%.
Don't know what files you need to debug this..

[phhusson]

That's a very vague issue.
Do you mean backlight control doesn't work at all?
Or it just doesn't do what you want it to?

[leonardoaranha-git]

Sorry for bad explanation.
When I put slide bar of brightness in 50%, the brightness of display go to 100%.
The brightness of the display reaches the maximum when I put the slide bar in 50%.

e.g.
slide bar 0% ~ 50% = display brightness 0% ~ 100%
slide bar 50% ~ 100% = display brightness always 100%

Assuming you have root privileges, from "terminal" app on your phone or from ADB shell type the following to temporary fix:

adb shell
su
setprop persist.sys.qcom-brightness 4095
reboot

I already tried that too.
This command is only to correct the brightness flickering bug.

simple thing...

cat /sys/devices/soc/c900000.qcom,mdss_mdp/c900000.qcom,mdss_mdp:qcom,mdss_fb_primary/leds/lcd-backlight/max_brightness
4095

cat /sys/devices/soc/c900000.qcom,mdss_mdp/c900000.qcom,mdss_mdp:qcom,mdss_fb_primary/leds/lcd-backlight/brightness
reaches the max value (4095) exactly at 50 per cent of the slider...

[phhusson]

Well then try with the property at 2047 instead?

[darkestDark]

already tried... only "goal" is that brightness stops at this value... but it got full brightness at that value, too.
when reaching 50 percent on slider maximum brightness is reached.

you can add each value as long at it is not bigger than 4095.

solved with v114 for me...
But only because the overlay hasnt appllied... so its caused by wrong values in the overlay. will take a look at it if there is some time and take the values from actually framework-res.

[darkestDark]

its confusing me a bit...

logcat:

Skipping target and overlay pair android and null: overlay ignored due to required system property: ro.vendor.build.fingerprint with value: +*iaomi/lavender*

but...

 getprop ro.vendor.build.fingerprint
xiaomi/lavender/lavender:9/PKQ1.180904.001/V10.2.7.0.PFGMIXM:user/release-keys

i will build the overlay on my own and test it...

[darkestDark]

Fixed...

You can ignore that log, that's for non static RROs, this one is static Le lun. 10 juin 2019 à 17:20, darkestDark <notifications@github.com> a écrit :
