The Samsung Galaxy S6 has the most bright and vibrant mobile display of all the devices we’ve known, but there’s this auto-brightness bug on the Galaxy S6 edge and edge+ variants of the device which limits the display brightness even when auto-brightness feature is turned off.

Thanks to ultimatewaffel over at xda, we now have a fix for this annoying bug on S6 edge and edge+.. at-least for the international variants of the said devices (G925F and G928F).

Because of the nature of the bug, there’s no universal fix that you could apply to it. The fix is actually different for each firmware even for a particular model number. So be wary of your device’s firmware version and choose the patch accordingly from either the download links below or the original thread at xda.

The patch involves replacing the services.jar file from /system/framework/ directory on your device. Grab the services.jar file according to your device’s firmware version replace the file using file manager app with root access.

Also, note that this patch will only work if you’ve a deodexed ROM installed on your device. If you’re running an unmodified stock ROM, then it isn’t deodexed and so this patch will not fix the auto-brightness bug on your device.
