Hello, I own an Asus Zenpad S 8.0 (Z580CA) tablet and I like it. However there is one detail that is rather annoying. Although Brightness is set to fixed, and I’ve disabled any power saving option I could find, the screen brightness automatically drops if the image on the screen is darker. It also goes brighter when, you guessed it, the image on the screen is in brighter colors. How the !&&* do I disable this? My head hurts because of frequent brightness changes. I’ve found answers on Google only for Windows. Thanks for any help!
Hi, Found this quote, taken from this link http://www.zenpad.org/2015/10/z580ca-rev… which may be of interest to you. “If you feel the need to tweak the display there is an Asus app “Splendid”. This app allows you to adjust the display in a number of ways including color temperature, hue, saturation, and some presets like Balance, Bluelight Filter, and Vivid. The flexibility is in the hands of the user when it comes to visuals, so if you don’t like what you see, go ahead and tweak away”. Here is a link to the app. https://play.google.com/store/apps/detai… Also have you checked that you have the latest firmware installed? Depending on your version there are some released as late as Jan.2016 and Dec 2015. Here is a link, select your OS -Android https://www.asus.com/Tablets/ASUS_ZenPad… Hopefully this is of some help.
Well, it looks like the zenpad has a lot of hardcoded stuff, bloatware etc. I googled some more, and it seems more people complained about this even about laptops: https://rog.asus.com/forum/showthread.ph… http://www.transformerforums.com/forum/a… https://www.reddit.com/r/techsupport/com… and even some for Dell, where it seems they released a patch. But these people have windows and you can disable that. I tried Brightness Adjuster & some other software to no avail. What’s funny is even with automatic brightness, this fluctuation happens. Because it relies on the screen content. So even if I set a fixed brightness of 30, or the Auto one is 50, there still is a plus/minus variation for dark and bright pages. And this is more annoying the bigger the screen, like the people with laptops say. I have a technical complaint with Asus, I’ll see where that goes.
Delete or rename file \system\lib\libdm_dpst.so and reboot. I did this and it works. I renamed it libdm_dpst!!!.so It is Intel DPST (Display Power Saving Technology) PS: you need root permissions to do this.
I have this issue on Asus ZenFone 3 ze520kl. This is a new issue after a firmware update in mid May 2017. Very annoying, I may have to replace the phone.
