Yellow Tint on certain app

[drkathy]

Hi! Whenever I open the Google Play Books app, may screen starts to have a light yellowish tint and turns back to normal upon closing the app. Doesn't happen to my other phone and tablet. Night Light options are all off. Does anyone know how to fix it? 😊

This seems to be a known issue (or feature) in Play Books app. Some suggests to change the background to a different colour. Maybe black is better?

Perhaps you also need to check if Bixby is activating eye comfort shield whenever Play Books is open.

I don't use the app. I just checked online.

I wanted to post around the "solution" I found, since seeing so many forums with others experiencing the same problem I had (ranging from 2020 to 2024 with numerous Samsung devices).

After using ADB to switch screen modes while having an ebook app (Kindle, Google Play Books, etc.) open on my Samsung Galaxy Tab S9, I noticed that though the white balance wasn't changing, the color saturation actually was. After adjusting the white balance of the "vivid" screen mode to match what is the forced default in eBook apps, I found out that what is actually happening is that Samsung devices have a built-in setting that when an eBook app is opened, your white balance customizations are bypassed and brought to the warmest setting on the white balance slider.

I've tried just about everything people have suggested; but apart from root, Samsung won't let any other app change the native settings like this. The "solution" I found is a workaround. As only two forum commenters I found suggested, turn on the eye comfort shield, and set it to the least warm setting. On my tab S9, this is actually equivalent to the 2nd warmest setting of "vivid" screen mode's white balance slider. While this isn't as ideal as being able to stop eBook apps from messing with your own white balance preferences, to me it at least makes the display tolerable while using them.

Furthermore, with devices like this, there's a "Modes and Routines" setting which allows you to activate certain display adjustment whenever a certain condition is met. I set the "condition" to be whenever Kindle or Google Play Books is opened. Though you aren't able to cause the "mode/routine" to change your screen mode or white balance settings, you can set it to activate your eye comfort shield at whatever intensity you choose (independent of your normal eye comfort shield settings). So now I can take advantage of my custom white balance settings during normal use, my very warm eye comfort shield settings at night, and have the coolest eye comfort shield setting to activate whenever I open eBook apps. And during night, if I want to use an eBook app and don't want the "mode" to cool the screen down, I just hit the cancel button which pops up briefly at the top of the screen to cancel the mode's settings before they activate.
