Why does my Samsung A8 have such poor contrast after updating to Android 9? I have a Samsung A8 2018 SM-A530W, which was purchased from a major Canadian carrier. It recently updated itself to Android 9 through a Samsung application.

Since that update, many of my applications are very difficult to read. In the case of Calendar and Clock, the contrast ratio between the text and background makes text illegible. In the case of the settings screen, transparency to the wallpaper does the same. I'm sure this isn't intentional, but I'm wondering what I can do besides reset my phone.



White text on an almost-white background makes the calendar impossible to read.



Gray text over a gray background makes the clock difficult to read.



Black text over a transparent background to the default Galaxy wallpaper makes settings difficult to read.
You can change that.


Go to Settings -> Accessibility -> Visibilty enhancements -> then try some functions there and see what is best for you (contrast theme,contrast font etc.)
If you are using any Galaxy Theme, after system update, they are also updated, so this can alse be a problen. You should try to change or just dissable theme you are using(if you are using) for a moment to test it.
If you love Night Mode,it can also solve your problem, but it is not good for using outside.
