(0.13 android version) White font text, on a white background, on a mostly white area is not a very readable experience, giving the text a black outline would greatly help
Unfortunately there are certain scenes where you can't see the white font. I could just make the background for the font less transparent, but then you won't see the bottom of the image. you can lower the brightness of the screen or better yet turn on night screen mode. this works on both smartphones and computers.
