While exporting my game for Android, the colors and fonts of the game change. How do I fix this?

I made a game prototype and exported this project for Android. However, when I export my game for Android, the colors of the game become darker and the fonts change. I exported the same project for Windows for trial purposes and the same problem was not experienced. To ask you this question later, when I took the screenshot of the game on my phone and put the screenshot on the computer, I saw that the problem was gone. In other words, when viewing the same export from the phone, the colors are strange and the fonts change. However, when I view the same export with Windows, the problem does not appear. Then I decided to open my game with another phone to see if there was a problem with the screen of my phone. And when I looked with another phone, I faced the same problem again. In short, when I look at my game on the computer screen, there is no problem, but when I open my game on my phone, I encounter this problem. What do you think could be the problem? I made some nonsense because I didn't know how to explain it. I apologize in advance. (My English is not that good either :/) (I modified the screenshot with Adobe Photoshop to show you what the problem is.)

If this is only happening on that device, it's most likely not Construct's fault, it's just the way the device works. As for the font, most devices have a sort of "Default" font, so make sure you pick a specific font for your text, or use a web font (such as FontStruct.com) as those are universal.

First of all, thank you very much for your answer. I tried with 3 different devices and they all had the same problem. I wonder if I am doing something wrong while exporting my game, but I am still not sure. You might be right about the fonts. I'll try your suggestion. I have now emailed Construct officials for this color issue. If my problem is solved, I will share.

No problem! Btw I really do recommend FontStruct, it's free and you can find all sorts of fonts, or even make your own.

If you choose a local font available only on your device, and other devices don't have it, then those devices will pick a different font as a fallback, causing a different appearance. If you want a consistent appearance, try importing a Web Font and using that instead.

The color isn't changing - it's just an illusion caused by the different thickness of the text.

First of all, thank you very much for your answer. I think I can ensure that the font does not change with the suggestions of you and my friend above. But will this illusion, which I call the color problem, be fixed when I solve the font problem? Is this a general problem? Because it makes the game look pretty bad.

I used an image editor and checked the actual text colors. They're identical. The color does not change. It's just that sometimes thin lines look different to thick lines.
