I can’t really tell what you’re trying to show with that screenshot. What do you mean by “function buttons”? Do you mean button components? If so, see this: > **[Button](https://docs.thunkable.com/button#background-color)** > > When you tap on the play icon to hear your favourite music, you are using a button. If not, can you show a larger/more detailed screenshot or explain more? ---

these buttons are in every phone. (with android). When I create apps their background is gray and I can’t find an option to change the background color of these buttons. ---

So those are the operating system buttons. There is no way inside Thunkable to control them. You need to check, if available, in the phone settings. ---

each application changes the color of this background, although I do not change anything in the settings. ---

Please provide a video of what you’re seeing or a screenshot that shows the whole screen… not just a few buttons. It’s really hard to understand from what you’ve shown. Is this happening on the Design tab or only when tested on an Android device? ---

These are the **Android navigation keys** and cannot be changed by any application. The background of these keys in **transparent** and therefore if you change the screen background to **green** and run your app from the phone you will see these buttons’ background **green** but this is not a change of the buttons. They stay with transparent background. If you see something different then please show it in a short video as suggested by @tatiang so we can understand what you are trying to describe. ---
