Hi Hampshirelad,
Thanks for posting. We'd like to get an understanding of your question to see how we can help out.
Can you clarify which app you're referring to? Knowing this will help narrow things down and work out the best steps you can try for troubleshooting.
Also, when you say they're on the side of the screen, where are you referring to?
If you're referring to Messages, you might mean the iMessages apps as shown here. With iOS 17, the microphone icon is replaced by a red waveform icon that you can see below: Use iMessage apps in Messages on iPhone - Apple Support
"Use iMessage apps in Messages on iPhone
You can play a game, record audio messages, share songs, and more—all through iMessage apps—without leaving the Messages app
. You can customize the list or expand your options with iMessage apps you find in the App Store.
"
If that's not what you're referring to, try to Restart your iPhone and test to see if that helped. Let us know.
Cheers.
