Photo access across all apps

Hi there TKWharehinga,

Thanks for reaching out to Apple Support Communities. If you're wanting to allow third-party apps access to your device features such as camera or microphone, you can do so through your iPhone settings. You will have to individually grant access to each app you want to allow to use said features. By going into Settings > Messenger > Photos > All Photos the Messenger app will then have access to all of your photos. In this section you can also allow access to your camera and microphone. You can go through this same process with each third-party app you'd like to have access to your iPhone features.

We hope this helps.
