Green dot on my screen? What can it be?

Hi XavierNila,

Thanks for using Apple Support Communities. It sounds like you’re having trouble with an unexpected green dot on your screen. We’re happy to help.

To start, try restarting your iPhone to see if the issue persists:

If it does, we suggest reinstalling iOS to further isolate whether the issue is software related or not. While reinstalling iOS shouldn’t remove any data, it’s a good idea to have a recent backup:
