If the screen share icon in FaceTime is greyed out, it usually means one or more requirements aren’t being met: either a software, settings, or connectivity issue. Here’s how to fix it.
FaceTime screen sharing only works if both parties are using:
Both people must be signed into iCloud with their Apple ID. Compatibility issues are the most common reason screen sharing doesn’t appear.
Sometimes the simplest fix is the right one:
After relaunching FaceTime, check if the screen share option is now active.
A slow or unstable network can disable advanced FaceTime features. To improve connection:
FaceTime screen sharing needs a stable and reasonably fast connection to work properly.
FaceTime screen sharing is powered by SharePlay. If it’s turned off, screen sharing will be unavailable.
Make sure SharePlay is toggled on in both cases.
Older operating systems may not support FaceTime screen sharing, even if you see the icon.
Once updated, relaunch FaceTime and test screen sharing again.
Strange but true. Emojis or non-standard characters in a contact’s name may interfere with FaceTime features. Edit their name using only plain text, then try again.
Sometimes generating a FaceTime link can bypass call-based bugs:
Then check whether the screen share button is still greyed out.
If your connection seems fine but features still don’t work, try resetting your network settings:
This will remove saved Wi-Fi passwords, so reconnect manually after the reset.
If none of the previous fixes work, you can try deleting and reinstalling FaceTime. While it’s a system app and not fully removable, reinstalling can reset permissions, clear caches or fix app-specific glitches.
Here’s how:
This won’t fix issues caused by software incompatibility or network problems, but it may help if the app itself is bugged or misconfigured.
In some cases, the screen share button stays greyed out due to a temporary bug in Apple’s OS. If everything else checks out, there may be nothing to do but wait for a software update from Apple.
Now you've done all the checks, ensuring a reliable connection is paramount. If you're using FaceTime screen sharing while traveling, we're sure you'd like to share your trip experiences too. Instead of relying on spotty hotel Wi-Fi or expensive roaming plans, you can stay reliably connected with Eskimo eSIM. It works in over 130 countries, supports personal hotspot for iPads and Macs, and offers fast, unthrottled speeds, perfect for FaceTime screen sharing, even on the go.
New users can get 500MB of global data free to try it out, no strings attached.
This usually happens when one or both devices are using outdated software, SharePlay is turned off, or the users are not signed into iCloud. Both devices must meet Apple’s minimum system requirements.
Go to Settings > FaceTime > SharePlay, and make sure the toggle is turned on. On Mac, open the FaceTime app and check the SharePlay settings in the preferences menu.
Yes. If your Wi-Fi or cellular connection is weak or unstable, FaceTime may disable features like screen sharing to preserve call quality.
No. FaceTime screen sharing is only supported between Apple devices. Android and Windows users can join FaceTime calls via link but cannot use screen sharing or SharePlay.
In some cases, using emojis or unusual symbols in a contact’s name can interfere with how FaceTime handles the call. Rename the contact using plain text and try again.
