Hi Sunnyahlawat_8400,
Thanks for contacting Apple Support Communities!
We understand that your callers aren't able to see you on FaceTime, correct?
Does this happen with all callers or specific contacts?
Do you experience this behavior while you're connected to a cellular or Wi-Fi network?
In the meantime, check out this resource which will show you how to troubleshoot FaceTime: If you can't make or receive a FaceTime call on your iPhone or iPad - Apple Support
"Use a fast connection to avoid sound quality issues with FaceTime
If your cellular connection or Wi-Fi network runs slowly, or other users stream audio or video on the same Wi-Fi network, you might have these issues:
- Connection alerts or unable to connect
- Choppy video calls
- Black screen
- Dropped calls
Make sure that both you and the person that you call use a fast Wi-Fi or cellular connection. If you use Wi-Fi, FaceTime requires a broadband connection."
We look forward to your reply.
Cheers!
