Speaker Microphone choppy

Anyone having problems with speaker/Microphone issues. When on speaker phone other parties kelp complaining about my voice coming across choppy. I may have a fix after three new replacement phones.

This is my 3rd. Phone. After many hours with apple phone support my problem was elevated to a senior advise who suggested to restore my phone to factor reset. So far so good after restored by apple and not from my iCloud restore.

Obviously the first phone’s software was defective. Therefore every restore from cloud or phone to phone was restoring the same defective software.

so far since the factory restore Speaker Phone choppiness gone. Made several calls using sparkler with no problem. Good luck.
