Being that the person using Snapchat has a different carrier. There is a slight delay. This is what I was explaining to you before. It's not your phone
@Mia13 Please accept my answer as "Accepted Solution" if you have found my explanation to your question to be satisfactoy. I hope that I have assured you that your phone is working within normal operating parameters. Thank you!
***We like to think that our communications are instantaneous. However, most of the time we don't perceive that there is any delay. However, as can be demonstrated, and replicated. When both caller's are using Speakerphone, and are on Different Carrier Networks. There will be an Echo Effect. We're talking mere Milliseconds here.
Usually it's not an issue because usually we can't hear the other party's phone. But it does happen. It's not your phone or the other caller's phone. This is normal.
You can even replicate this effect for yourself by having two phones. Call one phone and answer the call. Hold both phones to your ears. You will hear the Echo Effect in one of the phones. (In this instance even if both phones are on the same Carrier Network) I have done this myself. I hope that my detailed explanation will help many people who have encountered this.***
****This tip will also alleviate the effect as well: Turn Mono Audio ON! This SOMETIMES works***
Mono Audio Sets the Sound Output of your Phone to Output the Sound from only one Speaker instead of both speakers. Technically this isn't something that a user should have to do. But in some cases it will fix the echo. Not always though!
