At first I thought it was the case because it had no holes at the bottom, so it was covering the speaker and mic, but even without it there would be an echo. So I took my phone during the week of purchase to T-Mobile and the manager was not helpful at all. He kept telling me it’s normal, it happens sometimes, it’s a network problem, the phone is not defective. But he told me my only options were to send it to Apple or Get a different one with my insurance. He didn’t even try to help, nor touched my phone at all!
The closest Apple store to my town is 2 hrs away, so I took it to the Geek Squad at Best Buy instead. They checked my phone and even though I saw the screen showed “issues found” they said the phone was working properly, but they could send it out to Apple to have it checked and it would take about a week. I work from my phone, so I can’t afford to be without it for a week. It was very frustrating because until this day, there is no solution to this problem online.
I finally visited an Apple Store and thank God the associate knew what he was doing! He took my phone for a few minutes, came back and told me there were no problems with the device, but he had me reset my network settings. IT FIXED THE ISSUE! I can’t believe it was that simple and no one could help me before. I almost purchased a new phone.
It has been months since that day and just a few days ago the echo came back, but it went away by resetting the network settings again.
Before you waste more money on another phone or your time waiting for them to fix your phone, TRY RESETTING YOUR NETWORK SETTINGS.
