I am at whits end here trying to figure out this problem. I'll Start off with a few notes
Account age (4-5 years) PREPAID
Account has had just 1 phone line for the Majority of that 4-5 years.
Added a NEW line to my account for a total of (2) lines on ONE prepaid account.
I have NEVER had a single issue with call quality or service with this account.
My wife uses the SECOND line on the account, We purchased a USED Galaxy S7 in pristine condition.
We both live in an area where we both get 3-4 out of 5 bars constantly. So it's not an issue of service.
Now here's the wierd part. On the S7 device if she uses speaker phone ANYONE she calls or calls hear CAN NOT hear her it's constantly distorted or breaking up.
We fought this for 8 months and couldn't take it anymore, so we purchased a Galaxy S9 after we were told there HAD to be a hardware issue with the speaker on the S7.
Here we are 3 days after activating the S9 and it's doing the EXACT same thing the S7 was doing. Phone works when you hold it up to your ear, but once it's put on speaker it's an IMMEDIATE drop of quality in the audio. There is NO WAY this is a coincidence with 2 different devices manufactured YEARS apart. This has to be a setting issue with that particular phone line or a setting in general.
I want to add that BOTH the S7 and the S9 were factory reset and updated prior to use.
PLEASE HELP!!! HOW CAN WE FIX THIS PROBLEM!!!
