I'm getting what sounds like feedback when talking to people on the phone. This has only started happening since the OS upgrade v.22.214.171.1243. I've done a complete security wipe, supposedly getting everything back to factory settings. I reformated device memory and then I downgraded my OS and then reinstalled the latest version. I'm still getting what I can only describe as a clash of sound when talking to people. If my friend says something and I laugh, the dual sound coming from both ends creates this feedback. The louder the sound, the louder/worse the feedback.
Anyone else having this issue? Is it my phone or is it Verizon? And what can I do to make it stop????
