Hello, apologies if wrong forum. My Samsung Galaxy S4 recently stopped giving out its maximum sound during calls. The other party can hear me quite fine but from my end, I can hear from what it feels like only 10% of the volume. I do raise the volume to 100% during the call but to no avail. Here are a couple things I've noticed: - The volume works as normal for music. - The volume works as normal when placed on speakerphone; the issue is only while having handset on instead of speaker. - Safe Mode did not help. Here are following volume settings: http://i.imgur.com/JuJUHLJ.png http://i.imgur.com/hdg6ByI.png I do have T-Mobile's insurance plan and I am willing to try a factory reset but those two are only last resorts to me. Any help or advice from tech gurus would be greatly appreciated.
