Volume drops to zero with TuneIn App
A couple of months ago my S4 started to drop the volume to zero with the TuneIn app. I'll be listening to a radio station and the volume randomly changes down to zero. I'll adjust it back up and it just slides right on back to zero. At times it moves up and down. I can watch the on screen slider moving. This is usually when I'm out training, so I also have RunKeeper on too.
I've reset the phone to try solving the issue but it has continued. Any ideas? US Cellular S4. Only a few months old.
Thanks. Oh and I did try a third party volume app and that did the same.
