What apps is everyone experiencing this with? I use WhatsApp and it's plenty loud. My email notifications are plenty loud. Text notifications are a little too low. And the ringer volume starts low but then goes up to normal range. I'm not sure if I'm not experiencing this issue or if there's something else going on. I remember the security update that caused this, and the only thing I noticed was the text notification volume became lower, but nothing with any other app as far as I can tell.
