I've noticed some weird behavior on my iPhone 5C. I have the ringer and alert volume set to 100 percent, and Change with Buttons is set to off. The ringer, clock alarm and timer sound at 100 percent volume like they should, but all other alerts such as reminders, text messages, emails, and alerts from third party apps such as Alarmed, sound at whatever volume I have the main sound volume set to, which is usually pretty low. This behavior persists even after several hard resets. I don't think it's supposed to be doing this. Shouldn't all alerts be sounding at 100 percent volume as the ringer, clock alarm and timer do? Is there a way to fix this?
