Not sure if this belongs under Samsung, Android or Verizon, but here we go: The setup: Device: Samsung S4 Mini Carrier: Verizon Android version: 4.4.2 Kit Kat All was well until yesterday, then I found that text message alerts were not working properly. Using the default messaging app, it no longer vibrates when I receive a message, and the notification tone does not play all the way through. It is not consistent in how far it plays before being cut off. What I've tried: Checked and rechecked all of the settings, including blocking mode and the volume sliders. There are no issues there. Deleted all messages. Tried a different tone, one of the built-in ones. Force stop, clear cache and data, restart, reboot, etc. Tried several other messaging apps. All had problems. Some had the same issue; some vibrated, but no sound at all; some played the full tone, but didn't vibrate. I'm currently using Verizon Messenger, because that one vibrates and plays most of the tone, but even it is not consistent in whether or not it plays the full tone. What had changed: The day before this started, I installed a custom alert tone. It worked fine for the first day, and then this started the following day. Just to be sure, I completely removed the clip from the phone and went back to a default tone. I've never had any other non-standard alert tones on the phone. Immediately before I noticed this, I installed an update of Soundabout, which could easily have affected this. But I don't see complaints from other Soundabout users, and completely disabling Soundabout didn't help. Any ideas?
