Ever since I got my phone back from repair my notification sound and vibration in the settings menu is very intermittent so my messages notifications dont come through most times. My ringer and vibrate there is fine. I have checked everything I can- DND is off, bluetooth is off, individual app notification settings are all on, volume is high... even reset all settings except factory reset and only solved for a short time. Then after not doing after message sounds will come through. And then they don't again. I've used the *#0*# to go to testing mode and sounds and vibrate works. Any ideas? I even thought it might be a sound file that might be missing
