yes this happens to me randomly. when it does happen, it'll pretty much happen every morning for days. i toggle airplane mode a few times. happens on stock too.
hasn't happened in a few weeks for me.
this phone does a lot of weird things. this current triumph, when I first got it, wouldn't play music in loud mode at all for the first few weeks. that's why i thought it didn't have the notification glitch. but now it's back to "normal" for what the triumph is "supposed" to do
weirdest yet, i got this strange ringer while the phone was in my pocket. haven't checked to see if it's a stock ringtone. hit the power button, screen turned on, it stopped ringing. no idea where it came from. I'm sure it's some app I have, but I've never heard it before, and have no notification of it. And it rang for a good 20 seconds too, since I was waiting to see if the screen would light.
