I have a sim free galaxy s4 on Vodafone and updated to 4.3 yesterday.
Since today I've noticed that exactly every 5 minutes without fail I get a message notification sound. I don't actually get a notification of any sort but I keep getting that message sound. If my phone is on silent then it vibrates like I have a message.
It took a while to figure out why my phone was randomly vibrating in my pocket or sounding message notification while it was placed beside me but after an hour of constant observation, I've finally managed to pin it down to the fact that it is just making the sound exactly when the clock turns to multiples of five and also it is in 5, 10, 15, 20 etc not other random times. .. .
Does anyone else have this problem? This is not only a weird problem but is getting extremely annoying.
