what's a hard restart? turning phone off then restart? yes if that's it yes I did
it's set to make my text ringtone twice
I have the latest software update 8.3
what else can I do and thank you for helping
Hard restart is holding the power and home button down for 10sec. while the phone is put into a forced power down (instead of the normal power down using just the power button). Sometimes a hard restart will clear out things normal restarts won't.
If you've done that, you have a couple of options...you can try a restore via iTunes (make sure you have a recent backup), or take it to Apple for a repair/replacement (again, make sure you have a recent backup).
You could also try setting your text message alert to another set number, save it and power the phone down, then go back and set it to 2 again, and see if it knocks it back in order.
I have mine set to do the same thing, and have no problems with it.
