iphone 5S no text alert sound
I set my Sound for being alerted to incoming text messages on my phone 5s. It worked on the first message I received. It has not worked since. I have changed the sound several times and each time it works on the first message I receive but is silent on all further texts. Why do so many of my friends with iPhones have to complain for the same reason about text alert sounds? In the past I had Samsung Galaxies: Everything worked on a Samsung. Something always goes wrong with an Apple and that should not be so. I love Apple but why doesn't the text alert sound work. I miss so many messages: you can't keep looking at your phone all the time to see if a text has arrived.
