Q: alerts not working on iphone6

Greetings lleyn,

Thanks for using the Apple Support Communities!

From your post, it sounds like you are not hearing your iPhone ring or hearing an audible alert. To troubleshoot this situation, I suggest reading over and working through the information in the following article. Be sure to check your Ring/Silent switch to verify your sounds have not been muted as described in step 3. 

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

 Have a great day!
