Whenever I am making a phone call on my Galaxy S8+ I will hit the send or call button and it takes about 15 seconds for the first ring. I had to make a 911 call a few nights ago and it took 15 seconds before the first ring. This is not acceptable!! Any suggestions? I have been on the phone with tech support several times but can not seem to get this solved. I have the Newest software updates and got one last night. It was a 100 meg update. Thanks in advance for any help.
