W Owens, first thank you for reading what works for me. Today I made one more modification... I turned off the vibration feature. I don't live in a Earthquake or Tsunami area, if I did, by the time one hit, it would be over.
I am 100% positive the problem is in the case, I thought I had found one pretty darn close to what I believe will fix the sound and heat problem, nope. I ended up also cutting out the flap where the charge cord goes in, the cover isn't necessary, again the phone is built resistant to the elements.
I also cut the parts out on the case I recommended I am using, it's where the holes I offered to drill out. More air, less echo, less heat.
Pods are great to escape, unfortunately, I have some and on the airplane I had to keep popping them out to hear anyone talking to me or be understand. I kinda get urked when someone is on their pods and don;t realize I can hear their conversation, folks tend to talk out loud.
I'm sure my post stated, if not here it goes, this is a problem for every smart phone using a case. Even the new Apple 14... same phone... same cases... more expensive... better camera lens.
I don't depend on luck hmm... something far greater than me and higher up.
