I also had problems with hearing my phone sometimes, no matter what ringtone I had it set on. If I was at a noisy place, such as Walmart or Kroger, and I had the phone in the bottom of my purse, I would often not have any idea that I was getting a phone call.
Once, I had about 15 missed calls because we were in Walmart, and my husband was trying to locate me. When I found him, he was there with his phone in his hand , still trying to call me.
I went through all of the ringtones, and the one that sounds like a fire truck blasting its horn seemed to be the loudest one, and even that didn’t help if the phone was in the purse.
The buzzer/vibration actually worked better because sometimes I could feel the purse shaking and knew it was the phone.
The answer happened accidentally.
My daughter got a new Apple Watch, and she gave me her old one because it also monitors your heart rate and is a waterproof (swimming proof) fitness tracker, as well as all of the other cool features that it has.
One of the things that it does is to answer the phone.
When you get a call, it shakes on your wrist so that you can always tell that you have a phone call. All I have to do is to tap the watch face, and I am connected with a speaker phone, and can talk with whomever has called me.
If I think it is an automated phone solicitor, then I just put my hand over the face of the watch, and it disconnects the call.
Everything is simple and so easy, and I just love this feature !
I do not have to worry about not hearing the phone, or not being able to answer it when expecting an important call.
