In December, I purchased my third iPhone. This time it was the gorgeous iPhone X. I got the top of the line and purchased the coveted AppleCare coverage. Shortly after my purchase, people started telling me that I sounded muffled and they couldn't hear me at times. Verizon is my carrier and I typically have a strong three to four bars. I also noticed that the "dialer" (when making a call) would freeze up intermittently. The whole phone would lock up and I had to restart the phone. I did some self-diagnostics and used the voice recorder and I could hear myself. Nevertheless, people kept saying that I sounded distant and muffled. I called AppleCare and took the phone into the store and they reinstalled my software and diagnostics indicated no problems. After a week, the problem continued. I'm a diabetic and my phone is my lifeline. I went for a jog and I could feel my glucose dropping. I took some glucose tablets and I could feel it was going to be a rough attack. I went to dial my sister for assistance and the dial screen "locked" up! At that point, my shaking rendered it impossible for me to even hold the phone. Luckily, my glucose started to rise and after 30 minutes, I was strong enough to walk to my car. I called AppleCare and they made another appointment for me to meet with them. They ran diagnostics and it showed everything was functional. They said they would reinstall the software without any Apple Store applications. I asked as to "why?" I was told that it may be a bug. I thought, aren't Apple Store app's were tested to run with the IOS? I know all app's and operating systems have bugs, but when I asked how long I need to wait to add app's, I was told until the problems arises again? What?!? I expect this from an Android phone. They said, they could give me an olde phone for a couple weeks, while they test mine. Am I being unreasonable? No, I cannot make the problems replicate in the store, but why would I lie? Thanks for listening. Maybe I need a flip-phone. Sadly frustrated.
