I updated my 15 Pro to 17.6.1 about a week ago. I started to notice some things. It started with videos on Facebook, X, and Instagram being glitchy and buffering. I originally thought it was my connection. Turns out it was not my Wi-Fi or connections at all. I could replicate the issues at various locations.
My issues are:
• any video (downloaded, photos, or social media) do not play.
• music does not play
• videos online also do not play. We tried the YouTube and Apple webpages; nothing worked.
• I can make and connect a phone call. That call does not have any audio. Facetime calls also do not have audio or video.
• My battery was hot while charging in my car on Saturday.
After several hours on Saturday with Apple support (first text chat, then phone support), I was left with a phone that didn't work well. Apple phone support tried to reset to factory settings from a computer on Saturday (connected via cable). That reset failed. I then scheduled in-person support though the Apple Support app at a local Best Buy. Best Buy ran all the same diagnostics that the Phone Support did the day before; found nothing. Best Buy hard reset my phone to factory new; same issues (no video or calls). Later on Sunday afternoon, I reopened my case and spoke to a Apple Support Manager for 2.5 hours. She ran diagnostics, attempted to reset the phone again, and tried everything possible. The phone was still quirky with the same issues. She did say that "maybe it's Verizon" and I should speak to the also. The Apple Support Manager ended the call with sending report logs to Apple Engineering to review. The Engineering review could take 3-5 days. Grrr.
I did call Verizon and review all the settings. My Verizon settings were all perfectly fine.
Now I wait for several days until Apple Support gets the Engineering review of my phone's issues.
