"iOS 26 and iPhone 13 I am in my 80s and not very adept with high tech. I have an iPhone 13. I recently installed IOS 26 and 2 updates on my phone. On each occasion my phone settings i.e ringer, vibration etc got wiped out. I missed an important call from my doctor because of this and I am sure my doctor thought I was offering a lame excuse when I told him what happened. Now I am being urged to upgrade to 26.3 and am certain that if I do I will suffer the same fate. Do the folks at Apple not do thorough testing before they launch new software?? MSACPACA."
