I have been using iOS 12.4 final version for years. I was very pleased. I wanted to try the new iOS version and updated my phone. My phone is iPhone 8 plus. Currently available iOS version is 16.6.41. Unfortunately, it is not possible to downgrade the iOS version officially. The new version makes me feel like my phone is slowing down, but there was no trace of slowness in the old version I was using, it was still performing as it did when I first bought it. I want to return my phone to iOS 12.4, is there any way to do this? If there is, how to do it? (Please do not give me answers such as why do you want to roll back, the new version is better, more secure, there are security vulnerabilities in the old version.) I just want, That's enough
