I expect honesty
And you got it. You asked how....(rather than asking if it was possible).....to downgrade the iOS version. We answered correctly and honestly.
Then you asked "how to get out of this".....meaning how do you get out of iOS 26?.....
Well, if you cannot downgrade iOS26.....then obviously you cannot get out of it, can you?
Since you did not ask for any help on any specific issues with iOS 26, it was obvious to me that you had already made up your mind to "get out of it" by asking if you should switch to another brand.
Yes you should, if you have already made up your mind.
If you have now changed your mind about getting out of it, do you want some help to try to address the issues that you see with iOS 26? If so, what are they?
Frankly, I think you have already made up your mind, but I am wrong sometimes.
