I just installed OS 26.1 on my iPhone SE from 2020. Aside from the visual changes (which I do not care for but perhaps can adapt to) I have loss the ability to quickly block spam callers; this is a big deal for me. Can I downgrade my iPhone SE from iOS 26.1 back to my previous OS 18.x ?
iPhone SE (2nd generation)
No, Apple has never supported downgrading iOS.
Sorry, downgrading the operating system is not supported.
Don't forget that the Block Caller feature is really only effective in blocking legitimate numbers. Spammers use "spoofed" numbers, so any further communication is not likely to even come from that number again where blocking would stop them. I have seen some devices filled with blocked numbers thinking that they are reducing spam, but all they have done is filled their phone with a bunch of random numbers and haven't actually reduced spam calls at all.
For reducing spam, I would first contact your carrier where they have the ability to verify the number before it even reaches your device and you can choose what action you want to take. Notice I said reduce spam because there is no way to eliminate them unless you only allow calls from the people you know.
Thank you.
I am aware of spoofing but I suppose my definition of spam is overly broad e.g. when serving as executor/personal representative, or even being a family member, of a decedent you receive quite a few of unsolicited calls from "legitimate" companies offering a wide range of services.
Thank you
