Buy iPhone big mistake

Excuse my English.

In Greece where I live the apple service is terrible and you can't find a solution.

After using android for 15+ years I decided to switch to iphone (iOS) and got the shock of my life.

The obvious settings that exist on android on iOS do not exist.

For example I have a lot of trouble with the keyboard keys, because it has small keys, I almost can't type text. The settings from "Accessibility" (I'm considered rather handicapped) to enlarge text (I don't know if it also enlarges the keyboard) spoil texts in apps e.g. in X).

Also in Greek it doesn't give the possibility to change the layout and I am forced to use Google's gboard or Microsoft's SwiftKey.

Also in Adobe Acrobat the list of files in the cloud is flickering. https://www.youtube.com/shorts/Z3s-XpswXe4

...and the service for printing https://youtube.com/shorts/-3w8-ycR-dc?si=JpJ0mQTeGOaX6DA8

Incredibly stupid problems!
