My Android phone prevents me from recording phone calls at the request of my carrier, even though it's totally legal for me to do so in my jurisdiction.
I'm not loving where this is all going.
The most frustrating part about this "feature" is that you don't know it's enabled until the screenshot is taken and you're left with a picture of nothing.
That and some app authors thinking they're protecting you with this (referring to banking apps in particular)
User hostile UI in the name of security is particularly bad: we are supposed to type unique and complicated passwords in text fields without being able to see what we type, and if we get it wrong, we are put in timeout for two seconds. Citrix Netscaler nowadays apparently wants to be extra secure and shows you the most generic error message if you have a typo in either your password or user name and just tells you to "try again later", so you do until you lock yourself out. It's madness.
