I looked at some of these settings and in my opinion turning off some of these settings will remove some of the functionality of the phone. For the die hard geek they will know the work arounds but for the average joe they won’t know how to get by without some of those functions turned off, like the backup to google drives, most folks aren’t going to know how to backup pictures and text messages on their own. or encrypting the phone, if you forget your password you’re not going to be able to get that data off the phone when moving to a new phone.
