What is this? My phone started last night to ask "Permission" to allow several function's to work. And I found nowhere how to allow this. My phone worked fine since I have had it since Jan. of 2016. Now I cannot save pictures, get certain new apps to gain permission to utilize certain settings on my phone, etc. This makes the phone useless! And when you search for how to disable or gain permission the explanations and diagrams do not match what appears in the settings of the phone. Does anyone have a simple means to allow me to get permission again?
