LOL, I had little flip phones for years ... then my techie husband decided to get us the so-called "smart phones" when they first came out. I don't use a mobile phone very often, half the time I forget to take it with me when I go somewhere. I have a heck of a time swiping the screen on my smart phone to answer a call ... I always seem to disconnect and have to call them back. Hubby told me that I just needed to use the phone for awhile and play around with it and that I'd figure it out.
Well ... a few years ago my best friend and I flew out to Waco Texas to go to the grand opening of the Silo's (from the HGTV show, "Fixer Upper"). Our return flight to Dallas was delayed and then the flight from Dallas to Orlando was delayed so while my friend got some work done on her laptop, I decided to play around and learn stuff about my phone. I managed to get to my Facebook Page successfully and posted a photo I'd taken but evidently while clicking buttons and looking at settings and other stuff, I opened a bunch of Apps.
When our bill came in the next month, there were tons of charges for music and other apps that I had apparently opened but I have no clue about how I did it. My husband called our service provider and talked to someone and probably explained that his wife was old and blonde ... luckily they didn't make me pay for all that stuff.
I had all of the "special" stuff taken off my phone; no internet, no Apps, no texting (which I don't really understand anyway!) I still have the danged smart phone and still can't seem to swipe the screen to answer a call.
Smart Keys on computers??? I wonder if my laptop has smart keys.
I've entered the degree symbol at times and I didn't realize there was a problem with the system recognizing it ... I just figured in these instances it was something to do with the computer of the member who entered the data.
