Hi every1, I'm new here so hopefully I'm posting this in the right place if not maybe a moderator can help me if it's not posted correctly

I've had my tablet for about three and a half years already and only in the last month or two it is randomly taking a screenshot totally by itself. As you can imagine this has really freaks me out since it didn't do it until recently. I don't load or put any apps on my tablet really other than the ones that are already installed on there from the beginning

I looked in the gallery and I can see the screenshot of my screen that it took. This is so freaky especially since I did not do it. I tried clearing my history and my cache,, but it still came back a few days later and started doing this again

Thank you for any help suggestions or advice I would really appreciate it
