Hi guys, Today when I picked up my iPad (which had been open but unused for a day), there was a sound file - with sound controls to play it - on my locked screen, where my notifications usually appear. It's the first time I was seeing this. I pushed the play button and it started to play a sound file that I do not have on my computer (actually, it's a sound file that I had never heard before). I stopped after a few seconds, and unlocked my iPad. I looked for the file, but I couldn't find it on my iPad. It had not been sent to me, and I couldn't find it open in any of my app. What could it be? Now I'm a bit afraid that this might have been a kind of malware... Would that be possible? I'm sorry if my question sounds ridiculous, but I've searched over the web for any kind of explanation, and I couldn't find any... Thanks in advance.
