I THINK MY TABLET JUST DID THAT LIKE, WHISTLE NOTIFICATION AND IT SCARED AND WAS SUPER LOUD.

I AM INSANELY STARTLED RIGHT NOW, CUZ I WAS IN THE MIDDLE OF READING SOMETHING AND THE WEIRD PART WAS, THAT THE CHARACTER HAD JUST GOTTEN A TEXT AND I'M TRIPPING OUT, MAN.

I DON'T EVEN HAVE ANY NOTIFICATIONS SET TO THAT TONE.

Update:

....I just realized it was my Wattpad notification center. Smart Twix.
