What time did you go to bed last night? Your phone knows.

Who do you chat with the most? Your phone knows.
What illnesses have you searched for? Your phone knows.
The photos you've deleted, your phone also knows.
Where you've been, how much you've spent, what songs you love to listen to, whose Moments you've looked at late at night—your phone knows everything.
One day, your phone spoke up: "Actually, you're not that happy."
You were startled.
