My phone keeps making a notification sound and vibrates when there's no notification. It's not a sound I have set to any of my notifications and I can't find the sound in settings. It's even doing it when my phone is in do not disturb so is waking me up in the night. Anyone else having this problem?
Your charging cable is bad, or your outlet is worn out or loose fitting to the plug or something. That's the sound and visual effect for when you plug in your phone. The cable is bad so in the middle of the night when it blips, it'll make that noise supposedly without anything happening
