Sony SP randomly blinking and letting out an alarm tone

[HomerSimpson1]

I activated my phone today ( Some singtel plan ) and then at night, it started to flash a blue light, and kept on emiting an alarm tone. I checked the pull-down control center and there were no notifications. Whatsapp, Alarm, Facebook, Gmail... All nothing.

Even when i offed the Accent Light in Settings and turned down the volume to mute, it still flashed and kept on vibrating.

Hence, i shut down and booted up the phone. 30 Minutes later, same problem..

What in the world is wrong with my phone? Am i entilted to another one?

Restore it to factory defaults

Do you have NFC enabled on your device and is it in close proximity to an NFC enabled card?
