Screen unlock beep

[Edgie70]

Hi all , in the settings I have the  screen unlock sound off but I've been getting a random beep when I unlock the screen , anyone else have this irritating issue

My note 8 was making noise every 3-5 seconds, as soon as screen is turned off. I could hear the speaker is active and repeated notification-like noise every 3-5 sec. NFC was not the problem. couldn't recreate it on safe mode. 
After some investigations and turning apps on & off, it was from Haylou App. I used it for pairing haylou T9 bluetooth TWS. so force stopping that app solved my problem.
