Help annoying beeping noise

[kkakes23]

Hi there my mom's galaxy s6 edge just started making this beeping sound. It does it 2-3 every 30 seconds or so, and when she goes into anything it beeps like crazy. We tried turning off the sound, and when it goes to beep it turns it back up. We tried turing off the NFC and that didn't help.

Thanks in advance.
