[Q] Morse Code Sound While Charging? topic

My Note 4 (T-Mobile version, obviously) is making a very faint rhythmic beeping sound that almost sounds like Morse Code when I place it on my wireless charging pad. The phone charges just fine and doesn't get hot or anything, but the beeping is very annoying when I try to sleep at night. The beeping stops when I take my phone off the charging pad, but starts again as soon as I put it back on the pad. It still beeps even if I turn the phone off. I am using the official Samsung wireless charging back cover and official Samsung charging pad. Is my phone just transmitting my personal info to the NSA through Morse Code while I sleep?

Thanks,
Jeff
