Hey,
Have you also a werid noise if you Press your ear near the fingerprint Sensor?
I noticed this today for my x720>>>

Not at all

Not once before but I do hear a slight sound like a CPU fan noise when I press my ear against it just now. I remember this was happening with iPhones too, didn't turn out to be anything bad except they have a mic near it that feeding it into videos. It was coming from the same place where our FP sensor is on them.

It seems to go off when the screen is off... Hmm. Odd.

Yeah maybe, but for me the sound ist a bit scratchy. Perhaps it ist only the Prozessor witch ist making this noise.

I hear a noise when I shake my device. It comes from the camera. Any clues??

Isn't it coil whine? Noticeable on heavy usage of CPU, heard max 5 cm. I hear it too.

Ive detected that sound before. But this time it is when I shake my device it sounds like volume or on/off buttons are moving except it is not the buttons because I'm holding them.

My x722 also has this issue, and the noise is bigger when the phone is under load, do you think it could be a sign of a big defect?

i received my 722 and i CAN HEAR the coil whine
wow the 1st time i can see a coil whine coming from a phone..... i think it is consuming my battery because it does not last so much even in standby whithout sim, without so much apps installed...... and yes i hear it bigger noise when benchmarking in thinks like pcmark or antutu
