IPad Pro 2018 - weird sounds
Lately I've noticed that my iPad Pro 2018 model started to make this strange buzzing/crackling sound however the sound is very minimal so I don't mind it. But I'm concerned for the health of this device and was wondering if this will become a problem in the future where this iPad will not be usable. I'm not really interested in getting it checked (don't really know how to) so a direct answer would be much appreciated.
Thanks
iPad Pro, iPadOS 15
