I acquired a refurbished Xperia XA2 dual SIM (H4113). As per the installation instructions (https://jolla.com/sailfishx-linux-instructions-xa2/), I toyed around with Android to ensure that everything works alright. Yet, if I record a video (no matter what FPS setting or resolution), during playback there is a distinct high pitched noise over the full length of the video. I'd say it's comparable to what a built-in microphone in a laptop pics up, if a fan is spinning. Before going ahead to flash Sailfish X, I wanted to rule out that it's a hardware issue, that I need to send the phone back for. Did anyone here experience the same issue, when still running Android?

EDIT: According to zuyev's answer I recorded a number of short audio sequences using https://f-droid.org/en/packages/com.github.axet.audiorecorder/, as I only have the F-Droid repositories available. In Audio Recorder the only settings I changed, were the Sample Rate and Mode, which are reflected in the file names.

Also, to clarify: I am still running the Android the XA2 came with. I did test recordings before and after applying the latest OTA updates. (No changes in audio quality.)

The high pitched noise, to my ears, is only noticeable in the stereo recordings.

With the help of zuyev and a local friend, who's into electrical engineering, I declared it a hardware issue and returned the phone.

Thanks for your efforts! :) I updated my question to include some recordings of the same ringtone.
