I believe this is an old one: I’m using a Galaxy S8+ that is reported as “supported” in the Sonar device list, but I get the chirping recorded all the night long.
Where am I wrong?
I’m unsing version Beta 20190906
I’m using 20190910 (beta) and I have the same issue. Have been using SAA on my S7 as well as my current S9
I feel like it’s a side effect that isn’t hard to cure
Hello, is the sonar chirping audible when you start tracking, or it only gets recorded?
Only recorded
We have this reported, but it is device specific. Vendors tent to enhance the audio experience apply filters to speakers or mic which break sonar. Lately, we have many reports solely from Samsung devices
Could you please try different frequency? Some phones have troubles with the dynamic one (F18-20), but work well with others. Please, go to Settings -> Sleep tracking -> Test sensor and choose different frequency from the drop down menu list. From our users feedback, seems like the best frequency for Samsung is F18.
If you find the least affected frequency, you could try increasing the recording threshold a bit in Settings -> Sleep noise recording -> Recording volume threshold.
And we have also discovered just few days ago, that this exact issue can be solved by different positioning of the phone - if the bottom of the phone (where mic and speaker are) is not touching any surface, the chirping artefacts are gone. So try to put the phone on a book or something similar with the bottom of the phone over the edge.
Please, let me know, if that helped.

The last thing is interesting and simple: I’ll try at the next occasion.
On my Galaxy S8, switching frequency from F18-20 to F20 (or any other static frequency) solves the sound recording and snore detection, but I cannot get any good sensitivity this way (the records show more than 95% deep sleep, this is not right).
These phones have stereo microphones, can you not only use audio from the other channel when recording? Or this noise is a result of some internal crosstalk, and both channels are equally affected?
I have the same issue on my Samsung Galaxy S7. I will try changing to a static frequency and see how it goes.
I also experience these chirping artefacts on my Doogee brand phone.
After trying different frequencies, the chirping was different, but always present.
Sorry about that. I don’t think we can do much some vendors simply low pass the input from the mic… so sonar gets into the hearable spectrum :(…
Thanks for the quick reply! It’s always interesting getting glimpses of what goes on in the hardware.
Eventually I’ll upgrade and it’ll probably become moot, but it’s a still a good thing to be aware of.
Since it has been over 8 months since this was discussed, I wanted to revisit to see if there was any new developments. I recently purchased the premium subscription and I tested the sonar sensor using each of the frequencies - and hung the bottom of the phone off a book - and found the noise was present in the sound recordings every time. I have a Samsung S10+. It seems the Samsungs have had this same issue a lot. Anything else I should try? If this doesn’t go away (and we do want the sound recordings) my assumption is I would need to switch to accelerometer (assuming I didn’t want to purchase the infrared light). Is that correct? - Thanks!

Hello, my phone is Oneplus 6t. Any suggestions on suitable frequencies to avoid those annoying chirping sounds? Thank you.
Hello @DimkoRodyk ,
we have this reported, but it is device specific. Vendors tent to enhance the audio experience apply filters to speakers or mic which pushes sonar in recording to a lower spectrum where it is hearable.
You can also try to play with the various sonar settings when you do sensor test… there is F18-22 (Default) but also F18, F19, F20 and try to set signal strength a bit lower. Maybe you can find a combination of settings which works well on your phone?
And is this still reported? Pixel 7 and Pixel 7 Pro have the whining sound in the background of every recording.
Hello @Harry_Barnes … can you try to decrease signal strength for sonar alternatively you can choose different frequencies for sonar which do not cause this issue… In the Settings > Sleep Tracking use the “Test sensor” option… there you can adjust Sonar settings… did that help?
Hi, is it audible during the tracking, or only when replaying the sound files?
