Sleep as Android Q&A
1

Hi.
I used the app for 3 days and i realized my deep sleep percentage isn’t normal (80%/95%) , i tried both sonar and accelometer

  • I have a question ; will sonar work normal if i sleep with a blanket?

Hi @Ayoub, sonar will work with a blanket.
But this sounds like the sonar signal might be too weak to properly read your movements.
Where do you keep the phone?
What is the signal strength in Settings > Sleep tracking > Test sensor?
