My graphs are flat
There can be several reasons why your graphs are flat.
The actigraphy is almost flat
When you can see some movement on the actigraphy, but the graph is unusually flat:
. Sonar - make sure the signal is strong enough by keeping sonar volume at max at Settings → Sleep tracking → Test sensor → blue sliding bar.
- you can also try different frequency by choosing other frequency from the ddrop down menu list in Settings → Sleep tracking → Test sensor → Frequency
- keep the phone closer to you bed
- try different positioning of the phone
. Accelerometer - try keeping the phone closer to you.
The actigraphy is flat, or red
