FAQ

Alarms do not ring

  • Make sure no system restrictions are applied to Sleep as Android: Check our guide here.

  • If the guide won’t help, send us your log using Left ☰ menu → ic help q Support →ic bug Report a bug.

Garmin - Backlight turns on

  • On Garmin watches there is a system-wide gesture backlight setting that will light up your screen on wrist move, when you have any app running. This setting is ON by default.

    1. Go to settings/system/lightning/during activity/gesture and switch it to off. Now the light does not switch on if you are running or cycling and turning your wrist. Check that it’s still on for buttons and alarms so it’ll turn on if you need it during sport.

  • Fenix 6: It may be possible to set a power mode / power profile in the Power manager so that backlight won’t light up in the Sleep app only.

Garmin - Cannot accept start dialog (green tick)

This dialog is the only way to start a watch app from the phone. There’s unfortunately no way to do it without that dialog.

However, there is a bug in Garmin firmware that breaks this dialog on Vivoactive watches.

In that case please don’t start sleep tracking from the phone.
As a workaround, start sleep tracking from the watch (just start the app on watch and it will trigger sleep tracking on the phone).

Garmin - can I get rid of the confirmation dialog at Sleep start?

When initiating sleep tracking from the phone, you have to confirm a dialog on the watch, asking you whether you want to launch Sleep. To initiate connection between the watch and phone, we need to start the Sleep app on watch - however, as designed by Garmin, it is not possible to programmatically start an app on the watch without asking the user for consent.

It seems like a weird decision in the context of sleep tracking. The reason as stated by Garmin is that all ConnectIQ apps are treated as "activities", meaning actual physical activities, and that the watches only allow one app to run at the same time (no multitasking). You wouldn’t want a random app to replace your current activity (say, that’s recording your running in the middle of a marathon) and let you lose your data. Apparently we’re gonna have to live with that :/

Lockscreen does not unlock on alarm

Generally all new Android versions

Google made it impossible to start screens from the background on newer Android versions. This is why we can no longer show the alarm screen with the big buttons under usual settings. The app can just show notifications from the background if the screen is on when the alarm starts. If the screen is locked we usually are able to show the full-screen alarm.

  1. Go to Settings → Alarms → Always fullscreen alarm (might be hidden under Advanced in Snooze/Dismiss section), and enable this option.

  2. It will take you to the system settings, where you need to grant the Draw over other apps permission.

XiaoMi / MIUI

On Xiaomi/MIUI, you need to grant special permission to Sleep as Android so that it may unlock your screen during alarm.

  1. Go to System Settings → Permissions → Advanced Permissions → select Sleep app and give it permission to access Lockscreen.

Note If you are using a Captcha task from the Captcha add-on, please, make sure the permission is granted to the add-on as well.
Samsung

When alarm goes off, it does not disable the lockscreen and you have to manually unlock the device to tap snooze or dismiss.

You may have Sleep as Android enabled under Border lights (Edge Lightning on some versions). This causes the alarm popup to not display over the lockscreen, as the notification is being shown as a light around the edge of the screen.

  1. Disable Border lights for Sleep as Android in your device’s settings.

Samsung Galaxy Gear - Watch app stuck on "Start tracking"

This can be a result of multiple things, so please make sure to do the following troubleshooting:

  1. Make sure you have Sleep as Android Gear Addon installed on your phone

  2. It can happen that the addon cannot be started by us if it was force stopped previously. In that case please go to Play Store app on your phone, open addon page tap on β€œOPEN”.

  3. Opt out of any battery savers that you might have on your phone, for all involved apps (Sleep as Android, Sleep as Android Gear Addon, Samsung Accessory Services) – to find out how to do that, please consult dontkillmyapp.com

  4. Samsung Accessory services sometimes misbehaves and prevents connection to the watch for 3rd party apps. Please uninstall and reinstall it.

Tracking crashes, stops suddenly

If the tracking stops completely after few minutes, the background processes are restricted by your system.

  • Make sure no system restrictions are applied to Sleep as Android, or any companion app for a tracking with wearable: Check our guide here.

  • If the guide won’t help, send us your log using Left ☰ menu → ic help q Support →ic bug Report a bug.

Why is there a red bar / section / block in my sleep graph?

The red block indicates that something went wrong with tracking at that time and the device stopped providing sensor data for some reason. Usually those are some non-standard battery optimizations or battery savers, the battery gets too low so we preserve it for the alarm or connectivity issue if you use a wearable.

1. Battery restrictions

Make sure no system restrictions are applied to Sleep, or any involved apps like wearable companion app).
See our guide here, and follow the instructions.

2. Too low battery

When the battery is too low (usually below 10%), data collecting is terminated to preserve enough battery for alarm.
When the battery was too low, there is a battery icon is displayed on the graph:

low battery
Figure 1. Low battery graph

3. Connectivity issues with a wearable

When the connection with the wearable is lost, you can see red sections on the graph. The app always tries to reach the wearable again.
The graph can look like this:

red wearable
Figure 2. Connection lost during tracking
  1. Opt-out from any battery restrictions is applied by your system (https://dontkillmyapp.com/)

  2. Pair the wearable with your phone in System settings.

  3. Make sure the BT is not lost, and try lowering the distance between the phone and the wearable.

  4. Try settings the device as Trusted device.
