No scheduled scan [SOLVED]

Since a couple of days there is a possibility to plan scans in AMS 5.
On all my devices it works fine except on my Samsung Galaxy Tab 3. The ON-switch is grey and doesn’t react.
What’s going wrong?

Seems a compatibility problem with the Blue light filter app.
If that app is switched off AMS works fine.
