I am using a secondary user profile for my everyday business.
However, in a secondary user profile the force checkin via dialing *#*#CHECKIN#*#* does not work. It is just ignored, probably due to permission issues.
Can you add a button in the UI that does the same thing?

As a workaround I used the following ADB commands:

adb root
adb shell am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://2432546 --receiver-include-background
