I tried this:
B4X: 
Dim PhoneId As PhoneId
Dim PE As PhoneEvents
PE.InitializeWithPhoneState("PE", PhoneId)

Sub PE_ScreenOff (Intent As Intent)
    Log("Screen is OFF")
End Sub

Sub PE_ScreenOn (Intent As Intent)
    Log("Screen is ON")
End Sub

But PE_ScreenOn is raised even when the screen is turned off!

Thanks LucaMs. It works ..but once you put the screen on again for the second time, it doesn't work!
