TC56 - No illumination/decode when suspended for 10 secs on battery power



I have updated the TC56 device to the latest firmware "Android M GA 01-16-08.1-MG (GMS)" but I am still getting an issue when the device is suspended for more than 10 seconds, the scanner doesn't work (no illumination/decoding, only the red spot).


In the changelog I can see that this issue should have been solved :


"SPR-31875 – Provided fix for EMDK scan service application when suspended for 10 secs on battery power, no illumination and decode afterwards"


What am I doing wrong ? Can you help me getting this working please ?
