Comment 14 for bug 996489

On Linaro Android build:

https://android-build.linaro.org/builds/~linaro-android/origen-jb-gcc47-samsunglt-stable-blob/#build=5

The screen turns to black (background light is still ON) after reached the suspend time interval - 15 seconds, but after waiting for around 10 seconds more, the LCD lights up and main screen shows again.
