Recently, we were using the suspend option by searching option through the “Activities” menu. We were looking for alternatives for scenarios where we would not like to use a keyboard (e.g. on a touch-enabled screen). After some quick testing we saw that when you long press the power button it turns into a Suspend button!!
In this video we can see that if you long press the power off button in the top right menu it will convert to the “Suspend” option!
