I have Moto E (2nd Generation Android version 5.0.2) .I use power ON/OFF button to lock the smartphone phone or to go into the sleep mode. Due to frequent use of power ON button, the switch is not working properly.It needs to press it long and hard.
So are there other options available except power button
1.To lock the smartphone
2.To make smartphone go into sleep mode. and
3.To turn ON the smartphone.
