This works on almost all Galaxy phones or tabs, including Galaxy S6, Galaxy S5, Galaxy S4, Galaxy S4 Active, Galaxy Note 2, Galaxy Note 3, Galaxy Note 4, Galaxy Note 5, Galaxy Mega 6.3, Galaxy Tab 3 Pro, Galaxy S4 Mini, and Galaxy S3.
1. Press and hold the Power and Home buttons together.
2. Hold them tight until a shutter sound is heard or you see a visual indicating a picture was taken.
3. It is a little tricky that you need to hold the Power button slightly before pressing the Home button, and then hold them both down.
