Samsung Galaxy S3 Tips and Tricks
I have not see tips or tricks on this phone so here it goes
1. To change the shortcuts on the lockscreen head to Settings --> Security --> Lockscreen options and then press on the text that says "Shortcuts" beside the toggle that enables or disables them. You'll be taken to a screen that lets you select which ones you want.
2. Take screen shots by wiping the edge of your hand across the screen... or also take a screenshot by pressing the power button and the home button together.
3. another hidden-away setting in "Languages and inputs" in settings is the voice control for apps settings. That lets you do various things like say "snooze" to snooze your alarm, or capture to take a shot with the camera etc...
4. Go to your phone dial pad > press menu key > call settings > tick "increase volume in pocket"
5. When you open up task manager you can individually 'remove apps' by swiping them off the screen.
please let me know if u find any more
