When your apps shake and rattle on your iPad's home screen, they transform into nimble icons that you can rearrange, relocate, reorganise into folders or delete. When you're done revamping your home screen, pressing the "Home" button should stop your apps from shaking so that you can resume working or playing on your device. Occasionally, however, your "Home" button may let you down, but you can resort to a few quick fixes in such instances.
Press the round "Home" button right below your iPad's display of jiggly apps. This should tranquillise your apps immediately. Stop here if it works.
Press the "Sleep/Wake" button on your iPad's top-right edge to turn your screen black. Press the "Sleep/Wake" button again to revive a display, but this time of calm and sedate apps. Stop here if it works.
Restart your device to release it from the possible grip of a corrupt app that's making your other apps shake. Press and hold the "Sleep/Wake" button, then drag the power-off slider to the right. Wait a few minutes for your iPad to cycle down and turn off, then press the "Sleep/Wake" button again until the Apple logo appears. Drag the slider to the right to power back up.
Reset your iPad if it refuses to shut down. Press and hold the "Sleep/Wake" button and the round "Home" button simultaneously until the Apple logo appears, roughly 10 seconds later. Wait a few minutes for your iPad to reset itself. When your home screen reappears, you should see no hint of shakiness among your apps.
If your iPad's "Home" button frequently fails to stop your apps from shaking, you may have a faulty button. Take your iPad to the nearest Apple Store for diagnosis and repair.
