Every so often I will unlock my phone and notice an Icon is missing on my home screen. Upon further investigation it seems that I can always find it on the home screen to the left or right. My question is: how does this happen? I have tried everything I could possibly think of to reproduce moving the icon from screen to screen. It doesn't pertain to a particular icon or icon position, it can happen with any of them. Until recently I thought this didn't affect widgets but I noticed it happen with the Google search bar... It's not that big of a deal because I can quickly delete the icon and put a new one on the proper home screen. I just want to understand how this is happening, it has been going on long enough and frequently enough to make think it is not the phone but something I am doing. I have replaced my original DROID 3 times since I got it and have seen this problem since 2.0 on my the original one.
It's possible that you're long-pressing the icon and then sliding it over to the other screen. This is also how you could put it back where you want it without deleting and re-adding the icon/widget. Several times I've inadvertantly rested a finger on the keyboard long enough to bring up the menu.
