I've noticed lately that some apps will temporarily disappear from my app drawer. For instance, I could not find Angry Birds in my app drawer. I went into my settings to manage my apps and is was not on that list either. I had recently had Angry Birds open so I did the long press on the home screen and selected it from the recently used apps. Sure enough, it started right up and worked fine. I checked the app drawer and it was back to where it should be. This has been happening often now, few times a day maybe. Anyone experience this yet or know how to rectify the issue?
