i restarted my phone last saturday because it is not responding but as i turned on my phone again, some of my apps are missing. but when i check on the memory usage, tho9se missing apps are still there, same with the appstore, where it is indicated as "open" and not the re-install icon. I've tried some of the suggestions that I've read on some sites such as restarting your phone, resetting the home screen layout, and refreshing or checking the restrictions of apps. I've deleted these apps also through general -> usage -> (select app) -> delete app. so that i can just install them again. But when i install them again, they become hidden and inaccessible. Any more suggestions? Thanks alot!
