Why have all my apps been replaced by the green android robot?

[AC Question]

Yesterday morning, I went to text somebody when I noticed all of the apps that you have to download and don't come on your phone already have turned it little green android robots.Even the play store turned into a green robot.I tried opening one of the apps but it said that I didn't have the app installed.When I tried actually texting somebody ,messenging open but a few seconds later it just closed.I click the internet it work,I could still call people but I had no idea why I couldn't message and why my apps "weren't installed".

Welcome to the forums. What phone do you have and what android version is it running? Does the problem persist after a reboot? Do you have an SD card mounted on your phone?
