So i have had my phone for awhile and i already have apps downloaded from the play store, but i just realized that i can no longer find it on my phone. Ive tried looking for it in all my settings, and searched my phone. Ive also tried to update my phone to see if that was the problem. My apps are crashing because it needs updates and i don't know what to do. Im trying to re install the app but i don't know how.
