So this just happened randomly this morning. When I restarted my phone it said "Optimizing Apps 1 out of 1" so I decided to fix that issue by uninstalling the app that was using the most battery space. (This is a solution I saw on another forum site) After doing so, the problem still persisted so I uninstalled almost all the apps on my phone and then the problem was solved. I go to open Google Play and it closes automatically. No *Google Play has stopped message* it just closes. Sometimes it'll open but when I go to reinstall an app it closes as soon as I hit the install button. Now I don't know what to do, I've cleared up a lot of my phone storage but my phone continues to bug out. I can't even open my gallery, every time I do I'm met with a black screen.
