What is wrong with my phone: shutting off, missing apps, and just overall weird things?

My phone (a Samsung Galaxy s4) suddenly turned off when I was using it, and when I turned it back on, it showed that I had no apps and 1%. It then shut off again and I wasn't able to turn it back on. After finally hooking up my phone to a charger, it turned on normally (except for the fact it said 0%). I noticed some of my apps were missing so I tried downloading them again only to get a popup saying it was unable to download it. My phone was fine before all this.

Welcome to the forums. I would let it charge for a couple hours before trying to turn it on. After that, you may need to consider doing a cache clear in settings>storage. That may clear up some space on your phone to re download your apps.

Did you get an update for the OS recently?
