My cell phone recently ran an update and I’m having some major issues all of my apps and have lost all of photos, videos and documents. I’m not 100% certain that it’s a result of the update, because the phone’s calling and texting functions appear to be working perfectly. As near as I can remember, I didn’t try to use any apps for a day or two after the update. So, it's possible that it doesn't have anything to do with the update. The first time I tried to use an app, Netflix, the frame of the Netfilx app opened with only black space in the middle with an error message that said, “Could not load data”. I clicked OK and closed Netflix. When the Apps screen from which Netflix was launched reappeared, an error message popped up that said, “Unfortunately, the process com.google.process.gapps has stopped.” When I clicked on the OK button, an error message pooped up that said, “Unfortunately, Google Play Store has stopped.” I closed that and held the home button down to see if the play store app was even open. Even though I hadn’t had the it open in at least a month, it was open. So, I closed all apps from that screen and, when I went back to the Apps screen where you launch apps. Before I opened anything, I got an error message that said “Unfortunately, CBS Sports has stopped.” I closed that and held the home button down and it showed that no apps at all were running. None of my apps are working. Error messages are popping up, seemingly at random, telling me that “Unfortunately, ____ has stopped.” When I click on OK, most times another message comes up that tells me that some other app that isn’t running has stopped. The calling and texting features appear to be fine. The only weird issue with the “phone” functions is that, when a call comes in, the error message “Unfortunately, Google Play Store has stopped.” pops up and I have to hit OK before I can answer the call. My Google email account seems to be good and my calendar and all of my contacts seem to be fine, too. The button is still there where I used to be able to access my work email, but now when I try to open it, it goes directly to the “Set up account” process. All photos, videos and documents appear to be gone. But, when I connect the phone to my computer, it shows that the phone has about 8 GB of data on the internal memory and the external memory card has 812 MB of data. When I open the phone and card folders, both appear to be empty and say “0 items” in the status bar at the bottom. If I remove the external memory card and plug it into my computer, it shows five or six folders, including the DCIM folder where all of my photos are that have been save to that card. I have a Samsung Galaxy Note 3 running the 4.4.4 operating system. No modifications or customizations have been done, other than changing ringtones, etc. Honestly, I wouldn't even know how. Any idea what might be going on? Thanks very much for any input.
