Note 3 Lollipop Update problems and solutions

Since the update my phone has acted up BIG time. Camera goes into landscape mode and wont get out until I shut phone off and turn back on again. Lock screen letters and numbers go to blocks until I restart phone again as well. When I try to open apps the app store keeps opening to either Pandora or Zoosk on its own. The alarm clock doesn't turn off even when I tell it to I have to go back into the alarm to shut it off, and the ringer volume keeps going up on its own when set to silent. This is the WORST update yet for android phones!!!!
 
Yes, an unqualified thumbs up for all of the Cyanogenmod builds. I have never had an official CM crash or fail. I have found them to be robust, well thought out, and ahead of the tech curve. I have crashed every single one of my devices at some point, but that was just for funsies...

That said, however, be aware of the fact that the CM builds are the 80% solution for 80% of the users. I have found some builds for specific devices to outperform CM. Motorola's stock rom for the Droid Maxx Obake is a classic example - the stock 4.4.4 rom outperforms everything that I have tried (CM, Paranoid, Slim, AOKP - KitKat, Lollipop, you name it).

I am very interested in the anticipated CM13 builds, but more on that later.
 
Please help: I updated my Samsung Galaxy Note 3 to Lollipop. My issues are: Most of my downloaded apps are missing (including social media apps like FB, Twitter, and IG) and I cannot open my Google Play Store. Could someone please help? Thanks.

Here's what happened:
My phone informed me that there is a new update
I updated my phone with no errors whatsoever
My phone restarted. Everything is normal.
I decided to update all my applications through Google Play Store and some of my Galaxy Apps (Story Album, TTS, and Despicable Me)
Then I restarted my phone again.
This is when I realized that most of my apps are missing and I cannot open Google Play Store.

I will never buy another Samsung smartphone. My family's experience is that they have poor quality control, picky batteries, and they are a pain to work with.
