[AC Question]

Since upgrading to Lollipop my Tab S has become very unstable mostly in staying connected to my router.

Another thing is my browser, both Firefox and Chrome. Neither will stay connected and slow to a crawl often totally locking up and forcing the rest of the apps to also crash.

As if the browser isn't enough both email and YouTube crash also.

I'm very frustrated. I don't believe going through a long list of possibilities is something a user should have to be put through. A operating system upgrade should make a device more stable not unusable.
