I have an S4, and I'm running 4.2.2 right now. Previously when I updated to 4.3 I had TONS of issues, and I now I am back at 4.2.2, but it's constantly popping up telling me I have 15 minutes to close all my apps for a "Samsung Update", which is essentially 4.3 which will mess up everything. How do I turn the auto updates off and just stay at 4.2.2 until they figure out a patch that won't break everything?
