About a week ago I went to turn on my wifi on my s3, but now when I turn it on it doesnt shut off my data. It leaves it on, so I have both a wifi icon and a 4g icon. When it does this the wifi never works right, and the data stays on. Im not sure what caused this. I havent done anything different to my phone. Is anyone aware of any known issues with wifi on JellyBean 4.1.2? Any help would be great! thanks!
