Ok, as mentioned in the subjecT I have the Samsung galaxy s4 through U.S. cellular. Idk what's wrong with my phone the last couple months it's been going super slow even in the Wi-Fi! But what's really irritating me is when I go to the default internet and I go to close out the Windows and a message pops up, "Unfortunately, Internet has stopped." Every time, no matter how I come about it. I have tried restarting the phone, master reset, took the sd card out, went through the apps and killed it! I swear other things too I just can't remember now lol. And after I click ok, it reloads the internet back on the last page I was on. Even if I clear the browser history, the windows are still there!!! Please, someone help me!!!
