Until today, everything was working fine. But now my computer is not recognizing my S4. When I plug in the cord it charges the phone, but I can't access it. Any thoughts?
Do you see the notification when you plug in? If not check Settings--> Storage-->navigation right button -->USB computer connection > Media device (MTP)/ Camera PTP
You've got me on a couple of things. Which notification are you referring to? I see that the phone is charging. And I'm not sure what the right navigation button is.
