...buy an inexpensive universal remote. Done.
I have a 3 week old Samsung J5600, and this evening the remote started playing around, turning sport mode on and off constantly. Now, after replacing the batteries, it won't work at all. Anyone else suffering from this issue? And what's the best way to resolve it?
