I have a problem with 2 of my Roku stick devices. The remote control sometimes doesn't work unless I am standing next to the device (1 to 2 feet). I have try connecting the device to an HDMI extension so it is not hidden behind the TV but that didn't help. Also I noticed (not sure if it relevant to the issue) but batteries in botth remotes don't last to long (need to changes every month).
There mote on my phone roku app works perfectly.
Doe any one experienced this issue? Any idea how to solve it?
Honestly just sounds like the remote batteries are low. I don't know if your remotes support wireless listening (is there a headphone jack on the remote?), but if it does make sure you don't leave anything plugged into the remote when not using the headphones.
