Problem: From one to three times a week the remote will not work. Nothing, no buttons will work. To correct this I must remove both batteries, then unplug the power from the Roku device, wait at least up to 60 seconds, after power is applied to Roku, re install batteries into the Roku Remote, push the button with the battery cover removed, watch the green light flash, hope for the best. The battery reads 100%, not every time, but 25% or more.
