Happening for me too
Also my radio remote navigation buttons sometimes do more than what they are supposed to.
for instance, down = down-right about 1/7 of the time
left = left+up about 1/7 of the time

remote batts at 100%
tried with various screensavers.
tried with and without menu sounds
tried with graphene and roku theme
behavior never changed.
The blinking light blinks at about the rate of KITT's wow-wow sound in Knight Rider.
I can live with the blinking light, but the wonky remote navigation problem is starting to annoy.
The navigation buttons misbehaving is clearly a software issue, I disassembled (https://www.reddit.com/r/Roku/comments/2rl5dy/roku_3_remote_control_volume_button_not_working/
) the remote to ensure that it hadn't somehow attracted some ketchup on the contacts. It is clean.
I would consider upgrading to stick, but, I refuse to reward a company buy buying their new product after their actions mess up their current product. (insert diatribe about VW's TDI diesel here).
