Last week I received my new Ultra 4670X to replace a older model. The remote will completely stop working after several minutes. Pull a battery and reinsert and it will work again for a few more minutes. New batteries. Batt. Indicator also shows full. Re-pairing has no effect. Warranty replacement?
Roku Ultra 4670X, Serial # YJ009H061784
I would return to Amazon but have disposed of box.
Please send me a PM with your Roku account email address, and include the serial number of the Roku device from Settings>System>About along with a summary of the issue you are experiencing. I'll be able to assist you further from there.
