Well that should NOT be the experience of new owners. 🙂 The remote should work very consistently and reliably.
You said that your other remote exhibited the same issues. To be clear, does this mean that the Game Frame would see a unique code followed by the 0xFFFFFFFF repeat code until you released it — but occasionally it would also get totally random codes interspersed between the repeat codes? As you suspected, I think we’re zeroing in on something wrong on the receiver end.
