The remote for my Nexus Player is terrible. It's never worked consistently, but has recently give up altogether even with fresh batteries, attempted resyncs, etc. Is this a problem with the remote's bluetooth transmitter or the Player's bluetooth hardware? Is there anything I can do to fix it (I've got root access), or should I just look for a replacement remote? If so, any suggestions? I think I've read the Fire TV remote works well, but I don't know if that can be purchased individually.
Have you tried the remote app on your phone? Whether it works as a long-term solution for you is a matter of preference, but it's what I always use.
