I own a Philips 55PUS7303 running Android TV. I found the option to rename the device and changed it to "Living Room TV" so that I can refer to it more easily with Google Home. This works fine for a little while, but then without warning seems to revert to the factory default setting of 55PUS7303/12 (I've no idea how the 12 gets in there!)

Has anybody else had this problem, with this or any other Android TV? Is there something I'm doing wrong, or something I can do to prevent it? Is this worth returning the TV over? (I'm well within the warranty returns window).

It's frustrating, because otherwise I'm absolutely in love with this set :/
