Hi! Got a Philips 7354 The One Android TV last december and have so far been thoroughly enjoying it. Features are great and ambilight is a nice surprise.

However, I can't help but notice the RakutenTv and Philips TV buttons that I'm not gonna use, probably ever. Was wondering if I could remap them to things like YouTube, which would be way more useful.

Also, I'm having trouble casting to the TV, from an android phone mind you. I can cast to another Chromecast no problem but casting to this TV proves quite... erratic. I've done it already but the cast icon appears once in a blue moon.

Any ideas? Thanks in advance!
