Using channel up/down in guide to page up/down goes in reverse

[saturnaqua 5]

Not sure what's up here, but I'm using an Onn 4k box. As I got a new Onn 4k plus and I've heard that the android tv version will eventually be supplanted by the android app version, I installed the android (non-tv) version and it's 3.5.28. I notice on the remote, when I'm in the guide, if I use the channel up/down buttons (not the circular D-pad), then the guide moves in the opposite direction. Clicking the channel up makes the guide go down and channel down goes up in the guide. Having used the android tv version, I thought this was weird since there, channel up moves the guide up one page and channel down goes down one page.

HI, I guess it depends on your thought process about this, and whether channel up/down means up/down visually or in terms of up/down channel numbers.

My channel lineup is configured for channel number low to high. So at the very top of my guide is over the air channel 2.1 and the bottom of the list is channel 67.1

The onn remote has some buttons that act differently depending on context. It looks like the following:

You'll see there is a volume +/- which obviously only works on the physical TV as well as the mute. To the right is an ^ and v which if used in TV context, is channel up/down. However, in the Onn box apps, it seems like most apps expect the D-pad to do the channel up/down in guides (as tested in free apps like Pluto/Roku channel/Tubi/Xumo). The channel up/down doesn't do anything. When I use Emby, the ^ and v act as page up/down in the guide as expected (android tv version). When I use the universal android app, pressing ^ makes the guide go in the opposite direction. This means, if I am on say, channel 45.1, pressing ^ moves me down to like channel 54.4 down the list, when the android tv Emby goes up the list to channel 21.1 in the EPG. Here are some pics:

Android TV starting at channel 45.1

Press v (page down):

go back to 45.1 and press ^ (page up):

Now on the universal Emby for Android app, again starting at 45.1:

Press v (page down) I end up on channel 21.1 which is further up:

Return to 45.1 and then press ^ (page up):

The android tv version acts like expect a page up/down same as like the old windows media center or tivo style guides, while the universal app acts the opposite way I would expect. I'm not sure how much the universal app was tested against tv boxes and remotes, but I suspect it's just in the code the mapped buttons are reversed for the function calls. I don't think this is specific to Onn boxes either as someone I know has a FireTV box and I believe the newest remote has a channel or page up/down button and they verified the same behavior as I'm seeing.
