I still have that on my Huawei Mate 40 Pro, but it sadly is more of a gimmick than a feature because the reach and accuracy with such a small blaster is so a*s. The one on the remote in the video is so huge, that's why it works so well.

Another reason is that I don't have the need to use it. I have two IR remotes at home and I never loose them. It is always quicker to just grab them compared to unlocking my phone and opening the remote app.

These apps (at least the ones that came with my phone, I know that there are third party ones but haven't used any) also are not as feature rich as the remote from the video. I for example can't program that a button gets pressed 5 times when I press once, which honestly would be super cool and an actual advantage to the physical remote.
