Did a Hollow Zero run on my phone. It's a midrange poco x6, capable of running GI and HSR at medium to high settings. I had frame drops even at the lowest graphics settings and 30fps. The experience was still playable, I guess.

The game's really not meant for phones, huh? Like, some elements in the UI such as fairy's messages in the far right corner of the screen are too small to read on a phone.
