I need to check a "ground plane" to put objects over it without a marker, using Unity.
Right now I'm using Vuforia, but the Ground Plane on Vuforia only works on some devices, I tested on mine and my mother's Android phone, both modern and from different brands, didn't work. So it's not an option, because many many people couldn't use it.
Same with ARCore, asked me to install some sort of Google Services AR, which the download is locked for my phone.
Is there any way to use Unity with some kind of ground plane detector that many phones can "read" it? Any API, code, anything different that I didn't try yet?
