Do all Android ARCore devices support ASTC?

[synthercat]

I noticed that on the Unreal page (https://developers.google.com/ar/develop/unreal/quickstart) there is a part telling us to export using ASTC... why isn't there such an instruction for Unity?!? Should I use general texture compression ASTC or stick to ETC2?

Also since I am asking that... Do all Android ARCore devices play HEVC h.265?

I know this isn't a designated place for such questions but I couldn't think of a more proper place full of Unity/ARCore users. Thank you for understanding.
