Android,Mali T860; GPU is supposedly "compatible" with Vulkan but

[GamerRukario]

I have researched that the Mali T860 should be compatible with Vulkan but I can't enable the options in the game, it just returns the option to Opengl. Is it because of the emulator? Do I have to update the phone? Somehow add the API to the phone? I tried researching how but everything I saw is about creating apps or some similar stuff.

The phone is an LG Stylus 3 M400DK. Octa-core 1.5 GHz Cortex-A53 and Mali-T860MP2.
