Android App behaviour is different from Unity version

Hi all,

I builded and run my app on my Android mobile phone (Huawei P9 Lite), and I noticed that some things are different compared to the version I test through Unity.

The main problem is that a whole scene is not behaving as it should, the elements are in place, but nothing works right, as if the scene scripts were not loaded (there's a button that shouldn't be in the scene when first opened, another button does not respond properly and a slider does the same. To be specific, they notice the touch, but then nothing happens).

The other scenes work fine, as far as I can tell.

Does someone know what's the problem? In the building settings maybe? Or something in the scene?

Thanks in advance and have a nice day!
