wrong rendering skybox on android

Hi! when I build the project on Android (Galaxy S6 Anroid-> ASTC & Android-> ETC2) and choose the size (scale) skybox (10000x10000x10000)textures appear in the defect, but the size (scale) skybox 1x1x1 - everything is fine. what should I do?
the problem only appears on your phone, on PC with skybox (10000x10000x10000)everything is fine!
