Mobile lag spike first play of game

I’m developing a game for GearVR and am running into a weird issue: the first time I run the game, every new asset that loads in causes a major lag spike. The weird part is that this only happens the first time I play the game after install. Once I’ve played the game loaded all possible assets once, all subsequent plays have no lag spikes. Any ideas?

Hi,
Have you ever found a solution to this ? It also happens to me on Android development
