In the latest version, 1.21.100.6, there is a bug, or perhaps more precisely, a glitch, in the texture of the leaf block, torch, Fire and several other items. I've tried various things, such as re-downloading the application and deleting the application data. My phone's specifications are low, only 3/32 Helio P22, and that could be the reason why my report was ostracized.
