When i was underground close to bedrock i was smashing the red stone blocks with my iron pickaxe and diamond pickaxe and when it was close to demolish the block nothing came out of the red stone blocks like it should and I used all types of pickaxes and red stone blocks are noncollectable and i was told by a friend who also plays on Minecraft Xbox version that it is collectable but on my Samsung Note 2 when im playing on my cell its not. Is there a bug or something that is not allowing to collect or something?
