Question: I really enjoy minecraft. So I downloaded the pocket edition. But when I go into my inventory, there is no craft button. Is there a way to fix this?

Answer: 
They have recently changed the inventory screen on Minecraft PE, the new screen looks like this, and runs using various tabs shown on the left.

You just need to click the bookshelf and it will open the crafting menu.

For reference the old screen looked like this.

The 3 dote beside the hot bar (quick select). Then push the bookshelf button.
