MCPE-8140Monster are not willing to attack people who are in double-tall plants
When I was AFK in a double-tall plant, I saw that there was a creeper thats 5 blocks away from me and its not gonna attack me. But once I walk away from the double-tall plant, the creeper starts chasing me. This glitch not only works in iOS, also android and PC version!

It's because you're pretty much hiding from the creeper. The creeper's AI counts the double-tall grass as 2 actual blocks, thus making it unable for the creeper to actually see you. This actually comes in handy for me as I enjoy using it as a battle tactic against mobs.
Basically what Bryan said. Not a bug, an intended feature
Alex, this is an issue with the current mob pathfinding. Most likely unintended.
Okay Pat
Confirmed on Samsung Galaxy S4 Android 4.4.2 running MCPE 0.10.5. As discussed this may be a bug or an intended feature, but I'll leave that for the developers to tell us.
This happens to on PC. Not sure if it is a bug or not.
Is working as intended, because this is a feature in the AI than a bug.
Luis, I tend to doubt this as (currently) intended behavior, and would prefer to allow a developer to comment before resolving this as WAI.
This is not WAI. This is a bug and it should be fixed eventually
