According to [http:// MCPE-12422 https://bugs.mojang.com/browse/MCPE-12422], there seems to be an issue with vertical height based monster spawner in MCPE. This is the most basic mob spawner, and mostly portrayed in youtube-videoes. In essence, they don't work as in MC.

In addition there is a limit with how many mobs spawn close to the Player, which affects some of the other designs. But the tubular design (see comments on linked bug) should work to some extent, although I haven't built one myself.

In my experience, your best bet (with exception of cheating and using Creative mode) is to find the Monster Spawner naturally, and build a grinder around this. I've succesfully built quite a few, and had success with them. The best one is based upon a Skeleton Monster Spawner, which gives me loads of arrows and experience (and armor in a previous MCPE version).

I can't predict the future, but my guess is that you won't be able to break and move them, so you'll have to stick to finding them.
