Same thing with me i cant seem to turn it on. In 3rd person when i look at the torch from the front it does look like its on, but it doesnt acttualy hit objects or the enviroment

Are you sure you have a full battery attached to it?

It happens with me too. When there's the light of day it doesn't turn on never, what I thing it's a bug. At night, sometimes you have to remove the battery and attach again to work and also there is times that even doing this it doesn't turn on, so we have to keep trying until the bug fixes by itself.

it was the battery from the start and the first use.
today i tried it one more and it works now ... something was broken yesterday
