Problem with vibration...

Hey, guys, I'm having a problem with the vibration.

I put the vibration with Browser and a "200,100,200" pattern, when I exported I put the tick on "Request vibration permission", but it doesn't work.

If I try it with the editor (remote preview) on my phone it works. If I try to export it as apk android and load it on my phone it doesn't work.

I also tried it with other devices but nothing.

Where am I wrong? D:

thanks a lot!

none? D;
