Hello from the Philippines!

I'm new to the forums.

I hope you can help me understand why both my Moga Pro controller and Sony Smartwatch won't connect with my Acer devices running Jelly Bean:
Acer Z2 Phone:
Acer B1 Tablet:

I tried both accessories with the phone and tablet - neither works. I followed the instructions and downloaded the required apps but I still can't get either to work.

However, when I tried them on an old generic Gingerbread phone from China, both accessories worked perfectly!

I thought maybe one of the apps I installed might be causing the problems so some setting I set, so I reset both devices, downloaded the required apps again, and tried to pair.
Still nothing.

I just don't get. Can anybody help?
Thanks in advance!
