The mobile version is still undergoing development and is planned to be more supported in future developments. So far the only mobile device to support the majority of things is the nexus 5.
Mobiles currently only support static lighting and no HDR or eye adaptation, so your scenes will appear really dark, you can get around this or work too this by placing a post processing volume, going down to eye adaptation at putting min brightness as high as you can get it; It should no longer adjust and should somewhat represent what you can see on your phone devices.
