Photon synchronization on different devices failes

I've recently set up the Photon multiplayer for my game and it works fine on localhost on my computer. Each player can give an input and set an action to the scene game objects. I tried to test the multiplayer on android and desktop, but apparently the synchronization fails almost totally. Not only the objects move haotically or not at all, but at some point the second client's input, more specifically the client that joined the room and did not creat it, cannot be seen on the other client. I've used RPC calls which work just fine on desktop as aforementioned, but they dont seem to make a difference.

The description of the game is this: I have a button and a scene game object. Whenever a client presses the button the scene game object suffers a transformation. The concept is easy like that. I've put Photon View on my scene objects, created RPC calls functions for modifying the state of the object, basically I've done everything I was advised by other users.

I would like to be given suggestions concerning this problem. What should I do? Does it have anything to do with the network state of the devices? Should you take a look at my questions from a few days ago, you will find some relevant script for connecting to a specific room.
