Mobile read only mode does not work properly

[kausar007]

As part of #704 the change was implemented but it seems to switch back to edit mode on mobile devices.

Switching between pages and going tapping on Home brings back the virtual keyboard. Shouldnt it be in read only mode until we only tap on the edit button again?

Also looks like the button itself is not synced with state. Its gray at first, when you tap on it, it turns slightly blue showing its on. But if you tap on it again, it stays blue again.
