I only have Rev_A and Firmware 1.12. The mydink home version is 2.1.0 build 31. Android version is 4.4.2 and I don't see the issue. When I tap on the meter, the screen appears and stays there.
Probably best to contact technical support in your country to have them look into the issue further.
Also try uninstalling and re-installing the app and see if that helps.
