Store review

Note 3 and S4 with Android 4.3 are not supported.

The app should be used with Samsung stock ROM device only. Rom like Cyanogenmod should not work at this moment.

Usually Samsung phone and tablet come with hidden menu or service mode. It is used to set and check RF status of mobile network. In mobile communication industry it is referred as engineering mode, field test display or net monitor.The hidden menu can be activated by entering secret code in phone keypad in most of the phone.

However, Samsung disabled the keypad support in some models such as Galaxy S III LTE and Galaxy Note II LTE. Besides, Galaxy Tab do not have phone support and hence it is impossible to activate the service mode directly. This app provides direct call to the service mode.
