Hello,  

as title say i try to use the *#0228# but nothing happens. Other codes works fine.

Am i missing something? 

Thanks you very much.

@Anonymous User The code is possibly in connection to the battery. CCalibrationand or " Another useful hidden menu is for checking the battery voltage. Enter *#0228# in to the phone dialer and you'll see the change in voltage when you charge it "

@MaurizioAnnoni it's possible the codes won't work on every phone due to the region the phone was released in or due to current software permissions.

A phone supplied directly from a network fkr example has it's own flavour of software on it and different csc so may react differently.

If I can be of any further help then please don't hesitate. Take care.  😎
