When I wrote that article, all the secret codes mentioned in the article worked on almost all Android mobile phones, but with the release of new versions of the Android operating system like KitKat, Lollipop, etc., many of the codes stopped working on many Android smartphones. Also, many mobile device manufacturing companies, such as Samsung, disabled those codes, so most of the codes no longer work on those mobile device brands, especially Samsung Galaxy series phones. 

But today in this topic, I am going to share many new hidden secret codes that will work on all Samsung smartphones, be it Samsung Galaxy S series, A series, J series, On series, series mobile phone. Note or any other Samsung mobile model. 

I found these codes by decoding and reading various system files of the Samsung Galaxy S6 firmware. These secret codes can be used to access many hidden service menus (engineering mode) and useful options on your mobile phone to test hardware and sensors, update firmware, and find out many cool things that are generally not available in settings. of the telephone.
