The abbreviation " VPN " has slowly become established among average Internet users, which is certainly good, but the problem is that people have started to see VPN as the ultimate solution to all problems.
Secret Codes are an integral part of all smartphones, and they are used mainly to test the functions of the phone. With them, you can find out what your phone is hiding or what it can do, what it has from the sensors, whether everything works from the hardware, etc.
These secret codes vary depending on the phone brand, model, and sometimes the network. In this article, you can find a list of over 140 secret codes for Android phones grouped by phone brands.
Keep in mind that some may not work, but also that you do everything at your own risk. I, and anyone else, am not responsible if any damage to the phone occurs due to the use of the information in this article. Before typing any code, you can check on Google if it still appears somewhere and thus confirms its accuracy.
It would be good to write down the codes you need for the phone you want to buy, especially if you are buying a used phone. I also wrote a special article on how to prepare for buying a used phone, so read on.
