Well, to prevent that from happening you can check with Secret code because the general public is also able to do so provided they understand the various codes used.
If you want to do it, you are recommended just to look around without changing the settings at all. Because, setting errors or settings in the secret menu can have a fatal impact. Your gadget may be no longer working and eventually have to go to a repairman.
For the first in order to enter the secret menu we have to access it by entering the code *#*#4636#*#* in mode dial mobile number.
Generally, in this menu, there are 4 sub-menus, including Phone Information, Battery Information, Usage Statistic, serta Wi-Fi Information.
For Phone Informationthere is information such as number International Mobile Station Equipment Identity (IMEI)network connection currently being functioned, network preference settings, etc.
In Battery Information, includes information about the condition of the battery, voltage, and temperature. Wi-Fi Information can be used to Ping & disable or enable certain networks.
Whereas Usage Information contains info about the last device or application used by the mobile phone & an explanation of how long the cellphone has been used.
Actually, the code *#*#4636#*#* can be used for every category of Android Smartphones. However, when you try it, you may find that this code does not work on certain smartphones or that it does not show the entire menu.
Important Things to Observe
