There are fewer misconceptions on Android phones than secret codes: phone numbers that don't call anyone, but that special menus are open. These codes are not intended for use in a technical service or for accessing useful point data, such as mobile IMEI.
Unless otherwise stated by the manufacturers, Each edition has its own secret codes and they often switch from one version to another and change from model to another. Here we will talk about the secret codes found on the latest Huawei phones and all you can do about them.
Project Menu
Project Menu is Huawei's famous secret menu, hidden behind a long code and hard to remember. Inside there are six sections that mix information and changes to other settings. The code you should write in the phone app is as follows:
* # * # 2846579 # * # *
Rear Mode It's the first category you'll find in that menu. Here are three components with optimizations designed to diagnose and troubleshoot mobile. In Adjusting the layer
Details of the Vener Something like a "chassis number" for a cell phone. In the form of a hypervitaminated version of the system information, it breaks versions and translations of almost all parts of the cell. It is divided into three sections: Version details, Production Information and Other Information.
Network Question It's the place to go for more information about your mobile networks. It's split in half PLMN details (PLMN is a code that combines MCC and MNC), as well as SIM Lock Info, where you don't know if your phone is locked to work only with specific SIM cards.
Another exciting part, especially if you've bought your mobile phone overseas, Merchant Country Details. There you are shown which phone this region is made for. Keep in mind that the text may appear somehow, as in the following screenshot: hw / spcseas
Upgrade Software It is the next step, which is used to install app or app updates. It is a system designed for the technical service to perform maintenance and update of the system and use on mobile, where there are problems with doing it the traditional way.
Restore Factory Next menu. As the name implies, it will restore the cell phone to the factory, even though this requires you to first activate any mobile key protection. Keep in mind that these hidden menus do not need as much protection (ie, ask for confirmation) as traditional menus, so be very careful about them.
The final menu is Charge the Battery
Unfortunately this battery information does not go as far as other products and the number of charging cycles is not included. After all, menus are designed for the internal use of a technical service.
About the phone
In this case it's not such a secret menu, but rather a shortcut. If you need to know the IMEI, serial number, model or other details of your Huawei mobile phone immediately, one way to do it is by the following code. When you write it, the paragraph begins exactly About the phone in Android settings.
* # * # 0000 # * # *
Calendar details
This other code is incredibly clear information on different calendars which are synced to mobile. The details, however, are limited to show how many events are registered in each calendar.

Diagnosis of FCM
FCM stands for Firebase Cloud Messaging, a system for sending text messages and forwarding notifications to mobile phones, for example, to receive new messages from an application such as WhatsApp or Telegram. This section shows information about this type of notification, and the last messages received.
* # * # 426 # * # *
See IMEI
It's a classic, but we couldn't forget perhaps the smallest secret code: code to see the mobile IMEI. On Huawei phones, it is displayed along with other information including MEID, PESN, IMEI for each SIM and portable serial number.
