There are few more mysterious concepts in Android phones than passcodes: phone numbers that don’t call anyone, but rather they open special menus. These codes are mainly intended for the use of the technical service or for obtaining specific useful data, such as the IMEI of a mobile phone.
With a few rare exceptions on which manufacturers agree, each brand has its own secret codes and they change frequently from one version to another and even from one model to another. Here we will talk about the secret codes available in recent Huawei phones and what you can do with them.
Project Menu is Huawei’s most important secret menu, hidden behind a rather long and hard-to-remember code. Inside there are six sections that mix up information with changes in certain settings. The code you need to write in the phone application is as follows:
* # * # 2846579 # * # *
Background mode This is the first section you will find in this menu. Here are three subsections with settings for diagnosing and fixing issues with the mobile. At Debugging in the background Yes AP LOG settings you can enable internal logging to debug errors, while in USB Port Settings you can choose the standard behavior of the USB port (HiSuite, default or factory).
Plating Information It is something like the “chassis number” of the mobile. It’s sort of a hypervitaminated version of system information, breaking down versions and subversions of virtually every component of the mobile. It is subdivided into three categories: Version Info, Manufacturing information Yes Other info.
Network Information Query is the place to go for more information about your mobile networks. It is subdivided into PLMN Information (PLMN is a code that combines MCC and MNC), as well as SIM Lock Info, where you can find out if your mobile is locked to work only with SIM cards from a specific operator.
Another interesting section, especially if you bought the mobile phone abroad, is Supplier country information. You are indicated there for which region this mobile was manufactured. Note that the text can be somewhat abstract, as in the following screenshot: hw / spcseas th is is Asia, and hw / me
Software update is the next section, used to install system or application updates. It is a mode designed so that the technical service can perform repairs and updates of the system and applications on the mobile, when there are problems to achieve them by the traditional method.
Restore the factory is the next menu. As the name suggests, it will restore the factory mobile phone, although for this it first requires you to turn off any kind of protection in the mobile lock. Keep in mind that these hidden menus don’t necessarily have to have as many protections (i.e. asking you for confirmation) as traditional menus, so be especially careful with this.
The last menu is Battery charge, intended to show you additional information about the battery and its charge. A QR code is included with the battery serial number, current charge level and battery temperature. The state of charge is also shown above.
Unfortunately, this battery information does not go as far as that of other brands and the number of charge cycles is not included. They are, after all, menus intended for internal use by the technical service.
About the phone
In this case, it’s not so much a secret menu, but rather a shortcut. If you need to quickly know the IMEI, serial number, model or other details of your Huawei mobile, one way to do it is to use the following code. When writing, the section opens directly About the phone from Android settings.
* # * # 0000 # * # *
This other code is extremely specific, showing you information on the different calendars which are synchronized on the mobile. The information, of course, is limited to indicating how many events are recorded in each calendar.
* # * # 225 # * # *
FCM stands for Firebase Cloud Messaging, a system for sending messages and push notifications to mobile so that you can, for example, receive new messages in an application like WhatsApp or Telegram. This section shows you information about these types of notifications, as well as the last messages received.
* # * # 426 # * # *
It’s a classic, but we probably can’t forget the less secret secret code: the code to see the mobile IMEI. On Huawei phones, it is displayed along with other data including MEID, PESN, IMEI of each SIM and the serial number of the mobile.
