There are few more mysterious concepts in Android phones than secret codes: phone numbers that don’t call anyone, but that special menus open.
These codes are mainly for the use of the technical service or to obtain useful point data, such as the IMEI of a mobile.
With some exceptions counted in which the manufacturers agree, Each brand has its own secret codes and often they change from one version to another and even from one model to another.
Here we will talk about the secret codes available on recent Huawei phones and everything you can do with them.
Project Menu is Huawei’s most prominent secret menu, hidden behind a fairly long and hard to remember code. Inside there are six sections that mix information with changes in some settings. The code you must write in the phone application is as follows:
* # * # 2846579 # * # *
Background Mode It is the first section you will find in that menu. Here are three subsections with configurations designed to diagnose and solve problems with the mobile. In Background Debug Y AP LOG Settings you can activate the internal registry to debug errors while in USB Port Settings You can choose the standard behavior of the USB port (HiSuite, default or factory).
Veneer Informations It’s something like the “chassis number” of the mobile. It is a kind of hypervitaminated version of the system information, breaking down the versions and subversions of virtually all the components of the mobile. It is subdivided into three categories: Version info, Manufacture Info Y Other Info.
Network Information Query It is the place you should go to get more information about your mobile networks. It is subdivided into PLMN Info (PLMN is a code that combines MCC and MNC), as well as SIM Lock Info, where you can know if your mobile is locked to work only with the SIMs of a specific operator.
Another interesting section, especially if you have bought your mobile phone abroad, is Vendor Country Info. There you are shown for which region this mobile was manufactured.
Keep in mind that the text may be somewhat abstract, as in the following screenshot: hw / spcseas it’s Asia, and hw / eu It is Europe.
Upgrade Software It is the next section, used to install system or application updates. It is a way designed so that the technical service can make repairs and updates of the system and applications in the mobile, when there are problems to carry them out by the traditional method.
Restore Factory It is the following menu. As the name implies, it will restore the factory mobile, although this requires you to first deactivate any protection in the mobile lock.
Keep in mind that these hidden menus do not have to have as many protections (that is, ask for confirmation) as traditional menus, so be especially careful with it.
The last menu is Battery Charge, intended to show you some additional information about the battery and its charge. A QR code is included with the battery serial number, the current charge level and the battery temperature. Above, the charging status is also indicated.
Unfortunately this battery information does not go as far as other brands and the number of charge cycles is not included. After all, they are menus designed for internal use of the technical service.
About of the phone
In this case it is not so much a secret menu, but rather a shortcut. If you need to know the IMEI, serial number, model or other details of your Huawei mobile quickly, one way to do it is with the following code. When you write it, the section opens directly About of the phone of the Android settings.
* # * # 0000 # * # *
This other code is tremendously specific, showing you information about the different calendars which are synchronized on the mobile. The information, of course, is limited to indicating how many events are registered in each calendar.
* # * # 225 # * # *
FCM stands for Firebase Cloud Messaging, a system to send messages and push notifications to the mobile so you can, for example, receive new messages in an app like WhatsApp or Telegram. This section shows you information about this type of notifications, as well as the last messages that have been received.
* # * # 426 # * # *
See the IMEI
It’s a classic, but we couldn’t forget probably the least 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 mobile serial number.
