Original code for Sony Xperia. "Secret" - Xperia engineering codes

Articles and Lifehacks

Just a few years ago, devices with touch displays have become incredibly popular. However, many still do not know how to get into service menu, for example, in order to Sony Xperia Z or any other smartphone.

The beginning of the “boom” of touch screen devices occurred with the advent of the well-known Prada model from LG in 2007, and very soon this trend was picked up by other manufacturers. The model itself was interesting due to a number of characteristics and stylish design. For example, the video shooting speed was 30 frames per second, and for that year it was very decent. However main feature The device still had a touch screen, which could be controlled using your fingers rather than a stylus. Of course, even before 2007, unprecedented communicators based on Windows Phone, however, they still remained devices of a completely different class than Prada.

What is the Xperia Z service menu from Sony and how to get there

Unfortunately, not every owner mobile device knows what the service or engineering menu is and what it is needed for. Please note that you only need to enter it experienced users, otherwise you may cause irreparable damage to your device.

The service menu contains information about the smartphone and also allows you to configure certain parameters. In addition, it collects data about the use of the device (information about GPRS, battery, network, etc.). It should be used only if you have the appropriate skills and with extreme care, since any changes made will affect the operation of the device.

So, how to get to the service menu on Sony Xperia Z? To do this, just dial the combination *#*#7378423#*#*. Now you can start using the menu.

Other specs and features of Sony's Xperia Z beyond the service menu

The device was released in January 2013. It works for Android based JB and has dimensions of 139 x 71 x 7.9 millimeters. The smartphone weighs 146 grams. Its body is made of glass. The built-in 4-core processor has a Qualcomm MDM9215M chipset, which has already proven itself as a chipset High Quality. Although some believe that the devices on it have , but this is not entirely true.

The smartphone has a capacitive Full HD display with a resolution of 1920 by 1080 pixels and a diagonal of 5 inches. It is made using TFT technology. The screen is protected from moisture and dust. The glass itself is resistant to cracks and scratches. Xperia Z has 2 gigabytes random access memory and 16 gigabytes of built-in flash array. There is also support for micro-SD memory cards, which will increase its capacity up to 64 gigabytes.

The device has a built-in 13.1 megapixel main camera and front-camera 2.2 megapixel (with auto focus and flash function). There is support for 1080p video when shooting at 30 frames per second. The smartphone runs on lithium-ion powerful and non-removable battery capacity 2330 mAh.

Many users of Android smartphones and tablets are not even aware of the existence of so-called engineering or service codes. Service codes on smartphones and regular phones appeared much earlier than the first version of the Android OS was released. They are intended mainly for service center engineers and advanced users, so we immediately want to warn readers: if you don’t know what this code is for, then you shouldn’t enter it, and if you still decide to enter the code, then do it at your own peril and risk. It is worth thinking before entering any code for Android, because... this may lead to partial or complete loss of data and damage the device itself. If you decide to use codes, let's look at each engineering code in more detail:

*#06# - Find out IMEI;

*#*#4636#*#* - Information and settings;

*#*#8351#*#* - Voice Dialer Logging Enabled;

*#*#4636#*#* - This code can be used to receive interesting information about the phone and battery. It shows the following 4 menus on the screen:
— Phone information;
— Information about batteries;
— Battery statistics;
— Usage statistics.

*#*#7780#*#* - This code resets following settings to factory:
— your Google account settings stored on your smartphone;
— data and settings of the system and applications;
- downloaded applications.
The code does NOT remove:
- current system applications and applications supplied with the smartphone;
— data on the SD card (photos, videos, etc.).
PS: Before resetting the settings, the smartphone will ask for confirmation, so until the very last moment you will have a chance to change your mind.

*2767*3855# - Think before entering this code. This code is used for factory formatting, that is, it triggers the deletion of all files and settings including those stored in internal memory. It also reinstalls the smartphone’s firmware.
PS: After entering the code, there is only one way back - quickly remove the battery and start data recovery via PC.

*#*#34971539#*#* - This code is used to obtain information about the phone's camera. It shows the following four parameters:
— Updating the camera firmware into the image (do not try to repeat this option);
— Updating the camera firmware on the SD card;
— Get the camera firmware version;
— See how many times the firmware has been updated.
WARNING: Never use the first option, otherwise your phone camera will stop working and you will have to carry your phone in service center to reinstall the camera firmware.

*#*#7594#*#* - This code can be used to change the mode of the End/On/Off button. By default, when you long press the button, a screen will be shown asking you to select any option: “Switch to silent mode", "Airplane mode" or "Turn off smartphone".
You can change the suggested options using this code. For example, you can make the phone turn off immediately, without selecting the desired option from the menu.

*#*#273283*255*663 282*#*#* - The code opens a file copying screen where you can make backups your data (photos, audio, etc.)

*#*#197328640#*#* - This code can be used to enter maintenance mode. You can run various tests and change settings in service mode for WLAN, GPS and Bluetooth;

*#*#232339#*#* or *#*#526#*#* or *#*#528#*#* - WLAN (use the Menu button to run various tests);
*#*#232338#*#* - shows MAC address WiFi;
*#*#1472365#*#* - GPS test;
*#*#1575#*#* - Another GPS test;
*#*#232331#*#* - Bluetooth test;
*#*#232337#*# - Shows the Bluetooth device address;

Codes for running various factory tests:
*#*#0283#*#* - Batch Loopback;
*#*#0*#*#* - LCD test;
*#*#0673#*#* or *#*#0289#*#* - Melody test;
*#*#0842#*#* - Device test (vibration test and backlight test);
*#*#2663#*#* - Touch screen, version;
*#*#2664#*#* - Touch screen, test;
*#*#0588#*#* - Motion sensor;
*#*#3264#*#* - RAM version.

These are the basic codes for Android that an advanced smartphone user may need. Let us repeat once again: do not enter codes if you are not sure of their purpose! But to solve some problems in the operation of the Android device, these codes are extremely useful.

Probably many smartphone owners have encountered volume problems. For example, I was not happy with two things. The first is the quiet sound of the speaker when there is an incoming call, and the second is very loud noise in headphones when there is an incoming call.

A little about how Android controls volume

If no headset is connected to your gadget (headphones, hands-free, etc.), then the volume settings will be the same, but as soon as you connect the headset, the settings will be different. For common understanding I'll tell you a few examples.

Example 1. You are listening to music on your phone, turned it on loud speaker at full power, and when you connect a headset to it and turn on the loud speaker again, the volume may differ (it can be louder or lower, depending on what model of phone or firmware version).

Example 2. You are watching a movie with headphones, the volume (meaning the multimedia volume) is set to 40% and then after a while you have an incoming call, then the volume in the headphones will change to the general volume, in which case you can get a powerful sound shock to your ears. Believe me, I jumped off the couch more than once in such cases, the fact is that the programmers did not set up the volume modes well.

Example 3. You're on a call and need to switch to speakerphone mode, and you notice that the speaker isn't as loud (or vice versa) as when listening to music; or your partner has begun to hear you poorly, this is because different modes The microphone may have different sensitivity. Also, when you connect a headset in the same situation and turn on the speakerphone mode, the settings are different again. This is how Android controls volume.

Let's learn the theory of the engineering menu

So let's look at what and how you can do if you tinker a little with the “Engineering Menu”.

Before making any changes, we recommend that you read the entire article, understand it, and then experiment. Also, take a piece of paper and write down all the default values ​​in case something goes wrong. You can launch the engineering menu using telephone dialing numbers: we write the following combinations on it (Fig. 1):

picture 1

*#*#54298#*#* or *#*#3646633#*#* or *#*#83781#*#* – smartphones based on MTK processor

*#*#8255#*#* or *#*#4636#*#* – Samsung smartphones

*#*#3424#*#* or *#*#4636#*#* or *#*#8255#*#* – HTC smartphones

*#*#7378423#*#* – Sony smartphones

*#*#3646633#*#* – Fly smartphones, Alcatel, Philips

*#*#2846579#*#* – Huawei smartphones

Congratulations, you have entered the engineering menu (Fig. 2). Please note that the menu is different phones may differ slightly in structure. Find the “Audio” section and go into it. After logging in, we see a bunch of unknown lines (modes) (Fig. 3). Here's what these modes mean in Android:

Figure 2 Figure 3

— Normal Mode(Settings section in normal or normal mode) – this mode is active when nothing is connected to the smartphone;

— Headset Mode(headset mode) – this mode is activated after connecting headphones or external speakers;

— Loud Speaker Mode(speaker mode) – it is activated when nothing is connected to the smart device and you turn on speakerphone while talking on the phone;

— Headset_LoudSpeaker Mode(speaker mode with a headset connected) – this mode is activated when you connect headphones or external speakers to the smart phone, and you turn on the speakerphone while talking on the phone;

— Speech Enhancement(phone conversation mode) – this mode is activated in the normal mode of telephone conversations, and nothing is connected to it (headset, external speakers) and the speakerphone is not turned on.

It’s best not to poke your nose into the last three sections:

— Debug Info– it’s not clear why – info on backing up information or debugging it;

— Speech Logger– I haven’t fully figured it out, most likely it was logging during negotiations or recording chatter. If you check the box next to “Enable speech log”, then after completion phone call V root directory memory cards, corresponding files are created. Their name and structure are next view: Wed_Jun_2014__07_02_23.vm (Wednesday_July_2014__time07_02_23.vm).

What these files serve and how they can be useful to us is unclear. The /sdcard/VOIP_DebugInfo directory (which is the storage location for files with backup information) is not created automatically; if you create it manually, it will remain empty after the conversation.

— Audio logger– good software for recording sound that supports quick search, playback and saving it.

If you approach these modes wisely, you can adjust the volume of Android smartphones or tablets the way you want. When you enter any of the modes, your view will become available various settings volume (Type). Here is a list of the basic settings you need to know (Fig. 4):

figure 4

—Sip– settings for Internet calls;

— Mic– microphone sensitivity settings;

— Sph- settings conversational dynamics(the one we apply to the ears);

— Sph2– settings for the second speaker (I don’t have one);

— Sid– skip, if you change these parameters during conversations on your smartphone or tablet, you can hear yourself instead of your interlocutor;

— Media– adjusting the multimedia volume level;

— Ring– volume level adjustment incoming call;

— FMR– FM radio volume settings.

Next, under the settings selection item, we have access to a list of volume levels (Level) (Fig. 5). For a better understanding, there are 7 such levels, from level 0 to level 6. Each level corresponds to one “click” on the volume rocker of a smartphone or tablet. Accordingly, level 0 is the quietest level, and level 6 is the loudest signal level. Each level can be assigned its own values, which are located in the Value is 0~255 cell, and should not go beyond the range from 0 to 255 (the lower the value, the lower the sound). To do this, you need to erase the old value in the cell, then enter a new one (desired) and press the “Set” button (the one next to the cell) to assign (Fig. 6). When using the maximum values, be careful as the speakers may produce uncharacteristic unpleasant sounds in the form of rattling and other unpleasant effects.

Figure 5 Figure 6

Warning! Before making changes, rewrite all factory values ​​(in case something goes wrong).

You should know this!

Editing modes in the engineering menu

Example 1. How to increase the volume of an incoming call?

To do this, you need to go to the engineering menu, select the “Audio” section, go to the “LoudSpeaker Mode” and in the volume settings select “Ring” - the volume settings for the incoming call. Then sequentially change (increase) the values ​​of all signal levels (level 0 – level 6). Also for greater effect you can increase the value of the Max Vol section. 0~160, if it is not maximum (I set it to 155, with higher value the speaker starts to wheeze).

Example 2. How to increase the volume when talking on the phone? (Increasing the volume level of the small speaker, the one we put to the ear).

Again we go to the engineering menu we already know, press the “Audio” section, go to special mode“Normal Mode”, in it we select Sph - this parameter is responsible for changing the value of all signal levels in the range from level 0 to level 6. We set the level we need. In the Max Vol. 0~160, also can be changed to more high value volume power.

Example 3. Increasing the volume and sensitivity of the smartphone's conversational microphone

To adjust and set the required volume level and sensitivity of the spoken microphone, you need to go to “Engineering Menu”> “Audio”> “Normal Mode”> select Mic - microphone sensitivity settings, and for all levels (level 0 - level 6) assign one and the same value, for example 240. Now the interlocutor should hear you better.

Example 4. How can I increase the audio recording volume during video recording?

Let’s assume that there is a need to increase the volume level of sound recording when shooting video, then in engineering menu for our loudspeaker (LoudSpeaker Mode), change the microphone sensitivity settings (mic), increase all values ​​at all levels (level 0 – level 6), for example, set 240 at each level. I remind you to press the (set) button - reboot your favorite gadget and rejoice.

By the way, do not forget after each edit a certain parameter press the “Set” button. This action should capture and accept your command. Otherwise, user installed the parameters are not activated. In addition, a certain amount mobile devices require a reboot for the changes to take effect (turn off and on the device).

Good luck in your experiments, if something is not clear, write in the comments. We are waiting for your answers.
