Sony xperia hotkeys. Service codes for Sony Xperia Z1 Compact

Articles and Lifehacks

Over the past years, on various thematic forums and in comments to reviews of mobile technology, you can read many reviews that, although smartphones are becoming more and more technologically advanced, they cannot be used for their intended purpose in the literal sense of the word. Sometimes you even have to, because it doesn’t suit the subscriber. Many are also interested in what they represent service codes for Sony Xperia Z1 Compact.

Note that this mobile equipment manufacturer obviously listens to the needs of its customers. This is evidenced by the release of such a device.

Description of the Sony Xperia Z1 Compact smartphone. Why are service codes needed?

The mini version of the flagship Xperia Z1, Xperia Z1 Compact, despite its small size, is quite a powerful, functional and advanced device. Its compactness appealed to all those who do not support the constant trend towards increasing the size and diagonal of the display.

The Xperia Z1 Compact smartphone cannot be called an alternative to any other devices from Sony. The same goes for its competitiveness. For example, the predecessor of this product, Xperia Z1, became a competitor to such a device as the iPhone 5S. Sony was faced with the difficult task of producing a device that would interest potential buyers, and it seems to have done a great job.

Why do you need a service code? With its help, an ordinary user can access all those functions that are not available to him in the usual way. For example, he can enter, otherwise called service. However, you should be aware that working in such a menu is recommended only for a trained user, since any change made will have a certain effect on the operation of the device.

Some service codes for Xperia Z1 Compact from Sony

So, here are a few codes that may be useful to the owner of this device. For example, to enter the above-mentioned engineering menu, you should enter the combination *#*#SERVICE#*#*. A code like *#*#7378423#*#* will also work. It happens that the codes from different manufacturers are the same, but in most cases they are individual.

What other service codes exist for Sony Xperia Z1 Compact? For example, to find out information about the battery and the smartphone itself, you need to enter the combination *#*#INFO#*#*, or *#*#4636#*#*.

A few words about the device's battery. Considering the dimensions of the mobile device, it was not initially possible to install a battery with the same power as the Xperia Z1. The battery capacity of the device is 2300 mAh. Despite this, the battery life of the device is quite decent. The user will be able to talk non-stop for 20 hours, and also set the device to standby mode for almost 30 days. Of course, Sony specialists worked hard when developing the Xperia Z1 Compact.

To enter demo mode, dial the code *#*#73556673#*#*. You can exit it in the same way. This mode is needed so that the user can become better acquainted with his device. If it is activated, the display is locked and an advertising video begins to play on it, demonstrating the functional features of the smartphone.

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 the very loud sound in the 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 a general understanding, I will tell you a few examples.

Example 1. You listen to music on your phone, turn on the 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 become difficult to hear you, this is because in 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 a telephone dialer: enter 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, Alcatel, Philips smartphones

*#*#2846579#*#* – Huawei smartphones

Congratulations, you have entered the engineering menu (Fig. 2). Keep in mind that the menu structure on 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 phone, and you turn on the 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 the end of the phone call, the corresponding files are created in the root directory of the memory card. Their name and structure take the following form: 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.

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, different volume settings (Type) will become available to your view. 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 for the earpiece speaker (the one we put on our 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– adjusting the volume level of the 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.

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 the maximum (I set it to 155, with a 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 that we put to the ear).

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

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 say there is a need to increase the volume level of sound recording when shooting video, then in the 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 to 240 at every level. I remind you to press the (set) button - reboot your favorite gadget and rejoice.

By the way, do not forget to press the “Set” button after each edit of a certain parameter. This action should capture and accept your command. Otherwise, the user-specified parameters are not activated. In addition, a certain number of 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.

Articles and Lifehacks

Just a few years ago, devices with touch screens became incredibly popular. However, many still do not know how to get to the service menu, for example, on 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 its 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, the main feature of the device was still the touch screen, which could be controlled using your fingers rather than a stylus. Of course, even before 2007, unprecedented communicators based on Windows Phone were released, but 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 of a mobile device knows what the service or engineering menu is and what it is needed for. Please note that only experienced users should enter it, otherwise you can 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 runs on Android 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 established itself as a high-quality chipset. 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. The Xperia Z has 2 gigabytes of RAM and 16 gigabytes of built-in flash storage. 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 a 2.2 megapixel front camera (with auto focus and flash function). There is support for 1080p video when shooting at 30 frames per second. The smartphone runs on a powerful and non-removable lithium-ion battery with a capacity of 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 get interesting information about your 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 the following settings to factory settings:
— 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 the 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 take your phone to a 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 displayed 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 the file copy screen where you can make backup copies of 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 WiFi MAC address;
*#*#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.
