Secret codes for HUAWEI Ascend P6-U06 (White). Huawei P6 problems and how to fix them Editing modes in the engineering menu

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.

Questions and comments about secret codes for HUAWEI Ascend P6-U06 (White)

Ask a question regarding the secret codes of HUAWEI Ascend P6-U06 (White)

In general, if you have an Android smartphone Huawei P6 (or another Huawei from the same generation), and suddenly “something wrong” begins to happen to it (or for some reason you have a suspicion that something is wrong with it) “something wrong” is happening), just determine what this “wrong thing” looks like and find a similar symptom in the following list.

Huawei P6 battery problems

(the smartphone is connected to the charger, the charger is connected to an outlet, but the battery still does not charge)

Options:

• socket is faulty (sometimes it happens that the socket does not work well due to worn contacts, poor connection, etc.) - try connecting the smartphone to another socket, if the battery starts charging, then the problem is not in the P6;

• charger cable damaged (standard microUSB cables often break) - you need to find a working cable and try to charge the device through it;

• battery is faulty - in this case, the smartphone, as a rule, functions properly when connected to the charger, but does not work or does not work in offline mode for long; the problem can only be solved by replacing the battery.

Huawei P6 problems - micro-USB port is not functioning properly

Most often this happens if dirt, dust and other unpleasant substances get inside the connector. First of all, try to bleed the port. If you still notice any foreign particles in it, carefully remove them, for example, with a toothpick, and then blow out the port again. If the port does not work well after this cleaning, check the microUSB cable.

Huawei P6 has problems connecting to the Internet (or mobile network or Wi-Fi)

Options:

• Airplane mode activated , which provides for disabling built-in wireless communication modules, i.e. Internet access, Wi-Fi and your mobile operator's network. Often, users turn on airplane mode by accident or forget that it was turned on. Check out the "flight mode" in your Huawei P6 ( Settings -> Airplane Mode -> Off).

• you are in the zone of so-called uncertain reception mobile operator signal
  This also happens quite often, especially in areas remote from large populated areas. Pay attention to the smartphone's connection quality indicator. If it shows the minimum level, then it is better to move somewhere higher and/or go to a more open area.

P6 from Huawei speaker problems

(during a telephone conversation the speaker does not produce sound)

Options:

• turned off and/or volume reduced to minimum — check the volume settings. If the volume does not increase, check the control button on the body of the device - it may stick or break from prolonged use. Gently move it with your finger from side to side; if you notice that it moves poorly, it is better to contact service. In addition, the internal microswitch can also break, which can only be repaired or replaced by an experienced technician (all about Huawei P6 repair)

• speaker doesn't work (sound does not play) - most often the cause may be mechanical damage resulting from the smartphone being dropped on various surfaces or being used for a long time. A failed speaker must be replaced.

Huawei P6 screen problems

(display does not work correctly: does not turn on, dead pixels, only one color is displayed, limited number of colors, shifted image, touch panel does not function, etc.)

Options:

• brightness has dropped — in certain modes, the smartphone can automatically reduce the screen brightness; go into a dark room and turn on the device, if the image on its screen is readable, then simply double-check the brightness settings;

• battery is low - and the smartphone turns off, connect it to the charger, if after some time the P6 does not turn on, check its battery (see above);

• protective glass of the screen is displaced
  If the Gorilla Glass on your Huawei P6 is not flush with the LCD display, there may be debris on the protective glass floor. Gorilla Glass must be removed, cleaned, and reinstalled correctly. It is better to do this in a SC environment.

• protective glass is damaged
  If your smartphone has been dropped and cracks, chips or scratches are clearly visible on the Gorilla Glass surface, this is also a reason to contact a service center. Damaged glass must be replaced.

• LCD display damaged
  ... change!

Huawei P6 camera problems

(poor quality or “black” photos)

Options:

• The camera is covered by a case - this happens with low-quality and/or “foreign” accessories that fit in size, but were originally developed for other smartphones. Such a case may partially or completely cover the lens of the built-in camera, with corresponding consequences for the quality of images.

• the shutter doesn't work - on the P6 (as well as on many other smartphones), the shutter of the main camera can “jam” after too active and/or prolonged use; the problem can only be fixed by replacing the camera.

• lens is broken or dirty — due to improper care, dust and dirt particles accumulate and gradually forget about the lens. If this happens, the device must be disassembled and cleaned. If the lens is damaged, the camera must be replaced.

Huawei P6 locking problems

(lock button doesn't work)

• smartphone frozen - this can be due to too many simultaneously running applications, or due to overheating from prolonged active use (usually with gaming applications); if the screen and volume button stop responding, wait 5-10 minutes; if the system works again, disable all unnecessary applications, otherwise remove the cover, remove the battery for a couple of minutes, then reinsert it and turn on the smartphone.

• lock button stuck - most often due to wear or mechanical damage, gently move it with your finger; if you do not observe the desired effect, the smartphone should be taken to a service center.

P6 from Huawei touchpad problems (not responding)

Options:

• smartphone frozen - see previous paragraph

• digitizer damaged — if the phone was dropped on a hard surface or strong pressure was applied to its screen, then the digitizer is most likely damaged, in which case it needs to be replaced.
