Codes htc desire 600 dual sim. Secret codes for HTC. What are service codes for?

The Android operating system for mobile devices is becoming increasingly popular in the world and is constantly being improved. HTC has also released several models of its smartphones based on this OS, and their number will continue to grow. As for other phone models based on a variety of platforms, there are special service codes for the Android NTS that allow you to get information about the communicator or change its settings.

The following is a non-exhaustive list of service "secret" codes for Android-based NTS with a brief explanation of each of them.

Use these utility commands carefully and only when absolutely necessary. No wonder they are called "secret" and are intended for a narrow circle of service center specialists. Incorrect handling or erroneous input of such a command can corrupt the data stored on the smartphone, disable any hardware module, or reset the settings to factory settings without the possibility of canceling the operation.

Use service codes for HTC Android at your own peril and risk, and best of all, seek help from a specialist.

Questions and comments about secret codes for HTC Desire 600 Dual Sim

Ask a question about HTC Desire 600 Dual Sim secret codes

How to set your own ringtone for ringtone, alarm clock, SMS/messages/notifications?

The ringtone is set in the menu Settings > Sound > Ringtone (green "plus" at the top right).

The melody of SMS and system notifications, depending on the model, is configured in SMS - all messages > menu > Settings > Notifications > Notification sound or in Settings > Sound > Notification sound.

Create folders ringtones, alarms, notifications on your computer. In the first place, place ringtones, in the second - for alarms, in the third - for SMS and mail messages, calendar, etc. Then copy these folders with their contents from the computer to the phone: to the root directory of the internal memory or memory card (if you have smartphone with microSD support). Do not use ES File Explorer, but connect your phone to a computer and copy files through the desktop operating system interface.
The melody may not be visible in the list if the ID3 tags (metadata) in the MP3 file are not encoded in Unicode. You can fix tags with the ID3Fixer program.
Make sure there are no .nomedia files in the specified folders (if there are, delete them).
Restart your smartphone.

The phone itself turns off / turns on, gets very hot, freezes, “bugs”, “flies out” of the programs.

Reboot your device. Important: in the Settings > Power menu, uncheck Fast Boot. Turn off your phone (hold the power button for 2-3 seconds and select Power off) and turn it back on. If the phone freezes and does not respond to anything, hold down the power button for 10-20 seconds - it will reboot.
Boot the phone in safe mode (instruction below) - without autoloading user-installed programs and their services. If the problem in safe mode has disappeared, look for its source in the installed software.
Go to Settings > Apps > All Apps, find the problematic app and tap Clear Data + Clear Cache.
Reset your phone to factory settings (instructions below).
If a full reset did not help, take the phone for diagnostics to a service center.

How to boot in safe mode (safe mode)?

In safe mode, the smartphone will temporarily (until the next reboot) return to its original "factory" state.

To activate safe mode and boot the device in the basic system configuration, restart or turn off / on the smartphone. When Quietly Brilliant appears on the screen, press and hold the volume down key. Wait until "Safe Mode" appears in the lower left corner of the screen and release the key.

The machine returns to its normal state by rebooting (hold the power button and select Restart).

How to do a hard reset to factory settings (hard reset, hard reset, XP)?

Option 1: Settings > Backup & reset > Reset phone.

Option 2: Turn off your smartphone. Simultaneously hold down the volume down key and the power button. A menu will appear, select FACTORY RESET (clear storage) . Navigating through the menu is done using the volume keys, and confirming the selection with the power button.

How to force reboot (soft reset, soft reboot)?

One of two options: hold down the power button for about 10 seconds, or hold it down simultaneously with the volume up key for the same time.

What should I do if the player / media player, the “Music” program spontaneously closes (“crashes”) or does not start?

Try formatting or replacing the memory card (if your phone supports them).
The reason may be a corrupted media file or a long/incorrect file name. Delete the entire music collection and re-record it one folder at a time. This will locate the problematic directory/file.

The camera turns off and does not work: the screen is black / the image is still, the camera closes.

Reset camera settings: Settings > Apps > All apps > Camera > Clear data + Clear cache. Restart your smartphone.
Restore the camera to factory settings: In the camera interface, press the settings button and select Factory settings.

Why are some contacts' photos blurry as if covered with a grid?

Photos of these contacts are of low quality (they have low resolution). On a computer, via Google Contacts (in Gmail), transfer contacts to the Starred in Android group (or transfer them to the Favorites group on your phone) and set new high-resolution photos for contacts.

How to open the "For Developers" menu?

In the system settings, go to the menu About phone > Software version > Advanced and several times (seven or eight) quickly click on the Build number line. You will see a message about activating developer mode. The item For developers will appear in the settings in the "System" section.

How to transfer a program or game to a flash memory card?

Settings > Applications > , select an application, press the Move button (for previous versions of HTC Sense: Settings > Applications, SD card tab, select the Move to SD card checkbox; the same tab shows what programs you have installed on the card).

Keep in mind that not all HTC programs and models support transferring to a memory card!

Why can't I save or copy files to a memory card (ext_sd)?

In Android 4.4 and higher, the way programs work with a memory card has been changed. Now programs (including file managers and browsers) can only write data to their own folder on the map (Android / data / program-name), and not to an arbitrary one. Therefore, write (copy, move) files to the memory card not from the phone, but from the computer by connecting the phone to it.

Poor connection, internet. The phone loses the network. The interlocutors complain about the loss of sound during a conversation, insufficient audibility, echo, "gurgling", "croaking".

The vast majority of problems are related to the network of the telecom operator and the range of the network. Therefore, the universal way to diagnose and fix such problems is to change the network mode. We recommend setting the GSM-only mode (complete shutdown of 3G).

Options for changing settings:

Settings > Mobile Internet > Network mode (“Auto GSM/UMTS/LTE”, “Auto GSM/UMTS”, “UMTS only”, “GSM only”).
Dial in the phone interface *#*#4636#*#* > Phone Details > Set Preferred Network Type.

Other options for solving communication problems:

Turn off mobile internet.
Do not cover the speaking microphone with your hand/finger.
Replace the SIM card with a new one (especially if you received a SIM card for a long time) or change a standard SIM card that you cut off with your own hands to a micro-SIM.
Change operator.

How to view a list of recent programs (open Task Manager)?

To open recently launched apps, double-click the Home button. The behavior of this button is configured in Settings > Display, buttons and gestures > Home screen.

How to remove the "three dots" (line with three dots to open the menu)? How to call the menu if there is no such button?

Go to Settings > Display, buttons & gestures > Home screen (Home button) - tick the bottom radio button. The application menu will start to open with a long press on the "Home" button, and the strip with a vertical ellipsis will disappear from the interface.

Why does the amount of (RAM) memory in the system properties not match the declared one?

Part of the memory is used by the Android operating system, HTC Sense and other service components. The user always has less memory available than indicated in the characteristics of the phone. .

The “Others” item in “Settings” > “Phone memory” includes operating system files, system programs, files and drivers necessary for the operation of connected devices, and navigation software maps.

How to turn off the BlinkFeed news screen?

HTC Sense 5.5 has a built-in BlinkFeed disable feature. BlinkFeed is disabled in Sense 5.0.

How to take a screenshot of the screen?

To take a screenshot on HTC, hold down the power button and, without releasing it, press the Home touch key once. Second option: power button plus volume down key.

The screenshots will appear in the Screenshots album (Gallery > My Photos). They are physically located in the pictures > screenshots directory.

Why can't I copy, move, delete files (photos, videos, documents) on an external memory card in Android 4.4.2?

Starting with Android version 4.4.2, only regular programs (such as Gallery) can save files (and delete them) to a memory card (in an arbitrary directory). This is Google's policy. Third-party programs have write permissions only to their own folder on the card (Android / data / folder-programs).

Wi-Fi Direct enables direct communication between phones that support this technology without connecting to a Wi-Fi network (no wireless router required). Wi-Fi Direct is enabled in Settings > Wi-Fi > Menu > Wi-Fi Direct. We recommend using SuperBeam to send files quickly.

How to display image from HTC phone to external display?

Why does the phone not see the flash drive via OTG / memory card?

Try another cable.
Format the flash drive/memory card to create an exFAT or FAT (not NTFS) file system. FAT32 is used in microSD, microSDHC cards, and exFAT is used in microSDXC cards.

Contacts, phone book, SMS, messages

Notifications come from number 50 in the form of SMS with the name of the region in which the phone is located (it is proposed to save or cancel). The salon said that this is a problem for many HTC owners. Is there any solution to this problem?

1. Settings > Call settings > uncheck Broadcast message reception under Other call settings. The option may also be called "Get a list of channels" (uncheck the box and delete all channels).

2. If this item is not available in your phone settings (for example, in Desire 600 or One Dual SIM), install the SIM card in another phone (relatives, friends) and turn off broadcast messages through the SIM card menu (turn off channel number 50).

3. Contact the service center of your mobile operator and replace the SIM card (new SIMs do not have broadcast channels configured).

4. Install the Blacklist or Blacklist+ program and add the number 50 to the blocked list.

How to block (blacklist) a contact to receive incoming calls and SMS?

Hold your finger on the contact, select Block contact from the context menu. You will no longer receive call and SMS notifications.

You can remove a contact from the blocked list on the Call Log > Blocked Contacts tab. Tap and hold a contact, then select Unblock contacts.

How to set up MMS?

Settings > Mobile Internet > Slot #1 or #2 network (Dual SIM models only) > Internet hotspots. On the APN screen, press the settings button and select Create APN. Find MMS settings on your operator's website.

Example for MTS:

Name: MTS-MMS APN: mms.mts.ru Username: mts Password: mts MMSC: http://mmsc MMS proxy server: 192.168.192.192 MMS port: 9201 MSC: 250 MNC: 01 APN type: mms

Why are there two "Contacts" items in the settings, in the "Accounts and sync" menu?

"Contacts" is present twice in Android sync settings due to translation errors. In the original, it says Sync Contacts (synchronization of Google Contacts) and Sync People details (synchronization of people from Google+ circles). We recommend disabling the "lower" "Contacts" if you do not actively use G +.

The phone stopped receiving SMS, although it sends itself. The phone stopped sending SMS from one of the SIM cards.

Check if the SMS center number is correct (Messages > Settings > Text messages (SMS) . Sometimes it is erased. It also helps to save the SMS center number again.

Check that the SMS Center is listed for both SIMs (for dual-SIM phones).

How to set a ringtone for a specific contact in HTC?

There are three ways:

In the music player, click on the menu (three dots to the right of the ringtone name) and select Contact ringtone.
In the phone book ("Contacts"), open a contact, click Ringtone (by default) in the Options section, in the window that opens, click the "plus" button in the upper right.
A method that is suitable for budget models without a full-fledged HTC Sense and without the “contact ringtone” function: add a contact to a separate group and then set a ringtone for it.

How to assign a ringtone to calls to a specific group of contacts?

Open an arbitrary music composition from the Music folder in the media player, press the "menu" and select Set as contact melody, enter the name of the contact group for which you want to assign a melody in the search bar, mark all found contacts and set the melody.

Why is the contact not visible in the phone book and not found by search, although it exists?

When saving a contact, specify the Google type. In "Contacts" at the top left, select "Phonebook" and check the boxes on the desired items (in particular, Google).

Marriage, defects, "glitches"

I hear a lot of noise during a conversation and in the recorded videos, what should I do?

Clean the openings of the speech and noise microphones with a needle.

Why are there clicks in the speakers?

BoomSound amplifier turns on and off. It is impossible to eliminate these clicks.

What to do if the mobile Internet is lost?

This happens sometimes. Turn on/off Airplane Mode or reboot your device.

How to fix if the SIM card periodically turns off / “falls off”?

Check if the SIM disconnects are due to case deflections near the SIM card slot. If this is the reason, make (of electrical tape, cardboard, plastic) pads around the slot that will prevent the back cover from pressing on the slot.

For phones with a micro-SIM card type: replace the card that you cut yourself with a new micro-SIM at your service provider.

What are service codes for?

As for smartphones from other manufacturers, there are service codes for smartphones manufactured by HTC. They allow you to view information about your smartphone, test some of its functions, and change settings. Basically, these service, or as they are called secret codes, are necessary for engineers and technicians who repair phones, but they are also useful for ordinary users. But input should be done with extreme caution, as incorrectly entering the service code can damage an expensive gadget.

Service codes

When you enter the code *#*#4636#*#*, the communicator will display full information about it, as well as statistics on its use. If desired, you can view the battery status.
By entering the code *#*#7780#*#*, it becomes possible to reset all your settings and restore the factory settings. Resetting the factory settings will delete all system settings, as well as application settings that are installed on your device. The settings of the Google account and applications that are downloaded to the communicator will also be deleted. Factory reset will not only delete user files stored on the flash drive.
When you enter the code *2767*3855#, the communicator firmware will be reinstalled.
Entering the code *#*#34971539#*#* will allow you to update the communicator's camera firmware from a memory card, as well as view the number of firmware updates. When you turn off the HTC communicator, a menu appears on the screen where you can select the operating modes of the communicator.
If there is a desire to turn off the phone immediately, when you press the "End call" key, then you must enter the following code * # * # 7594 # * # *.
When you enter the code *#*#273283*255*663282*#*#*, you go to the menu for copying files. Here you can back up audio, video files, as well as pictures and photos.
Entering the code *#*#526#*#* will start the WLAN test.
If you enter the code *#*#232338#*#*, then the WIFI MAC addresses will be displayed on the screen of the HTC communicator.
To test the GPS, you will need to enter the code *#*#1472365#*#*.
To test Bluetooth, you will need to enter the code *#*#232331#*#*, and in order to see the Bluetooth addresses of the device, you need to enter the code *#*#232337#*#.
In order to call the GTalk service menu on the HTS communicator, you will need to enter the code *#*#8255#*#*.
To view the FTA SW and FTA HW versions, you will need to enter the codes *#*#1111#*#* and *#*#2222#*#* respectively.
To get service information about PDA, Phone, H/W, RFCallDate dial *#*#4986*2650468#*#*.
To get service information about PDA, Phone, CSC, Build Time, Changelist number, dial *#*#44336#*#*.
When you enter the code *#*#0*#*#*, a screen test will start on the HTC communicator.
When you enter the code *#*#0289#*#*, testing of the audio path will start.
To test vibration and backlight, dial *#*#0842#*#*.
To test the touch screen, enter *#*#2664#*#*.
To test the proximity sensor, enter *#*#0588#*#*.

An engineering code (secret code) is a sequence of symbols and numbers designed to fine-tune and control a smartphone under the Android OS.

Engineering codes allow you to perform those settings that are hidden from the settings of the smartphone itself.

There are universal engineering codes that are suitable for almost all Android OS devices, but there are also those that work only under a specific OS version and a specific smartphone model.

Important information

Often on the Internet, in the topic about engineering codes, you can find a warning that when using codes, you risk breaking the device, etc.

However, this is slightly exaggerated, since in the worst case, you risk losing your personal information on your smartphone and no more, for example, when you run a command designed specifically to reset the settings and then delete personal data.

Therefore, before using the codes, it is still better to backup all important data. And remember that you act solely at your own peril and risk. The author is not responsible for the incorrect application of the knowledge gained in this article.

How codes are activated

Special codes are called quite simply. To do this, just open the dialer program, i.e. standard "dialer" and dial the desired code. After that it will work. You don't need to download additional programs.

General codes

Let's look at common engineering codes, if you can call them that. Let's start with a simple combination:

*#06# - shows your phone's IMEI.

This combination is known to everyone and perhaps many will not agree that this is an engineering code, but we will attribute it to engineering codes. Agree, because a simple user does not always suspect the existence of some kind of "IMEI" and does not even know what it is, let alone how it is called.

This code will work on all devices, regardless of the operating system and phone model.

Not a lot of course, but at the moment I can’t even remember at least one more universal code that works on all devices.

This ends the universal codes, and we turn to the consideration of codes that work specifically on HTC Desire 601.

Codes for HTC Desire 601

Now we will look at the engineering codes that work on the HTC Desire 601 smartphone. With a certain degree of probability, these codes will work on other Android smartphones as well. So don't be surprised if the codes below don't work on your device.

*#*#3424#*#* - launches "HTC Function Test", designed to run a phone test. A kind of smartphone diagnostics that allows you to check the operation of the network, screen, speakers, etc.;

*#*#4636#*#* - launches the "Testing" window, which allows you to check the network performance on the device;

*#*#8255#*#* - launches "GTalk Service Monitor", which allows you to check the operation of the messaging service;

*#*#426#*#* - launches the "Google Play Services" mode, which allows you to check the performance of Google services;

*#*#759#*#* - launches the "Google Partner Settings" mode, which allows you to start monitoring work with the Google Partners program;

*#*#1234#*#* and *#*#7873778#*#* - launches the installed SuperSU program;

*#*#2374#*#* - switches between conditional and active redirects (CFU query when camp-on is off/CFU query when camp-on is on);

*#*#856682583#*#* - starts the debug mode of the VKontakte application.

This concludes the list of working service codes for the HTC Desire 601 smartphone. Of course, certain codes can work in one version of the Android OS, and not work in another version. It all depends on the operating system version and phone model.

conclusions

Thus, we learned about what engineering codes are and what they are for.

Skillfully using the above engineering codes, we have an additional tool for debugging and testing the functionality of our HTC Desire 601 smartphone.
