Let's start

Emergencies:

The emergency number worldwide for mobile is 112. If you find yourself outside the coverage area of ​​your mobile network and you have an emergency, dial 112 and the mobile will search any existing network and seek to connect the appropriate emergency number. The interesting thing is that the 112 can be dialed even if the keypad is locked. Try it!

Are you left the keys in the car?

If your car is safe for remote control and you forgot the keys in it, avoid calling home asking that you bring your second pair of keys. Instead, use your call to ask the person on the line to press the lock button of cars next to the earpiece of your phone, while you stand a few meters from the car door. Your car will open automatically. Already several have tried and it works.

Hidden battery power

If your cell battery is very low and you need to keep an emergency call, press the following digits on your phone: * 3370 #. Your cell will restart with the power of the backup battery showing 50% of energy. The reserve will be reloaded when you load your phone.

How to disable a stolen cell

To check the serial number of your phone, enter the following code: * # 06 #. It will display a 15 digit code. This number is unique to each phone model. Write it down and save it in a safe place. When you steal a cell phone makes a call to your cell phone provider and give them this code. They can crash your computer, even if the thief changes the chip that will go out, because the blockade is the team. It is unlikely that you return the equipment, but at least you will know that you stole it can not use it or sell it.

So you do not detect

So you do not detect when you call the * 31 # and makes the number, or simply put your phone in anonymous. LOL.

Enable HRC (Half Rate Clarity This serves to extend you a little battery life ... but lowers your call clarity so we can help if you need the battery will last a little longer * # 4270 # to deactivate and return to normal clarity * # 4270 *

Current Nokia Software Version, by typing * # 0000 # you will see the following information in your display, the version of software you have, the date on which this software was created and the type of phone you have ... what use is this? if you want to update the software Flashing the phone is better than you know you have that's new.

According to some European news Nokia phones can be configured to locate radar brigades transit. The news outlets to describe how public is hypothetically possible that some Nokia devices through the ringer warn if detect the operating frequency radars. Just another urban myth or any truth?

Then you have to return to the home screen. On display is a radar with five zeros. This trick does not seem to work on all models. According to the news when the phone detects the proximity of a radar ring a bell, like a call, but only a warning radar.

TIPS FOR EQUIPMENT WITH ANDROID:

Restore the

Android requires a Google identity to make the most of the services and applications integration. It is precisely why it is difficult to make changes to an Android phone once configured for the first time. So the fastest way to personalize a mobile operating system is back to its original configuration, but always after making a backup of the content. Restoration happens to go to the Settings menu and then enter Privacy, where is the option to restore factory data.

In that same menu is the option to back up the factory data, which, once activated, use the SD card you want to record important information. That backup is vital, without going any further, when the card is inserted into a terminal in the process of resetting to its original settings, the system will ask whether to restore information from the SD card without the user having to worry about anything else.

Backup all your contacts

If there are data that are really relevant to users, these are the contacts. To back up the same, you only need to go to the Contacts application in the list of installed programs, after pressing the Menu button, choose Import / Export. From here, it will be possible to export the contacts from the phone or Google account. In either case, you get a standard file format. Vcf, compatible with many applications, contact management and addresses.

Defines the keyboard options

One of the most sensitive points in the configuration of a particular terminal and a keyboard is Android. The amount of options available is extensive and not always easy to hit with the best. To configure the keyboard, you only need to bring up the onscreen keyboard and click on the gear, located on the bottom left of the screen.

This displays all related options, where the most significant input text. In this section are the options for automatic spelling correction or prediction, which are not always appreciated by the users. Neither are the vibration when you press a key or make a sound. Remember that in almost all applications, if apaisa the terminal, you pass the compact QWERTY keyboard to full QWERTY text input more comfortable.

Tip 5. Special Characters

Another point not evident nonetheless important is to use special characters keyboard. For the most common, is only necessary to hold down a button for an instant to be despligue a context menu with special characters. Of particular interest are the ñ, accented vowels and symbols in common use. It's a fast and versatile access them without going into specific menus to insert symbols.
There are also other applications for long press, in this case on the screen, interface elements or Android applications. For example, to create a new folder on your desktop, you just have to hold the screen in an area free of icons and display a context menu with various options, among which are creating a new folder or add a widget to access a application or a service.
In general, long press on the screen will cause different actions depending on application and context. For example, on Facebook, in the appropriate application, if you press and hold on the photo albums editing option arises. Do not be afraid to experiment.

USB Mode

When connecting an Android device to a computer, the operating mode of the terminal may be only charging, synchronization with the computer as a disk drive or as a 3G modem via USB cable. The way to change work mode is simple. After connecting the USB cable from your computer to the terminal in the status bar, a symbol with the USB logo. Pulsando sobre él, se abre el menú de cambio de tipo de conexión.

Shortcut on the status bar

The status bar is an extremely suitable to have shortcuts to the most relevant applications of a terminal. However, by default, the system does not install them in a direct way. Fortunately, there are applications like Control Bar to extend the capabilities of Android. Is downloaded from Android Market and is easily installed. Once loaded, you just have to throw it so that you can choose the shortcut you go to install in the status bar. You can choose an application, a service or a phone function, but with the proviso that the icon will not be visible from the application and we will select from a list. It is a lesser evil in any case.

Frees storage space

While not allowed to install applications on SD card, Android, like other mobile operating systems can see much diminished the space devoted to applications and data associated with them. The problem is not so much the programs installed, except to load many, as the space dedicated to the cache or history. Anyway, this space can be recovered from within the Android menu. To do this, one need only go to Settings and look for the section on applications, which in turn is a specific one for administration.
Press Menu, you can specify descending sorting by size, which allows to see what applications are consuming the most space. Clicking on them, there is a menu with things like the space dedicated to data or the amount of memory dedicated to caching software in question. The data erase option is effective, but leaves the terminal without those who have tried more recently, but frees up space if necessary. The cache can be configured within certain limits, so as to spend the least amount possible to save space on the device.
Save battery

If the smartphones have a weakness, that is the battery life. IPhone, Nokia or Android are very sensitive to the use and can happen in a few hours is exhausted the available load for the day. However, there are some steps you can take to improve performance somewhat. The first option is to disable active data network permanently. Under Settings / Wireless & Networks, there is a specific option for mobile networks where the ability to disable the data connection when not needed. In any case, you must be aware of the behavior of applications that connect to the network to verify that they are adversely affected by this change.
Another way to save battery is to use WiFi indoors where 3G networks do not have good coverage. 3G networks are more demanding than the WiFi when consuming energy. Bluetooth is almost always expendable and no reason to keep it active if it is not used. Also a good idea is to disable the GPS if it is not used and, above all, make sure that the widgets on the active screen is not permanently connected to the Internet to find data, otherwise the battery will last (literally) a few hours.

Keyboard Shortcuts

For Android phones with QWERTY keyboard, there are some keyboard shortcuts that they can make using the terminal. Here we collect some of the most practical:

Shortcuts for entering text:

• Copy: Menu + C
• Paste: Menu + V
• Undo: Menu + Z
• Delete character to right: Shift + Delete
• Delete an entire line: Alt + Delete
• Move cursor to beginning of line: Alt + left mouse
• Move cursor to end of line: Alt + right mouse
• Mark text to copy and paste: Shift + mouse right, left, up or down
• Select all text: Menu + A

Shortcuts browser:

• Extension: Menu + I
• Reduction: Menu + O
• Find in page: Menu + F
• Back a page: Menu + J
• Advance a page: Menu + K
• Reload: Menu + R

Secret Codes

Mobile phones often have alternative methods to perform maintenance tasks that sometimes can not be addressed by a software bug in the terminal. For this reason, manufacturers often enable secret codes that allow a restart operation of the device or reset the contents simply by entering an alphanumeric string as if it were to make a call.

The listing of these codes is not easy to collect, although it is always possible to get one of the most used. Here's a miniselección of such codes. Is not safe to work with all devices Android, although in most cases should be operational. To introduce them, you just need to launch the application and enter dial-character sequences specified in each case.

1. The code that enables entry into the information terminal is * # * # 4636 # * # *. Offers a series of advanced information menus of different hardware components. Among other useful details in the information section of the phone,
have available an alternative to disable the phone radio or even to choose the type of wireless network you want to use between WCDMA, CDMA or GSM. The history of the battery is also interesting.
2. The code * # * # 7262626 # * # * activates a screen with different types of test that can be performed on the terminal under the head of mobile communications. There is a risk to the unit tinkering with these options, although this is an appropriate menu especially for expert users.
3. The code * # * # 7780 # * # * is compromised, because with it will be reset to their default values, so it is best used with caution. Anyway, does not work on all terminals with which we have tested.

Screenshot

One of the most serious problems with which you can find a user of Android is to make a screenshot. It seems incredible, but there is no easy to use application that allows for a snapshot. If "rootea" terminal is possible, but done with the root of the phone is not obvious and depends greatly on the device.

However, there is an indirect method through the Android SDK. So the first thing is to reduce your SDK. There are versions for both Windows and Mac or Linux. The next step is to unzip the SDK. For Windows you need to run Setup.exe and select Available Packages / USB Driver Packages. Then, the terminal will be connected using the USB cable Android. The connection mode is not relevant, but choose the source of the drivers if requested by the system, which will android-sdk/usb_driver. Now, just need to run Windows or DDMS ddms.bat Mac in the Tools folder.
If all goes well, will open a window where you only need to select the device is detected, while in the Device menu, you must choose the option to capture screen (Screen Capture). Thus, a window will open with the contents of the Android screen. To get the most current view, you need to press Refresh.

Downloading applications from Android Market

For maximum functionality in a device, it must offer more than just hardware. The applications are a good way to extend the capabilities of the terminal, so that a service like that provided by Android Market is indispensable. The way of working with this center goes through to access your home page and look for the desired utility, or simply explore the categories and programs available. The number of applications exceeds 70,000, so there will be spoiled for choice.

Among the programs essential to Market, we must talk about Google Maps, along with Google Goggles, as representative of what can be done with Google. It is also interesting to have the ubiquitous social networking through Facebook and Twitter, or courier, with the help of MSN Messenger or Google Talk.

Another "classic" Task Killer is a minidesarrollo that performs a cleaning applications and processes running in the background. Sometimes this consumption of resources is undesirable and there comes Task Killer to "kill" the highest rate processes. The tool displays a list of open tasks and a few boxes that can be marked to indicate that you can delete them. It also reports on the available memory and total.

Barcode Scanner Market is another program worth exploring. Allows you to scan bar codes of various types and search the Internet to be identified. At the same time, it is common in the pages of mobility has sections where the links or even the recommended applications for discharge are accompanied by a bar code or QR. If you scan the code with Barcode Scanner, go directly to the link or application.
