Introduction of mobile phone buttons

Mobile phones, called mobile phones or wireless phones, are usually called mobile phones. At first, it was just a communication tool, commonly known as "mobile phone" in the early days, and it is a portable telephone terminal that can be widely used. The following is the introduction of mobile phone buttons that I have compiled.

Introduction to mobile phone keys 1 Huawei U88 18/Ascend G300 practical tutorial/thread-1062022-1.html This setting method is applicable to all Android phones, including U8860. * First of all, the mobile phone must have ROOT permission. How to get ROOT permissions is not much to say here. See the tutorial:/thread-10974808-1-1.html Install an R&E manager (usually with its own ROOT. If you don't click here to download: /thread- 10978989-65438+. Click the switch button of read-only rewrite above to change the current mode to rewrite, then enter the directory of /system/usr/keylayout, press and hold the qwerty.kl file on the touch screen, and select the text editor mode to open in the pop-up menu. Editing the contents of this file can change the function of each key on the mobile phone. For example, modify the "search" key to lock the screen, which is equivalent to the function of the power key. You can modify:

Keyword 2 17 search

Replace with:

Key 2 17 power supply

Of course, you can also modify it as follows:

Key 2 17 Power Wake _ Drop

It can be changed to this:

Key 2 17 Power Wake-up

Why can there be so many changes? Look at the following explanation and you will understand!

The following are the differences between WAKE and WAKE_DROPPED:

Wake-up means to wake up (activate the screen) and send a request.

WAKE_DROPPED means to wake up (activate the screen) without sending a request.

To make it easier for you to understand, I'll give you a detailed example:

102 HOME button (HOME home button can only be pressed when the bright screen is unlocked, otherwise there is no response when pressed).

102 HOMEWAKE key (the homewake key can be pressed when the machine is not awakened, and the machine is awakened after being pressed, and the button event of this key can be submitted).

Key 102 homewake _ dropped (if the machine is not awakened, click to wake the machine first and then click, and then submit the button event of this key).

The number behind the key indicates the physical code of the key, and the English at the back indicates the name of the key function in the Android system, so we only need to modify the physical code of the key and the English name of the corresponding key function.

For example, if you change the function of the home button to a photo button, you can make the following changes:

Key 102 was changed to: key 102 camera.

Can be used flexibly by analogy!

The following are some basic function keys corresponding to common key codes by default:

102 HOME key returns to the main desktop key (the key of the house icon).

12.*2767*3855# Samsung chip reset can also be explained by unlocking or locking: chip reset is actually similar to the function of soft and hard cells. The command instruction is *2767*3855#, which has no effect on the mobile phone hardware, but will reinstall the software. After the chip is reset, there is no different influence on parallel imports. Chip reset is actually when the mobile phone has more software, or when it is a mobile phone. There are serious software conflicts, which slow down the running speed of mobile phones. It can also be used as a method to unlock and restore the original state after forgetting the lock code. After the chip is reset, it has the following effects on (it can be used by itself if necessary without reset test):

1, the first is the SMS and phone book stored on the mobile phone. No matter how much you save, once you use this instruction, 1 second is wasted. So this command can be used to quickly delete the phone book and text messages on the mobile phone.

SMS and MMS: Not only the SMS in the SMS inbox is gone, but also the preset information list and voice mail number, but the MMS inbox is useless.

2, call records: all empty numbers! Including all call duration records, are all zeroed.

3. Ringtone setting: All the bells are restored to the factory status.

4. Display screen settings: wallpaper, text display, menu style, automatic keyboard lock, background light, etc. All returned to the default mode, and the greetings were gone.

5, security settings: first of all, the phone password is gone! Back to the initial 00000000, the password verification of setting the mobile phone also failed. But it has no effect on the pin code of the sim card, and the sim card lock is still valid. Therefore, you can use this command to retrieve the forgotten phone password.

6. Other settings and shortcut keys have been restored to the factory status.

7. Manage the directory: the alarm clock is gone, and the recording and notepad are empty, but the time and date need not be reset.

8. Entertainment function: This has hardly changed. The favorites of wap browser are all there, and the ringtones and pictures downloaded by mobile phones are also intact. Thirteen. *#0228# Display battery information.

Fourteen *#9990# Turn off Bluetooth connection

Introduction to mobile phone keys 3 1. Get the serial number.

Because there are too many kinds of mobile phones on the market now, it is easy to confuse the fish with the pearls. Anyway, we ordinary users can't distinguish them with the naked eye. However, mobile phones have serial numbers, and each mobile phone corresponds to a number, which is not repeated, so we can know whether we bought "parallel imports" through it. We can enter: * # 06 # in standby mode, and the serial number of the mobile phone will appear on the screen, then open the back of the mobile phone and take out the battery to see if the serial number matches the serial number on the internal label of the mobile phone. If not, we should contact the seller.

2. Confirm the password.

When using the mobile phone, we need to use the "#" key to confirm the password input. For example, when we check the phone bill, we must enter the password of the mobile phone, and then we must end with the "#" key. PIN, PIN2 password and SIM card password in mobile phones usually end with #.

Find the specified location

Most users have a phone book in their mobile phones to store commonly used phone numbers, and each phone number will occupy a specific position (just like a seat in a cinema). Sometimes it is necessary for us to know who the users are in a specific location. Generally speaking, we will enter the "Phone Book" menu first, then select "Search by Location" and enter the location before we can see it. In fact, the author has a very clever method. As long as we enter a location number, such as 12, and then press the # key, the user name with the phone book number of 12 will appear on the screen, and then dial the user by calling.

lock the keyboard

Because some mobile phones have no flip cover, it is easy to touch something in your pocket and answer the phone automatically. Or to avoid this situation, a good way is to lock the keyboard. If you can lock the keyboard by holding down the # key on Siemens mobile phone, then you can hold down the # key on Motorola mobile phone at the same time.
