Android u8800 long press the search key, Return key lock screen, or unlock settings

This setting applies to all Android phones, including u8800.

 

* First, the mobile phone must have the root permission. We will not talk about how to obtain the root permission. Generally, install a root software.

 

Install an R. e Manager (root Explorer), run r. E Software, click the read-only and rewrite button above, change the current mode to rewrite, then go to the/system/usr/keylayout directory, and press qwerty on the touch screen. open the KL file by selecting the text editor in the pop-up menu. edit the file content to change the function of each button on the mobile phone. For example:

 

Modify the "Search" key to lock the screen, that is, the black screen function equivalent to the power key. You can modify it:

Key 217 search

Changed:

Key 217 power

 

Of course, you can also modify it to the following:

Key 217 power wake_dropped

 

You can change it to the following:

 

Key 217 power wake

 

 

Here we will talk about the differences between Wake and wake_dropped:

Wake indicates to wake up (activate the screen) and send a request

Wake_dropped indicates waking (activating the screen) without sending a request

 

For your convenience, I will give an example:

Key 102 home (the home key can be pressed only when the screen is unlocked; otherwise, no response is received)

Key 102 home wake)

Key 102 home wake_dropped)

 

The number after the key represents the physical encoding of the key, and the English behind it represents the key function name in the Android system. Therefore, we only need to modify the physical encoding of the key and the English name of the corresponding key function, you can. For example, if you change the Home key function to the photo button, you can modify key 102 home to key 102 camera.

The common key encoding function keys are as follows by default:

Key 102 Home Return primary desktop key (House icon that key) key 139 menu key 158 back return/Return key 217 search key 107 endcall end key 116 Power key 212 Camera photo key
