Android developer mode
Posted by: 13.05.2018
The popular operating system for Android mobile gadgets has extensive specialized functionality that is used by programmers and application debuggers, equipment testers, as well as advanced users who want to get the most from their device. In particular, the OS provides the ability to display the workload of the processor and memory module, record statistics on the use of individual processes and programs. You can also simulate the screen in a variety of resolutions and color schemes, which becomes a real lifesaver for site testers and other professionals responsible for the convenience of working with applications and network resources. To gain access to such options, you need to enable Android developer mode.
How to do this, as well as how to turn off this environment, we consider in detail below. The described actions will be identical for almost all devices running Android, whether it is a top-end smartphone from a well-known brand or a simple and cheap handset from a little-known one.
How to enable Android developer mode?
To gain access to the engineering functionality of the OS, you must perform the following steps:
- Open the menu "Settings"On your gadget and scroll it to the bottom of the"About the device". Depending on the type of platform, it may be called “About phone"Or"About tablet».
- We click on the corresponding menu block, after which a window opens where the main parameters of the device are given: its model, technical parameters, OS version and other important data.
- Find the item "Build number"(On devices from Xiaomi it is called "MIUI version") And several times click on it several times. After that, the message “You're almost there!"Indicating the required number of clicks on the assembly number.4. We continue to press until the message “You have become a developer!, Which confirms that Android Developer Mode is running.

Android Developer Menu - Hardware Acceleration of Visualization Effects Sector
Here implemented tools such as:
- «GPU Acceleration"- when you run this option for 2-dimensional graphics, the default GPU resource will be used.
- «Screen refresh"- if this item is enabled, then when the image is drawn on the display by means of the GPU, it will be highlighted.
- «Display hardware updates“- using this tool will provide a highlight of hardware updates.
- «Debug overlays»- using this option you can customize the display of screen overlays.
