Android 4.4 not only brings us the ART mode and a more concise UI layout, but also brings an important new feature "immersive full screen". In applications that support this specification, the virtual key will be automatically hidden (of course, the mobile phone itself uses the virtual key). But for some applications that do not conform to this specification, do we have to tolerate virtual keys occupying our screen space? This time, we introduce an application called Immersive Mode to solve this problem.

The following screenshot is from HTC's new flagship M8, which uses the latest Android 4.4 system. It is also a mobile phone that uses virtual keys.

What does immersion full screen mean? As we can see from the figure below, applications that support immersive full screen will automatically display full screen on Android 4.4 phones, without annoying virtual keys ▼

When we need a virtual key, we can call up the virtual key by gently sliding it at the bottom of the screen, and the virtual key is displayed in a transparent state ▼

Let's first take a look at the situation when M8 uses third-party applications under normal circumstances. The following screenshot is Weibo. The virtual key plus the function classification of Weibo has two layers. If you add the original "double chin" of the body, you can't bear to look directly ▼

Open Immersive Mode. The menu of the application is very simple. Although it is in English, I believe these words are easy to understand. The first switch is to open the global immersive full screen ▼

After opening, the effect picture is as follows. At the same time, we can see that the application supports hiding ▼ of the taskbar

Blacklist can be set separately for an application ▼

We use the Temple Escape as a demonstration. Under normal circumstances, virtual keys will be displayed. This game does not support immersive full screen ▼

Open Immersive Mode, and ▼ will be displayed in full screen normally

With a slight stroke at the bottom of the screen, the virtual key will call out in a transparent state, without affecting the original function ▼

From the above trial, we can see that Immersive Mode can still bring a lot of convenience to some Android 4.4 phones, but it also has a big defect that when the immersive full screen is turned on, input method cannot be used. For users who like to watch e-books and play games, this application can play its best role.
