Display touch operation

Enable it to display tap feedback when the user taps the screen. A circle appears under your finger or touch pen, and the circle follows you around the screen. It can be used to record video on the device, and a tap acts like a pointer to tell the viewer what to do.

Pointer to the location

After this function is enabled, the pointer position can be displayed on the device with a crosshair. A bar appears at the top of the screen to track crosshairs. When you move the pointer, the coordinates in the bar track the position of the crosshair and the pointer path is drawn on the screen. As shown in the figure:

The drawing paper

Display surface update

All flashes when the surface of the window is updated. The screen flashes every time it refreshes, which is dazzling.

Show layout boundaries

Turn this on to display clipping boundaries, margins, and other interface structures on the device. As shown in the figure:

In fact, this can also be seen a little bit whether the current page is a WebView page, with a WebView loaded page does not have so many lines, is a whole.

Window animation zoom

You can choose pop-up window animation zoom speed, you can also close the animation, all experience can find the animation effect, the lower the proportion, the switch action is more stiff, the animation effect is faster. Select an animation scale of 10x and you will see the dialog that is currently scaled by the selection window pop up slowly.

Overanimate zoom

Almost the same Settings as above, showing the animation effect when switching between pages in the app.

Animation program duration adjustment

Same as above, represents the animation when switching applications.

Analog auxiliary display equipment

Selecting one of these types of devices will create a smaller, simulated display of the same page as the current window on the phone. It’s a little window that shows the current screen.

When half of the screen is broken, but the touch screen still works, open the analog auxiliary display device and you can see the whole screen. 😅

Minimum width

Set to 720dp, the display effect is as follows, to appreciate its significance:

The larger the number, the more content can fit on the screen and the smaller the font.

The default is fine, just fine, if you want to make the font bigger, just make the number smaller. Better not to set too large, font is too small to see clearly. 🤣
