The watch doesn’t support always-on display but, supports feature turn on-screen every time you turn the arm towards yourself. And unfortunately, it takes about many seconds for the screen to come on every single time you rotate your wrist, and then you have to wait up to 2 seconds for the screen to come on. I wish that would have been faster because it is may cause inconvenience to some people.

We recommend deactivating the automatic ignition when turning the wrist If you want to conserve battery life for a longer period of time, And you can press a button to turn on the display, Other than that the screen is going to stay off at all times?.

Watching videos

Watching videos on this little screen isn’t ideal because the screen is very small, not to mention the screen is around and most applications aren’t actually designed for round screens.

Writing on screen:

If you’re going to type on this screen, the letters are very small. You may find yourself typing the same letter twice on multiple occasions. So there are some limitations due to the size and around the screen.

Performance of KOSPET Prime 4G:

KOSPET Prime 4G can easily handle multiple tasks simultaneously and ensure quick launch, as it is a compact smartphone in your wrist. Thanks to its powerful MTK6739 4 Cores 1.25GHz processor that makes sure the device delivers high performance, Added to this are 3 GB of RAM and 32 GB of storage space. which is quite enough for daily use.

The operating system:

The KOSPET Prime 4G works on Android version 7.1, it has a good interface that is easy to navigate and smooth but, there are some delays if you scroll from the main screen to the main menu. The rest of the user interface is pretty fast and operates without any problems.
And the OS allows you to install almost any application and game from the Google Play Store. I did not find any performance issues and apps ran smoothly. Also, The device synchronizes with an application called WiiWatch 2 to access several sections, and have an overview of your activities, in the Health section, the graphs of physical activity are shown and in the Mark option, It supports both the Android and iOS devices on iOS 9.0 / Android 5.1 or above.

It is very simple to switch in between watch faces. You hold your finger pressed on the screen and then you can change the watch face. You can also install other watch faces – there are 11 available.

Also, You can choose the menu interface between two choices. The first one is the generic, scrolling menu that’s present in most similar devices or between the more appealing to me, like that of the Apple Watch’s bubble-styled apps display. And because there are several options for the menu and even the faces watch, I guarantee that you don’t boring about this smartwatch, right?
