Because KaiOS uses Javascript, HTML and CSS in application development, it can directly view the source code, which means that if KaiOS APP is developed, it can only be open source. If Tencent is open source, the consequences will be more serious.

In addition, the operating system of this phone is not mainstream Android or Apple, so it does not support software such as WeChat. If this mobile phone or operating system has a large number of users, it is estimated that Tencent will launch it.

Extended data:

The user interface of KaiOS system is designed based on physical keys and non-touch display screen, while Firefox OS is applied to touch devices. The simplification of Firefox OS makes Firefox OS, an energy-saving operating system that does not require high processor performance, more power-saving and less dependent on hardware after further simplification and optimization.

But even if the system is reduced to this point, KaiOS system still supports 3G, 4G, WiFi, GPS, NFC and so on.
