Currently, the following mobile phone operating systems are common: A. symbiain Operating System
Including Symbian uiq, s40, s60 2nd, s60 3nd, s60 5nd, S80, and S90. Among them, s40 is a non-intelligent machine system dedicated to Nokia. Due to the high coverage rate of Nokia, therefore, it is often listed. The uiq system has stopped development, and S80 and S90 are only used on a few models, such as the previous high-end 9 series, 7710 and other mobile phones.
Currently, the s60 system, which is common on the market or mainly covered by mobile client development, includes the second and third versions. These versions also include FP1 and fp2. fp indicates Feature Pack.

B. Windows Mobile operating system
If I didn't understand the problem, Windows Mobile's predecessor was a messy collection of pocketpc, smartphone, and so on. Now it is integrated into Windows Mobile.
This series also has different versions, but like Windows, it is basically backward compatible. Unlike Nokia's operating systems, there is a big difference between different versions.
C. Windows CE operating system
Qepai in China and meizu M8 all adopt Windows CE systems. Windows CE systems are relatively more customized, but the current market coverage is relatively small.
D. iPhone OS Operating System
In recent years, Apple has developed an iPhone operating system based on its experience in Mac OS X, a PC operating system. Currently, this operating system is unique and has no semicolons.
Its core is the Linux system.
E. Blackberry operating system
The operating system used by Blackberry seems to have only been introduced by China Mobile in China. The rest are both parallel imports, which are highly cost-effective.

K. Mobile Phone System of Zhan Xun
Similar to above, it is actually a platform, which is a mobile phone solution.
I. kjava
This should be regarded as an environment. In addition to the development environment, many systems also provide a Java environment and can develop applications. Many non-smart machines also provide Java environments to install software.
