What operating system is Hisense led50k20jd? Is it Android?

Hisense led50k20jd's operating system is a vision system based on Android 4.0, which has been redeveloped. Generally speaking, Android 4.0 system is used to simplify and optimize TV sets. You can remove some unnecessary functions on TV (such as touch screen function), and then add some TV-specific functions (such as remote control support). Because these optimizations were made by Hisense itself, the system was named after a makeover, which is the visual system. In fact, this system is just a special human-computer interaction interface for smart TV. It has only one kernel, which is an Android kernel, which is very different from the Android system on your mobile phone or tablet.

Most other smart TV manufacturers also have their own operating systems, which are suitable for their own products. In addition, although these systems are all Android kernels, it doesn't mean that the software on your Android phone can be used directly on TV. Some machines can work, but some cannot; Maybe some software can, and some software can't. It depends on what changes they made during the optimization process.
