Why Android is not as smooth as IOS?

Although many Android phones have higher configurations than the iPhone, for example, most Android phones have 1 GB of memory, while iPhone 4S only has MB of memory, however, people who have used the iPhone know that Android phones are not so smooth when used. Why does this happen? A software engineer and former Google Intern Andrew Munn explained that the problem was caused by the Framework Design of the Android system UI.

In iOS, the UI rendering process has an absolute priority level. When the user is exposed to the iPhone touch screen, all the processes in IOS will be stopped, and the system will use all the resources for rendering the UI process. In the Android system, the priority of the UI rendering process is not so high. That is to say, when you touch the Android mobile phone screen, the background program of the system is not stopped and is still running, for example, you can download and retrieve text messages so that the system UI does not have enough resources. This is why the Android system is not smooth.

For this reason, the newly released Galaxy Nexus, or even a quad-core processor, means that eeepad Transformer Prime tablet cannot guarantee smooth operation experience, these devices can only be smooth compared with the iPhone 3 years ago. Why does the android team not fundamentally solve this problem?

In fact, Android development started before the first generation of the iPhone was released. The original Android prototype was designed as a device using a keyboard and mobile phone, that is, a competitor of blackberry. Ui rendering priority is not that important on a mobile phone with a keyboard. However, after the release of the iPhone, the android team quickly changed android to a touch screen mobile phone system to quickly launch products that can compete with the iPhone, but it was impossible to rewrite the UI framework at that time. As a result, all applications in the Android app market will become unavailable, and this relationship will remain in a vicious circle. It's no wonder that Steve Jobs said in his biography that android is a stolen product, and even Apple will destroy it.
