What is the third app folder in the Android 4.4.4 card brush package?

Third-party applications are generally optimized by vendors on the native version of Google. Google is one side, and the manufacturer is the other side. If apps from other software companies are preset, this is a third party. For example, Google's native version doesn't have sogou input method, and there is ink weather. Many domestic manufacturers package these two applications, which is the third party.

This is also a big interest chain, especially for products with large shipments, such as Xiaomi and Huawei. If you want to preset popular applications, such as Angry Birds, you have to spend money on other people's game companies. If this application is not very popular, the development company wants to use large shipments to promote it. At this time, the power will be reversed, and the software development company will pay for these shippers.
