This is the decompiled source from /system/framework/wifi-service.jar in Samsung Galaxy Note-10+ Phone (Hong Kong version), as at Sept 2020.

The background decompiling this source code is that it contains evidence that the code, without knowledge of its owner, forcibly add a new public DNS server, 114.114.114.114, controlled by Cogent Communications, under Nanjing XinFeng Information Technologies Inc, in Mainland China, when the device is operating in Hong Kong (as well Macau / Mainland China), and use the server to resolve www.qq.com, a domain owned by Chinese tech giant Tencent.

This has caused privacy concerns for some users in Hong Kong. I claim fair use for posting this copyrighted work, for the purpose of criticism, comment, news reporting, and research concerning the Samsung phones.
