114本身for大陸地區 但寫firmware條友柒咗 當埋香港係大陸
Samsunghk又唔知加咗啲咁嘅嘢 照出個firmware

因為114 DNS 係
1. hidden and 
2. N+1 DNS server 

無論你電話本身set 幾多個DNS server address
佢都會作為hidden 同第N+1 個DNS server address 嘅mechanism 去偷連

所以我個人係以陰謀論角度去睇件事

無撚有錯
根本就唔應該駁去public DNS
理得你大陸又好邊度都好

The cause of this is:

* Android needs to know if a wifi network is working, since many wifi networks are broken and connecting to them degrades the user experience.

* Normally it does that by connecting to google.com, and if the connection succeeds, assume wifi is good to go.

* Google.com is blocked in china, meaning wifi would be broken in China.

* To fix this, Samsung has replaced google.com with qq.com in china.

* Samsung also needs to add a new DNS server to resolve qq.com, in case the network doesn't provide a DNS server and androids default of Google DNS is used (which is also blocked in China). Adding it last means it won't be used unless other DNS servers are broken.

Overall, this behaviour seems like the simplest and most logical fix Samsung could put in place to enable their users to use phones in China.

They could have run their own servers (but that would also have privacy issues), or they could have removed captive portal/bad network detection, but that probably would have broken some apps and led to unhappy users.

I can't see any other real fix in this case, and I certainly don't see any malicious intent in any of their actions.

呢樣當然係啦,但難保大陸firmware一向都係咁玩法,只係唔知邊條友最近將呢段code直接copy落港版firmware度

其實最好就拎個早期冇事嘅港版同大陸版嘅firmware睇下,比較下而家中招嘅code係咪一早已經喺大陸版度

我一睇以為係你講原來係quotation
呢個解釋唔到點解要
1. Hidden and 
2. N+1

如果為咗俾洋人喺GFW 範圍內有seamless transition, 114 DNS 嘅hidden and N+1 nature 相關說明要寫喺end user agreement 入面

香港就或者其他冇集體訴訟嘅地方就唔寫或者亂寫都冇所謂

未改之前水貨機同港版情況有唔同架
水貨機係要收到中/港/澳network先有114同qq,更香港機就首先認咗你係有114同qq先,離開中/港/澳先冇114同qq

而家改咗之後係只睇部機嘅region code先睇下加唔加114,但qq就不變

SoC 係影響driver level (cpu driver, WiFi driver etc), 係再底層啲嘅layer
而家呢個衹係 *wifi*.java 寫嘅background service, code base 唔會有分別

係咪無法逃離
