另外一個蠻重要的應該是 microG Project，不過在文章裡沒提到...
The Telegram X project features apps written from scratch, with an entirely new code base and without all the legacy components that our older apps have accumulated through the years.
The goal of Telegram X is to reinvent Telegram and explore new frontiers in speed, ease of use, quality of animations and all other aspects. Today we are glad to present two new official apps – Telegram X for Android and iOS.
忘記在哪邊看到的，分析 Android APK 檔的軟體：「Droidefense: Advance Android Malware Analysis Framework」。
Droidefense (originally named atom: analysis through observation machine)* is the codename for android apps/malware analysis/reversing tool. It was built focused on security issues and tricks that malware researcher have on they every day work. For those situations on where the malware has anti-analysis routines, Droidefense attemps to bypass them in order to get to the code and 'bad boy' routine. Sometimes those techniques can be virtual machine detection, emulator detection, self certificate checking, pipes detection. tracer pid check, and so on.
Droidefense uses an innovative idea in where the code is not decompiled rather than viewed. This allow us to get the global view of the execution workflow of the code with a 100% accuracy on gathered information. With this situation, Droidefense generates a fancy html report with the results for an easy understanding.
看起來是輔助用的工具... 先記錄下來 XD
Regulators in South Korea summoned Google (GOOGL, Tech30) representatives this week to question them about a report that claimed the company was collecting data from Android devices even when location services were disabled.
U.K. data protection officials are also looking into the matter.
就如標題所寫的，Quartz 獨家刊出來的新聞，即使你關掉 Google 的定位服務，Google 還是會蒐集你的位置 (而且跟 Google 發言人確認後也證實)：「Google collects Android users’ locations even when location services are disabled」。
而且是全背景作業，在你沒有開定位服務，沒有插 SIM 卡，也沒有跑任何 app，他就會將定位資訊傳出去：
Many people realize that smartphones track their locations. But what if you actively turn off location services, haven’t used any apps, and haven’t even inserted a carrier SIM card?
從今年年初開始這樣搞的，Google 發言人只宣稱這個資料並沒有被用來整合到「network sync system」，並且會立即丟掉 (所以你還是不知道被用到什麼地方)：
“In January of this year, we began looking into using Cell ID codes as an additional signal to further improve the speed and performance of message delivery,” the Google spokesperson said in an email. “However, we never incorporated Cell ID into our network sync system, so that data was immediately discarded, and we updated it to no longer request Cell ID.”
這句話的意思其實代表著是丟掉 raw data，改以統計的方式轉移存到其他系統。
If they were “never used or stored”, why did they start collecting them in the first place? This is like a kid caught with their hand in the cookie jar saying they weren’t going to eat any cookies. Sure.
這次的事情是 microG 的人 fork 了 LineageOS 專案，因為 LineageOS 專案拒絕 microG 的 signature spoofing patch：
Why do we need a custom build of LineageOS to have microG? Can't I install microG on the official LineageOS?
MicroG requires a patch called "signature spoofing", which allows the microG's apps to spoof themselves as Google Apps. LineageOS' developers refused (multiple times) to include the patch, forcing us to fork their project.
Wait, on their FAQ page I see that they don't want to include the patch for security reasons. Is this ROM unsafe?
No. LineageOS' developers hide behind the "security reasons" shield, but in reality they don't care enough about the freedom of their users to risk to upset Google by giving them an alternative to the Play Services.
The signature spoofing could be an unsafe feature only if the user blindly gives any permission to any app, as this permission can't be obtained automatically by the apps.
Moreover, to further strengthen the security of our ROM, we modified the signature spoofing permission so that only system privileged apps can obtain it, and no security threat is posed to our users.
於是就 fork 了新的專案... 就觀察看看吧。
It appears that “DNS over TLS” support is being added to Android, according to several commits added to the Android Open Source Project (AOSP). The addition in the Android repository shows that a new setting will be added under Developer Options allowing users to turn on or off DNS over TLS. Presumably, if such an option is being added to Developer Options, then that means it is in testing and may arrive in a future version of Android such as version 8.1.
這邊用的應該是 RFC 7858 的「Specification for DNS over Transport Layer Security (TLS)」，已經是 Standards Track 了。預設使用 TCP port 853：
By default, a DNS client desiring privacy from DNS over TLS from a particular server MUST establish a TCP connection to port 853 on the server, unless it has mutual agreement with its server to use a port other than port 853 for DNS over TLS.
而且建議如果另外定義的話，不要用 port 53：
This recommendation against use of port 53 for DNS over TLS is to avoid complication in selecting use or non-use of TLS and to reduce risk of downgrade attacks.
另外也說明了在 port 853 上禁用明文傳輸：
DNS clients and servers MUST NOT use port 853 to transport cleartext DNS messages.
不過即使將 DNS query 保護起來，TLS 本身還是會透漏 hostname 的部份 (因為 SNI 的關係)，所以就 privacy 面向考量的話，沒有實質的意義... 主要還是考慮被竄改的問題？但如果是這樣的話，目前 TLS 連線本身就已經有這樣的保護了？暫時沒想到可以解什麼實際的問題...
微軟宣佈在 iOS、Android 以及微軟自家的系統上都推出 Microsoft Edge：「Announcing Microsoft Edge for iOS and Android, Microsoft Launcher」，另外也很「貼心」的整理了一篇不同平台上的差異 (尤其是 iOS 與 Android)：「Microsoft Edge for iOS and Android: What developers need to know」。
不過 Twitter 上微軟自家人 Kyle Pflug 講的比較簡單：
Tl;dr: Microsoft Edge is built on Chromium on Android, WKWebView on iOS, EdgeHTML on Windows. UA string has "EdgiOS" or "EdgA" tokens. https://t.co/dauZNETTdJ

把重點講的超清楚，然後順建讓人有種 WTF 的感覺 XDDD (等於是一次推出三個不同行為的 browser 啊！)
2013 的時候提過「加州的手機防竊提案...」，後來在 2015 年生效：
In a press release sent to reporters on Thursday, George Gascón said that since the law went into effect on July 1, 2015[,]
Such a kill switch has become standard in all iPhones ("Activation Lock") and Android phones ("Device Protection") since 2015.
而執行到現在已經兩年了，手機的失竊率下降不少：「San Francisco DA: Anti-theft law results in huge drop in stolen phones」。
[S]martphone-related robberies have fallen 22 percent from 2015 to 2016. When measured from the peak in 2013, "overall robberies involving smartphones have declined an astonishing 50 percent."
