上周三下午，谷歌的最新移動操作系統(tǒng)Android 10正式發(fā)布。Android 10迎來了不少重大升級，小改動更是不計其數(shù)。

考慮到全球有四分之三以上的智能手機用戶最終都會用上Android 10，現(xiàn)在就讓我們看看，Android 10有哪些我們應(yīng)該了解的重大改進。

我什么時候能升級到Android 10？

目前，谷歌自家的Pixel系列旗艦機型，以及部分其他品牌的手機已經(jīng)開始推送Android 10了。如果你的Pixel手機沒有收到自動推送，你可以在升統(tǒng)菜單里點擊“系統(tǒng)升級”（也就是那個齒輪圖標），手動下載Android 10更新包（大約1GB）。

據(jù)報道，從昨天起，Android創(chuàng)始人安迪·魯賓的手機品牌Essential Phone，以及小米的紅米K20也開始推送Android 10的更新包了。

其他型號手機的機主可能還得再等上一陣子，畢竟大多數(shù)手機廠商都會花時間對新系統(tǒng)針對自家手機進行優(yōu)化，因此等上幾周甚至幾個月都是有可能的。比如三星Galaxy系列的用戶，說不定2020年前都沒法用上Android 10。

Android 10升級了哪些功能？

Android 10有幾十項升級，既包括菜單設(shè)計和后臺調(diào)整這種消費者不太注意的到的小變化，也有人機交互方式上的大變化。Android 10的全部調(diào)整可以在版本說明里找到，下面只說幾點最令人期待的變化：

黑暗模式

打開“黑暗模式”，大多數(shù)應(yīng)用和菜單就會變成黑色背景，而文字則變成白色。黑暗模式可以延長電池壽命，而且一些用戶使用起來也會覺得更舒適。在以前的幾個Android版本中，用戶也可以將菜單和屏幕設(shè)置成黑色主題，但對第三方APP是沒有影響的。而Android 10則真正實現(xiàn)了覆蓋全系統(tǒng)的黑暗模式。

智能回復(fù)

以前的幾個Android已經(jīng)可以在短信息等應(yīng)用里使用系統(tǒng)自成生成的快捷回復(fù)。不過有了Android 10的智能回復(fù)功能，系統(tǒng)會自動結(jié)合語境給出一些推薦操作。比如有人用短信發(fā)來一個地址時，系統(tǒng)會自動建議打開地圖應(yīng)用。

手勢控制

如果你下載了Android 10，你會發(fā)現(xiàn)，屏幕下方出現(xiàn)了新的一欄，你可以在這里滑動選擇最近使用過的應(yīng)用，或者回到主屏幕。不過這跟谷歌據(jù)說將在Pixel 4上使用的“隔空手勢操作”并非一回事。

更好的隱私控制

這可能是Android 10變化最大的地方了。Android 10把所有的應(yīng)用權(quán)限放在了一個地方。這樣一來，你就可以很容易地決定哪些應(yīng)用可以使用你的地理位置信息、日歷信息或者獲取你的個人數(shù)據(jù)。

考慮到隱私問題最近受關(guān)注程度之高，Android 10的這一功能來得正及時。

全新emoji表情

人人都喜歡emoji表情，畢竟“一圖勝千言”。今年早些時候，谷歌便宣稱Android 10將攜帶65個全新的emoji表情，包括一個聽診器，一只水獺，以及各種性別和種族混搭的情侶表情等等。

專注模式

Android 10的“專注模式”允許用戶在一定時間內(nèi)停止選定應(yīng)用推送通知消息。如果你悲哀地發(fā)現(xiàn)，自己已經(jīng)患上了“網(wǎng)癮綜合癥”，該模式據(jù)說還會提醒你現(xiàn)在有更重要的事情去做。

除了“專注模式”，Android 10還提供了其他一些“數(shù)字健康工具”，比如“應(yīng)用定時器”功能可以幫你控制每天耗費在某個應(yīng)用上的時間。

家庭控制

現(xiàn)在的家長越來越關(guān)心孩子的網(wǎng)癮問題。Android 10全新推出的“家庭鏈接”功能，使家長可以控制孩子使用的設(shè)備的亮屏時間，監(jiān)控孩子們使用了哪些應(yīng)用程序，甚至可以查看孩子手機的地理位置。

除了以上功能，Android 10還有不少其他的升級，比如可以更快地推送安全補丁，可以支持更多的照片文件類型等等。此外，Android 10還自帶了一個Live Caption實時字幕工具，可以將任何音頻文件轉(zhuǎn)換成字幕。要想了解更多，可以點擊此處查看Android 10的所有最新功能。（財富中文網(wǎng)）

Google’s newest mobile operating system, Android 10, was released Wednesday afternoon. There are dozens of small tweaks in the update, and a quite a few major ones.

Here are the most important things to know about the operating system heading (eventually) to more than three quarters of the world’s smartphone users.

When and how can I update my phone to Android 10?

Android 10 is now available for Google’s own Pixel flagship phones, as well as on phones from a few other companies. If your Pixel doesn’t receive an update prompt automatically, run System Update under the System menu (the gear icon), to download Android 10's roughly 1GB update file.

The Essential Phone (a project of Android co-creator Andy Rubin) and the non-U.S. Xiaomi Redmi K20 also reportedly started receiving the update as early as yesterday.

Owners of other phone models will probably have to wait to download the Android 10 update, since most manufacturers take some time to prepare new Android releases for their devices. That often takes weeks or even months. Samsung Galaxy users, for instance, might not get Android 10 until 2020.

What’s in the Android 10 update?

There are dozens of changes in Android 10, from small tweaks to menu designs and back-end changes that users are unlikely to notice, to large changes to the way you’ll interact with your phone. The full details can be found in the Android 10 release notes, but these features are the most anticipated changes:

Dark Mode

Turn this on, and your phone will display white text against a black background, across most apps and menus. Dark mode improves battery life, and is more comfortable for some users. In previous Android versions, the operating system’s own menus and screens could be set to a dark theme, but there was no option for a system-wide dark mode that also affected apps. That will change with the Android 10's release.

Smart Reply

Previous flavors of Android had already suggested some automatically-generated replies to messages such as texts. But with Android 10's Smart Reply feature, the Google's operating system will also suggest contextual actions, like opening Maps when someone texts you an address.

Improved gesture controls

A new bar at the bottom of the screen on phones that have downloaded Android 10 will allow users to ‘swipe’ between recently-used apps, or to return to the home screen. But this is not to be confused with hands-free swiping, reportedly coming to Google’s Pixel 4.

Better privacy controls

In what might be the single biggest change to Google's mobile operating system, Android 10 places all app permissions in one place, making it immensely easier to control which applications can use your location data, read your calendar, or otherwise access data about you.

Given recent heightened attention to tech and privacy, this Android 10 feature is a badly-needed one.

New emoji

Everyone loves emoji; they might make our communication more efficient and precise. Google earlier this year announced 65 new emoji are coming with Android 10, including a stethoscope, an array of gender- and racially-inclusive couples, and, well, an otter.

Focus Mode

Android 10’s new Focus Mode will let users stop notifications for selected apps over a set amount of time. And if you do find yourself compulsively opening apps as a time-wasting distraction, the setting will even reportedly remind you that you’ve got better things to do.

Focus Mode arrives in Android 10 along with a few other ‘digital wellbeing’ tools, like ‘a(chǎn)pp timers’ that help you control the amount of time you to spend in an app each day.

Family Controls

Parents are increasingly concerned with keeping kids from overindulging in screen time. Android 10’s new “Family Link” allows parents to use their own phone to control screen time on their kids’ devices, monitor what apps are being used, and even see the location of their children’s phones.

In addition to the above features, Android 10's other updates include faster delivery of security fixes, support for more photo file types, and a Live Caption tool that lets users translate any audio into text. For more, check out Google’s own detailed rundown of all the new features in Android 10.
