A smartphone with a pre -installed Android 9 Pie has begun to appear.Even the existing Android smartphone has begun to upgrade to the OS (reference article).
When upgrading the OS version, new functions and specification changes are included.Android 9 is no exception (reference article).However, there are some changes that the terminal manufacturers do not try to adopt much.
Android 9世代のGoogleスマートフォン「Pixel 3」In Android, the system key used to operate apps such as "return", "home" and "task history (app history)" is called "navigation key".Android 3.0 (Android 4 on your smartphone.0) In the following OS, it is recommended that these keys are displayed on the screen as "navigation bar".
Android 3.0（4.0）以降では「ナビゲーションバー」として画面内設置が推奨されているナビゲーションキー。写真のように一般的には「戻る」「ホーム」「タスク」の3つが配されるが、メーカーによってはカスタマイズで他の機能も持たせている場合があるIn Android 9, this navigation bar has been renewed.The main changes are as follows.
In particular, the integration of home keys and task keys is a major change.Operations equivalent to the conventional task key have been replaced with "home key upper swipe".
The Google smartphone "Pixel 3" and "Pixel 3 XL", which pre -install the OS, adopt this new navigation bar.The operation system has been renewed.
Android 9の新しいナビゲーションバー。タスクキーがホームキーに統合され、不要な時は戻るキーも表示されない従来のタスクキーに相当する機能は、ホームキーを上方にスワイプすると出てくる自動画面がオフの時に、横画面表示にも対応するアプリを起動して端末を横に倒すと、横画面表示で固定するためのキー（アイコン）が出るようになったThis new navigation bar will be adopted on third -party terminals that pre -install Android 9, and it doesn't seem surprisingly.
First, Sony Mobile Communications "Xperia XZ3", which quickly announced the pre -installation of the OS, is equipped with an old navigation bar.It does not support the new navigation bar.

On the other hand, Sharp's "AQUOS ZERO" and "AQUOS R2 COMPACT" are used as standard new navigation bars, but if you change the settings, you can use the conventional navigation bar (reference article).For the "Essential Phone", which was upgraded quickly, the new and new navigation bars can be switched.
AQUOS zero（写真）やAQUOS R2 compactは、新旧どちらのナビゲーションバーも使えるようになっているIn this way, even a smartphone that pre -install Android 9 is determined whether to use a new navigation bar.Why is it?
As mentioned earlier, the operation method of the new navigation bar has been renewed.When I asked multiple acquaintances who usually use Android to use Pixel 3 / Pixel 3 XL, almost everyone was confused by the operation.When the operation system changes, there are definitely users who cannot operate well.
Manufacturers who did not adopt a new navigation bar may not have dared to adopt the new navigation bar to eliminate the confusion of the user.
Some say, "You can switch like Sharp or Essential Phone."I can't say.Although it is a reverse pattern, it may not be possible to switch to the old navigation bar in Pixel 3 / Pixel 3 XL, which may be from the perspective of avoiding confusion about "careless switching".
Pixel 3の画面設定では、旧ナビゲーションバーへの切り替えができないAnother reason for not adopting it is the "affinity" between the home app developed in -house and the new navigation bar.Pixel 3 / Pixel 3 XL's original home application "Pixel Launcer" has a high affinity with the new navigation bar, and can display the Google search window and frequently used apps in the task display.
As a result of examining the affinity of such a new operation system and the affinity of the original home app, it is thought that the early Android 9 terminal has forgotten the new navigation bar.
If you get a certain "answer" in the compatibility of your own home app, there is a possibility that new models and software updates will be available for new navigation bars.

新ナビゲーションバーを採用しないMate 20 Proだが、新しい画面固定機能は採用されたAnyway, it is natural that a certain rejection will occur in the new operation system.It seems that it will take some time for a new navigation bar of Android 9 to "penetrate" between the terminal manufacturer and the user.
