The Android 9 Pie update brought many visual changes, some of which are a bit reminiscent of iOS. There are the new gesture controls that are fine, but there are also things like a left-aligned clock and the fact that the current Apps menu now scrolls horizontally rather than vertically. Fortunately, Samsung has offered us a way to restore the classic Android style.
Horizontal, up-to-date apps look nice, but are less functional. If this menu was vertical, you could clearly see the last five or more apps you used, so you can easily go back to one. However, since the phone is larger than it is wide, this means that scrolling this menu horizontally means you can only see one or two of your most recent apps at the same time. However, with the help of one of Samsung's best apps, you can now bring things back to their original state.
: Install Good Lock 2019
First, you should know that this only works if you have a Samsung Galaxy device running the Android 9 Pie Update (One UI). This method does not work on other devices.
To get started, go to the Galaxy Store (this app is in your app drawer), search for "Good Lock" and install it. This is Samsung's own app, and it's very useful to change all the little things on your Galaxy.
If you have it installed, check your app's drawer. Make sure you have the version "Good Lock 2019" instead of "Good Lock 2018". At the time of writing, Good Lock 2019 was not yet available in all regions and devices. It is noteworthy that the Galaxy S10 still receives the 2018 version of Good Lock, which does not work with this mod. All you can do is wait and see if that's the case, but Samsung should update Good Lock for S10 users in the coming weeks.
If you're not using S10, you still get the 2018 version of Good Lock, the update may not yet be available in your region. You can try loading the 2019 version via the link below, but some users have reported that this does not work, so you probably only have to wait like the S10 users.
With the 2019 version of Good Lock, the rest is pretty straightforward. Open Good Lock in your app drawer and tap the "Task Changer" placeholder. You will be directed to the installation page of the Task Changer plug-in. Then tap "Install".
Now open Good Lock and tap on "Task Changer" again – this time the interface of the plugin should open. Tap the toggle next to Unused to turn it on and choose Layout Type. Select "List" from the command prompt and you're done!
Now your last opened Apps menu will be vertically aligned again. There is even a smooth animation when the tiles are faded in and out, and a bounce effect when you scroll. You can swipe vertically to see more apps (though on most Galaxy phones you can see five apps at once), and you can swipe left or right to remove an app from the list.
