Although Nova is still No1 in customization and functionality, Smart launcher 5 has very nice themes (icons ,wallpapers, clocks, app drawers) making it less boring (but full version is a little expensive i.m.o.)
Here is a home screen, just selected a theme, a wallpaper, and a clock from another theme.
Just got my Pixel 3a yesterday trough a very good deal when I switched to Vodafone from another provider( Black Friday deal, got it for 150€)
Anyways, transfered all my data from the old phone, and also the Nova Launcher setup which I had on the old one.
Blacked out notification bar (time, battery, etc) on home screen only
4 dock icons are from One UI Pixel icon pack, widgets ( clock weather and battery on first page and calendar on 2nd are Shadow KWGT with minor customization to the first one ( it's square not round in the original) stock Spotify widget. All the way on the left is Google Feed done with Nova Google Companion.
There is a grayish wallpaper that goes letter with Shadow KWGT as it's a Neumorphic design, but have the black wallpaper with Quadrovoglio Verde logo ( Alfa Romeo) which I did myself.
And finally letter B in the middle of the dock is a Brabus Mercedes logo that opens a folder containing most used apps.
Sorry guys for a bit longer post, any questions, feel free to ask.
In case anyone wants to put the old style nav bar on their new phone this still works
How to disable Android Pie gestures on the Google Pixel 3
1. Install any 3rd-party launcher of your choice. This is a must because otherwise, you won’t have a launcher app left once we’re done with this tutorial!
2. Set up ADB on your PC. Here’s a tutorial we previously wrote that you should you through the process.
3. Connect your Pixel 3 to your PC and open up a command prompt/terminal in the directory where you downloaded the ADB binary. Enter the following command depending on your OS:
Windows Command Prompt
Windows Power Shell
4. Now, enter the following command to uninstall the Pixel Launcher from the current user.
pm uninstall -k --user 0 com.google.android.apps.nexuslauncher
5. Now, enter this command to re-enable the stock navigation bar after reboot. This is the setting you’ll be changing by issuing the below command.
settings put secure system_navigation_keys_enabled 1
6. Reboot your Pixel 3.
7. Once you’re booted back up, you should see the original 3 button navigation bar layout and the original vertical stacked card recent apps overview.
What I did is just use Titanium Backup and freeze Pixel Launcher. After a reboot I had the old navigation back.
