So after playing around for some time, here’s the only method I got to work. I may sound crazy, but it worked for me, even with the 10 extra steps.
I wanted the Flip Launcher by @sh7411usa, but it wouldn’t install on the S2720 no matter what. So I tried the Simple App Launcher, as @sams-club mentioned, but that was a no-go as well.
Left with one option, I went ahead and installed the Apps4Flip old version:
[attachment=launcher (3).apk]launcher (3).apk[/attachment] (1.6 MB) , which actually installed nicely.
Now that I had that installed, I was able to add additional apps. First, I added the original app launcher I wanted “Flip Launcher” and then went ahead and uninstalled the Apps4Flip launcher, leaving me with my desired launcher.
Here’s the coding I used to uninstall the Apps4Flip launcher on WebADB:
pm uninstall -k --user 0 com.android.cts.launcher
