OneUI 7.0: icon array in landscape view is tiny, and has rearranged icons

[dpbsmith]

Samsung Galaxy Tab S9 FE, SM-X510. Android 15, OneUI 7.0.

I just got the OneUI 7.0 update. One (of many) issues is that in landscape orientation, the entire icon grid array shrinks down to occupy only a tiny portion of the screen. It occupies roughly half the width and roughly half the height. It is actually smaller than the icon grid when displayed in portrait orientation.

I can't find anything relevant in the Settings app. The Home Screen App Size setting is close to ineffective, making only a very small change in the app size, in either orientation. The only choice of grid sizes are 8x6 and 10x6, and 10x6 actually makes things worse. 

In addition, the layout I was using before the update as preserved in portrait orientation, but a number of icons were moved in somewhat unpredictable ways in landscape orientation. The layout now actually changes when I switch from portrait to landscape orientation. It's going to take a bit of annoying work to put them back where I want them.

I have the same thing and I’m F’n p1ssed.  Samsung better fix this BS.

Got work I need to be doing, not screwing around with this BS.

The app size slider doesn’t do anything either.  And no, it’s not zoom either.  I want my right screen size back.

Getting somewhere now, but the “fix” sucks.  You have to remake all your f’n home screens.  I’m not BS’n you.  You have to delete and redo widgets.  Gueee what?  Transparency no longer is an option with many widgets anymore.  It used to look awesome, now it looks like sht.  F’ you Samsung.  I just updated my iPad to iOS 26 also and it’s gorgeous.

Have you ever used the Home Up module in the Good Lock app? With it, you can easily customize your homepage to your satisfaction.

Home Up helps a little but doesn't completely allow full screen (16:9), the largest is 6x6 which does NOT completely fill the home screen.

Samsung, shame on you!

Thanks for the suggestion, but after too many bad experiences, I no longer use applications intended to modify or customize UI. They're just too fragile. That's a decision I came to over a decade ago!

(If the core OS has intentional, engineered, documented API that's intended to allow third party developers to create customizations, it would be OK).

For what it's worth, Good Lock is not third-party, it's a Samsung app.

According to the Samsung Store, it's not from Samsung. It's from a third party developer named "Good Lock Labs."
