Why is imposible to fit a background wallpaper on my tablet

Why is imposible to fit a background wallpaper on my tablet SM-T580 after upgrading to Android 7.0. Utill I had the upgrade everything was perfectly fine. When I was chosing a wallpaper even smaller or larger ratio I had the build in option from "set as wallpaper" that was showing me how the wallpaper will look like in portrait and lanscape mode and it was fitting nice.
Now is just zooming the any picture I try when I'm rotating the screen, the set as wallpaper because that feature dissappeared after upgrade, the wallpaper will look nice on the screen only in the mode it was set as a wallpaper . I tried apps but still the same problem. Regards

Welcome to the forums. Have you tried a different launcher, like Nova? It may be an issue with the stock one.

Yes I tried but nothing changes.

Short of a reset, I am not sure what to suggest. Even a reset may not help if it is an error in the ROM.

Welcome to the forums. Is this happening even with the wallpapers that came preinstalled in your device or only with images that you downloaded? Which way are you trying to set the wallpaper, from the settings, from the gallery app, from any third party app or from the launcher after a long press on your home screen?

Tried different luncher, I tried everything. Before the android upgrade there was no problem. I found a YouTube video that shows what I'm talking about Watch "How to change a portrait wallpaper to landscape" on YouTube
https://youtu.be/o1zMppB-LOA I don't have any more those lines for landscape and portrait that can crop the picture before press done. So every wallpaper even the default ones from the sistem look like crap when you rotate the tablet. I only can have one side that looks good depends if it was set on the landscape or portrait.

The wallpapper is just zooming in when I rotate the tablet
