I am helping an older relative transfer data to a replacement phone. Both the old and new phones are Samsung Galaxy J3 Eclipses. Here's a screenshot I took of the original phone home screen. Note the top row appears to be a width of 4 grid slots, and the next two rows have 3 apps each:
This is desirable for both the large icons and to avoid information overload. It's obviously possible, but looking through the settings I only see 4x4, 4x5 and 5x5 settings for the grid layout. How can I replicate the previous layout?
