Nova allows you to tweak almost every aspect of the interface. You can adjust the number of rows and columns on the home screen and app drawer independently. The "Sub-grid positioning" feature allows icons to sit halfway between grid lines, giving you precise control over layout density.
Before diving into the "Prime" aspect, let’s establish what Nova Launcher 5.5.4 is. Released in late 2017/early 2018, version 5.5.4 was a milestone build. It represented the mature peak of the "Nova 5" series, which introduced major features like Pixel-style search bar integration, dynamic app shortcuts (Android 7.1+) , and improved adaptive icons.
Unlike the bloated launchers of today, version 5.5.4 was lean. It was built on the foundation of Android Nougat and Oreo but remains backward compatible with devices running Android 4.0.3 (Ice Cream Sandwich) through to Android 9 Pie. This makes it a perfect choice for older hardware or users who hate the direction modern launchers have taken with cloud features and analytics.
You might wonder why someone would seek out an older version like 5.5.4 when version 8.0 is available.
This version supports icon packs perfectly. You can apply a pack globally or customize individual icons. The Prime version allows you to set different icon shapes (like squircles or rounded squares) even if your phone’s OEM skin doesn't support it natively.
