Fast forward to 2025 (or beyond), and the story changes. Official software support from Realme ended years ago at Android 10 (or Android 11 for some regions). Apps are getting heavier, security patches are dusty, and ColorOS has become a bloated memory hog.
The Snapdragon 720G is still a capable chip, but ColorOS’s background processes choke it. Lineage OS has zero bloat. No HeyRealme, no Hot Apps, no duplicate Gallery/Photos apps. The UI feels snappier than the day you unboxed the phone.

While Realme left you on Android 11, Lineage OS 21 brings you up to Android 14. You get Material You theming, better privacy controls (camera/mic indicators), and improved battery optimization.
The unofficial (and sometimes official) builds of Lineage OS for the Realme 3 Pro (codenamed RMX1851 ) are turning this aging warrior into a lean, mean, AOSP machine. If your Realme 3 Pro feels like it’s wading through treacle, stock Android is the cure. Here is what you gain: lineage os for realme 3 pro
If you have a dusty Realme 3 Pro sitting in a drawer, pull it out. Flash Lineage OS. You’ll be shocked at how relevant a 4-year-old phone can feel.
You rely on banking apps without wanting to mess with Magisk (Root hide), or if VoLTE is critical in your area and you aren't willing to troubleshoot. Final Thought The Realme 3 Pro is a classic example of great hardware ruined by mediocre long-term software support. Lineage OS doesn't just "fix" the phone; it redefines it. Fast forward to 2025 (or beyond), and the story changes
Remember the Realme 3 Pro? Back in 2019, it was the "speed king" of the mid-range segment. Powered by the Snapdragon 720G, it offered VOOC 3.0 charging and a 90Hz-ish software experience (via the "Sporty" mode) for a killer price.
