- Much Better Display: The higher resolution (1080p vs 720p) and pixel density of the Realme 9i's display makes a huge difference in clarity and sharpness, leading to a much better overall viewing experience. The 90Hz refresh rate makes it noticeably smoother.
- Better Camera: The Realme 9i has a much better camera overall, not just the main camera which is 50MP vs 13MP in the Galaxy A02, but also in the selfie camera (16MP vs 5MP) and features (PDAF, Triple camera).
- Faster Charging: The 33W fast charging on the Realme 9i is a significant advantage over the slow 7.5W charging of the Samsung A02. This means less time waiting for your phone to charge.
- Modern Features: The Realme 9i offers modern features like the newer Android version, Bluetooth 5.0, side-mounted fingerprint sensor, Hi-Res Audio, Stereo speakers and faster Wi-Fi, which are absent in the Galaxy A02.
- Value for Money: While the Samsung A02 might be slightly cheaper, the Realme 9i offers much better value for the money given the significantly better performance, camera, and display.
