Summary
- The Samsung Galaxy A30 features a larger 6.4-inch Super AMOLED display with a resolution of 1080 x 2340 pixels, while the A40 has a smaller 5.9-inch display with the same resolution but a higher pixel density of approximately 437 ppi.
- Both devices are powered by the Exynos 7904 chipset, but the A40 has slightly higher CPU clock speeds and more RAM options, which may enhance performance.
- Camera specifications are similar, with both having a 16 MP main sensor and a 5 MP ultrawide lens, but the A40 offers a higher resolution 25 MP front camera.
- The A30 has a larger 4000 mAh battery compared to the A40's 3100 mAh, providing potentially longer usage time.
- Both phones run Android 9.0, upgradeable to Android 11, and have similar build quality with glass fronts and plastic backs, but the A40 includes NFC connectivity, which the A30 lacks.
