1. Specifications Comparison
Design
| Feature | Samsung Galaxy A42 5G | Xiaomi Redmi A3 | Practical Impact |
|---|---|---|---|
| Dimensions | 164.4 x 75.9 x 8.6 mm | 168.3 x 76.3 x 8.3 mm | The Redmi A3 is slightly taller, while the A42 5G is a hair thicker. This is unlikely to be noticeable in everyday use. |
| Weight | 193g | 193g | Identical weight means similar feel in the hand. |
| Build | Standard | Standard | Both are standard, non-folding designs. |
| Screen Protection | Unknown | Corning Gorilla Glass 3 | Redmi A3 offers basic scratch resistance, increasing the phone's longevity. The lack of information for the A42 5G is a drawback; it's probably not protected. |
| Fingerprint Sensor | Basic | Side-mounted | Side-mounted sensors are often faster and more ergonomic than rear-mounted ones. |
Display
| Feature | Samsung Galaxy A42 5G | Xiaomi Redmi A3 | Practical Impact |
|---|---|---|---|
| Size | 6.6" | 6.71" | Slightly larger screen on the Redmi A3 offers a more immersive viewing experience for videos and games. The difference is relatively small, though. |
| Resolution | 720x1600 | 720x1650 | Both offer HD+ resolution, which can appear pixelated on larger screens. |
| PPI | 266 | 268 | Practically identical pixel density means similar sharpness. |
| Technology | AMOLED | IPS LCD | AMOLED offers superior contrast, deeper blacks, and more vibrant colors, leading to a better viewing experience. |
| Refresh Rate | 60Hz | 90Hz | The 90Hz refresh rate on the Redmi A3 makes scrolling and animations appear smoother. |
| Brightness | 0 nits | 0 nits | The brightness is strangely indicated as "0 nits" for both phones, which is not possible. This is likely a data error. Without accurate brightness data, it's impossible to compare outdoor visibility. |
Performance
| Feature | Samsung Galaxy A42 5G | Xiaomi Redmi A3 | Practical Impact |
|---|---|---|---|
| Chipset | Qualcomm Snapdragon 750 5G (8 nm) | Mediatek Helio G36 (12 nm) | The Snapdragon 750 5G is significantly more powerful, offering much faster app loading, smoother multitasking, and better gaming performance. The smaller manufacturing process (8nm vs 12nm) also contributes to better power efficiency. |
| AnTuTu Score | 392,400 | 127,000 | A stark difference. The A42 5G will handle demanding apps and games with ease, while the Redmi A3 may struggle with anything beyond basic tasks. |
| GPU | Adreno 619 | PowerVR GE8320 | The Adreno 619 is significantly better for gaming and graphically intensive tasks. |
| RAM | 4/6/8 GB | 3/4/6 GB | More RAM on the A42 5G (especially the 8GB variant) allows for smoother multitasking and keeps more apps open in the background. |
