4.8/5Really happy about my new phone, the delivery was fast. The box was a bit damaged but I guess it's because it reconditioned. The product is in perfect condition, it is delivered with a charger, a phone case and earphones. I recommend buying on BackMarket!

The Samsung Galaxy A31 is a mid-range smartphone launched in 2020 that delivers solid everyday performance with a focus on display quality and battery endurance. Although it is a few generations old, the Galaxy A31 remains a practical choice for users who prioritise media consumption and basic smartphone tasks.
Key features:- Release Date: March 2020
- Display: 6.4-inch Super AMOLED, 1080 x 2400 pixels resolution
- Processor: MediaTek Helio P65
- Camera: Quad-camera setup with 48MP main sensor
- Operating System: Ships with Android 10, upgradable to later versions
- Connectivity: 4G LTE support, Wi-Fi, Bluetooth 5.0
The Samsung Galaxy A31 suits users looking for a device with a vibrant display for streaming and casual photography without demanding flagship-level performance. It is ideal for students, casual users, or anyone needing a reliable smartphone for everyday activities like browsing, social media, and video playback. Compared to newer Galaxy A-series models, the A31 offers fewer processing capabilities and lacks 5G connectivity, which may be a consideration for users needing faster network speeds.
Pros & Cons:| Pros | Cons |
|---|---|
| Vibrant Super AMOLED display suitable for media consumption. | Processor performance is modest, not suited for heavy gaming or multitasking. |
| Versatile quad-camera system with a high-resolution main sensor. | No 5G support, limited to 4G LTE networks. |
| Expandable storage via microSD card. | Build materials are mostly plastic, less premium feel. |
