Uninterrupted viewing on the superb 6.5-inch display and professional-level photography on the quad-camera make this a perfect choice for your next phone.
Many phones in this price bracket opt for a cheaper LCD screen, but the Samsung Galaxy A51 has a much better 6.5-inch Super AMOLED display. The screen has a resolution of 1080x 2400 and includes features to make sure you get a great view wherever you are.
With vivid screen mode, the contrast increases, so you get clear and crisp details in a dark room. The maximum brightness of the display is excellent when using outside. The screen automatically detects the light in your surroundings and adjusts the brightness and contrast to suit. You don’t need to do anything; you get the best view instantly.
The large screen size makes it great for watching your favourite shows or browsing through your photos. The display is certified for HD Netflix, so the latest shows stream in excellent quality.
The Samsung Galaxy A51 has a camera that you will love. There is a quad-camera with a 48MP camera and secondary lenses that help to elevate your photos to a professional level. You get a 12MP ultra-wide camera and a 5MP depth, and macro lens. With a 48MP camera lens, your photos have a lot of detail so you can take a shot of a big area and zoom into small sections without losing detail.
The Samsung Galaxy A51 has a 5MP macro lens that can capture the tiny details other camera lenses can't. If you love taking sunset photos or getting a shot of vast landscapes, the ultra-wide camera is for you. It can capture a much more full shot than other cameras, so you see more of the frame. The last of the four lenses is a depth sensor, which lets you blur backgrounds, so your subject is the main focus. Video records at 4K resolution, and with Night Mode, you get great photos even if the room is dark.
Samsung has also given you an excellent camera on the front with a 32MP selfie camera. AI image processing will automatically enhance the image, so you look your best. With beauty modes, you can adjust things like skin tone, eyes, and smooth out the skin before sharing the photo.
The Samsung Galaxy A51 is packing a 4,000mAh battery, which is a good capacity for a phone of this price. Intelligent power management and system tools help you to keep the phone performance and battery in tip-top condition.
There is no wireless charging, but you get a 15W charging cable included. With Fast Charge, you can quickly boost the battery power and enjoy up to 20 hours of video playback from each charge.
The Samsung Galaxy A51 is an Android 10 smartphone with the Samsung One UI software onboard. The One UI makes the phone easy to use, and it's quick when looking for an app or setting. You can sort apps into folders to keep everything organised.
The phone uses the Exynos 9611 processor to handle multiple apps smoothly. If you love playing games on your phone, the Samsung Galaxy A51 has the performance you need. A powerful GPU and 4GB RAM make sure you get lag-free gaming no matter how demanding the game. The speaker sits at the bottom of the phone, so game sounds and music are good quality on this phone.
A 128GB memory delivers lots of storage right out of the box. The look of the Samsung Galaxy A51 makes it look like a high-end smartphone. The sleek glass front protects the display, and the selfie camera sits in a small punch hole in the middle of the screen. The phone's back has a unique reflective design that shimmers when catching the light, making this phone stand out from the crowd.
