The value in nanometers represents half the distance between elements that make up the CPU. The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening. The 48MP mode lets you extract some more fine detail in well-lit scenes. You'd need to be willing to live with the lower contrast and loss of saturation plus noise gets more prominent. But yes, there's some finer detail in the 48MP shots. Typical value tested under third-party laboratory condition. Typical value is the estimated average value considering the deviation in battery capacity among the battery samples tested under IEC 61960 standard. Rated (minimum) capacity is 4,370 mAh. Actual battery life may vary depending on network environment, usage patterns and other factors.

Rear cameras: Wide (main): 48 MP, f/2.0, 26mm, 1/2.0", 0.8µm, PDAF; Ultra wide angle: 12 MP, f/2.2, 123˚; Macro: 5 MP, f/2.4; Depth: 5 MP, f/2.2; LED flash, panorama, HDR. Usable memory size is less than the total memory size due to storage of the operating system and software required to operate the phones' features. Actual usable memory size will also vary depending on the mobile phone operator and may change after software upgrades are performed. There's nothing new to report here, either, as the single bottom-firing speaker on the Galaxy A51 5G is as unimpressive as it was on the LTE model. The audio is flat and it'll leave you wishing for more bass. The speaker clearly wasn't on Samsung's list of priorities for the Galaxy A51. This seems like a missed opportunity because Samsung could have improved it on the 5G variant but it chose not to. A select few people will appreciate it, but it's worth mentioning that a double press on the power button launches the camera app and another double press will switch between front and rear too. Couple that with the option to use the volume keys for shutter release and you have a camera app that you can start and operate almost entirely without touch input. Image qualityThe ultra-wide cam's output is a step up from the A51's too. While not spectacular, the images do contain some detail, particularly in well-lit areas of the frame, though they are predictably noisy. Colors rendition is good - there's no substantial desaturation, and dynamic range is decent for an ultra-wide in the dark. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. UMTS Another improvement is the Pro mode. Typically, Samsung midrangers get a very basic set of photographic control with just ISO, exposure compensation, and white balance, and that was the case on the A51. The A51 5G, on the other hand, gets the full-fledged Pro mode that flagships have. The ultra-wide cam continues the good impression. It captures good detail (despite the softish corners) with no noise to speak of. The ultra-wide shots also maintain a wide dynamic range. Colors rendition is a good match for the main cam's lively output as well. You can select ISO (50-3200), push shutter speed around (1/6000s-10s), focus manually (with peaking), and select the white balance (by light temperature, with icons next to the number corresponding to a common light source). Metering mode and AF area options are available too, as well as a set of picture controls for contrast, saturation, and whatnot. As usual, there's no live histogram.

On the Galaxy A51 5G, video stabilization is available in all modes, an upgrade from the A51's 1080p-only EIS. Much like on the older model, we did find the A51 5G's main cam to hunt for focus when shooting while walking, which does ruin the perception of stability. Keeping it pointed at a subject will result in nicely stable videos. The ultra wide, being fixed focus, doesn't suffer from that and you can easily walk and shoot with it. The front-facing camera has remained the same as well - a 32MP Tetracell sensor with an f/2.2 lens in front, no autofocus. The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute. Versions: SM-A516B/DS (International), SM-A516U (USA), SM-A516F/DSN, SM-A516N (South Korea) NetworkThe handset runs Android 10 out of the box with the latest iteration of Samsung's One UI custom skin. It brings several new features such as Bixby Routines, App Pairs and Edge screen. Bixby Voice is present as well. Focus mode, improved parental controls and Google's navigation gestures are part and parcel of Android 10. Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. Footage from the ultra-wide cam does have a very overprocessed look if you're to examine it from up close though it is quite detailed nonetheless. Dynamic range is once again excellent, while colors are a bit more saturated than what you'd get from the main cam. If you're willing to pay the premium for 5G this early in its adoption, even on a midranger like the A51 5G, chances are you'd probably enjoy a more upmarket build and Samsung has obliged. It's replaced the plastic midframe with an aluminum one. This remodeling, complete with the battery capacity bump and the extra antennas all means that the A51 5G is now 15g heavier - a not insignificant increase that robs it of all claims for lightness.
