User Available Memory : User memory is less than the total memory due to storage of the operating system and software used to operate the device features. Actual user memory will vary depending on the operator and may change after software upgrades are performed. Like most phones at the price, the Samsung Galaxy A51 offers no official water resistance. But it does have a 3.5mm headphone port, which is handy if you are yet to make the jump to Bluetooth headphones. The Samsung Galaxy A51 offers some of the design traits of Samsung's higher-end phones. But there are a few giveaways that it is not part of the pricey Galaxy S series. SM-A515F, SM-A515F/DSN, SM-A515F/DS, SM-A515F/DST, SM-A515F/DSM, SM-A515F/N, SM-A515U, SM-A515U1, SM-A515W, SM-A515X, SM-S515DL The Samsung Galaxy A51's 5MP macro camera will not see you win a Wildlife Photographer of the Year award, but it is fun to play around with. You can get extremely close to your subject, and shoot objects the main camera won't even focus on. Its main issue, other than only passable image quality, is blurring. A little handshake movement will ruin your photos unless the light level is good.

Display Size: Measured diagonally, the screen size is 6.5" in the full rectangle and 6.3" with accounting for the rounded corners. Actual viewable area is less due to the rounded corners and the camera cutout. Samsung’s brand has never seemed stronger among Androids too, now that we’re more likely to recommend an Oppo phone than one made by Sony, HTC, or Huawei.

Summary

One important part of the A51 is below average at the price, though: performance. The Galaxy A51 makes Android feel a little slow, more so than the usual app load discrepancy between a good affordable phone and a top-end one. The Samsung Galaxy A51’s draws are similar to those of other mid-price Samsungs. Its OLED screen is colorful, contrast is ultra-high, and Samsung’s software looks good. It's not hard to spot the filler: those two 5MP cameras. But this case is much less egregious than, for example, what Oppo has tried recently. The Oppo A9 2020 has a couple of intensely useless 2MP cameras. While those crashes likely won’t be an issue for long, the general sluggishness may be. Camera performance issues are intermittent rather than constant, but we did notice them regularly while out shooting.

It has an in-screen fingerprint scanner too, another attempt to make the Samsung Galaxy A51 seem like a high-end phone. However, this is not a great scanner. It is slower than most and will fail to recognize fingers if they are even slightly wet, or if you are not very careful about the position of your thumb. The network capacity and data transfer speed may be reduced while dual SIM cards are used at the same time. A Splash of Color and Samsung Premium Care Come to Galaxy A51".

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 are a few little issues. You don't get a reliable view of the shot you take in the camera app. What you see is before the processing has been applied, with no indication of how much better HDR will make the picture look. The good news? That means the final image will actually be a lot better.

The Samsung Galaxy A51 SM-A515F is an Android Smartphone. It has 6.5 inches, FHD+ 1080 x 2400 pixels screen resolution. And it is powered by Exynos 9611 Octa-Core CPU, and Mali-G72 MP3 GPU. It runs Android 10. Battery time is based on our own laboratory measurements, and may vary depending on factors such as device settings, usage patterns and operating conditions. There's no zoom, which is the classic sign of a multi-camera setup where extra lenses are used to bulk up the numbers. We can't blame Samsung completely for this, as it is not easy to fit a good zoom camera into a reasonably priced phone.

🔌 Connectivity

With most titles you get an experience fairly close to that of a more expensive phone, which is a sweet consolation after the general performance hitches. The Samsung Galaxy A51's screen also makes games look great. But there’s a lot of Snapdragon-powered competition at the price, and they seem to offer more consistent results.
