Everybody knows that the Samsung Galaxy S21 Ultra had been launch on 14th jan 2021. Here i would tell you some feature of this mobile.

The Samsung Galaxy S21 Ultra 5G is the most premium smartphone yet, with a strong focus on cameras. Just like the Galaxy S20 Ultra , this new model boasts of 100X “space zoom” and 8K video recording, but with an improved shooting experience and even better image quality.

Know we talked about the design and main specifications of the Galaxy S21 Ultra 5G in our recent first impressions article, so for this review, we'll dive straight into the cameras and system performance first. If you are serious about photography or capturing video, then you should be interested in the Galaxy S21 Ultra.

The Samsung Galaxy S21 Ultra 5G starts at Rs. 1,05,999 for 12GB of RAM and 256GB of storage, and there's a second option priced at Rs. 1,16,999 which has 16GB of RAM and 512GB of storage.

Samsung Galaxy S21 Ultra 5G cameras

While the camera capabilities of the Galaxy S21 Ultra 5G is very good. There's a new-generation 108-megapixel primary camera which does nona-pixel binning, combining information from nine pixels into one, for more detailed 12-megapixel photos.

There's a 12-megapixel ultra-wide-angle camera and two telephoto cameras. The latter both have 10-megapixel sensors, but with different types of optical zoom lenses. One has a 3X optical zoom, while the other is capable of 10X, with a periscope-style lens. There's no mention of hybrid zoom this time, however there's still some AI processing being applied at higher magnification levels.

Samsung continues to Space Zoom, which on the Galaxy S21 Ultra 5G, goes all the way to 100X. At such a high magnification, it can get very tricky to frame shots correctly. especially if you're shooting handheld, which we experienced with the Galaxy S20 Ultra. This is where the new Zoom Lock feature comes in. When you go beyond 20X magnification, you get a little preview window in the viewfinder to help you find your subject better.

The new telephoto lenses along with this zoom lock feature means that zoomed-in shots look better and are slightly easier to capture. The camera app offers the same hard stops at 3X, 4X, 10X, 30X, and 100X, or you can use the slider to pick the exact zoom level you need. The Galaxy S21 Ultra 5G will use digital zoom between 1X and 3X, before it switches to the first telephoto camera, and then again between 3X and 10X when it switches to the second telephoto camera. Image quality is noticeably sharper at the native optical zoom levels, compared to any level in between. At 100X, image quality is comparatively much weaker but AI processing does help in getting usable shots.

In low light, most smartphones ditch their telephoto cameras and just use the primary camera with digital zoom because of their more favourable apertures, but the Samsung Galaxy S21 Ultra 5G will still use its telephoto cameras as much as possible despite their narrow apertures. The results are predictably poorer, but if you use them with Night mode, the results are surprisingly good. In such cases, the zoom range is limited to 10X and the phone sticks to the 3X telephoto camera even at that level, since the 10X camera has a very narrow f/4.9 aperture. I managed to get very good shots from the telephoto camera at night. Here some sample of camera, Which is taken by different angle and different lenses uses.

SAMSUNG GALAXY S21 ULTRA 5G DISPLAY AND BATTERY 

The 6.8-inch AMOLED display gets incredibly bright, and colours look rich and punchy. The QHD+ resolution offers very good sharpness, which is useful when reading text. The biggest new feature is that you can use the 120Hz refresh rate at the native resolution. It's also adaptive, which means when no touch input is detected, or if you're watching a video, the refresh rate automatically scales down to 60Hz. Samsung says it can go down all the way to 10Hz to save power.

Videos in general look great on the Samsung Galaxy S21 Ultra 5G's display. Watching dark scenes in movies isn't a problem as the AMOLED panel can achieve impressive black levels. Audio from the stereo speakers is also very good thanks to the Dolby Atmos enhancement. You get high-fidelity audio playback with support for the DSD 64/128 and 32-bit PCM formats over a wired headset.

Other flagship features include an IP68 rating for dust and water resistance, Samsung Pay via NFC and MST, and a whole lot of sensors including a new-generation ultrasonic fingerprint sensor. Samsung claims this is about 1.7X larger than the previous model, and in my experience, it worked very well. All that's needed is a quick tap for successful authentication. Face recognition is supported too, and is also reliable.

The 5,000mAh battery capacity is the same as what the Galaxy S20 Ultra had, and easily lasts for more than a full day of heavy to medium usage. With lighter use, I was able to prolong the battery life to a little more than a day and a half. This was with the display set to QHD+ and the 120Hz adaptive refresh rate enabled. The Samsung Galaxy S21 Ultra 5G lasted for 15 hours and 37 minutes in our HD video loop test, with the screen at the default resolution (full-HD+).

The Galaxy S21 Ultra 5G supports fast charging but only at up to 25W, with a compatible USB PowerDelivery (PD) Type-C adapter. This is something you'll have to buy separately, either from Samsung or a third party vendor, since you don't get a power adapter in the box anymore. In fact, you get only a USB Type-C cable and the SIM eject tool.

Samsung Galaxy S21 Ultra 5G software

The Samsung Galaxy S21 Ultra 5G runs OneUI 3.1, and it worked smoothly with no real hint of lag or slow-downs in the week that I had to review this phone. This is the latest version of Samsung's custom skin, and is based on Android 11.
