The Galaxy Xcover is in fact equipped with Android 2.3, WiFi and 3G Internet, integration of social media and a 3.2-megapixel camera. Prices starting at: €249 Available at: ELECTRONICS,MAP 3. The Samsung Galaxy S21 Ultra has a 6.8-inch OLED screen with curved sides. That curve isn’t as pronounced as the OnePlus 8 Pro’s or Oppo's Find X2 Pro. A dramatic bend makes a display look futuristic and fancy, but it’s probably good news for image quality as a lighter one means you don’t get such clear dimming in the last millimetre or two of the screen. S Pen is not charging on my Galaxy Note or tablet. The S Pen's wireless functions are powered by Bluetooth, and the S Pen will need an occasional charge to keep. Shop for Occasional Galaxy Chair.

If a high-end smartphone like the Samsung Galaxy S10 Plus keeps lagging or became sluggish, then there could be an issue with its firmware. Performance problems are often tied to system issues.

Samsung Galaxy S21 has managed to impress us with what it brings to the table, especially in terms of raw firepower and camera capabilities. However, one aspect that really out for me was the phone’s fresh design, especially that dual-tone finish. The device is also IP68-rated, which means it means it can survive a few occasional dunks inside a bucket of water. What that ingress protection doesn’t ensure is security against scratches and accidental falls. Naturally, a case is the best choice here, but at the cost of hiding its sweet design. This is where clear cases come to the rescue. And to save you the trouble, we’ve rounded up the best Galaxy S21 clear cases:

ESR Clear Polymer Case

Featherlight

I can say from personal experience that the ESR Clear Cases is one of the thinnest protective solutions for phones. This shock-resistant case also has raised edges to protect the camera island and display.

ESR Metal Kickstand Case

Added versatility

Another excellent option from ESR, this shock-absorbent case has a smudge-resistance clear surface. Plus, the dual-mode kickstand lets you place the phone in both portrait as well as landscape orientation.

Ainoya Clear Grip Case

Great grip

The shock-proof Ainoya Clear Grip Case has ridged sides and padded corners for added protection against accidental falls from a height of up to 6 feet. There is an oleophobic coating at the back too.

IVSO Clear case

Multi layer shielding

The IVSO offering provides dual-layer protection, has an antioxidant layer to stop yellowing and has shockproof corners. Plus, it comes with a screen guard that can handle falls from up to 20 feet.

Arae Clear Case

Drop protected

The Arae Clear Case for Galaxy S21 comes with a tad too pronounced corners that are claimed to offer superior protection against bumps. Plus, the corners are hardened to resist deformation over time.

BAISRKE Case

Frame fit

Made out of high-quality TPU and polycarbonate, the BAISRKE clear case for Samsung Galaxy S21 has an anti-scratch frame and offers military-grade protection. The raised lips on both sides are an added safety.

Temdan Case

The sturdiest

Temdan’s clear case for the Samsung flagship features a precision molded frame to offer the highest degree of protection againt mechanical impact. Plus, it also comes with an in-built screen protector.

Restoo Case

Edge protected

Instead of relying on protruding corners with air cushion, the Restoo case instead opts for a uniformly thick frame that offers better shielding also looks clean. And oh, the raised lips will offer more safety.

Pulen Case

Budget option

The cheapest option on this list, the PULEN clear case doesn’t cut corners when it comes to protecting your pricey flagship. Made out of soft gel, it has raised corners and bezels for maximum protection.

Those were our top picks for the best Galaxy S21 clear cases. However, if I were to pick a favorite, I would go with the ESR metal kickstand case. Made out of durable polycarbonate, the ESR case is quite thin and has padded sides to protect against bumps and scratches. The best part about it is the metal kickstand at the back, which lets you place the Galax S21 on a flat surface in both portrait and landscape orientation. Plus, the angle lets you make angular adjustments within a 60-degree range.

However, if you don’t want to drop a lot of money on a clear case, the PULEN clear case will serve the purpose for less than eight bucks. Made out of soft silicone, the PULEN case will protect your phone against dirt, smudges, and scratches. Plus, the raised corners and bezels on both sides ensure that the device can brush off mechanical impact and abrasive forces.

Occasional Galaxy

Galaxy, any of the systems of stars and interstellar matter that make up the universe. Many such assemblages are so enormous that they contain hundreds of billions of stars.

Nature has provided an immensely varied array of galaxies, ranging from faint, diffuse dwarf objects to brilliant spiral-shaped giants. Virtually all galaxies appear to have been formed soon after the universe began, and they pervade space, even into the depths of the farthest reaches penetrated by powerful modern telescopes. Galaxies usually exist in clusters, some of which in turn are grouped into larger clusters that measure hundreds of millions of light-years across. (A light-year is the distance traversed by light in one year, traveling at a velocity of 300,000 km per second [km/sec], or 650,000,000 miles per hour.) These so-called superclusters are separated by nearly empty voids, and this causes the gross structure of the universe to look somewhat like a network of sheets and chains of galaxies.

Galaxies differ from one another in shape, with variations resulting from the way in which the systems were formed and subsequently evolved. Galaxies are extremely varied not only in structure but also in the amount of activity observed. Some are the sites of vigorous star formation, with its attendant glowing gas and clouds of dust and molecular complexes. Others, by contrast, are quiescent, having long ago ceased to form new stars. Perhaps the most conspicuous activity in galaxies occurs in their nuclei, where evidence suggests that in many cases supermassive objects—probably black holes—lurk. These central black holes apparently formed several billion years ago; they are now observed forming in galaxies at large distances (and, therefore, because of the time it takes light to travel to Earth, at times in the far distant past) as brilliant objects called quasars.

The existence of galaxies was not recognized until the early 20th century. Since then, however, galaxies have become one of the focal points of astronomical investigation. The notable developments and achievements in the study of galaxies are surveyed here. Included in the discussion are the external galaxies (i.e., those lying outside the Milky Way Galaxy, the local galaxy to which the Sun and Earth belong), their distribution in clusters and superclusters, and the evolution of galaxies and quasars.

The dispute over the nature of what were once termed spiral nebulae stands as one of the most significant in the development of astronomy. On this dispute hinged the question of the magnitude of the universe: were we confined to a single, limited stellar system that lay embedded alone in empty space, or was our Milky Way Galaxy just one of millions of galaxies that pervaded space, stretching beyond the vast distances probed by our most powerful telescopes? How this question arose, and how it was resolved, is an important element in the development of our prevailing view of the universe.

Up until 1925, spiral nebulae and their related forms had uncertain status. Some scientists, notably Heber D. Curtis of the United States and Knut Lundmark of Sweden, argued that they might be remote aggregates of stars similar in size to the Milky Way Galaxy. Centuries earlier the German philosopher Immanuel Kant, among others, had suggested much the same idea, but that was long before the tools were available to actually measure distances and thus prove it. During the early 1920s astronomers were divided. Although some deduced that spiral nebulae were actually extragalactic star systems, there was evidence that convinced many that such nebulae were local clouds of material, possibly new solar systems in the process of forming.

The problem of the Magellanic Clouds

It is now known that the nearest external galaxies are the Magellanic Clouds, two patchy irregular objects visible in the skies of the Southern Hemisphere. For years, most experts who regarded the Magellanic Clouds as portions of the Milky Way Galaxy system separated from the main stream could not study them because of their position. (Both Magellanic Clouds are too far south to be seen from most northern latitudes.) Moreover, the irregular shapes of the objects and their numerous hot blue stars, star clusters, and gas clouds did indeed make them resemble the southern Milky Way Galaxy.

The American astronomer Harlow Shapley, noted for his far-reaching work on the size and structure of the Milky Way Galaxy, was one of the first to appreciate the importance of the Magellanic Clouds in terms of the nature of spiral nebulae. To gauge the distance of the Clouds, he made use of the period-luminosity (P-L) relation discovered by Henrietta Leavitt of the Harvard College Observatory. In 1912 Leavitt had found that there was a close correlation between the periods of pulsation (variations in light) and the luminosities (intrinsic, or absolute, brightnesses) of a class of stars called Cepheid variables in the Small Magellanic Cloud. Leavitt’s discovery, however, was of little practical value until Shapley worked out a calibration of the absolute brightnesses of pulsating stars closely analogous to the Cepheids, the so-called RR Lyrae variables. With this quantified form of the P-L relation, he was able to calculate the distances to the Magellanic Clouds, determining that they were about 75,000 light-years from Earth. The significance of the Clouds, however, continued to elude scientists of the time. For them, these objects still seemed to be anomalous, irregular patches of the Milky Way Galaxy, farther away than initially thought but not sufficient to settle the question of the nature of the universe.
