In this article, we'll talk about external signs that should be used when choosing a modern smartphone on Android.
Sizes can now be found in a wide variety, ranging from 3 inches to giants.
Typical representatives of small smartphones on Android, with screen sizes from 3 to 4 inches - a line of HTC Desire, Samsung Galaxy Ace and others. Basically, they are inexpensive, in terms of performance at a low or medium level. Such devices are quite convenient in everyday use and fit almost into any pocket or purse.
Devices with sizes over 4 inches, usually have a high performance and are called flagships. They are also distinguished by high cost and, as is clear from the screen size, not small overall dimensions. In everyday use, they are not always convenient, especially for owners who do not have a big hand, because managing one hand with them will be hard. It is also worth noting that many representatives of this category of devices, sometimes even do not fit in a simple pocket of jeans. But, thanks to the size, they are great for small office work (checking mail), Internet surfing and spending time in the most modern 3D games. Typical representatives of such smartphones are Samsung Galaxy, HTC One, LG Optimus and others.
The type of screen, or matrix, is responsible for how realistic and juicy colors you will see from the screen of your smartphone. The most common ones are TFT, LCD, IPS and AMOLED.
The most simple matrix is the TFT. It is used in budget Android smartphones. Has not high angles reviews, enough bad, but realistic color rendition. Often, because of lack of brightness, screens on such a matrix are very poorly visible in the sun. But there are some exceptions, for example TFT-matrix installed on Sony phones. The Japanese manufacturer brought it to perfection and at the output one can see the best realistic picture, with good colors and a high, even excessive margin of brightness.
LCD and SuperLCD are the most common matrices. They are actively used by HTC, Samsung (in younger models) and other manufacturers. They are some sort of intermediate option, providing a sufficiently high-quality image on your smartphone.
IPS matrix, in most cases can be seen on smartphones from LG, mainly on models of medium and high class. This matrix is famous for its realistic color rendering and excellent viewing angles. In addition to Android devices, it is often used to create special monitors for designers.
The last matrix - AMOLED, is the development of Samsung. It provides a very juicy display of colors, even too juicy. For some, this is a minus. In addition, the screens with this matrix almost never fade in the sun. The AMOLED matrix and its varieties are the best offer on the market at the moment.
The screen resolution is how many dots, or pixels per inch you have. The more this value - the more quality picture you get. For example, with a small resolution you can easily see on the wallpaper of your screen graininess, pixels.
Like the screen size, the permissions are great. The minimum is 240 by 320 points. Usually the screen resolution corresponds to its diagonal. For example, on 3-inch devices it is installed either 240 by 320 points, or 320 by 480. On smart phones with a larger diagonal, up to 4 inches, you can meet as much as 540 by 960 pixels (Sony Xperia P, Huawei Ascend P1). And starting at 4.3 inches, HD resolution is 720 at 1280.
Manufacturers of modern smartphones protect the smartphone screen in different ways. Typically, the protection level depends on the class of the device.
Not expensive Android-smartphones are equipped with a regular glass on top of the matrix. The level of protection at them is low and on them it is recommended to glue a special film.
Devices are higher in the price category most often, already have a special protective glass Gorilla Glass of the first or second generation. It provides a very good level of protection against any external influences, so the sticker of the film is not necessary.
Some manufacturers use other developments, for example, Sony. On their devices series Xperia installed tempered glass, which, like Gorilla Glass, provides a very high level of protection. Plus, the manufacturer independently at the factory puts very high quality films on the screen, which, of course, is a big plus.
Keyboards on Android-smartphones are divided into two types - sensory and physical. The physical is understood as the so-called QWERTY keyboard, located usually under the screen of the phone, and leaving there if necessary.
The touch keyboard is a keyboard, drawn on the screen of the device itself. That is, to type some text, we need to press not on the keys, but on the screen. Representatives of smartphones with a similar keyboard are great and there are no examples to give examples, but the owners of full-fledged physical (QWERTY) are very few and here is their small list: Samsung Galaxy Y Pro, LG GW620, Alcatel One Touch 910 and OT-916D are on sale now . If you're lucky, you can dig out somewhere SE Xperia Pro, Mini Pro, HTC Desire Z and Motorola Milestone. Officially, they are no longer on sale.
Most smartphones use the following materials: plastic, aluminum, soft-touch and polycarbonate. Everyone is something good.
Plastic is the most common. It is light, cheap, the back covers of it are easy to find in the store for replacement.
Soft-touch is a kind of plastic, only a little rubberized. This material is very pleasant to the touch and quite resistant to serious damage, but it easily scratches on sharp objects.
Aluminum is considered a premium material, which is used extremely rarely. This is primarily due to high thermal conductivity, and Android-smartphones are decently heated with active use, and aluminum also interferes with NFC technology.
Polycarbonate is a material very often used in flagships. Resistant to all types of damage, pleasant to the touch and has a fairly respectable and expensive appearance.
When choosing a smartphone, pay attention to the connectors on it. This will in the future avoid problems with the long search for a cord or headphones with the necessary connector.
Must be the presence of the following connectors: 3.5mm for headphones, MicroUSB or at the very least - MiniUSB. This choice is due to the fact that most accessories (headphones, headsets, various wiring for connecting to something, docking stations) are manufactured just under these connectors.
In addition, it is recommended to pay attention to the presence of a connector for a memory card. If it is not - make sure that the smartphone has at least 16 gigabytes of internal memory. This, you can say, the minimum volume for comfortable use of the device on Android
Now almost all smartphones with the Android operating system are installed as a front camera, and the usual front. Actually the first one is necessary for video communication (Skype), and the second one is for normal pictures.
The front camera has a different resolution. If you do not plan to use video communication regularly, then you should not pay attention to this characteristic at all. If there is - it is recommended to take devices with a front camera.
As for the usual camera for pictures and video, then most often on the shelves you can see smartphones with two kinds of matrices.
