RAM
The amount of random access memory (RAM) installed in the tablet. This memory is used for direct data processing, and therefore its volume is one of the main indicators of system speed and power. However note that the optimal amount of RAM strongly depends on the OS used — different systems and even different versions of the same "OS" can vary greatly in terms of consumed resources. But models on the same OS can be compared with each other in terms of the amount of RAM.
As for specific values, indicators in
1 GB or less in our time are definitely a sign of a weak tablet.
2 GB and
3 GB can be called the entry level,
4 GB and
6 GB are middle class, and in the most advanced models,
8 GB, or even
16 GB can be installed (or even more) RAM.
Max. memory card storage
The largest amount of memory card with which the tablet is able to work correctly. For more information about the cards themselves, see "Memory Card Slot"; here we note that capacious media often use advanced technologies that are not supported by early models, and sometimes tablets simply do not have enough power to process large amounts of data. Therefore, for the convenience of choosing in our catalog, the maximum supported volume is indicated.
In fact, there are cases when some devices may exceed the claimed characteristics — for example, work with 8 GB of media with the claimed 4 GB of maximum capacity. However, it is worth focus on official data, because. if they are exceeded, normal operation with the card is not guaranteed.
Main
— The number of lenses. The characteristics of the main (rear) camera of the tablet are represented primarily by the number of modules, which in most cases are 1, but there are also
tablets with a dual camera.
— Resolution. The second important factor of the camera is the number of megapixels. Many really believe that the more MP, the better the quality of filming. However, this is not entirely true: only the maximum resolution of the resulting images depends on the resolution of the matrix, and their quality is determined by many other parameters. However a large sensor resolution may be a sign of an advanced camera, but this is not necessary — two "eyes" with the same number of megapixels can radically differ in the quality of shooting.
Rear cameras in tablets may well be used for photo and video shooting; therefore, they have
cameras of 8 MP,
10 MP and even higher (
12 and
13 MP).
— Autofocus. For focus in such cameras, a movable lens system controlled by automation is responsible. It takes some time for the automation to work, and the lenses themselves turn out to be more complicated and more expensive than optics with a fixed focus (fixed lenses that are initially set to a large range of distances). However, the quality of the pictures i
...s disproportionately higher than that of cameras without autofocus, and the systems themselves are constantly being improved, and their response time is increasingly approaching instantaneous.
— Flash. Flash significantly expands the capabilities of the camera. First of all, it allows you to shoot in low light conditions; in this case, the backlight, usually, can also be used in the constant glow mode — for video shooting. The second situation where a flash can come in handy is backlighting when the subject is in shadow. In addition, in many tablets, the flash LED can also be used as a regular flashlight, without a camera.Full HD filming (1080p)
The resolution and maximum frame rate provided by the main camera when
recording Full HD (1080p) video at normal speed, without slow motion (if available).
The standard resolution for this format is 1920x1080. Note that this can be either the maximum shooting resolution or one of the relatively simple options in addition to more advanced standards (such as UltraHD 4K). At the same time, Full HD is considered more than a decent resolution by modern standards, and at the same time, it can be supported even by fairly simple and inexpensive tablets.
As for the frame rate, there are actually two values in normal shooting - Full HD 30 fps and
Full HD 60 fps. A higher frame rate allows you to achieve very smooth display of dynamic scenes - even fast-moving objects in the frame are seen as clearly as possible, with almost no blurring. However, the low shooting speed also has its advantages - it allows you to reduce the amount of material being shot. Therefore, tablets that support 60 fps may have the ability to reduce the frame rate to 30 fps. But speeds above 60 fps are already used for shooting slow-motion video (slow-mo); see "Slow-mo" for more on this.
Battery capacity
The capacity of the battery that is normally installed in the tablet.
Theoretically, a larger battery means longer battery life. However, in fact, the battery life of the tablet also depends on its power consumption — and it is influenced by the characteristics of the processor and screen, the installed OS, and other factors. Therefore, only models with similar characteristics can be compared in terms of battery capacity (and even such a comparison will be quite approximate); and to assess battery life, it is best to look at the directly claimed operating time in different modes.
Compatible stylus
A rare tablet model comes with a stylus. Sometimes it’s easier to buy it separately in order, firstly, to save on the initial purchase of the gadget, and secondly, to understand how the device works and understand whether you still need a pen or not. Naturally, different brands and models have their own such accessories. Of course, all kinds of styluses from different manufacturers can perform basic operations, but only compatible ones can provide full functionality.
