Currently there are countless models of tablets, ranging from 7 inches and above, without compromising the operating characteristics, price and other system. Knowing what tablet to buy is a difficult question to answer, but we will help you with these buying tips.
1: Demand for tablets
The segment of the tablets belonging to the Android universe is growing at a very high rate in recent years. This, at first glance, may seem a big advantage, but it also has its drawbacks. And it is that with so much variety, sometimes it’s hard to choose what tablet to buy, what features are really important and if the sales price is right based on the materials and performance.
The combinations are endless: size, screen type, hardware, operating system, storage capacity, camera, connectivity, etc. Therefore, the best advice when buying a tablet is that the best option is one that fits your needs and especially your pocket, keeping the minimum benefits for each use.
Therefore, let us analyze the possibilities that exist in the market for tablets.
2: Size and type of display
When considering what tablet to buy, two questions we must ask ourselves above any other. These are: What screen size do I need? What operating system do I like better, or fits my needs?Although the boom we have experienced in this segment make the screen sizes vary from 7 inches up, including 19.5 inches (or more). For example, Lenovo Flex 20 , is said to have two preset sizes, the 7 inch tablets and 10 inch tablets.
When choosing between them, it must be clear what you’re going to use. If you are looking for a mobile device, take the subway for example, to read, see social networks, and for entertainment use, perhaps the ideal is to focus on the segment of 7 inch tablets . The reasons are none other than their lower price, ease and convenience for carrying and handling with one hand. On the other hand, if you’re looking to give it a more professional use, as a second computer, used for text editing, sending and receiving post, meetings and so on, you may have to look for a bigger tablet around 10 inches. Also, many models of these dimensions also offer a number of accessories that improve productivity, such as keyboards, cases with extra batteries, etc.
The second important point is the screen quality. Some time ago it made sense to mention that capacitive screens were much better than resitivas, but today, since hardly any manufacturer uses the latter, even so, just in case, never buy a tablet that has resitiva screen , for the sensitivity and accuracy is much lower.
Another big question is the type of glass used. Currently we can find screens LCD, TFT, IPS, LED, AMOLED, SUPER AMOLED and Retina, the last one being the best.
Once we have resolved the issue of size and type of screen, the issue arises about resolution, where many think higher resolution, better image quality. But it is not always so.
And it is that the higher resolution has a better screen you will see, but always depending on the size of your screen. That is, a larger screen, higher resolution needed for image quality does not suffer.
The screen resolution is the number of pixels that can be displayed on the screen, “number of pixels of length” x “number of pixels of width” .
However, depending on the format and screen size this can create doubts, because it is difficult to decide what amount of pixels is suitable for every screen size and thereby we also have pixel density per inch (dpi) to indicate the number of points of light per unit area.
Another consideration is the format of the screen, this can be 4: 3, 16: 9 or 16:10, being a matter more than personal or aesthetic taste than functionality.
But we must not forget that a higher density and resolution means higher energy consumption. As the resolution is increased, the number of pixels that the screen has to play is also increases, so that when consulting density and resolution, we must also look at the battery and autonomy of the tablet.
Hardware refers to all tangible parts of a computer system, electrical, electronic, electromechanical components and/or mechanical. Here we focus on:
This is one of the most difficult points to explain, however, as manufacturers usually only provide information about the processor name, number of cores and clock frequency to working, we will focus only on these three aspects.
The clock frequency of any processor is the unit of measurement indicating the number of operations that the CPU can do per second and is measured in hertz (HZ). Not because a processor has more or less gigahertz will be more or less quicker than others, and it also influences the number of cores.
And it is that we can currently find on the market with chips with a single core, the dual core and quad core, now used in high-end mobile, that although they are more powerful, also consume greater amount of energy and therefore the battery should be compensated.
Currently the most common processors are those that use the ARM architecture, i.e. Qualcomm, Cortex, NVidia, Mediatek, or Exynos.
On the other hand, there are times you will also find the name of the GPU, which is responsible lighten the workload of the processor on graphics for 3D games or applications. The most common are Qualcomm Adreno, Mali ARM, Power VR and NVidia Tegra.
Clearly these, the vast majority, tablets in middle, upper-middle range, and for example, will not see any of them in the Chinese tablets.
It is named for its acronym in English, “random access memory”. It serves as a working memory for the operating system, programs and software. A greater number of faster RAM will be processing data as more data can be stored on it and more applications can be running at the same time without slowing down the tablet.
In addition, you should note that applications will evolve and increasingly requiring the tablet.
The internal memory is the space dedicated to allocate all your files, such as photos, videos, music and other applications you download into the tablet. Note that the manufacturer will give the total internal memory, which is not the same as is available as software and internal applications occupy an external space on the hard drive of your tablet .
The space required depends heavily on the uses that go to give the device because in most cases, 8 or 16 GB is usually more than enough to store all this.
One should also take into account that most tablets on the market offer a slot for memory cards microSD/microSDHC, to expand storage. These are purchased separately and are relatively inexpensive.
The software is one of the key issues when choosing which tablet to buy. There are currently three operating systems for tablets that stand out for enciman any other, Android, iOS and Windows Phone.
It is the operating system of Apple, and was born as specific software for the iPhone (iPhone OS), but later was used in iPod Touch, iPad and Apple TV.
This is a restrictive and exclusive software that can not be used in any other brands.
|Simple and clear interface||Hardly customizable|
|Extensive catalog of apps||Absent of Flash support|
It is the most popular operating system in all, but its advantage in the segment of the tablets is not as overwhelming (60%) as in smartphones (80%).
It is a software based on Linux and belonging to Google and has the advantage of offering a wide range of manufacturers, products and applications. In fact, its catalog is so great, that even if you are looking for an Android tablet for less than 150 dollar, you will find many options.
|Highly customizable||Some Apps are not optimized for large screen|
|Broad portfolio of manufacturers, devices and applications||System consumption is high|
|Multi-process||Slowdown for multitasking|
It is the third option, its market share is still far from the big two, but there is no doubt that the new Microsoft operating system for tablets Win10, has certain key advantages, as their environment does not change too much with respect to a “Windows” operating system with which we have spent years working, besides the undeniable plus offered by the presence of native form of Microsoft Office .
|Multi-process||Limited number of applications|
|Integration with Windows software||The Windows version is extremely restrictive|
|Metro desktop environment||Hardly customizable|
Although the camera may not be a tablet or main feature decisive element when choosing which tablet to buy, in fact, it is not, we must bear in mind that having many megapixels does not guarantee the quality of the camera.
The quality of the photographs influenced by other factors is more important than its own megapixels figure, such as the size and type of sensor, optical zoom, ISO sensitivity and the presence of flash, and so on.
Anyway, and for making a quick summary, values the camera as a secondary aspect, without the number of megapixels is the determining factor, because in the end, is more than likely to use the camera to take pictures improvised to post in your social networks and not as a substitute for your camera.
Another important point is that the available front camera. With it you can make video calls with your family, friends, etc. The quality of this, is also a key factor.
Following our list of tips to buy a tablet, we come to one of the fundamental points, the autonomy.
This depends on many factors, screen size, processor, use WiFi or 3G, etc., and all are parameters difficult to establish.
The simplest is to look at the range specified by the manufacturer, leaving a little side capacity (mah) because it can be a tablet 10 “1080p, quad core processor with 3G enabled and 8,000 mAh have much less autonomy than a 7 inch tablet with a single processor 720p and 7000 mAh WiFi.
Ideally, any tablet that you go to buy, expect a longer duration from 5 to 6 hours of battery life for whatever use you have for it, you are not to be disappointed in that aspect.
Although there are many features of a tablet related to connectivity, mainly the problem when choosing what to buy tablet arise in relation to one aspect, WiFi or 3G.
Typically, you’ll find the same tablet with versions WiFi and 3G. The version with 3G allows to insert a SIM card so you can connect to the Internet from any location with 3G coverage, while those without this option only let you connect when you are in a WiFi network.
The choice between one or the other depends, once again on your personal needs. If you want a device for use in your home or office environment, it can suffice with WiFi. However, if you plan to use them anywhere, bus, train, swimming pool, etc, you will need a 3G connection. Obviously, this option is much more expensive.
There is now a third option, 4G, but so far very few tablets with high speed and this standard still needs much development in many countries, since the coverage is still very limited and does not work perfectly. However it is a popular option to consider getting in the not too distant future.
You can also take into account the NFC technology, which allows instant transfer between two mobile devices, although their use is still primitive.
