Choose a smartphone is becoming increasingly difficult, this is true, but I assure you that with a bit of attention you can juggle between many technical specifications, the abbreviations and the "numbers" of the devices on the market without being technology experts .
Try to follow the instructions I am about to give you and the embarrassment that now assails you when you look at the shelves of an electronics store should disappear. I do not say you manage to find the perfect phone for you right away - because there will certainly be many - but at least you will reduce to a minimum the possibility of making the wrong purchase. It is no small thing, believe me!
Shape, appearance and design
A smartphone with a large screen is more uncomfortable to carry in your pocket or handle than a phone more compact size. I meraviglierò, but this statement is not always to be false.
Besides the size of the display - which plays a key role in choosing a smartphone - before buying a phone you have to take into account other aspects, such as the thickness of the device, its weight and its grip , ie the convenience of the socket.
A smartphone 5 "thin, light and with a good grip - maybe dictated by rounded edges - can be infinitely more comfortable than a 4" thicker, heavier and with sharp corners. In short, do not stop at the size: assessing the combination of all the physical and aesthetic characteristics of the device.
As for construction materials: smartphones with a metal shell, type the Apple iPhone or the Samsung Galaxy S6, they are more pleasant to the touch and cared for; in short, they are more "fine". However those made of plastic (a good plastic) may be equally valid, pleasant to the touch and are less prone to scratches or dents. Its up to you to choose the right type of phone to your needs.
The display of the characteristics to be taken into consideration before choosing a smartphone are at least four: type, size, resolution (in pixels) and density of pixels per inch (ppi).
The resolution and the pixel density is not much to say: the more extensive, more pixels there are, the better (as the pictures and the words are sharper). We can only make a note about the real usefulness of QHD or 2K screens , which have a resolution of 2560 × 1440 pixels which is certainly greater than Full HD (1940 × 1080 pixels) but hardly their benefits you can see with the naked eye.
The size , however, you have to make subjective judgments: over 4.5 "becomes objectively difficult to use smartphone with one hand, however, as mentioned before, are taken into account other elements to judge the degree of comfort or handling of a telephone. From 5.1 "up talking about fable , or hybrid devices, including smartphones and tablets.
Now, however, we analyze the various types of screen that we can find on smartphones on the market and their main features.
- LCD display - can be TFT type or IPS. The LCD TFT screens are often used in low-cost device. They provide a generally good image quality, but have problems with the colors, which are washed out when you change the viewing angle. Also they consume a lot of battery. The LCD screens IPS (like the iPhone) consume less power than TFT and provide more vivid colors, even when you change the viewing angle.
- AMOLED display - are present on many smartphones midrange and high (such as the Samsung Galaxy) and ensure low fuel consumption thanks to the fact that the pixels do not require backlighting. This means that the black color content played on the screen are formed by the pixels "off" which are not borne on the cell phone battery. Ensure a very good color reproduction, even when you vary the angle of vision, but they are a bit 'more "opaque" IPS (this also makes them slightly less visible under sunlight). The AMOLED display of the latest generation, called Super AMOLED, offer greater brightness and suffer from less sunlight.
- Triluminos display - is a Sony technology based on the TFT. Ensures an increase of about 50% in the amount of reproducible colors of the screen with respect to the TFT LCD, while as regards the viewing angles, it is still not at the levels of the IPS and AMOLED screens.
Other hardware features
Other features to consider before buying a smartphone is that relating to the kind of memory which is equipped with the device, the amount of RAM available to it, the battery and the type of camera.
- Storage capacity - the capacity of a smartphone storage, to which commonly refer to as "memory," it can be expandable or non-expandable. Expandable memory when it comes to the ability of the device storage (in GB) can be expanded by using MicroSD cards.
- RAM - amount of RAM on a smartphone determines its ability to handle more simultaneously (multitasking). Nowadays 1GB of RAM is the "minimum wage" for Android terminals while it is still not enough on top of Apple and Microsoft range (thanks to their software optimizations).
Battery - the power of a battery is expressed in milliampere / hour (mAh). This means that the greater number of mAh, and the greater the autonomy of the phone (at least theoretically).
Camera - the parameters on which the performance of a camera should be evaluated are different: the number of megapixels (ie the resolution of photos taken); the presence or absence of the Flash; the aperture (which indicates the level of sharpness of the shots taken in the dark); the technology used for the image stabilization, and more. My advice is to search the Internet for examples of photos taken with the terminals that interest you and assess what is the best according to your very own yardstick.
- Supported networks - all smartphones are now able to connect to the 3G data network and the Wi-Fi type b / g / n networks. Those a bit 'more advanced are also able to connect to the data network 4G / LTE (which is much faster than that of 3G, but requires special tariff plans) and to wireless networks, and dual-band AC that also operate in the frequency 5GHz (as well as on the standard 2.4 GHz used by wireless networks b / g / n). As for the 4G / LTE connectivity, we must also pay attention to the frequency bands supported by a mobile, especially those imported. Many smartphone products in China, in fact, does not have support for the 800MHz frequency band that some Italian operators use for the network 4G / LTE (which makes the fast connection unusable in certain areas).
- Dual-SIM support - dual-SIM phones are the ones that allow you to use two SIM cards simultaneously, and then have two mobile phone numbers on the same phone number. Beware, though, are not all alike! The dual-SIM are divided into smartphones Dual-SIM Dual Standby and Dual-SIM phones Full Active: first, who are the majority, making it the second SIM unreachable while the former is engaged in a call; seconds instead keep the two always active SIM. Regarding the Internet, the majority of dual-SIM devices using 3G / 4G connection on the primary SIM and connection 2G (which just only for calls) on the secondary SIM. Very often it is possible to carry out a "hot switch" of the 3G / 4G connection by passing from one SIM to another using the menu of the phone (and then via software), but in some cases the SIM must physically pass from one to another slot as only one of them supports the 3G / 4G network. Another important thing to know is that some of the terminals of the second SIM slot are shared with that of the MicroSD, so you have to choose whether to expand the memory of the phone or if you use two SIM (you can not do both simultaneously).
A sensor for detecting the fingerprints - some smartphone models, generally those higher-end models are equipped with a biometric sensor for fingerprint detection that allows you to unlock the device, confirm the purchases in store and authenticate various apps simply placing the finger on the phone (or rather, on the sensor).
A smartphone is not just hardware, indeed. The software is playing an increasingly important role in the performance and the experience of the use of a telephone, then, please, before you choose a well-informed on the device's operating system.
Google Android - is the most popular smartphone operating system in the world. You can count on an application pack and really endless games and gives a lot of freedom to the user. You can customize every aspect, so much so that many manufacturers equip their phones with custom versions of the operating system and additional applications (sometimes slow down the functioning of cells). Among its downsides are the greatest risk of malware compared to other mobile platforms and fragmentation with which manufacturers distribute updates released by Google (which does not arrive at the same time on all terminals).
Apple iOS - as easy to understand, this is the iPhone OS. It is customizable and flexible as Android, but offers an application park and even larger games (with a higher average quality). Updates arrive on day one on all of "iPhone by" models supported and the risk of malware is virtually nil.
Microsoft's Windows Phone - is the Windows Mobile version. He has not yet had much success and this makes its own application park and games still pretty lackluster. It is free from malware and also is very quick on economic terminals. The updates come in a more fragmented than iOS but more organized compared to Android.
