In the 90s, a cell phone was considered a subject of special pride and “coolness”, who had it. The connection was disgusting, and the cost of the first mobile phones and cellular services connections are “just cosmic”. But since that distant and difficult time, a lot of “water has flowed under the bridge” and now you won’t surprise anyone with a mobile phone, even deep old people and small children of preschool age use cellular communications.
Here is how you can evaluate a smartphone features and buy one for yourself:
Memory
RAM
The internal memory of a smartphone consists of a block of operational and permanent. The larger the amount of RAM, the greater the system performance will be and, therefore, the more simultaneous tasks the smartphone can perform without freezing. Today, the amount of RAM reaches 8 GB in the most “advanced smartphone models”. For daily tasks and entertainment enough from 64 MB to 128 GB of RAM.
Persistent memory
The permanent memory of a smartphone is designed to install programs and store various multimedia and other data. It is not reset when the device is discharged or turned off. The maximum amount of permanent memory can reach 64 gigabytes.
Be sure to pay attention to the possibility of expanding the memory – the presence of a slot for memory cards. This will additionally help expand the memory of the device by 64 GB or even 128 GB (depending on the model).
Camera
For a very long time, the presence of a camera in a mobile phone was perceived by us as “an extra and not very necessary function.” Pictures taken by a phone with a camera of 0.3 megapixels or even 2 megapixels were of such “poor quality” that they could only be viewed on the phone itself.
Therefore, a “mobile phone with a camera” has never been a competitor to a good digital camera. But it is now a great competitor with modern phones like Honor x9.
But with the advent of modern smartphones, a revolution has taken place in photography. Cameras with a resolution of 16 megapixels (the number of pixels of the matrix), which are installed in modern smartphones, are on par with digital cameras of similar parameters in terms of image quality.
Operating system
To date, the most widely used operating systems: are Android, iOS, Windows Phone, Blackberry & Symbian, etc.
Android
Android is an operating system from Google. Used on various mobile devices: smartphones, tablets, netbooks, e-books, multimedia players, etc.
A very large number of smartphones support this particular operating system, try to buy a device that runs on the latest versions of Android, as many modern applications only work under the “latest versions of Android”.
Android has a lot of advantages:
- Downloading applications from the Google Play online market.
- Convenient synchronization with Google services.
- Ability to install applications from a memory card without using a computer or laptop and from alternative sources.
- Devices running Google Android can be connected to a computer like a regular removable drive and transfer data by simple copying.
But there are also disadvantages: The Android operating system is very often vulnerable in terms of information security, and it is often updated, which leads to the appearance of similar devices, but with different software versions. This leads to program incompatibility.
iOS
iOS is Apple’s operating system, which is installed only on their devices (these are the famous iPhones and iPads), these devices have a huge army of fans, and they have their own “pros and cons”. But the cost of “apple products” is much higher than analogs from other brands.
Applications are installed from the Internet, or using the Apple Store service after registration. Phones are synchronized with the computer exclusively using iTunes, without which it will not be possible to get quick access to the device’s memory.
Window Phone
Window Phone is an operating system from Microsoft Corporation. The advantages of this operating system include high compatibility with Microsoft Office documents that are edited both on PCs and on mobile devices.
Symbian
Symbian is an operating system designed specifically for smartphones. Nokia smartphones and devices from some other manufacturers work on this platform. There is support for multitasking, and functions for working with multimedia and the Internet are also implemented. Quite common in smartphones without a touch screen.
Blackberry
Blackberry OS is an operating system from RIM. It is installed on smartphones only by this manufacturer (Blackberry). The main advantage of Blackberry devices is the ability to encrypt e-mail and Internet traffic. But these advanced encryption and security features do not work in all countries.
