The article will provide a list of applications with which you can find out the characteristics of Android gadgets.
How to find out the technical characteristics of a phone, camera on an Android ? How to determine the processor on my gadget? Questions of this kind are often asked by owners of Android . In today's review, we'll give you the answers along with links to relevant apps.
To begin with, let's say that in certain cases, a program you really need downloaded from the Internet does not function, even if you installed it correctly. Why is this happening?
The bottom line is that many unlicensed apps only work on certain phones with certain specifications. Your phone probably does not meet the requirements of such applications, which is why they refuse to work.
So, before using any application, you should understand the capabilities of your phone. You have three options on how to do this:
- Read the instructions that come with the phone (inside the box)
- View information in the phone settings (“ Settings - System - About phone ” - the way for almost all phones). True, here you will need to go to different tabs, the data is given randomly.

- Use a special application that will help you get acquainted with all the characteristics of the smartphone in detail.
In the first two cases, you can figure it out yourself. But we offer the third option because it is the most convenient and even useful.
The principle of operation of the phone “on the fingers”
Why on the fingers? Because before you deal with something complex (for example, the principle of operation of a modern mobile phone), you always need to deal with the simplest things, from which everything started.
The signals in the telephone are electrical. Human speech is a sound signal. The telephone converts sound signals into electrical signals and vice versa.
We speak into a microphone, the membrane vibrates, its vibrations in the magnetic field create a current in the coil, which is transmitted through the wire to the interlocutor. At the other end, the opposite process occurs: current flows in the moving coil of the speaker, which causes the membrane to vibrate and “ripple” the air. As a result, we hear sound.
Now phones can be divided into:
- regular landline phones;
- radiotelephones;
- Cell Phones;
- satellite phones;
- phones operating in IP telephony.
How to find out the model name of a smartphone using third-party applications
The Google Play Market has many programs that can show the most detailed information about your device, including the serial number. Conventionally, they can be divided into two categories:
- benchmarks – applications for testing performance;
- monitors – programs for monitoring the status of a smartphone.
As an example, here are three apps that I like the most.
3DMark
3DMark is a benchmark with which all popular bloggers test smartphones. After installation, the program will automatically detect the device model name. To see it, press the “Device” button on the main screen.
The same section contains detailed information about the performance of the gadget and a specification that presents the technical characteristics.
However, the application only shows general information about the model, which is provided by the manufacturing company to software developers. There is no data for your specific phone number here. In addition, the program does not recognize smartphones.
CPU-Z
CPU-Z is a mobile version of a popular computer program for monitoring the state of the processor. It differs from its “big brother” in that it monitors not only the processor, but generally all components of the device.
The model number can be found in the “Device” section.
Registered users have the opportunity to check their smartphone for authenticity.
The mobile CPU-Z interface is in English.
Droid Hardware Info
Droid Info has more observable parameters than CPU-Z, and there is a Russian language. The model number of the smartphone is displayed on the home screen here.
evolution of the telephone: from Alexander Bell to the present day
Experts interviewed by TASS argue that smartphones are unlikely to change their appearance in the coming years, but have every chance of squeezing laptops and cameras out of the market.
Leading analyst of Mobile Research Group Eldar Murtazin believes that phones will turn into full-fledged laptop computers, to which you can connect an external monitor, keyboard and mouse. They will have a large amount of RAM (there are already eight-core processors with more than 4 GB of RAM). With the advent of the 5G standard (data transfer at speeds of up to 7 Gb/sec), people will begin to abandon Wi-Fi.
Murtazin believes that people’s “dependence” on phones will also increase. Bank cards and magnetic passes will become a thing of the past: they will be installed directly into the phone (such technologies already exist). Perhaps the YotaPhone experiment with two screens will be repeated: “Everything else, for example flexible displays, is exotic, and they are unlikely to be on the market en masse.”
The number of sensors will also remain the same. “A modern smartphone is a full-fledged measuring station, which scientists could not even dream of in the sixties. Therefore, the accuracy of sensors will improve, but not their number,” says Murtazin. He also predicts the further development of applications like Google Now: “Due to the data that smartphones will transmit, it will be possible to predict earthquakes or, for example, people’s behavior.”
Wylsacom Media mobile device expert Alexander Pobyvanets, in turn, believes that the development of flexible displays will bring back non-standard form factors: “These will be extraordinary, fashion devices.” On the other hand, the controls will remain the same as now - touch, and the screen size will increase. The minimum diagonal will be 5.5 inches.
Another pressing problem that future smartphones will be able to get rid of is fast discharge and long battery charge. “There are already fast charging technologies. I expect that in the near future a phone will be fully charged in 20–30 minutes,” the expert predicts. Cameras will also become better - now phones are slightly inferior to DSLRs and have almost killed compact cameras. The trend will continue.
But according to the expert, there is no point in waiting for futuristic concepts on the market yet: “There have been concepts for a long time, for example, a bracelet phone that projects a screen and keyboard onto any surface and reads finger movements. But it hasn’t gone into production yet and won’t in the foreseeable future.”
Converting a talking telegraph into a landline telephone
Bell's talking telegraph went through many metamorphoses before becoming the modern smartphone.
So, in 1877-1878. American inventor Thomas Edison improved the device. He introduced an induction coil into the circuit, and in the microphone he replaced the carbon powder with a carbon rod (such microphones were used until 1980). This made the communication clearer and louder. Now telephones, unlike public telegraphs, have become household devices.
In 1878, the first telephone exchange appeared in New Haven. The following year, Paris took over the baton. Since 1881, telephone exchanges began to open in Berlin, Riga, and Warsaw. In Russia, namely in Moscow and St. Petersburg, they appeared in 1882.

It is worth noting that the first telephone exchanges were manual - the connection was made by a telephone operator. But in 1879, American engineers Connolly and McTight invented an automatic switch. Now people could reach each other by simply dialing a number.
It turns out that in just about half a century the telephone has gone from a pipe dream of inventors and enthusiasts to the most widespread phenomenon, allowing millions of people to communicate at a distance. It is from this time that humanity can no longer imagine life without this device. But when did it start to turn into a smartphone?
Life without phones
Just some 200 years ago, people did not even know what telephones were. Previously, whistles, gongs, ringing bells and drumming were used to transmit messages over a distance.
By the way, in order to transmit the signal as far as possible, it was necessary to create intermediate points at which people were on duty. In this case, the sound came to the recipient through a chain. We all understand that this was a very long process. Of course, it was possible to solve this problem, for example, transmit information through water and metal. In this case, the signal would travel faster and fade out much later. But for some reason this was not done, at least everywhere.
What is a telephone
A telephone is a device for transmitting and receiving audio signals over a distance. Communication is established by dialing a specific number, and sound is transmitted using electrical signals. This is a general term that is used to refer to absolutely any type of phone.
It is important to note that the first telephones did not have dialing capabilities and only allowed communication between two devices connected by a single cable.

Here you can view the current Android version, firmware version, kernel version, build number, SE status for Android, Knox version (security system on Samsung devices), security software version (installed separately from smartphone updates), Android security level.
All this information will be useful to software developers and third-party applications.
Invention of the first telephone
We traditionally associate the appearance of the telephone with the name of the American inventor Alexander Bell. The famous researcher actually took a direct part in the development of the revolutionary apparatus. However, other people also played a vital role in the creation of the first telephone.

A year later, in 1861, the German physicist and inventor Johann Philipp Reis demonstrated his “mobile phone” at a meeting of scientists of the Physical Society. The device could transmit musical tones and human speech over wires. The device had a microphone of an original design, a power source (galvanic battery) and a speaker. Reis himself named the device he designed Telephon. Many sources from the time claim that the first message the physicist sent on his telephone was the phrase “Das Pferd frisst Keinen Gurkensalat” (“The horse does not eat cucumber salad”). The absurdity of this information made it possible to verify that the words were heard correctly, from which it follows that the transmitter was working as it should.
So, on February 14, 1876, Bell filed an application with the Washington Patent Office, and on March 7, 1876, the American received a patent. He called his device a “talking telegraph.” The Bell tube could alternately transmit and receive a signal. The American scientist’s telephone did not have a ringer; it was invented a little later, in 1878, by Thomas Watson. When someone called the subscriber, the telegraph began to whistle. The range of such a line did not exceed 500 meters.
Note that Alexander Bell was officially considered the inventor of the telephone for a long time. And only on June 11, 2002, the US Congress, in resolution No. 269, transferred this status to Antonio Meucci.
First phone call
In 1876, the first telephone conversation took place. Just 15 years earlier, serfdom had been abolished, and people were already making phone calls!
This call was probably associated with many technical difficulties, but one thing is certain: it was impossible to get the wrong number.
Alexander Bell called his assistant Watson, telling him: “Watson, Bell speaking! If you can hear me, go to the window and wave your hat.”
By the way, Thomas Edison also had a hand in the development of the telephone. It was he who came up with the idea of starting a conversation with “hello.”
"Hello" is nothing more than "hello". Hello is an international word, but in some countries people traditionally start conversations with a different greeting. For example, in Italy they say “Pronto”, which means “ready”.
In addition, Edison suggested using a microphone with carbon powder. Such microphones were installed virtually unchanged in home telephones with rotary dialers until the 1990s.
By the way! For all our readers there is now a 10% on any type of work .
The advent of mobile phones. The history of the modern smartphone
In 1969, world leaders in the telecommunications market began to think about improving the wired device. They wanted each subscriber to have their own number, which would be relevant not only in the country where it was registered, but also abroad. Stockholm Technical School graduate Esten Mäkitolo was one of the first to come up with such an idea. However, for the practical implementation of the Myakitolo concept, powerful technologies were required, which appeared only in the 1980s.
It was a handset weighing about 0.8 kg and measuring 22.5 x 12.5 x 3.75 cm. The battery allowed communication for as long as 35 minutes, but it took a little more than 10 hours to charge it. Of course, it cannot be compared with modern devices, but for that time it was a huge breakthrough.
Motorola DynaTAC - the first mobile phone
Motorola very quickly had competitors who began to release more and more advanced and intelligent models each time. So, over time, a calculator, alarm clock, calendar, camera and many other applications and functions appeared on the phone. In the 2000s. Phones with an operating system began to appear, which turned them into personal computers. Today, using a smartphone, you can do more than just call a friend or send a message. For him it is primitive. It can communicate with satellites, take large-scale pictures, play music, not to mention reading books, watching movies and multitasking.
