Speaking for mobile gadgets the situation is completely different. Telephone – this is a standard one-plane thing. Our advice is to take and disassemble several phones placed in a case of the same type - mono block. You will simply see that this simple design is made according to an identical template. Cell phones themselves are made by robots at manufacturing plants, and specialists only change the appearance and modify the functions. But in general - the same thing.
- Information sent from a mobile phone is vulnerable.
- Information stored on mobile phones is vulnerable.
- People are designed to provide information about their location.

Mobile networks are private networks operated by commercial entities, which may be under the exclusive control of the government. The commercial facility has virtually unlimited access to customer information and communications, as well as the ability to intercept calls, text messages, and track the location of each device. Operating systems, used on themselves mobile devices ah, are specially designed or customized by phone manufacturers according to the specifications of various service providers and for use in own networks these companies. The number of features available on mobile phones has increased over the past few years. Modern mobile phones are essentially Internet-connected portable mini-computers with mobile phone functions. To determine which aspects of your communications are most in need of protection, it can help to ask yourself a few questions: What is the content of your calls and text messages?
Previously, there was a period when there was a fundamental shortage of spare parts for repairs. The spare parts for telephones themselves were extremely difficult to find, even by visiting all the large radio stores. Now the situation has changed to a large extent.

Who do you communicate with and when? Information is vulnerable in many ways. Each mobile phone provider has full access to all text and voice messages sent through its network. Phone providers in most countries are legally required to keep records of all communications. In some countries, service providers are under the monopoly control of the government. Voice and text communications can also be used by third parties in the vicinity of a mobile phone using inexpensive equipment. Information is vulnerable in the phones of the sender and recipient Example: mobile phones can store all kinds of data: call history, text messages, sent and received, address book, photos, video clips, text files. This data may reveal your network and personal information about you and your colleagues. Providing this information is difficult, even - on some phones - impossible. Modern mobile phones are pocket computers. With more features comes higher risk. In addition, phones that connect to the Internet are also susceptible to the insecurity of computers and the Internet. People give out information about their location. Within normal operation Each mobile phone automatically and regularly informs the service provider telephone communication where he is at this moment.
- Information is vulnerable when sent from a mobile phone.

If you understand the field of electronics, this will only help you. It should be emphasized that the creator of the course “
"revealed all the secrets and difficulties for a novice specialist. If you look at it, it's real the right approach in providing training material. Without the initial basics, it’s not realistic to count on anything else.
Borna: Of course: it's a telephone! You call someone, you talk to them, they talk. You can do this wherever you are. These days you can do many things with these devices. But let's talk about some risks and precautions, especially if you think someone might be interested in finding who you're communicating with and what you're saying. The following sections discuss a number of simple steps steps you can take to reduce the likelihood of security risks arising from the use of mobile devices.
How to repair a mobile phone?
You may have already heard about the video course . This course appeared on the Internet quite recently and, to be honest, the topic that the author talks about is very interesting to me.
Mobility and vulnerability of information
Communication histories, textual and voice messages, address books, calendar, photos and many others useful features phones can suffer greatly if the phone or data is lost or stolen. It is very important to know the information that is stored, both actively and passively, on your mobile phone.
Information stored on a phone can affect the person using the phone, as well as everyone in their address book, inbox, photo album, etc. Mobile phones that connect to the Internet are also subject to the risks and vulnerabilities associated with the Internet and computers, as discussed in our other tactics guides regarding information security, anonymity, information retrieval, loss, theft and interception.
How can this video course be useful?
If you are interested in cell phone repair, you have probably encountered a lack of knowledge and experience in this field. Not everyone has the opportunity to attend in-person training courses on cell phone repair, and their cost is quite high.
But today the situation is changing, and you can learn how to repair cell phones yourself. For those who have been familiar with electronics for several days, mastering the video course is not difficult. There would be time and desire.
To mitigate some of these security risks, users should be aware of their phone's potential for insecurity as well as its settings. Once you know what might be possible problems, you can establish guarantees and take preventive measures.
Borna: One of the advantages of the mobile phone is that they don't know where our meetings are if we organize them using our mobile phones by going to the bazaar instead regular phones, where they can overhear us when we speak.

Some important points about cell phone repair.
When doing paid repairs it is extremely important arrange the supply of spare parts and parts for repair. I repeat, this is very important!
Borna: Someone said they bribe technicians over the phone to get information. He also helped me buy one of those prepaid little chips you put in your phone. Delete posts frequently phone call, messages, recordings address book, photographs, etc.
If you use your phone to browse the Internet, follow safe methods, similar to the ones you use when you are on your computer. Connect your phone to your computer only if you are sure it is malicious. Our guide How to protect your computer from malware and hackers. They may contain viruses, malware or spyware. Observe the behavior and operation of your phone. Watch out for unknown programs and running processes, strange messages and unstable operation.
Let's look at an example from life. Personal experience.
While doing paid repairs of electronics (not cell phones), I ran into a problem. The problem was that there were no spare parts or parts on hand to replace faulty ones. Drive to the city 150 km away. because of some kind of microcircuit it was expensive. Moreover, the electronics that were brought in for repair were not of the same type. What does heterogeneous mean? This means that today they brought a car radio, tomorrow a TV, and maybe a thermostat. It is clear that in this case it is extremely unprofitable to buy in reserve the necessary parts for repairs. Especially if the number of orders is small. It is extremely difficult to use parts from the storeroom and thereby recoup the money spent on them.
If you don't know or don't use certain features and apps on your phone, disable or uninstall them if you can. A mobile phone is essentially like a computer and thus shares the vulnerabilities and uncertainties that affect computers and the Internet. Tracy said the device made a loud noise and got very hot in one corner when she made the call. Then her screen cracked and bent her ear. She wanted to know what to do.
Purchasing spare parts
The phone was clearly dangerous - and letting them touch it again probably wouldn't help. Nobody has the right to repair anything. Without intelligence, do they talk about how these products are made and the components inside them, as well as the tools and sometimes spare parts they offer? But Tracy's experience makes me wonder if the entire renovation industry is consumer electronics farce. They started with batteries that cannot be removed and continue with hidden screws.
The situation is different for mobile phones. . A mobile phone is a product of the same type. Just for fun, try to disassemble 2 - 3 phones in a candy bar case. You will see that the design has specific pattern. Mobile phones are churned out by robots at the factory, and the developers only change appearance and some functions. Otherwise, everything is the same.
Even water resistance flies before repair work. Soon, when you open that phone, you can probably kiss any real waterproofing you could kiss goodbye. This, for Gordon-Byrne, is a positive. "Most repairs are actually easier than people expect," she told me, adding that many repairs aren't repairs at all—they're just replacing parts. If the board fails, the repair shop pushes it out and the slides are a new board.
“I agree that there is a shift in manufacturing that tends to use more adhesives and more integrated parts,” Gordon-Byrne said. Today's phones have almost no moving parts. C. some of their own repair services.
Also there are certain running models. There are the most common faults with these models. Repair similar devices easier. All radio mechanics know this.
Those who repair cell phones sometimes buy 3-5 displays, cables, connectors, connectors for future use, so that the required part is always at hand! How do they know this? Of course from my experience.
A few years earlier, there was a severe shortage of cell phone replacement parts. Cell phone parts were difficult to find even in major radio markets. But now the situation has changed dramatically. In almost any major city you can find stores specializing in the sale of spare parts for cell phones: displays, cables, connectors, and more. A good example The Profi chain of stores and the Siriust.ru website itself can serve. Such stores give discounts regular customers and workshop owners!
What is also encouraging is that prices for spare parts for cell phones have become affordable and, in most cases, cell phone repairs become economically justifiable.
Special equipment for cell phone repair and consumables also became available: fluxes, solders, solder pastes, stencils for BGA and much more that is not always needed during the repair process.
I believe that this situation is a huge plus, since the availability of spare parts for repairs is one of the most important components of success!
Will a complete “newbie” in electronics be able to master mobile phone repair? I just want to say: “No!”, or “Rather no than yes.” In any case, it is important to know basic principles . Naturally, radio electronics also has its own basic principles that even the most stupid master needs to know.
Knowledge in electronics is highly desirable. It is also worth noting that the author of the course "Effective do-it-yourself cell phone repair" I devoted the first few video lessons of my course to basic electronics components and reading circuit diagrams. In my opinion, this is a very correct approach to presenting the material. Without knowing the basics, it will be difficult to count on anything more.
Therefore, you can quickly master mobile phone repair using this course without basic knowledge, with a “jerk”, it will most likely not succeed. But there is also no point in diving deeply into the circuitry of cell phones. Most faults are of the same type and do not require the use of complex or special knowledge in circuit design.
I don’t know how video decoding occurs in a DVD player processor and I am only superficially familiar with the circuitry of these devices, but this does not stop me from troubleshooting typical DVD player problems. The minimum that may be required when mastering the course materials is experience. An interest in radio electronics and even a little knowledge in this topic is also desirable.
Practice, practice and more practice!
Practice is very important in repairing electronics, especially things like cell phones. The experience that is gained in the process of troubleshooting is "gold asset", which will work for you in the future.
Beginners, as a rule, encounter difficulties at first; it seems to them that the repair time for one device is very long, and emergency situations arise. But all masters go this way. How more devices will pass through your hands, the more confident you will feel when repairing new, complex devices. Therefore, if you want to get serious about repairing mobile phones, then think about where to get devices on which you can at least practice, “get your teeth into”, learn how to competently and accurately disassemble/assemble a phone, solder a cable, connector, microphone, etc.
Attention to detail.
A cell phone is a very technological device and should be treated with respect. When renovating, it is important to pay attention to detail. For example, if you carelessly select a replacement display or board, you can throw money away. I bought a display, replaced the broken one in my phone, but it doesn’t work?! What the...? Ah, the revision is wrong. Exactly. You'll have to buy another one.
A banal and stupid situation. And all because of inattention to those very little things! In a cell phone, even a loose bolt can cause it to not work. And that's a fact.
And for a snack. How much can you earn?
Let's not "hover in the clouds" and build "castles in the air", but just roughly estimate how much you can earn by fixing, for example, 10 cell phones with simple faults? The average cost of repair even for the most ordinary and minor fault is 500 rubles. For 10 phones we will receive 5,000 rubles.
Those who repair mobile phones professionally and have an established flow of clients receive income that can reach 200,000 - 300,000 rubles. per month. At the same time, it is necessary to repair about 200 devices per month. 1 master can easily earn this amount.
Commendable! But for a beginner, create a business on your own and earn 200,000 - 300,000 rubles. per month? Sorry, but this is fantastic. Although there is one thing...
I have already said that I myself occasionally do paid repairs and for me even 5,000 - 10,000 rubles. cell phone repair would be a good start. Yes 200,000 - 300,000 rub. per month is cool, but you need to calculate your strength correctly. At the same time, it is not necessary to open your own service center or become an entrepreneur. To get started, you can repair cell phones at home in free time. Many radio amateurs engage in paid repairs. This is additional income and a favorite thing to do. And that's great!
Those who do not stop there discover additional service centers and hire a worker. Most often, they themselves teach the basics, since repairing cellular phones in technical schools and universities is easy. don't teach. Alas, but this is a fact.
Do not forget that in any business the so-called “20/80 principle” applies. It is also called Pareto's law. The bottom line is that out of 100% of beginners, about 20% achieve success. The rest either quit or start doing something else. This is, of course, a rule of thumb that doesn't always apply, but you need to understand that you have the right to fail. You can learn to repair cell phones and become a master, but not everyone can run a repair business.
