This is the beginning of all cell phone repairs. To be able to completely disassemble and reassemble any cell phone, you are now putting yourself in a position where you can single out the root cause of the issue, and thus move on to repair it. Many phones have different methods, but as you will see in our videos, many of them are also the same.
The first step to fixing a phone is diagnosing a phone. The best way to diagnose a phone is by understanding the phone's smallest components, and knowing what it's responsible for. This video explains the micro-components of the Galaxy S3, and what they do. For example, the front speaker is responsible for hearing the other person, whereas the microphone is responsible for them hearing you. So if someone walks in and complains that no one can hear them, we simply consider all of the potential issues that could be causing it, ie) the customer needs to speak louder, there is something covering the microphone or the microphone needs to be replaced. Then we logically rule out the ones that are unlikely.
This first lecture will involve the absolute basic disassembly of most current cell phones, and the proper diagnosis of the most common defects. Ie) Phone not turning on, People can't hear user, User can't hear others, Phone will not ring, etc.
The total disassembly of the popular LG G2. This is one of the more difficult courses. You should take particular note in how there are 2 "arms" that reach to connect to the main board. Consider carefully how the loud speaker is connected (via 2 prongs) and how the front speaker is connected (flex) cable.
The Galaxy Samsung Epic might even be a fun repair, especially if you're a mechanical engineer, considering the design and structure of the slide phone. This is our first slide phone model, and the slide phone requires a slide module that we will be taking a part. Please consider carefully the way it detaches and re-attaches.
The HTC One is a prime example of how some phones are attached with tremendous amounts of adhesive, rather than relying on many screws to be held together. Take a look at how this phone is very difficult to disassemble at first due to the tight adhesive, and how it must sometimes be reused to put back together.
The iPhone 4 is probably one of the most complicated repairs with all of the flex cables and screws and micro parts. In this lesson we will be showing you how to disassemble it, and help you understand what part is responsible for what feature. You can then use this knowledge to help diagnose and issue with a phone.
This section is incredibly important due to the fact that after becoming familiar with the disassembly of phones and also the structure of certain phones and how they are made, you MUST be able to start identifying each part AS YOU DISASSEMBLE it. This is crucial in repairing phones considering diagnosing the phones relies heavily on the knowledge of the function and responsibility of each part.
In this video we take apart the Samsung Epic and examine each part and explain what it does and is responsible for. We also examine the results of each part being absent.
In this video we will be taking apart the iPhone 5C and examining each part and why it's there. We will also be carefully examining what would happen if each part would be absent, and thus what defects could result if such parts were missing.
In this critical video, we will be taking apart the popular Samsung Galaxy S5 phone, and examine each micro part on the micro level (capacitors, transistors etc). Carefully pay attention as we now go into detail for the first time on the circuit level.
This is a video of an S3 being RE-ASSEMBLED after a LOCA adhesive screen repair. The Re-assembly is obviously just as important as the disassembly, considering this is where the replacement of faulty components takes place. Once again, practice makes perfect, eventually enabling the student to freely tear and and re-construct any cell phone, replacing faulty components on the way.
Really, most of cell phone repair is just process of elimination. Basically, we disassemble a phone down to its motherboard and its micro-components, and determine which part is responsible for the defect at hand. Then we replace that part. If it's a software issue, we do a master reset. If it's a firmware issue, then we re-install the firmware.
In this video, we make a primary example of how we diagnose a Samsung Galaxy Note 3 with a common issue--the user cannot here the other person speaking. You should be able to understand how we came to the conclusion that this part was the one that needed to be fixed.
The iPhones from the 4, 4s and 5, 5c, 5s are possibly some of the most complicated, but easiest phones for diagnosis. This is due to the fact that everything is attached together via flex cables that can simply snapped on and off. Each part, starting from the charging dock to the front speaker and even proximity sensor are all connected via small flex cables. This is an exellent example of how such diagnosis is performed and a good blue print for future diagnosis.
In this quiz you need to be able to determine what part(s) is(are) responsible for common issues on phones.
The iPhone 4 and 4S are potentially the most complicated and longest repairs. Luckily there is no heating necessary for replacing the screens due to the cheap price, but the multiple steps can prolong the repair time. In real life situations, we have utilized our grid sheet in order to facilitate the repairs at our stores. Please consider our examples of the use of the grid sheet in real life situations and consider the reduction in repair time. This full repair can usually be done with in 30 minutes with ample practice. You should be doing some practice as often as possible.
The iPhone 5C screen replacement is possible one of the easiest ones. However, due to the fact that there are some screws and even a metal plate that must be removed, the grid sheet is still necessary. This video has been shot also during live repairs. Consider, once again the live repair done in real time with the utilization of the grid sheet.
This is the disassembly of the LCD/Digitizer screen on the iPhone 5S only. Linked are outside sources on how to completely disassemble the phone, along with each respective micro-component.
This is yet another example of the same phone that we've covered during our disassembly videos of how you can use the grid sheet for just about any phone to reduce time and secure a safe repair.
One of the most popular and lucrative types of repairs in the industry is the GLASS and LCD separation on the Samsung phones. The screens cost about $5, but the repair is about $60-$80. It's very good profit.
Another example of the very popular and lucrative screen separation
One more example of how I disassembled a phone to expose each component and show what needs to be replaced for a proper repairs.
This is one of the most basic soldering techniques when it comes to repairing cell phones. Soldering is absolutely crucial when doing micro-component repairs. Most newer phones have flex cables to handle all of that, but the S3 and older models have to be soldered.
Learning what a transistor is, may not sound exactly like a very important subject, but you'll be amazed at what you can learn simply through transistors!
This is a pretty relevant and import and also EXCITING video of why exactly water damage DAMAGES phones. A must learn tutorial to understand the science behind it, and hot to prevent and even treat it.
Questions regarding the theoretical aspect of circuits.
The overall expenses that I've realized in my stores for repairs is around $400 to get started. With these repairs and parts, you can easily get started on Craigslist, as this business is now starting to become popular. This is also a great skill to have when getting hired at a cell phone store. This is a tremendous bonus to have if you or someone you know already owns a store
This is a rough guideline on how to get started in your own business of cell phone repairs as well. This is how I personally started, and it's taken me very far today. On average, I net profit about $8-10K/month. With the busiest 3 months right up ahead (Dec-Feb), you definitely want to take advantage of this course.
I have been a cell phone technician for 7 years now. I own 2 cell phone stores here in Atlanta, and I've been receiving great amounts of requests for cell phone repairs lately. I decided to give Udemy a shot, and give students the ability to learn how to repair phones, which can come in handy for engineering students in the future. So far, I've been pretty successful with my local students, as I have seen many of them opening up their own shops and making money as well. I hope this lecture comes in handy to students who wish to make their courses practical.
