Tools play a huge role in determining the success of your cell phone repair project. It doesn’t matter if you’re a seasoned professional or a newbie in the industry—the rule of thumb is to get all the equipment in order before embarking on the job at hand. A good workstation is one that has a tool for every task.

  • Screwdrivers
  • Tweezers
  • Cutter
  • Lead sucker
  • Multimeter/tester
  • Soldering gun and solder
  • Brush

These are the most common tools that every technician should have; however, many other specialized ones might be required when working on specific phone models. In addition to buying all these pieces of equipment, you need to make sure that your workstation is organized. It can be quite frustrating when you’re in the middle of your work and you can’t find a screwdriver or cutter just because your desk is filled with a lot of unnecessary things.

2. Understand The Problem

Before you start dismantling the gadget, make sure you’ve reviewed the issue and have an idea of what might be faulty. Of course, it’s impossible to know where the real problem lies by just looking at the phone. However, narrowing down to a few possible factors will help save your precious time. Also, you’ll avoid messing up with the wrong parts while trying to determine the fault.

Smartphones are more sophisticated than the old handsets, which means the problem might not necessarily be hardware-related. For instance, fixing a parse error in Android smartphones requires a few tweaks of the software. Until you’re almost certain the phone’s software is working fine, don’t unscrew the device. If the device isn’t working at all, you can go ahead and open it up without going through all these procedures.

3. Keep The Data Secure

Before you start repairing the phone, make sure the data is safely stored to avoid deleting crucial information. In most cases, the data is more important than the gadget itself. Therefore, never delete anything without the owner’s consent. If it’s not possible to retrieve whatever is stored in the phone, let the client know before proceeding to the next steps.

Set up a folder on your computer or an external disk where you’ll be storing this data. As soon as the phone is ready to use, copy back the information and let the customer confirm that everything is okay. Remember to delete the files from your computer unless advised otherwise by the client.

Dismantling a cell phone can be very straightforward, provided you know what you’re doing. In the old days, it was quite difficult because there were all sorts of phones, such as sliders and flippers. Today, most handsets have a similar design with very few screws, mostly used to hold the inner parts in place. If this is your first time, make sure you know the process before starting. As such, you’ll avoid breaking some fragile parts or messing up with connectors.

5. Categorize The Screws For Easier Assembling

One of the most common mistakes made by beginners is forgetting to return all screws to their original spots. Remember, every screw is designed with specific thread pitch and width to fit in particular holes. Therefore, using the wrong screw will either mess up with the original threads printed in the hole or it will not be tight enough, which can be very risky.

So, how do you avoid such?  Well, the best way is to categorize screws with similar sizes to avoid confusion. For instance, all those used to hold the external case, if any, have equal thread pitches. The same goes for the smaller ones used for internal components. This trick will not only prevent simple mistakes as stated earlier but also save you time.

6. Make Sure You Have All The Spares Available

As earlier stated in the article, you need to figure out a possible fault even before you start dismantling the gadget.

However, don’t take everything apart before purchasing the replacement parts as you could misplace some vital components.

7. Take Care Of Fragile Parts

The LCD, for instance, is, perhaps, the most expensive part of a smartphone. It can also break quite easily if dropped on the floor or under any minimal external force.

The motherboard is another very crucial part of a phone or any electrical device for that matter. Since it has thousands of circuits printed on it, an electric short on one end could impair the whole gadget. Of course, these are quite basic for any professional out there.
