Since mobile phones are the current rage of this age, there are technicians in this field who are working since the advent of this invention. After so many years have passed the technicians have by now become expert as well as professionals. No matter how expert one is, mistakes can be committed by anybody. These errors may slow down the repair process, affect customer satisfaction, or damage the device further.

This detailed guide explains the most common mistakes made by technicians and how to avoid them. Every point is based on practical experience, honest observations, and real issues faced in repair shops. The aim is to help new and experienced technicians work in a more professional, safe, and accurate manner.

8 Common Mistakes Committed By Most Cell Phone Repair Technicians

1. Not repairing in the estimated time

This is one of the biggest problem with most technicians. There can be several reasons for the delay. It could be due to delay in troubleshooting the fault. Sometimes the fault in the handset is hard to detect and it may take a very long time to rectify the fault.

One other reason for the delay could be unavailability of spare parts. But delay due to mere laziness is a definite no-no. Repairing the phone and completing the job on time sends a strong message to the customers about how much particular as well as punctual you are.

Unnecessary delay due to poor time management creates a bad impression. Customers judge a technician not only by skills but also by punctuality. Completing repairs on time builds trust, shows commitment, and improves the technician’s reputation. It also increases repeat customers and referrals. Keeping a clear schedule, updating customers regularly, and planning inventory can prevent such delays.

Start by doing what’s necessary; then do what’s possible; and suddenly you are doing the impossible.

2. Not replacing all screws after reassembling

This is a very common and careless mistake. When a mobile phone is dismantled, some technicians are very careless and they just go about placing the screws on the workbench. Now while fixing the phone, they misplace the screws and when they reassemble the handset they fall short of these screws. Some technicians just leave these slots empty, while some of them use other unmatching screws which is bound to damage the original threads in the slots.

The best way to overcome this common mistake is to keep all the screws and other small parts in a small tray or a magnetic mat. This way you will be ensured that you have replaced all the parts and screws back in place and you have by no means left out anything that has to be replaced. Using different trays for different models of opened handsets will also help you to dismantle many handsets simultaneously.

3. Not Asking the Customer for Correct Problem Details

Many technicians skip an important step—understanding the issue directly from the customer. Many technicians do not ask the customer about the reason or cause for the fault in their phone. Instead if the customer is asked about the problem you can straight away know the exact problem and start working on it thus saving your precious time. If the technician asks the right questions, the root cause becomes clear.

Also make it a point to ask the customer about the history of the handset and whether he had already given it to someone else for repairs before for this same fault or some other fault. This way you will know if the handset was already opened before or not.

Proper communication avoids misunderstandings and ensures transparent service.

6. Not repairing in a professional manner

A technician’s work should always look clean, organized, and professional. Customers can instantly differentiate between good-quality work and careless work. Many technicians are very careless while repairing a handset. The job that they do is shoddy and also looks awful if watched closely. All procedures and techniques should be carried out in a professional manner.

Soldering work done by many technicians is very amateurish. The solder flux applied all over should be cleaned up after the work is completed. It is utmost important that a professional technician does a clean job that gets a feeling whether it is factory fitted or if it is fixed at a service center.

A technician should always aim to give a result that looks like the phone was repaired in an official service center. This builds a strong reputation and shows genuine expertise.

7. Not following the fault finding steps

As the handset comes in for repairs, many technicians do not go step by step in fault finding. Instead they just go about by dismantling the phone and carrying out the hardware rectification.

A proper repair process generally includes:

1. Inspecting the phone externally
2. Checking battery condition
3. Testing with another charger or cable
4. Checking the charging port or buttons
5. Testing the display
6. Verifying software issues
7. Only then opening the handset

Skipping these steps can lead to wrong diagnosis and unnecessary repairs. A structured approach saves time and helps identify the correct fault quickly. It is utmost important that repair work of an electronic gadget should go as per the professional repair methods.

8. Unnecessarily working on the motherboard and chips

Some technicians unnecessarily start working on the motherboard without any reason. They fiddle with the motherboard as well as the chips applying heat or just reflowing. Working on the motherboard should be the last step while fixing any hardware fault.

Heating, reflowing, and touching components on the motherboard should be the last option, not the first.
