5 Basic Self-checking Steps After Mobile Phone Repair

In this article, we share 5 basic self-checking steps you should perform after sending your mobile phone for repair in Kuala Lumpur or Selangor.

When our mobile phone has an incurable problem, we believe that most people will choose to send their device to the mobile phone repair shop to handle the faulty machine. After getting the repaired mobile phone, we also believe that many people will only look at whether the previous problem is solved or not, even if they don’t even look at it and leave it alone. But this is not a good habit, isn’t it?

If you are careless or you feel too troublesome, after repairing, you will not see if the mobile phone is completely repaired and go home. However, if the same fault is not solved, or a new problem arises, it will inevitably run another round to mobile repair shop to deal with it. Spend more money. The following is to tell everyone how to self-test when we get the repaired mobile phone, thus reducing some unnecessary situations.

No matter any fault occurs in any type of mobile phone, when the service personnel hand the repaired mobile phone to you, it is necessary to conduct a comprehensive check on the mobile phone function. In particular, the repaired fault is repeatedly tested and confirmed. Payment can be made without errors. The self-test method can be described by a set of pipelines, which respectively check the five functions of the button, call, setting, charging and touch screen of the mobile phone. The simple five steps solve the problem for the user of the mobile phone.

Repairing the mobile phone, I believe that everyone will not be unfamiliar. As a daily necessities, mobile phones have experienced such failures, and it is inevitable that they will be repaired. In the past, many people have suffered a lot of inexperienced losses in repairing mobile phones. If you can use the five-step self-test to solve the trouble of “two into the palace” after maintenance, we believe this method is still very practical.

1. Button function check

In the process of repairing the mobile phone, the mobile phone will inevitably undergo the process of disassembly. The button is a place that is easy to ignore when installed. Its fault is often caused by common mistakes such as placing and resetting. Of course, there may be problems on the line. And all we have to do is simply find them.

When we get the repaired phone, the first thing to check is the button, which is the number, power switch, HOME and volume adjustment keys. Normally, we only need to check whether the mechanical function of the button is normal. Press each button to try it, and see if it can be bounced or reset after pressing. If the mechanical function is not normal, you need to reassemble.

The mechanical function is normal, and then check whether the screen can display the corresponding characters or functions after each button is pressed. If the display is not normal, you need to check if there is a problem during the phone assembly process. Of course, if you can directly tell the maintenance staff about the relative accuracy and professional terms like “catch, misplacement, disconnection”, I believe that the other party will not look at you again.

All the buttons on the phone should be tested. If all the tests are completed, then the button function is normal, and then the next function is checked.

2. Call function check

The call function is a mandatory item. The reason is not to mention. If the call function is not normal, what is the meaning of the phone? The purpose of the call function check is to test whether there is a problem with the microphone (MIC), the receiver (handset), the speaker, the vibration motor, and the SIM card.

We have to make a call and the two parties make a call. If there is no problem with the call, there is no problem with the button input, microphone, and handset. However, if you find a signal abnormality during the call or if the other party listens to your voice is too small, you need to check with the professional maintenance personnel again to check the SIM card and signal circuit. This test is often done by the maintenance personnel in coordination with the owner, so the user does not have to worry about trouble or face, and can make a phone call to a friend.

3. Charging function check

After all, the disassembly and disassembly of the mobile phone is manual and manual. It is inevitable that some mistakes will occur. In order to prevent the hard injury from falling on its own head, when we get the repaired mobile phone, we need to check its charging function.

I have encountered such a problem before, after the Samsung phone repair, I found that the charging function often has some abnormalities. For example, after the power is connected, the mobile phone does not respond, and even abnormal overheating may occur. Most smartphones have battery protection. If this happens, your phone is likely to have a problem with the charging circuit.

When taking over the repaired mobile phone, we should not be bothered. Please use the original charger for about 10 minutes to see if the charging function is normal. If it can’t be charged, or if it is abnormal, it means the charger, battery, battery contact. There may be problems with the mobile phone charging circuit.

4. Touch screen function check

Most smartphones now use a touch screen, which is divided into resistive and capacitive. Needless to say, the screen of this material has basically been eliminated. Only a few tablets and e-book products use this screen, so screen correction and other problems will not appear here.

For the capacitive touch screen mobile phone, the test method is very simple, and the user only needs to gently touch and slide to see whether it is good or bad. For example, touch any icon on the home screen icon and hold it down until it starts to shake, then press and hold the image to drag across the screen. If you can’t drag it when you drag it to a location, it usually means There is a problem with this part of the touch screen.

5. Accessibility check

The auxiliary function check is to find out whether the mobile phone works normally through common functions, such as Bluetooth, WLAN (ie wireless function), memory card and other functions.

Bluetooth: If the phone supports Bluetooth, if possible, we can pair it with the Bluetooth headset to test if the function is normal.

WLAN wireless network: Turn on the WLAN function and check if you can browse the web. If you can access the Internet, this means that the WLAN function is normal. However, it should be noted here that the connection time and network speed of the WLAN need to be noted. If the connection time is too long or the network speed is abnormal, further testing is required. At this point, we need to test the phone to the current maintenance personnel.

Memory Card: Open or play the file or video in the memory card. If it is turned on normally or the video is playing normally, the memory card function is normal.

Check the corresponding functions of the mobile phone by checking the functions of the menu, and try not to wait until you get home to find the problem.


At this point, the basic function check is finished. For the fault part that has been repaired, it is important to test these five steps. If  the display screen is replaced, then it is necessary to repeatedly check whether the screen display is normal. If the mobile phone case is replaced, it is necessary to focus on whether the button is accurately worked.

In short, the simple five steps can basically cover the self-test procedure after most Android or iPhone repair. Users only need to take the test station for 5-8 minutes, you can avoid coming back the second round for maintenance, so why not?
