1.Guidance

The purpose of this document is only to guide OPPO technicians to carry out maintenance service to OPPO products. The content shall be keep in confidential, only avail be able to OPPO authorized service centers, and cannot be provided to third parties without authorization. Please follow the regulations and the guidance for maintenance service. For any problems, please contact China HQ in time.

1.1 Warnings

1. Care must be taken on installation in vehicles fitted with electronic engine management systems and ABS (Anti–skid Braking Systems). Under certain fault conditions, emitted RF energy can affect their operation. If necessary, consult the vehicle dealer/manufacturer to determine the immunity of vehicle electronic systems to RF energy.
2. Phones must not be operated in areas likely to contain potentially explosive atmospheres, e.g. petrol stations (service stations), blasting areas etc.
3. Operation of any radio transmitting equipment, including cellular telephones, may interfere with the functionality of inadequately protected medical devices. Consult a physician or the manufacturer of the medical device if you have any questions. Other electronic equipment may also be subject to interference

1.2 Cautions

1. Repair services and calibrations must be undertaken by qualified personnel only.
2. Use only approved components as specified in the parts list.
3. Ensure all components, modules screws and insulators are correctly re-fitted after servicing and alignment.
4. Electrostatic discharge is the main cause of damage to sensitive components of electronic products. Service centers must operate in accordance with OPPO's requirements for ESD protection. Ensure all work is carried out at an ESD workstation and that an ESD wristband is worn.

2.General Repair Information

1.Ensure all work is carried out at an ESD workstation and that an ESD wristband is worn before starting maintenance.
2.Wear ESD gloves to avoid oil stains and fingerprints.
3.Use protective films to protect the display, camera, camera lens to prevent dust and scratches.
4.Use a clean cloth, ESD brush and alcohol (Concentration above 95%) for appearance cleaning. Do not use other items (such as an eraser) for cleaning to prevent the protective layer from being scratched, which may lead to oxidation and corrosion.
5.Faulty welded mechanical parts (except shield cover and shield frame parts) can only be replaced and not repairable.
6.Use accessories provided by OPPO.
7.Check the contacts or solder joints of devices that may cause simple faults (e.g. soldered interfaces or switches). Re-weld if necessary (only for service centers where lead-free soldering is available) and clean the flux remaining after soldering.
8.Use the equipment provided by OPPO to test the phone (e.g. When the charging function of the device is abnormal, do use the original OPPO adapter to test to ensure the accuracy of the test results).
9.Fill in the fault phenomenon code and fault reason code according to the actual situation, and accurately enter the replacement material code in the CRM system.

According to the prompt "please place the yellow rubber ", put the yellow rubber on the fingerprint spot area (the groove is facing down), and click "NEXT" until it prompts " please place the black rubber".	3.According to the prompt "please place the black rubber head", put the black rubber on the fingerprint spot area (the groove is facing down), click "NEXT" until the "please place the yellow stripe rubber " prompts to remove the black rubber ;
Icon
Operation	4. According to the prompt “Please place the yellow- striped rubber”, put the yellow stripe rubber (striped down) in the spot area, click “NEXT”;	5. Prompt “Test completed, please reboot”, remove the yellow stripe rubber and complete the test; If the prompt is fail, check if there is a problem with the fingerprint module installation and recalibrate the test.	Note: The stripe direction of the yellow stripe rubber should follow the long side of the phone. After the calibration is completed, the phone needs to be restarted
Icon

6.3 Dual Camera Calibration

6.3.1 Calibration Scenario

1. When the portrait mode is poorly blurred, the after-sales service center needs to calibrate the phone.
2. All devices must be calibrated after the phone has disassembled, or the portrait mode will be poorly blurred.

6.3.2 Calibration Tool

After-sales calibration Chart,
As shown in Figure 6.3.2-1:

6.3.3 Calibration Method

1. 1. Please align the yellow box with the edge of the chart, and then take a Photo. Then, do not operate the phone when the phone enters the computing interface until it displays “Pass” with the calibration completed.

Precautions：
1. If it shows “Fail 69” during calibration, the lens is too far from the chart;
2. If it shows “Fail 70” during calibration, the lens is not parallel to the chart;
3. If it shows “Fail 68” during calibration, the lens is too close from the chart;
