| 14 | Proximity-sensor Test（100mA) | Use the palm to cover the light sensor hole, and the screen will turn green from black. If the interface shows “PASS” and jumps to the next test, the function is sound; |
| 15 | Proximity-sensor Test（150mA) | Use the palm to cover the light sensor hole, and the screen will turn green from black. If the interface shows “PASS” and jumps to the next test, the function is sound; |
| 16 | Keypad Test | Press the power key and volume key one by one. If keys can be pressed normally and the interface jumps to the next test, the function is sound; |
| 17 | Fingerprint Auto Test | If the interface shows “PASS” and jumps to the next test, the function is sound; |
| 18 | Media test | Click the “20-4K（-3db)signal” to test the sound of the media function for 5s. If there is no silence, weak sound, noises, and breaking sound, the interface shows “PASS” and jumps to the next test, the function is sound; |
| 19 | Call test | If the phone has been installed with the operator's SIM card, dial the corresponding operator's phone number. If no card is installed, call the 112 to test (Calling the Operator is recommended). If the call can be performed normally and the receiver is without noises or weak sounds, the function is sound; |
| 20 | NFC Test | Close the phone of the rear camera area to the NFC card reader. If the signal light of the card reader changes from red to green with “Beep” sound, the interface shows “PASS” and jumps to the next test, the function is sound; |
After the above 20 items are tested, they will prompt to the test result interface. If the test PASS, project will show “√”; If the test FAIL, project will show “×” as shown below.
8. General Cautions
1. Calibration is required after maintenance if there is any replacement of mainboard, display or fingerprint module.
2. After assembly, calibration must be performed before functional test to ensure the proper usage;
3. Some sensory test items may require artificial judgments such as LCD test, vibration test, pre-test, post-test, flash test, echo test, audio test, and call test. Therefore, test judgment requirements must be followed when operate function tests.
4. It is not allowed to press the return key to judge the result in advance if the test items have not been tested.
