How to Fix or Replace a Shaky Rear Camera on iPhone 7

 Don't panic when iPhone black screen, iPhone camera out of focus, iPhone camera shakes! Today, phonefix takes iPhone 7 rear camera shake repair as an example to teach you how to fix or replace the iPhone rear camera shake problem.


Generally speaking, there are two reasons for iPhone 7 rear camera shake issue.

1. The rear camera is broken. You can replace the rear camera to fix it.

2. The rear camera circuit is faulty.

1. iPhone 7 rear camera replacement

1. Discharge your iPhone battery below 25%. Turn off your iPhone before beginning disassembly. Use a screwdriver to remove the two screws on the bottom of the iPhone. Use the hair dryer that holds the display to soften the adhesive.

2. Attach the suction cup to the lower half of the display assembly and insert the flat end of a spudger into the gap. Twist the spudger to widen the gap between the display and the rear case.

3. Pull the display assembly slightly away from the top edge of the phone to release the clips securing it to the back case.


4. Remove the lower connector bracket with tweezers. Remove the battery connector from the socket on the logic board. Disconnect the two lower display connectors by prying them straight out of the sockets on the logic board.

5. Remove the screws that secure the bracket to the front panel sensor assembly connector. Disconnect the front panel sensor assembly connector from its socket on the logic board. Remove the iPhone 7 display assembly.



6. Disconnect the rear camera crimper from the socket on the logic board. Remove the screws securing the rear camera bracket and bracket. Remove the rear camera and install the display and test.


How to solve the problem of rear camera shake caused by iPhone 7 rear camera circuit failure?

1. Confirm the damaged rear camera circuit. Use the opening kit to disassemble the iPhone 7 and remove the display assembly.

2. Remove the logic board and inspect the rear camera connector. Run diode mode to measure it. The measured value of pin 16 is 0, which is abnormal. The normal value is 600, so it is judged that the related circuit of pin 16 is shorted to ground.

3. Locate the faulty component. There are multiple filter capacitors on the circuit, so we can use the "rosin detection" method to locate the faulty component.

4. Remove the shielding sticker and visually inspect the logic board. The logic board is not deformed or damaged by water.

The circuit-related components were infused with rosin, and the DC supply voltage was set to 2.8V. Proceed to connect the test leads of the multimeter to the DC power source.

6. The black probe touches the GND connection on the logic board and the red probe touches pin 2 of the FL2502. Check whether the rail between pin 2 of FL2502 and J4501 is short-circuited. The rosin on the C2519 melted immediately. Judging from this, C2519 is damaged.

7. Clear the fault. Since the C2519 is a filter capacitor, we can simply remove it from the board. Connect the logic board to the PCB Holder. Remove the C219 with a heat gun.

Clean with PCB Cleaner afterwards. Diode mode measurements were made on the pads of the C2519. The measured value is 645, which is normal.

8. Assemble the phone and test it. Install the logic board and display assembly.

9. Connect the iPhone 7 battery and press the power button. The phone turns on normally. Tap the Camera app on the home screen. The rear camera stops shaking.

10. Switch to the front camera, the front camera works normally, switch back to the rear camera to take pictures. Check your phone. all the best.

How to quickly solve the trouble of Charging?

Image
 In today's fast-paced life, the frequency of use of devices such as mobile phones, tablets and smart watches is increasing. Many people often encounter the problem of insufficient power on their devices, especially when they need to travel or do important work. Slow charging of devices may be caused by insufficient power of the charger, faulty charging interface or the use of mismatched charging cables. These problems not only affect the efficiency of device use, but also increase the anxiety of users. There are two main ways to solve this problem: Choose a more powerful charger: A high-power charger can provide a faster charging experience and save waiting time. Make sure to use compatible charging cables and interfaces: Using mismatched charging devices may result in slower charging speeds. Using charging methods designed for your device can significantly improve charging efficiency. Considering these issues, the MECHANIC V-Power series of fast chargers provides users with solu...
