‘while taking a picture from my iPhone 7 Camera, I can see picture shaking as I hold it straight however when I tilt it sideways, the picture appears stable. Can someone help me solve this issue?’
One user from Apple Support reported his problem and asked for help.
Many iPhone 7 users feedback that their rear cameras shake when taking a picture. However, the front camera works normally. They searched online for solution. Nothing has changed after updated to the newest iOS Version.
Some people found a solution. A magnet can prevent iPhone 7 rear camera from shaking. They attach a magnet to the camera holder ring. The rear camera stops shaking at once. But when they move the magnet away, the rear camera starts to shake immediately. There is a coil for focusing inside the rear camera. The magnet can prevent the coil from shaking by influencing the magnetic field.
Why iPhone 7 rear camera shakes and how to fix?
There are two reasons for the shaking problem of iPhone 7 rear camera.
1. The rear camera is broken. Need to change rear camera.
2. The rear camera circuit has malfunctioned.
Today, our case is about the iPhone 7 rear camera shaking problem, which was caused by malfunction of the rear camera circuit.
Step 1 Confirm the damaged rear camera circuit
At first, take apart the phone and remove the display assembly. Then take out the logic board. The first thing we do is to check the rear camera connector J4501. Run diode mode measurement of J4501. The measured value of Pin 16 is 0, which is abnormal. The normal value should be 600, judging by this, relevant circuits of Pin 16 have shorted to ground.
Step 2 Locate the faulty component
Since there are multiple filter capacitors on the circuit, we can locate the faulty component with ‘rosin detecting’ method.
Tear off the shielding sticker and run cosmetic inspection of the logic board. The logic board is not deformed or water damaged.
First, smoke rosin on relevant components of the circuit. Then, set voltage of the DC Power Supply to 2.8V. Continue to connect test leads of the Multimeter to the DC power supply. With the black probe contacting a GND connection on the logic board, contact the red probe to Pin 2 of FL2502. Check whether the rail between Pin 2 of FL2502 and J4501 has shorted. Rosin on C2519 melts immediately. Judging by this, C2519 is damaged.
Step 3 Clear fault
Since C2519 is a filter capacitor, we can simply detach it from the board. Attach the logic board to PCB Holder. Remove C219 with Hot Air Gun. Clean with PCB Cleaner afterward. Run diode mode measurement of the bonding pad of C2519. The measured value is 645, which is normal.
Step 4 Assemble the phone and test
Get the logic board and display assembly installed. Connect the battery and press the power button. The phone turns on normally. Tap on the camera app on the home screen. The rear camera stops shaking. Switch to the front camera and the front camera works normally. Switch back to the rear camera and take a picture. Check the phone taken. Nothing goes wrong.
Warm tips: get the phone full assembled after confirmation of fault clearance.
