Many iPhone XS Max users have the complaint that the Portrait Mode on their phones is not working. And it’s not a strange thing to see that questions like ‘Why does my iPhone XS Max Portrait Mode not working’ and ‘How to fix my iPhone XS Max Portrait Mode not working’ have been so frequently searched on Google. If you are one of them, this article will help you to solve this issue. Here REWA is going to tell you how to fix Portrait Mode not working on iPhone XS Max.

Usually, there are two different causes for Portrait Mode not working on iPhone XS Max. Software problems or hardware problems. Here we have some solutions for software problems.

Nota: Don’t use portrait mode in dark places or low light. Because portrait mode will not work in low light. And make sure that the distance between the phone and the subject is proper(neither too far nor too close). Keep at least 19 inches distance between the phone and the subject.

1. Restart your iPhone XS Max or camera app. 2. Upgrading iOS: Go to Set->General->Software Update. 3. Reset all settings: Go to Set->General->Reset-> Reset All Settings. 4. Restore your iPhone XS Max to Factory Settings(Factory Reset): Go to Settings->General->Reset-> Erase All Contents and Settings. Take a backup before resetting your iPhone to Factory Settings, since this action will erase all data from your device.

So, these are some methods to resolve the iPhone XS Max portrait mode not working issue. You can try them out. However, if nothing works, the possible situation is that the motherboard or the camera has been damaged. In this case, you need to have the damaged one replaced. Well, you can also follow our solution below.

The first thing we do is to check if the Portrait Mode is in a normal status. Open the camera app and swipe to portrait mode. We can see clearly that the background is not blurred. Which indicates that the wide-angle lens is working normally, while the telephoto lens is not working at all.

Take apart the phone and take out the motherboard. Run diode mode measurement of the Tele camera connector J4000. The measured value of Pin 25 is OL, which is abnormal. Which also indicates that Pin 25 relevant circuit has open-circuited(The circuit is formed by a zero-ohm resistor R4006, several capacitors and the camera power supply IC U3700). Since capacitors have nothing to do with the open-circuited condition. So the first thing we do is to check the zero-ohm resistor R4006. Run diode mode measurement of R4006. Judging by the measured value, R4006 has not open-circuited. We can confirm that the fault is probably related to U3700.

Try to replace with a new camera power supply IC. You need to separate the upper and the lower layer first. And then detach U3700. Continue to clean the bonding pad and solder a new camera power supply IC. Solder the two layers together later. Detailed steps go as follows:

Place the motherboard on the Heating Platform. This machine can quickly desolder & resolder iPhone XS Max double-layer motherboard. It offers heat evenly that can protect the motherboard from damage. With accurate temperature control and temperature adjustment, it is highly recommended for motherboard repair. Pick up the upper layer with tweezers once solder on the third space PCB has melted, and detach U3700 from the board with Pistola de aire caliente.

Apply solder to clean the bonding pad first. Then clean thoroughly with rosin soaked Solder Wick. Clean with PCB Cleaner afterwards. Get a new camera power supply IC in position and solder with Hot Air Gun. Next thing we need to do is to solder the two layers together. Clean the third space PCB with rosin soaked solder wick first, then reball the lower layer. Solidify the third space PCB with Paste Flux afterwards. Once done, apply some BGA Paste Flux to the third space PCB. Get the upper layer and the lower layer in position. Use the iPhone XS Max Motherboard Soldering/Desoldering Rework Station to solder the double-layer motherboard.

Once we have confirmed that the motherboard has been soldered successfully, we can assemble the phone and test. Warm tips: get the phone full assembled after confirmation of fault clearance. Get the motherboard and display assembly installed. Connect the battery and press the power button. The iPhone XS Max turns on normally. Open the camera app and swipe to Portrait Mode. We can see that the subject is being focused and the background is blurred. The Portrait mode not working on iPhone XS Max issue has been solved successfully.
