Your phone's camera may be crooked, and another raffle project was born?

Two days ago, a up master of station B, "Gray Ke Said", made a video, and came up to directly enlarge the move:

Huawei's new flagship Mate 60 Pro, the camera turned out to be crooked, and the after-sales service also said that this is a normal phenomenon!

The main camera and telephoto lenses are not aligned, the image is skewed when switching lenses, and he has tested the same problem with several machines in a row.

In the comment area, some friends also stood up one after another, supporting the statement of the UP master with their own tests.

After seeing this video, we also tried the Mate60 Pro and RS in our hands...

It's really crooked.

It seems that even a super enterprise can't avoid this kind of low-level mistake...

But just when everyone is complaining about Huawei, Xiao Heipang, who bought the Mate 60 Pro at his own expense, may be a little unwilling, and suddenly there is a soul torture:

Is it possible that everyone's lenses are crooked? This isn't a bug, it's a feature?

Originally, Tony didn't believe it, until we actually tested the two or three phones we had at hand...

That's it, it doesn't matter, just grab a MIX Fold 3.

Xiaomi, do you have it too?

Since among the three or four mobile phones that we grabbed at random, we found two examples of "crooked lenses".

Now everyone has to admit that this kind of "low-level error" may really be widespread.

In order to verify this, Tony asked Huami OV and Apple, as well as a total of 19 models of their sub-brands, a total of 22 mobile phones for a round of testing.

We found two of the Huawei Mate 60 Pro and a similar Mate 60 RS, three for the Oppo Find X5 Pro, and two for the Xiaomi Mi MIX Fold 3.

To make it easy to see if the cameras are aligned, we put a straight tape measure on the poster wall in our office, just perpendicular to a yellow wire on the floor.

The whole test goes something like this: the phone is fixed on a tripod about three meters from the wall, and each camera is used to take a photo.

Finally, we zoom in and out to see if the yellow tape measure overlaps multiple photos from the same phone.

Theoretically, a normal phone should go through this step.

For example, the iPhones we tested, the Vivo X90 Pro+, the Xiaomi Mi 14 Pro, and the Oppo Find X6 Pro, all of which capture images that overlap almost perfectly.

But in fact, there are quite a lot of mobile phones that can't pass...

Of the devices we tested, 4 Huawei phones were unfortunately wiped out.

Xiaomi, OPPO, and vivo are all Schrödinger's performances, some of which fit tightly, and some of which are crooked out of the sky.

Of the 22 devices tested, 14 had crooked cameras, and 6 of them were very crooked.

Examples of minor deviations and severe deviations

To be honest, if it weren't for watching the video of that up master, Tony wouldn't have realized that there was a problem with so many phones that he had used for so long.

But now look at the slight deflection that will occur every time you switch cameras, how awkward it looks...

And we also found that there is also a big difference in the degree of crookedness of the same model of machine.

Two MIX Fold 3s, one not crooked at all and one crooked;

The degree of crookedness is also different between the two Mate60 Pro/RS phones.

This is where things get complicated.

Similar photo skew bias seems to be not only common, but also in the same mobile phone, can there be individual differences?

Our friends in the hardware department discussed it, and there are about three possibilities for this:

The first one is the easiest to understand, when the mobile phone assembly factory installs the camera, it is crooked;

The other is also crooked, but the pot is not in the mobile phone assembly factory, but when the camera module is encapsulated, the sensor (commonly known as the "bottom") is crooked;

The last one is a software configuration issue, and the phone's optical image stabilization system may be faulty.

The first two problems are not easy to troubleshoot under the conditions of our editorial department, so let's start with the last possibility-the stabilization system to see if it is pulling the camera sensor crooked.

Here's the thing:

Optical image stabilization on mobile phones is essentially an optical image stabilization system that controls the translation and rotation of sensors and lenses according to the frequency and direction of the shaking of the mobile phone itself to counteract the shaking of the mobile phone.

If the OIS system is misconfigured, the sensor may be "rotated" to an unhorizontal state in everyday situations.

But we soon realized that this theory was wrong, because the skew that appears on the Redmi K60 Ultra cannot be explained by OIS.

According to our understanding, the optical image stabilization of the main camera of this mobile phone is two-axis, and you can only pan the lens of the main camera up and down, left and right, and cannot rotate the sensor.

And only the main camera has this entry-level OIS, the telephoto does not.

In the case that OIS is not capable of making mistakes, its main camera and wide-angle images still show noticeable angular deviations.

This shows that OIS is certainly not the only culprit of deviation.

After further research, we found that most of the OIS stabilization on the current phone is the same as on the K60 Ultra, which is two-axis, and has no ability to skew the sensor at all.

If you want to get the sensor skewed, you need at least an advanced OIS greater than or equal to three axes.

The only device equipped with this advanced stabilization is the Oppo Find X5 Pro, and the other camera skews must have nothing to do with OIS.

So we started looking for ways to move forward again.

First of all, it is unlikely that the "bottom" was crooked when the mobile phone sensor was packaged.

Because the mobile phone sensor is essentially a chip, the chip manufacturing plant is not a pheasant workshop, even if there is a deviation in the packaging process, it should be the same model of every machine, the angle of deflection is the same.

In other words, even if it is biased, it must be biased and precise, and it is impossible to be biased differently for each unit as it is now.

This kind of "irregular" skew, on the contrary, is more likely to overturn during the assembly process.

But when it comes to this, a colleague who has opened a mobile phone after-sales shop has something to say:

You must not have assembled a mobile phone (indeed have not installed it), the camera inside the mobile phone is fixed by several screws, the holes on the motherboard are almost seamless, and there will be a roll cage on the outside for limiting.

Xiaomi 13U

In order to convince us, he opened several disassembly videos from the Internet on the spot for us to see.

As a result, it turned out that there was a problem.

There are two ways to install multiple cameras – in the form of a roll cage to be exact!

The first is to integrate the three cameras into the same metal roll cage, and then attach the entire metal frame to the phone.

Similar all-in-one roll cages, mainly the Xiaomi digital flagship series, as well as the iPhone in use.

Their cameras are so close.

iPhone 15 Pro Max

Since all cameras share a roll cage, there is no rotational deviation between them, as it is not possible to rotate a single camera at all during final assembly.

This is also proven by our tests, and the cameras that are not crooked are mostly Xiaomi flagships and iPhones.

The second is the complete opposite, although each camera has a roll cage, but the roll cage and the roll cage are independent of each other, and each camera needs to be installed into the mobile phone independently.

The Mate 60 Pro does just that.

Under this design, the angle deviation between the cameras can almost only see if the spirit guy of the final assembly has a hand trembling...

Mate 60 Pro

Although our test data does not rigorously prove this hypothesis, it does not contradict this hypothesis:

All phones that use an integrated roll cage have a decent deviation performance, and the worst is just the Xiaomi 13 Pro, which can't be seen at all without overlapping and zooming in;

Phones with multiple cameras, such as the MIX Fold 3 and Mate 60 Pro, have seen many deviations.

Some of the stacked pictures can be tightly sealed, while others can be seen crooked at a glance.

Due to time constraints, we only tested more than 20 mobile phones, and although the sample was relatively small, the results were not encouraging.

I believe that the manufacturer should be aware of this problem and have a maximum allowable skew angle in the internal quality control regulations.

Otherwise, Huawei's customer service will not be convincing and say to the up owner, "This is a normal phenomenon".

How to put it, from a rational point of view, I understand. After all, it is not a matter of a day or two for design and engineering implementation to fight each other.

But from a consumer point of view, I should be nervous, especially after this batch test, I think that checking whether the camera is crooked in the future may also become the basis of our evaluation.

Although it may not be useful for us to talk, I still hope that some friends from manufacturers can read our article and optimize the assembly method of the camera.

After all, it's 3202 years.,I'm blowing mobile phone photography every year.,Don't have this kind of bug anymore.。。。
