A few days ago it became known that replacing the screen on smartphones of the iPhone 13 line in unauthorized service centers will disable the Face ID function, even if the display is original. It turned out that in this situation everything is not so unambiguous and simple, but there is still a method to get around this problem.
Information and thoughts on this matter were shared by the specialists of the iCorrect company, which specializes in the repair and maintenance of various modern equipment.
Do you need to start by looking at how Face ID actually relates to the screen? At first glance, nothing at all, because the TrueDepth module is not connected to the screen, but to the motherboard. The reason for this relationship lies in Apple’s approach to designing its smartphones, and this approach is not new.
So, the screens of Apple smartphones have a special chip through which the device interacts with the display. In particular, it is this chip that acts as an ADC, converting the signals of the sensor layer from the user’s clicks into digital signals transmitted to the smartphone’s processor. Before the iPhone 6s, such a chip was located directly on the smartphone’s motherboard, but in the iPhone 6s it was transferred to the display.
In the iPhone X, the Cupertino giant expanded the capabilities of this chip, which began to act not only as an ADC, but also was responsible for activating the True Tone function. It is for activation, not for its work. As a result, on the iPhone X, unauthorized replacement of the display led to the disabling of the True Tone function. Everything was realized simply. In the same screen chip, which is an integrated circuit, an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip was embedded. As a result, every time the iPhone was launched, it read the True Tone activation code from this microcircuit. And if you replace the screen yourself, even with the original one, the function still did not work.
That is, the problem in such cases is not in the screen itself, but in a special chip that is part of the display module.
But in the case of the iPhone X, Chinese craftsmen quickly got the hang of transferring data from the original chip to the chip on non-original displays, since the microcircuit allowed to read and write data.
With the iPhone 11, Apple has complicated its idea by adding another read-only memory (ROM) chip to the same IC. As a result, it was no longer possible to simply copy its data to another similar chip. As a result, on devices of the iPhone 11 line, with an unauthorized replacement of the screen, not only did the True Tone function disappear, but also a message constantly appeared that the smartphone could not verify the originality of the display. But, as we already understand, not the display itself, but only its chip.
In addition, Apple began to implement the same chips in batteries, and in the iPhone 12 line a similar solution was for some reason implemented for the main camera module, although there are simply no fake camera modules for the iPhone 12 on the market.
And now we come to the iPhone 13 line. In new smartphones, the same chip is now also responsible for activating Face ID. However, the bottom line is that the source believes that this very interaction is a bug in iOS 15, and in fact, Apple did not plan to establish such a relationship in this generation. Most likely, in the next updates, this connection will be broken. The source’s opinion is that this is a groundwork for the future generation, when the Touch ID fingerprint scanner will be integrated into the iPhone screens. And the same chip will be responsible for the operation of this sensor, as is already implemented in some Samsung smartphones.
In addition, the source believes that in fact, in this way, Apple is fighting primarily not with unauthorized service centers, but with Chinese craftsmen who benefit from the ability to easily replace everything in the iPhone, since you can earn a lot from this.
As for the opportunity to bypass the protection at the moment, it is there. Everything is very simple in essence, but difficult to implement, because you need to solder the same chip to a new display module when replacing it.
Samsung trolled the bangs in the iPhone, and will eventually use it in the Samsung Galaxy Tab S8 Ultra
Prominent informant Steve Hemmerstoffer, aka OnLeaks, has released the first computer-generated images of the Samsung Galaxy Tab S8 Ultra flagship tablet.
The biggest design innovation of the Samsung Galaxy Tab S8 Ultra should be a bang-shaped cutout. Despite the presence of this element, this tablet, like the recently announced MacBook Pro laptop, does not support 3D facial recognition.
It is worth remembering that after the release of the iPhone X, Samsung released a whole series of black PR videos in which it made fun of the large cutout in the screen, which was very unusual at that time. After a few years, the company doesn’t seem to regard bangs as the same ridiculous element as they once did.
The source adds that only the Galaxy Tab S8 Ultra will receive such a notch, while the Galaxy Tab S8 and Galaxy Tab S8 + will not have bangs. In terms of specs, the Samsung Galaxy Tab S8 Ultra will have a 14.6-inch display, the Galaxy Tab S8 will have an 11-inch display, and the Galaxy Tab S8 + will have a 12.4-inch display.
Steve Hemmerstoffer at the beginning of the year published high-quality renders of the Samsung Galaxy S21 and Galaxy S21 Ultra smartphones, which were later fully confirmed.
Full redesign of iPhone 14: periscope camera and small hole in the screen
According to Mydrivers, LG Innotek is developing a periscope zoom lens for Apple, which is expected to be used in iPhones from 2022 or 2023.
Apple’s rival Samsung pioneered the periscope zoom lens in the Galaxy S20 series launched in January last year. Many other Android-based flagships from Huawei, Xiaomi, Oppo and other companies also actively use similar modules.
In the iPhone 13 Pro, despite using new image sensors and larger lenses, the optical zoom is only 3x. The difference with Android flagships remains very, very large.
The addition of a periscope camera should noticeably change the design of the rear panel. And if you consider the rumors of ditching the bangs in favor of a hole for the front camera, then the iPhone 14 may well bring the biggest design update since 2017, when the iPhone X hit the market.
The presentation of the iPhone 14 is expected in September next year.
This is what the Xiaomi 12 Pro might look like. The smartphone was shown on a new render
A Chinese insider has published a render of a new smartphone – according to him, this is how the Xiaomi 12 Pro will look. The device in the picture does not strike attention with design delights – there is still the same embedded front camera and a display bent onto the sides, as a result of which the screen does not have traditional side frames.
This image is generally consistent with rumors that the Xiaomi 12 screen will change slightly compared to the Xiaomi Mi 11: the novelty will simply use the latest generation Samsung AMOLED E5 panel with an embedded front camera – that is, there will be no sub-screen camera. The display will be curved, but it will not bend in all four directions – this decision Xiaomi will refuse.
According to the latest data, Xiaomi 12 will be released in December. The smartphone is credited with the Qualcomm Snapdragon 898 SoC, a triple camera with 50 MP sensors, a 5000 mAh battery, support for fast charging with a capacity of 120 W (wire) and 50 W (wireless).
