In terms of imaging, DXOMARK believes:

The image quality of the Mi 14 is significantly improved compared to its predecessor, the Mi 13. Images were detailed and low-noise in most test conditions; the neutral white balance makes the device ideal for landscape photos. The Xiaomi Mi 14’s zoom performance stands out among its peers, delivering detailed images in telephoto mode. In addition, the video experience of Xiaomi Mi 14 has also been greatly improved. Whether indoors or outdoors, the target exposure is accurate, the dynamic range of the video is wide, and the detail and texture processing are also good.

However, when taking portrait photos outdoors, facial contrast is low under strong light and backlight conditions, and sometimes overexposure occurs; when shooting sports scenes, some artifacts may appear, resulting in unnatural photo effects. In terms of video: although autofocus has made some progress compared with the previous generation, it is still unstable in panning scenes; in low-light environments, the video imaging noise is more obvious than similar products, and the rendering of human skin color is not accurate enough.

In terms of screen, DXOMARK evaluates:

The screen of Xiaomi Mi 14 can provide users with an excellent user experience in all usage situations and has stable readability; the screen is very smooth when browsing web pages or playing games; in low-light environments, the screen brightness can be adjusted well, and indoors The color performance in the environment is also excellent.

Although Xiaomi 14 has improved artifact management compared to Xiaomi 13, the screen still flickers to a high degree in default mode (however, the device has an anti-flicker function to limit this phenomenon); although the device released by Xiaomi The peak brightness can reach 3000 nits, but our engineers found in testing that the device’s maximum brightness can only reach 2740 nits when watching HDR video content, which will result in insufficient brightness and loss of details in dark parts when watching HDR10 videos.

The post Xiaomi pushes HyperOS development version for 14 series phones appeared first on TechGoing.

Today, Zhang Guoquan, director of Xiaomi’s phone system software department, explained this feature and said that the “UltraSpace storage expansion” function will not pose a lifespan risk to UFS at all, and older models do not support upgrades.

In addition, Xiaomi has contributed the standard to the UFS Association. In order to respect the originality, Xiaomi requires chip manufacturers to provide a time protection period. In the near future, all major phone manufacturers should adapt to this function.

The complete content is as follows:

 Regarding the storage expansion function mentioned at the Xiaomi Mi 14 press conference, after reading everyone’s feedback these days, I feel it is still necessary to explain the ins and outs of this function. The text is very long. Students who are not interested in technology can just read the question and the first paragraph. answer

 Why do we need this function?

 I am ashamed to say that in the past few years, MIUI has been criticized for being "bloated". In the past two years, it has been vigorously rectifying it. From last year's Razor Plan to this year's storage expansion, it is the same line. We must say goodbye to bloat.

 Project Razor 1.0 aims to ensure that except for a few basic functions, other system applications can be uninstalled. Project Razor 2.0 aims to achieve the smallest system firmware, plus storage expansion, to ensure that users can use the maximum space.

 The ultra-simplified Xiaomi ThePaper OS is not only extremely fast and light, but also saves a lot of space. With the hardware expansion of 8GB, you can gain up to nearly 20GB of additional space compared to other flagships. In addition, the file deduplication and dynamic compression functions in the OS also improve storage efficiency. It is not only larger, but also more "durable". Taken together, after long-term use, it can store more than 30 or even 40G of data.

 What is the technical principle? Are there lifespan risks to UFS?

 Absolutely not, everyone can use it with confidence, trust the professionalism of Xiaomi and chip manufacturers, and don’t be led away.

 Let’s briefly introduce bad block replacement management. Since storage devices generally can only replace them with units with reserved space after bad blocks are found, once there is not enough reserved space, the memory chip will be completely unusable. In addition to reserving sufficient space based on user habits, we also optimize Cache management to reduce erasure and bad block generation. We also support cloud control to adjust the bad block reserve area according to user conditions after long-term use, ensuring System stability. According to the current model of heavy users, under the condition of writing 40GB of data every day, the 256GB expansion chip can still guarantee more than 10 years, and the 512GB can last more than 20 years. Please rest assured.

 To ensure the best storage experience, it is necessary to achieve in-depth collaboration between the host file system and UFS. This has been reflected in the previous FBO refresh storage function. With the same concept, Xiaomi has also deeply intervened in UFS resource management based on file management on the host side. , realize "data is not written unless necessary (UFS)" through software, and "write data is not migrated unless necessary" is realized through software + firmware, which not only reduces the amount of writing, but also achieves better wear-leveling and WAF

 Can older models be upgraded to support it?

 It requires phone manufacturers and supply chain manufacturers to cooperate, and calibration needs to be done during phone production, so older models do not support it.

 The same Xiaomi 14, why are some versions not supported?

 For the sake of supply chain security, we purchased a number of memory chips. Although Xiaomi shared all the technology with suppliers, some manufacturers had not had time to adapt. In fact, there were objections a few days before the launch. Finally, Mr. Lei made the final decision: OK Don't waste technology. Just explain it clearly to everyone. If you have more 8G/16G, just enjoy the happiness brought by technology. It's normal if you don't have it. I hope everyone understands.

 Driven by Xiaomi, mainstream memory chip manufacturers at home and abroad will gradually adapt.

 Can other manufacturers use this technology?

 Xiaomi has contributed the standard to the UFS Association. In order to respect the originality, we require the chip manufacturers to provide a time protection period. In the near future, all major phone manufacturers should adapt to this function. Since its establishment, Xiaomi has always hoped to work with all manufacturers to promote industry progress. This does not need to be explained, everyone should see it.

According to Lei Jun’s previous introduction, the actual real space of a phone storage with a nominal 256GB actually exceeds 275GB. Among them, 93.1% of the space is actually usable by users, and the remaining 6.9% is called Over Provision, or OP for short, which is the space occupied by the internal management of the memory. This part of the space cannot be used during the use of the phone.

Xiaomi has worked closely with memory manufacturers. First, Xiaomi has modified its space management strategy to compress the space occupied by the OP area from 6.9% to about 3%. This process requires an in-depth understanding of the working principle of the memory to ensure that the performance and life of the memory will not be affected while compressing the OP area space. After many tests and optimizations, Xiaomi found an ideal balance point.

Xiaomi then added a new logical address mapping range to the ThePaper OS file system, allowing it to manage this part of the “new space”. During this process, Xiaomi needs to deeply customize the file system to ensure that it can manage this new space correctly and efficiently. Xiaomi engineers finally achieved this goal after countless experiments and tuning.
