According to Bige's third law of psychology, the more traces we leave in the virtual world, the more we care about personal privacy.
is fed back to daily use, which means suspicion of various apps on the mobile phone, for fear that insiders will steal personal information.
It’s not a big deal for everyone to be sensitive. In fact, over the past few years, the apps on your mobile phone have become more and more "evil".
For example, Xiao Lei just finished talking to his friend on WeChat and talked to him about " Hair Loss ". In a blink of an eye, he opened Taobao and saw that several hair growth products were recommended on the home page.
Once, it was even more outrageous. Brother Bi and I chatted a while ago and talked about the League of Legends S12 finals. We didn’t touch our phones throughout the whole process.
The result was not long after the chat, Weibo pushed me the S12-related tweet. Xiao Lei could not confirm whether the App had "listening".
But what is certain is that the big data of major Internet companies has reached the point of perfection. Users raise their fingers and the App will know what you are going to do next.
To be nice, it is thoughtful. The content is customized based on the user's portrait, but what users are more worried about is whether the App will peek at privacy.

It was difficult to balance between user privacy and App request permissions, and the relationship between the two sides was extremely tense.
At this critical moment, an app hit the gun and was scolded by users.
High-intensity Surfing probably has heard of it. This app is called -- Dewu.
Recently, a user said that his Huawei mobile phone found that Dewu deleted the photos and videos of his phone without authorization, and he was so angry that he recorded the video and posted it online to expose it.

Really deleted the local video of the user's mobile phone?
Let me briefly introduce to you if you don’t know. Dewu App is a trendy online shopping platform and is also the permanent place for Fu Ge and shoemakers. It sells some shoes and clothes.
Since it focuses on trend, most products are naturally well-known brands, such as Nike, Adi and Li Ning .
Speaking of this platform, the biggest advantage is the manual inspection process, and the seller will send the product to the Dewu warehouse first.
After passing the goods, the inspector will send it to the buyer after confirming that it is genuine.
But there is a lot of controversy about this "artificial identification" link.
Before, the old man exposed some of Dewu's flirting operations. He bought a trendy suit in Dewu. In order to verify the truth, he also spent 10 yuan to purchase Dewu's identification service.
was finally identified as the real one, but later he put the clothes on Dewu to resell them, but was identified as a fake by Dewu staff...

In addition, problems such as recharging defective products and rejecting seven-day unreasonable returns and exchanges are searched online.

The party involved in this incident, @Camizzzs, encountered the most classic after-sales dispute problem on the Dewu platform.
A while ago, he took advantage of the 11.11 deeds to buy some things inside, but after getting it, he found that there was a problem, which might be that the product was flawed.
So he thought about going through the after-sales channel and wanted to submit video data.
The key point has come. Not long after uploading the video, his Huawei phone showed this prompt:
"The deleting object was detected and deleted the video, and it has been successfully intercepted"

Although the system prompt may be a false alarm.
However, the user uploaded the evidence, and the system prompted the video evidence to be deleted.
The cause and effect are connected, and it is difficult not to make the parties involved suspect that Dewu really wants to destroy the evidence...
. After this matter was exposed on the Internet, netizens each had their own opinions.
Some people say that he believes in more than the continuous operation of the devil.

There is also a brother rationally analyzing that Dewu App just did not write standard points to the storage mechanism, which caused system protection to be triggered when deleting cached files.
So, what is the truth of the matter?
Xiao Lei has been thinking for a long time and has shared his analysis with everyone. It may not be correct. Friends who have other ideas can chat together in the comment section.
First of all, from a technical perspective, the public storage mechanism of early Android was indeed not secure enough.
As long as the file is not placed in the /data directory and the App has obtained storage permissions, you can "swish" the local storage space at will.

The so-called "shit", including new creation, uploading, deleting and secondary editing of files.
happens that domestic apps do not have strong development specifications and constraints, so it is no longer surprising that they "scare" everywhere, so the storage space of most Android phones is messy.
Some files are even infinite dolls, with four or five layers of "subfolders" covered with one layer of folders.
Ordinary users see this kind of file, but they don’t know what it is...

Xiao Lei also asked his friends who are engaged in Android development. He said that these files were created by domestic apps to continuously track user data, and even if they are deleted, there is no problem.
And now Android storage permissions are gradually standardized, and many apps can be used normally even if they do not have storage permissions.
Since the App can obtain storage permissions, it can gain such great freedom.
Is that true and natural, deleting the user's local photos and videos without authorization?
Xiao Lei thought it was OK, but it was not necessary.
We can follow Dewu's detailed response and analyze it while watching.
According to Dewu, in order to shorten the waiting time for users to edit videos, the App has adopted a temporary cache method, which is also a common solution in the industry.

However, this temporary file was created by Dewu himself. The advantage is that it will not make any modifications to the original file, and the original video on the user's mobile phone will not be affected.

In fact, there is no problem with Dewu's operation logic.
The most outrageous thing about
is its "shit" behavior everywhere. Have you noticed that the temporary files it creates are placed directly inside the mobile phone storage directory/pictures.
This is the main image storage path for Android users. The pictures we usually save on each app are basically placed here.
Because there are too many pictures stored in this path, it involves personal privacy. Huawei has added the protection function of commonly used gallery directories as early as EMIUI 9.
It will be fine if the App creates a file in /pictures, but if the file is deleted from it, it will inevitably trigger a system security warning.

Huawei's vice president of product line also mentioned at the end of function analysis:
If a third-party app does not want to be misjudged to delete the file, just add the .nomedia attribute to the temporary file in the cache directory according to the Android specifications, so that the system will not scan it.
So, now the truth is basically revealed...
The harvest did not specify the storage location according to the Android specifications, but instead simply and roughly placed the temporary files in /pictures.
and other users have finished editing the file. Dewu actively deleted the temporary file, and the file protection function of Huawei phones is directly contacted and issued an alarm...

Early Twitter client also triggered an alarm due to insufficient storage and naming.

Although Dewu has a bad reputation in normal times, from the actual situation, Dewu is still quite honest this time.
also reflects well that domestic apps like to "swine" inside the Android storage space.
is not developed according to the specifications, so don’t blame users for misunderstanding
There is a big difference between domestic Android App and overseas Android App environments.
At least mainstream overseas apps will be forced and restricted by the development specifications formulated by Google .
For example, how to design open-screen advertisements and how to formulate storage directories, there are clear and reliable standards to follow.
However, for well-known reasons, Google has become a well-known 404 company. In terms of design specifications of domestic Android Apps, they are basically more wild than the other. What is
Material Design, what is the storage space specification, Chinese-made apps cannot see it.
This leads to the "file deletion protection" function launched by mobile phone manufacturers in order to protect user privacy.
Just say that, just search on Weibo or Baidu : Delete files from a certain App, and you can find many cases of failure.
Source: Zhihu@anonymous user
There is a special storage directory for apps to store files, but many domestic apps are just too hard to "shit" on [public storage].
This does not trigger the "file deletion" prompt, it is really outrageous...
In short, this incident is a good thing to some extent, at least it has given many domestic apps a reminder.
If you don’t want to be plagued by negative news, you have to think carefully about whether the storage location of your own app is reasonable.
