Don't Scan That QR Code Yet, Do This First and Thank Me Later
Before scanning the QR code, did you know that the scammers will secretly replace the QR code, induce you to leak personal information or even steal money? That's right, we've reported similar incidents in 2023. As time comes, these scams are still rampant and there is no sign of slowing down. But the good news is that you can protect yourself by using a secure QR code scanner instead of just using a regular QR code scanner.
Ordinary QR code scanning tools will only decode and jump directly to the link page, without verifying security at all. The security scanner will check whether the target link is safe before you access it. The following are several safe QR code scanning applications that I personally test and are willing to recommend in actual use.
3 Lionic secure QR code scanner
Lionic is a lightweight, superfluous security app that I love using. If you use QR codes to download apps, open websites, or make payments, this tool is very suitable.
It is less than 6MB on Android, and the iOS version is only about 15MB, which almost does not take up any space on the phone. The interface is simple and intuitive, and the operation is simple, although it cannot customize settings or functions.
The annual fee is $6 and is as low as $2 in some areas. It offers a 7-day free trial and no ads throughout the whole process - this is a very plus. Maybe it can help you avoid the parking lot fee table QR code scam in 2023.
Supports multiple types of QR codes to improve protection capabilities in all aspects. After installation, just register an account, select the plan (including free trial), and start scanning the code safely.
The built-in flashlight switch is convenient for scanning in dark light environments; there is also a "Photo Album" tag, which allows you to read QR codes sent by others from the mobile phone pictures, which is very practical.
After the scan is completed, the system will automatically generate a security report to tell you whether the link is suspicious. Want to check again in the future? Click "History" to view all scanned links, including date, URL and security status.
2 Trend Micro QR code scanner
Compared to the almost free price of Lionic, the Trend Micro is completely free to Android users and has no ads. iOS users need to use the Trend Micro Mobile Security app (the app is about 130MB and requires subscription). However, Android users can directly enjoy a pure experience.
As a veteran network security manufacturer, this QR code scanning tool from Trend Micro is also my favorite. With a volume of less than 6.5MB, it is perfect for devices with tight storage.
Unlike Lionic, no registration or login is required, and it is ready to use. The interface is simple, but the label is not clearly marked, so you may need to explore it for the first time.
In addition to identifying malicious links, it can also set up automatic opening of secure web pages and let you specify the default browser:
- Click the three dot menu in the upper right corner
- Select "Automatically open secure web pages"
- Click "Let me choose" to set the browser
Like Lionic, it supports importing QR codes from the album (there is a photo icon at the bottom), and also has a flashlight function to cope with low-light environments.
Although ads are not displayed, you are occasionally prompted to upgrade to the full Trend Micro mobile security suite to protect against phishing, malware, and "Quishing" (QR code-based phishing attacks).
1 Sophos Intercept X QR code scanner
Unlike the former two independent applications, Sophos' QR code scanning is integrated into its Intercept X for Mobile security suite, which is available for free on iOS and Android.
The volume is about 27MB before installation, which is not large, but if you just want to scan the code function, you may feel that it is over-functional. However, if you haven't installed mobile security software yet, this free tool has a very cost-effective performance: in addition to QR code protection, it also provides malicious website blocking, application scanning, two-factor authentication, password management and other functions.
The interface is clean but the functions are complex. There are many steps to set up for the first time and there are many permissions to apply for it, which makes me feel a little uncomfortable.
Another thing that is not very satisfied is that the installed apps will be automatically scanned for the first time, and there is no obvious shutdown option (the subsequent scan time can only be manually scheduled).
But I really like its built-in link detection function, which can be turned on in the "Cybersecurity Section".
To use the QR code scanning function, follow these steps:
- Open the app and click on the menu in the upper left corner
- Select "QR Code Scanner"
- Scan after authorizing the camera permissions
The scanning process is smooth and fast, but it lacks several basic functions: you cannot read QR codes from the album, there is no flashlight, and no history - I think these are basic configurations.
During the testing process, I also found that the results of different tools conflicted. For example, Trend Micro marked //m.sbmmt.com/link/23d03ac4112de862b36367b92a12104e as dangerous, while Lionic and Sophos were judged as safe. In this case, I will cross-verify multiple online link testing tools, such as VirusTotal, Bitdefender and IPVanish link testing services - just like listening to more doctors when you are in a doctor. In the end, these tools confirmed that the link was risk-free.
Although this approach seems a bit too cautious, I would rather spend a few more seconds to confirm than be invaded for a moment of negligence. In short, don't blindly scan QR codes of unknown origin, especially those appearing in stickers, posters, text messages or public places. Only by staying vigilant and working with security scanning tools can you truly protect your digital security.

According to September 15, this afternoon, several bloggers forwarded the new avatar of Xiaomi's official Weibo account - the appearance pictures suspected to be the Xiaomi 17 series. Afterwards, Xiaomi's official Weibo account quickly changed back to its old avatar. Judging from the picture, the design details of the new phone are consistent with the revelations. The appearance has changed dramatically. I gave up the upper right corner rectangle scheme that has been used for three generations and changed to a horizontal large matrix camera similar to the iPhone 17 Pro. At the same time, the camera module is equipped with a secondary screen, paying tribute to the classic flagship Xiaomi 11 Ultra, and there are many new interactive gameplay and new functions. Earlier today, Xiaomi officially announced the Xiaomi 17 series, and the new phone will be released this month. The product line includes three models: Xiaomi 17, Xiaomi 17 Pro, and Xiaomi 17 ProMax, which will bring global

On September 16, as previously expected, Xiaomi Mobile's official Weibo officially revealed the highlights of the appearance design of Xiaomi 17 Pro and Xiaomi 17 ProMax - equipped with an unprecedented "Miaoxiang back screen", which has an additional display area compared to the iPhone 17 series. This innovative design, which Lu Weibing calls "bringing something new to the industry", marks another bold breakthrough in Xiaomi's product form. According to the official video display, "Miaoxiang Back Screen" has a variety of practical functions, including custom clock theme, rear camera view preview, and controlling operations such as Xiaomi Auto App. In the future, it may exert more interactive potential in the "people-car-home full ecology" linkage. Zhang Guoquan, head of Xiaomi Mobile System Software Department, also initiated it on social platforms

The latest news on September 18th, Huawei HarmonyOS6 has launched multiple rounds of preview version push for developers, and has recently opened the experience qualification to some users who have tried it out for the first time. According to user feedback, the current system name no longer displays the "NEXT" suffix, and it is officially renamed to HarmonyOS6.0. Huawei initially proposed the name HarmonyOSNEXT for the first time at the developer conference in August 2023, aiming to mark the Hongmeng system entering a new stage of development and realizing true native self-development. HarmonyOSNEXT's most core breakthrough is to completely adopt the underlying system architecture developed independently, completely remove the Linux kernel and Android AOSP code, and only run applications based on the HarmonyOS kernel.

On September 16, Zhou Yibao, the head of the OPPOFind series product, revealed that the OPPOFindX9Pro will become the first truly 200 million pixel flagship model in the industry. 1. The quality and quantity of the true 200 million light with the largest inflow volume are always the core of imaging quality. FindX9Pro is equipped with a new 200-pixel telephoto lens, innovatively adopts a floating optical mirror group design, and integrates OPPO's self-developed super crystal blue glass technology, combined with F2.1 large aperture, and a new generation of 200-pixel large-sole sensor to achieve the highest telephoto light inlet performance among flagship mobile phones. 2. The primary condition for achieving "true 200 million" at the peak of optical accuracy is to meet the optical resolution standards, and this problem has long troubled the industry, and it is difficult to break through traditional manufacturing accuracy alone.

According to September 15, this afternoon, the Weibo topic "Xiaomi 17 Wang Teng" was on the hot search list. Xiaomi President Lu Weibing announced that the Xiaomi digital series will usher in a major upgrade, and the new Xiaomi 17 series will compete head-on with the same iPhone. The Xiaomi 17 series released this time includes three models: Xiaomi 17, Xiaomi 17 Pro and Xiaomi 17 ProMax. Some netizens pointed out that the total strokes of Wang Teng, the former general manager of REDMI brand, were 17 strokes, which happened to echo the name of Xiaomi's new flagship "Xiaomi 17". This coincidence quickly sparked heated discussions among netizens. Regarding the upcoming Xiaomi 17 series, Lu Weibing said that the series is a culmination of Xiaomi's high-end strategy accumulated over the past five years, marking a key transformation of the digital series, and the entire series achieves cross-generational improvement in product strength.

On September 12, Huawei's three-folder mobile phone MateXTs Extraordinary Master officially launched its first sale. As expected, it was sold out immediately. According to feedback from many consumers, Huawei's official mall showed that the products were sold out as soon as it was launched, and the rush to buy was extremely popular. Based on the previous pre-sale situation, MateXTs has staged a "second-win" market on Huawei Mall, JD.com, Tmall and other platforms, and offline stores have also queued up to buy. It can be foreseen that this model will face a shortage in the short term, and it is almost inevitable that the price increase will be sold through third-party channels. According to supply chain information, Huawei's initial stock volume for MateXTs is about 400,000 to 600,000 units. Although it has increased compared with previous generations, it is still difficult to meet the hot market demand. Huawei MateX

On September 16, the AI application industry data released by QuestMobile in August 2025 showed that Xiaomi's Super Little Ai Assistant is far ahead of similar products with an activity rate of 37.7%, ranking first in the industry, and becoming the AI assistant with the strongest user stickiness. At present, the AI assistant user coverage rate of mainstream mobile phone manufacturers is close to the ceiling: OPPO, Xiaomi and Huawei's AI assistant users account for 70.9%, 70.4% and 56.8% respectively, but there are obvious differences in actual usage activity. Specifically, the activity rate of OPPO Xiaobu Assistant is 28.6%, Huawei Xiaoyi is 25.5%, and vivo Blue Heart Xiao V is 27.0%, both significantly lower than Super Xiaoai Assistant. In terms of user usage frequency,

According to September 16, the OPPOFindX9 series will be released in October, and the new phone has now entered the preheating pace. Today, Zhou Yibao, the product manager of the OPPOFind series, announced that OPPO has created a self-developed eye protection screen from the source, and the OPPOFindX9 series will be launched in the world for the first time in all scenarios. Zhou Yibao said that OPPO has found a leading domestic screen factory and a time-honored state-owned enterprise: Tianma, which has exclusively customized and built OPPO's exclusive highest-spec screen production line. At the same time, in OPPO's own intelligent manufacturing center, the industry's top OPPO self-developed display scientific production lines have also ushered in a new upgrade, and the two high-end self-developed production lines are just to create a good eye protection screen. According to reports, through OPPO's self-developed screen dual production line mode,
