These functions of mobile phones are very practical but you have ignored them
|
More than a decade ago, it was still the era of feature phones. I believe many people would think that taking photos, listening to music and surfing the Internet with mobile phones were very novel things. However, today's mobile phones have more and more novel and interesting functions, and sometimes many functions are even ignored by us. Next, the editor will take stock of the functions that are easily overlooked but very practical. 1. Practical VPN function Speaking of this function, most smartphones now have it. VPN is a remote access technology. Simply put, it uses public networks to build private networks. For example, an employee of a company is on a business trip to another place, and he wants to access the server resources of the company's intranet. This access belongs to remote access. The most practical aspect of VPN technology is that you can use VPN servers to access the Internet. For example, we can access foreign websites such as Youtube, Twitter, and Facebook that are not accessible in China (so you need to learn to surf the Internet scientifically). The principle of VPN for overcoming the firewall is to remotely connect your device to other local area networks. In fact, almost all multinational and cross-regional companies use VPNs, and sometimes the government also uses them. 2. Roaming function of mobile phone manufacturers In recent years, more and more mobile phone manufacturers have begun to open international roaming service functions for their mobile phones, such as Huawei's "Skylink" and Samsung's "S Roaming". Earlier, the target population of the international roaming market was mainly business people who traveled frequently. With the improvement of domestic consumption levels, overseas travel consumption has increased significantly, and the demand for mobile data Internet access has also increased significantly. Therefore, the market for international roaming services is also growing. Although operators also provide international roaming services, the charges are expensive and it is troublesome to activate them. For example, it is not uncommon to hear news that someone was charged a huge amount of data traffic fees for posting a circle of friends when traveling abroad. However, the roaming services of Huawei Skylink, Gionee, Qihoo and Hammer are not only cheaper but also convenient to use. However, it should be noted that the roaming services provided by manufacturers can only be used on their own products, and currently only support some high-end models. For example, Hammer Roaming is built directly into the mobile phone system. It can be activated in the "Cellular Data" in the settings menu, and then select "Roaming Service" to purchase mobile roaming traffic in different regions. You don't need to change the SIM card when using it, and you can use roaming data even without inserting the SIM card. In addition, Hammer Roaming is mainly charged through WeChat or Alipay. This prepaid charging method can avoid the risk of huge traffic fees caused by "stealing" of traffic. 3. Mobile phone anti-theft function Many friends have a weak concept of mobile phone anti-theft. Once the mobile phone is lost, they can only blame themselves. However, in fact, many mobile phone manufacturers have added anti-theft functions to their mobile phones, such as the "Find My iPhone" function of iPhone phones and the mobile phone retrieval function of various brands in the Android camp. Therefore, when we use mobile phones, remember to turn on this kind of mobile phone anti-theft function and make good use of these functions. Even if you can't find your mobile phone, your mobile phone is a brick in the hands of others. Generally, if the iPhone's search function is turned on, even if the phone is lost, others cannot open it, because the service is now connected to the cloud, and no one can access the phone just by flashing it. In addition, after turning on the phone's anti-theft function, you can also remotely lock the phone or erase the data in the phone, and even see its real-time location when the device is connected to the Internet. However, the editor would like to remind everyone to be careful. When the phone is lost, some people with ulterior motives may rack their brains to get your account password to obtain the information in the phone or even flash the phone to sell the stolen goods. If they cannot easily crack the password you set, then phishing text messages will be sent every now and then. For these text messages, everyone must not believe them. 4. Power saving mode The current mobile phone hardware is developing rapidly, but the battery technology is actually stagnant. In addition to the current fast charging, more mobile phones have also added power saving mode, which is also a practical function that is overlooked by everyone. Generally, the built-in power saving mode of mobile phones has similar functions, but how much power this mode saves depends on the optimization capabilities of each manufacturer. Power saving mode For example, if the built-in low power mode of an Apple phone is turned on, power consumption will be effectively reduced. After turning it on, email acquisition, "Hey Siri", background application refresh and automatic download will be disabled, and some visual effects will be weakened or turned off. Because users are on standby most of the day, functions such as background application refresh also consume power in the background. After actual testing, turning on this power saving function will not affect the user's normal communication, and can effectively increase the standby time. 5. Professional (mobile) mode, HDR and other camera functions Although mobile phones now have more and more camera functions, most users will ignore these functions. Generally, when a mobile phone enters the camera interface, the first mode given to the user is the automatic mode, so the automatic camera function is often used by default. In automatic mode, the camera function of the mobile phone will not be fully displayed. Only by entering the professional mode can you take more interesting photos. Generally, the professional mode of the camera function of a mobile phone is also very playable. This is why the effects of different people taking photos of the same mobile phone are also very different. In fact, the rich shooting functions of mobile phones are very practical. For example, if you want to capture more details in the dark but don't want to overexpose the bright areas, you can use the HDR function. In addition, when shooting night scenes, you can manually lower the ISO and extend the exposure time to take purer photos. 6. Automatic startup and permission management of applications Applications start automatically very frequently in the Android system, which not only causes many useless programs to start automatically in the background, but also consumes more power and memory. If you want to turn off the automatic startup of applications, you need to root to enable permission management. With the upgrade of Android versions, many mobile phones can now turn off the automatic startup of applications, but this is also a practical function that is overlooked by everyone. In addition, after enabling permission management, it can not only effectively prevent the application from automatically starting, but also prevent the situation of stealing traffic. There are many software that will steal the user's traffic in the background. In order to avoid this situation, turning on permission management can freely choose software to control the use of traffic. Summary of mobile phone permission management: These functions are very practical, but easily overlooked. When you actually use them, you will find that these functions are very useful, practical and easy to use.
