Many people are using the dolphin browser recently. The Android browser of the dolphin has some special advantages over other browsers. Some useful friends know how to help.

The dolphin browser Android V8.2 adds the "dolphin sonar" feature. "Dolphin sonar" uses intelligent semantic recognition technology to enable the browser to better "understand" the natural language. Users only need to tell the dolphins their own needs in their most used words to be satisfied. After you open the dolphin browser, you only need to shake your phone to switch to the dolphin sonar page. Then, if you want to browse the Sina web page, you can say simple phrases such as "Sina", "Open Sina", and "go to Sina, you can also use more colloquial sentences such as "I want to go to Sina" and "help me go to Sina", which can be precisely recognized by dolphins. "Dolphin sonar" truly makes browsers better understand people.
The dolphin browser Android V8.2 also supports offline reading. Open the dolphin browser, go to the "Dolphin center", and click the "offline reading" icon. Then, you can load 100 pieces of news into your mobile phone and read it anytime, anywhere. This feature is a good news for users who often like to watch news on their mobile phones, because you no longer have to worry about having to watch news on public transportation or subway.
The dolphin browser Android V8.2 also optimizes the gesture operation interface, making it easier and more convenient to use the gesture interface. Through the dolphin button at the bottom of the browser, you can go to the dolphin sonar or gesture operation interface. These two interfaces can be easily switched through the button at the bottom.
In addition, the new dolphin browser adds the home page settings, allowing you to set the home page button in the address bar.
Like Android, the iPhone's dolphin browser also integrates the dolphin sonar feature, allowing you to access the site you want to access through the method you have mentioned. Shake your iPhone to start the dolphin sonar and tell the dolphin the page you want to visit. Even a very colloquial sentence, such as "I want to go to Sina", the dolphin can be accurately identified. Dolphin sonar also supports the Voice Input Function to directly tell the dolphin What You Want to input, and the dolphin will automatically help you complete the voice input. In addition, you can use the voice to implement some basic page operation functions, such as forward and backward, switching the night mode, and sharing to Sina Weibo.
The iPhone's dolphin browser has made some amazing improvements in details, such as adding the font size adjustment option in settings, you can set the font to normal, large, and super-large. For example, smart phones can reduce the brightness of the phone screen, automatically adjust the most appropriate brightness for users, and protect your eyes.
