　　1. Stereo Speakers

　　Stereo speakers often appear in HTC and other brands of mobile phones, can significantly enhance the ringing of the phone, the music loud speaker. Although many brand's flagship phones began to use this design, but we think it should appear in stereo speakers in each phone. 

　　2. Waterproof and dustproof

　　You can find IPXX level of waterproof and dustproof function in Sony's Xperia series phones, the phone usually allow immersion in one meter of water for 30 minutes without damage. In fact, this feature is very useful, can effectively prevent the phone by rain, dust erosion in their daily lives, but are subject to design constraints, and not universal. 

　　3. The split-screen multitasking

　　Samsung's TouchWiz interface is often integrated split-screen multitasking feature that allows the user to a screen interface hereinafter running multiple applications, LG also provides a similar function. In fact, in the case of mobile processors, RAM escalating, this function has the burden of hardware is not large, and can take advantage of the large screen mobile phone space, quite practical. 

　　4. stylus

　　Other models such as the Samsung Galaxy Note, equipped with advanced electromagnetic stylus, you can achieve a richer interoperability, especially in the 5.5-inch and above screen. 

　　5. physical mute switch
