Talking about praising flip phones

Now let's look at the advantages and disadvantages of these three kinds of mobile phones. Which one do you like best? Advantages: Straight mobile phone: simple operation, low production cost and relatively low market price, which refers to the same level as the other two shapes of mobile phones, such as motherboard screen battery. The process of producing waterproof performance is simple. Therefore, the three-proof mobile phones are all straight. Flip phone: the volume becomes smaller when the flip is closed, and the call is targeted when it is opened. The receiver and microphone conform to the human face and can introduce little external noise. This advantage is the most important for the mobile phone as a communication tool, which is unmatched by other shapes of mobile phones. Moreover, the keyboard and screen can be larger and more beautiful. Slide phone: it is very small when not in use, and can be stretched when talking, and the screen can be enlarged, which is more convenient to operate than the other two models. The cable of this kind of mobile phone is bent, and the failure rate is much less than that of flip phone in terms of material and mechanics, which has also been confirmed in trial production and inspection. Disadvantages: bar phone: the screen and keyboard seem to have their cake and ate it. The appearance is aging, and it is difficult to make creative models. The screen is easy to be damaged (the screen is the most expensive accessory in color screen collection), and the keyboard must have a keyboard lock. If you open the keyboard lock (usually two keys), it will not show its advantages of convenient operation. If the call is not well targeted, it will also bring in relatively more external noise. Flip-top mobile phone: The production cost is high (adding cables and flip-top packaging), and the operation is inconvenient. Most operations require flip-top. The process of waterproof performance in production is complicated, and almost no flip phone can claim waterproof function. It is too much trouble to produce. The failure rate of flat cable is very high. Slide phone: The production cost is high, and there is a cable, so there is cable failure, but it is a little less than the flip, and the waterproof production process is also very complicated, so this shape of waterproof phone is not produced. Call location is not as good as flip phone. It will also introduce relatively more external noise. Moreover, the keyboard area of this kind of mobile phone is generally very small. And the advantage of convenient operation is greatly reduced. Based on the advantages and disadvantages of the three models introduced above, I personally think that if you want to buy a mobile phone with the same function to save money, you should choose a straight mobile phone. If you want to have good call quality and beautiful appearance, you should choose a flip mobile phone, which is convenient to operate, small in size and beautiful in appearance, and you should choose a slide mobile phone.
