With the development of technology, Jobs' 3.5-inch screen is the best mobile phone size in history. The reality tells us that only the bigger and bigger screen is our aspiration. We are not only dedicated to mobile phone screens, but also eager to enjoy the experience brought by large screens for home televisions, computer screens and projectors.

However, the screen of mobile phones cannot be as large as that of televisions and displays. After all, there is a limit to the size of the screen that one hand and two hands can bear. It is impossible for us to carry a mobile phone with a 10 inch screen on the road. So, how to realize our pursuit of large screen. This time, we may find the answer from the Qingcheng VOGA V laser projection mobile phone.

Next, let me lead you to experience the changes brought about by the Qingcheng VOGA V laser projection mobile phone.

1、 Unpacking, appearance and parts introduction

Qingcheng VOGA V laser projection mobile phone adopts simple and generous packaging, and the pure black packaging box gives a noble feeling.

  Different from other rectangular packaging, the square packaging method reduces the overall thickness to a general level, and it feels great when held in one hand.  

The names of the mobile phone and the Qingcheng VOGA V laser projection mobile phone are very eye-catching. The design follows the way of "open, see, and use", and has a great experience in the overall user interaction. The double layer design is adopted for the package. On the bottom of the package, various accessories of the mobile phone are placed and a mobile phone case is prepared for the user.  

The package includes host * 1, data cable * 1, charger * 1, headset * 1, quick guide instructions * 1, warranty card * 1, protective case * 1, top card pin * 1, and a small projection bracket, which is very considerate. This bracket can jam the mobile phone and adjust the appropriate gradient when projecting, so that the mobile phone can be smoothly projected onto any plane without holding the mobile phone all the time, and you can feel the full care and ultimate user experience of the mobile phone manufacturer.  

The factory sticker of the phone also identifies the functions of each button and part of the phone. Qingcheng VOGA V laser projection mobile phone has a body length of 153.06mm, a width of 75.64mm, a thickness of only 10.28mm, and a body weight of 203g. It uses a metal back cover and feels just right.

  Qingcheng VOGA V laser projection mobile phone is designed with fingerprint unlocking on the back, which can be unlocked with a touch, and has high recognition.   The rear camera has 13 million pixels, and the front camera is 8 million pixels, meeting the needs of all users.

The CPU adopts MT6750t eight core 1.5GHz chip of MediaTek, and also supports dual cards and dual standby. The 64GB ROM and 4GB RAM configurations are almost the standard configurations of most flagship mobile phones at present. The 5.5 inch screen, 1920 * 1080 resolution, is also the standard configuration of all flagship phones at present.

The battery has 4000mAh and good endurance. It is said that it can project for 4 hours without interruption, which can meet almost any demand. But how is it actually? Let's test it in the following section.

The system of Qingcheng VOGA V laser projection mobile phone is a customized Android system.

After the phone is turned on, the user can choose whether to turn on the phone protection. You can choose to set fingerprint, or pin code, pattern and password. There are many options available.

The input method can choose the iFLYTEK input method of VOGA customized version.

At present, there are only three options for mobile phone language settings: traditional Chinese, simplified Chinese and English, which meet the needs of most Chinese.

On the top of the mobile phone is the projection port. If you have known about the previous projection mobile phones, you will know how powerful the technical breakthrough in the Qingcheng VOGA V laser projection mobile phone is. Previous projection mobile phones are very thick, but Qingcheng VOGA V laser projection mobile phones make the thickness of projection mobile phones almost the same as that of most flagship mobile phones, which is definitely a technological breakthrough.

2、 How to Exceed the Physical Limits of the Screen -- Evaluation of Projection Function

The core function of the Qingcheng VOGA V laser projection mobile phone is of course the built-in laser projection. A small mobile phone can project 720P high-definition projection, which is convenient to carry. It is simply a portable projector that can make calls, play games and chat on WeChat.

Whether it is business needs, entertainment needs, social needs, a mobile phone can meet, which is the main difference with other mobile phones on the market.

When projecting, the bracket delivered by the manufacturer is very useful. You don't need to look for objects to support the mobile phone. You just need to use the bracket to gently insert it, which can immediately free your hands. However, due to the small size of the bracket, it is also convenient to carry with you, but you also need to be careful about losing it and keep it properly.

When experiencing the projection function, the design of the projection cover of the mobile phone has both advantages and disadvantages. The disadvantage is that the manufacturer may take the sealing and dust prevention into consideration, which makes the cover extremely difficult to remove. It is recommended that a small gap be made to facilitate the removal of the projection cover. The advantage is that the projection cover has a sticky design, so that it can be easily glued to the side of the projection after disassembly, so that the projection cover is not easy to lose, otherwise the cover is too small, and it is really too easy to lose.

Even when the light is turned on, the projection effect is still excellent, but it is not suitable for long-distance projection under the light. But at the appropriate distance, the projection can be clearly seen even if there is light.

With the external handle, you can play the game under the projection, which is very convenient. It feels that the king is a matter of minutes.

Compared with the traditional projection mobile phone, the Qingcheng VOGA V laser projection mobile phone can automatically focus and project and enlarge the projection picture according to the distance between the mobile phone and the wall. The 70 inch picture can be projected 1.8 meters away from the wall, and the maximum 200 inch large picture can be projected.

However, there is a problem that needs attention. As shown in the figure, the author directly projects it onto the wall. Because of the unevenness of the lime gun, the picture you see has some graininess. If it is projected onto the screen or smooth wall or desktop, it will not appear grainy.

Even if the mobile phone is placed slightly slanted, the teal VOGA V laser projection mobile phone has the smart ladder correction function, which can make the picture still look rectangular, which can meet many use scenarios.

3、 Other function experience

Heat dissipation effect: With the high performance development of mobile phones, heat dissipation has become a major problem of today's smart phones. Play some games, and the mobile phone immediately becomes a warm baby. It is not easy to deal with the heat dissipation of a mobile phone. How about the high-performance chip+projection module of the Qingcheng VOGA V laser projection mobile phone?

After half an hour of projection test, because the projector is designed at the head of the fuselage, the head and camera parts have the highest temperature, but the highest temperature is just a warm feeling to the touch, not like other mobile phones can iron eggs. For a mobile phone focusing on the projection function, this cooling effect is very impressive, which shows that the manufacturer is very careful in the design of the overall mobile phone.

Mobile phone system: Qingcheng VOGA V laser projection mobile phone system is a customized Android system. One button projection button is designed on the main page to occupy half of the screen, which is very conspicuous and convenient. In addition, there is a permanent menu button on the right side, which can also turn off the projection on the video page with one button. The overall design is very friendly. However, due to some bugs in the new system, the buttons are repeated and cannot be clicked. I believe that it can be solved by upgrading the system.

On the whole, the customization system of Qingcheng VOGA V laser projection mobile phone can show the manufacturer's good intentions, and the mobile phone system experience is good.

4、 Summary and suggestions

Qingcheng VOGA V laser projection mobile phone, as a new generation flagship smart phone with the main projection function, is the best projection mobile phone in the market at present in terms of portability, ease of use and practicality. For the mobile phone with the main projection function, it is difficult to achieve such all-round and comprehensive performance. In terms of volume control, even with the projection function that can project 70-200 inch images, the thickness of the mobile phone is similar to that of other flagship phones, and it is the thinnest mobile phone in the market that focuses on projection, which shows the efforts of the manufacturer in this regard.

In terms of projection experience, Qingcheng VOGA V laser projection mobile phone is equipped with MEMS laser projection, achieving intelligent focusing, intelligent trapezoidal correction, and 720P high-definition projection. Among all mobile phones with the main projection function on the market at present, Qingcheng VOGA V laser projection mobile phone is an outstanding player in terms of image brightness, color restoration, or color saturation. Although it is small, it is not easy to provide a maximum projection area of 200 inches and a maximum high-definition picture of 720p.

On the whole, the performance of Qingcheng VOGA V laser projection mobile phone is commendable, and what needs to be improved may be the optimization of the system. Today, when smart phones have been seriously homogenized, the positioning of Qingcheng VOGA V laser projection mobile phone is very clear, and it will certainly occupy a place in such a competitive smart phone market.
