The concept of mobile phone+projection was mentioned many years ago, but so far many mobile phone manufacturers dare not set foot in this concept. There are several reasons. One is the battery, the other is the projection brightness, and the other is the internal space of the phone. Samsung once released a smart phone called Galaxy Beam, which supports projection function. However, due to its poor projection experience and the endurance of the devil, it was not recognized by the market. Since then, even Samsung, which has such strong hardware technology, has never tried to touch this field again. Even this year's Moto Mods shadow projection module still has some congenital deficiencies in projection brightness and endurance, and the combination price is expensive. In fact, for the exploration of black technology, domestic manufacturers are not inferior to international giants. Shenzhen COCOPICO, a traditional micro investment manufacturer, has brought a projection mobile phone COCOPICO M1 with 180 lumen projection module and a maximum projection of 80 inch screen. thank Love to play computer games The platform provides a free trial opportunity for this product. Now let's share with you the true black technology of this projection phone.

Unpacking

The packaging style of M1 is similar to that of many mobile phones on the market. The pure black box is somewhat low-key, which reminds me of the packaging style of hammer or Meitu mobile phones. But Coco Pico's English seems to be cool at first sight. Of course, we are reminded from the Rose Gold portable cinema that this is not only a mobile phone, but also a micro projector.

After taking out the outermost package, the inner packaging box adopts a book like flip style. It can be seen that, at least in the packaging design, Koko M1 is very careful.

There is an internal letter from the Kekezhuo team to the trial partners. It should be noted here that this trial version is not an official version, but an engineering version. The official version may be different.

Take that letter and you can see the real face of the mobile phone. From the positive perspective, this projection mobile phone is not much different from the traditional smart phone, nor does it appear rigid.

Take out the mobile phone first. Some accessories of this projection mobile phone are hidden in the lower layer of the box. Including card pins, power adapters, Micro USB data cables, warranty cards, manuals, etc. The power adapter adopts the specification of 5V 2A, which is rough in workmanship. It should be because of the engineering machine version.

On the whole, it can be seen from the package that Kekezhuo Projection Mobile Phone M1 has made some efforts to give people a sense of high-end. Of course, due to the engineering version, the details of some accessories are slightly rough.

appearance

M1 comes with a plastic film. As a streaker, I don't like a film that affects the pleasure of actual mobile phone operation, so I must tear it off. Every time you tear the film off a new mobile phone, there will be an inexplicable sense of pleasure. Do you have this feeling?

After the film was torn off, it was really refreshing. The front of the Kekezhuo projection mobile phone M1 was the same as that of the traditional mobile phone. The front was a 5.5 inch screen covered with 2.5D glass, but the resolution was slightly lower, only 1280 × 720.

On both sides of the top earpiece, one side is a 200W pixel front camera. On the other side are light and distance sensors. The black version is hidden deeply, so you can hardly see it.

There are no virtual or physical buttons at the bottom of the phone, so the design is relatively simple. It is also doomed that this phone uses the design of virtual buttons on the inner screen. Bug said he didn't like it.

Compared with the traditional smart phones on the market at present, the first impression of M1 is still a little thick. The measured thickness is about 14.5mm, which is almost the same as that of two iPhones. However, if we compare it with the micro projection, the thickness is actually thinner.

The most special thing, of course, is a projection module on the top of the phone. The lens is protected by a metal frame. M1 adopts optical coating precision lens, imported Texas Instruments 0.3 EM DLP projection technology, OSRAM LED light source, and its service life can reach 30000 hours. The specific projection effect will be analyzed slowly in the afternoon. In addition to the projection lens, the top of the phone also includes a power button and a 3.5mm headphone connector.

There is a manual adjustment knob on the side of the projection module. Due to the cost and technical limitations, it is not realistic to do automatic focusing on such a thin mobile phone.

In addition to the silvery white projection module, the back of the fuselage is made of a blue integrated plastic back cover, and the surface is treated like metal paint. The 1300W pixel main camera and flash light in the upper left corner have obvious protrusions, but fortunately, they have a layer of metal protection. The author is thinking, since the fuselage has been made so thick, why should the camera protrude? Is it really to follow the trend?

The biggest advantage of M1 over ordinary smart micro investment products may be that it is still a mobile phone that supports 4G. When there is no wireless network, many smart micro investment products on the market immediately become blind, and M1 can continue to enjoy the pleasure brought by 4G networks. The card slot adopts a 3-in-2 structure, which supports dual cards and dual standby, and also supports memory expansion of up to 32GB.

The upper button on the right side of the phone is not our usual power on button, but the projection button. Long press can achieve one button projection, and the lower bar is the volume key.

The bottom is Micro USB interface, and the speaker is designed symmetrically. However, I am very responsible to tell you that the opening on one side is fake, but only a noise reducing microphone.

In general, as far as the appearance is concerned, Kekezhuo projection mobile phone M1 can be said to be full of personality. It should be considered as one of the thickest mobile phones, but it is also one of the thinnest projections. Apart from the projection module, the appearance is not very different from the smart phones on the market. However, it may be due to the engineering machine, and the details are still slightly rough. I hope the official version can improve.

From the mobile phone system three years ago

It has been 8 or 9 years since the emergence of Android system, and now Android has developed to 7.0. Most mainstream mobile phones on the market are at least using customized systems above Android 6.0. When I turned on the Coco M1 projection phone, I saw a strong sense of retro, just like opening an Android phone 3 or 4 years ago.

M1's system uses the system developed based on Android 4.4.4, which is really a bit eye dropping. The icon of the system is also the popular mellow style of 3 and 4 young people, with three Android King Kong virtual keys built in. The top of the screen slides down to export the status bar; You can add some plug-ins, better wallpaper and other operations by drawing on the bottom. In short, it is a retro Android style. Fortunately, the system is smooth, and there is no application suspended death or system crash in the actual use process.

With one press, the shotgun becomes a cannon

The real selling point of M1 still lies in the built-in projection function of the mobile phone. Click the projection icon in the application bar at the bottom of the phone, or long press the projection button on the right side of the phone to open the projection module on the top of the phone to achieve dual screen display.

Kekezhuo M1 projection mobile phone adopts the DLP optical projection module of Texas Instruments, and selects the German OSRAM LED as the light source. Its service life can reach 30000h, the maximum brightness is 180 lumens, and the projection image resolution is 854x480. The brightness of the projection determines that the light in the daytime is sufficient for you to watch.

At night, when the light is turned on, the picture still has some obvious whitening. Of course, reducing the projection size can significantly improve the brightness of the picture.

When the light is turned off, the effect of projecting the small steel cannon appears, the picture is very clear, and the color gamut reaches 100% NTSC. The projection ratio of M1 is 1.4:1. A 33 inch screen can be seen from the mobile phone 1 meter away from the projection screen or white wall, and 66 inches can be seen from the mobile phone 2 meters away. Of course, the farther the distance is, the larger the projection size will be. However, the best viewing distance should be 0.5-1.5 meters, which can ensure the brightness and quality of the screen. The projection size should be between 16.5 inches and 50 inches. Next, a group of live shot projection pictures are compared with the original picture to see how the projection quality of M1 is. The test is about two meters away from the mobile phone, and the projection size is close to 70 inches.

Three color chart test shows that the color restoration of the projection picture of Kezhuo M1 is very accurate through comparison. The red, blue and green colors are very close to the original image, but slightly darker in brightness.

The projection effect displayed by M1 is amazing after lighting at night. Unexpectedly, such a small projection module can transmit such an effect. From the comparison of several groups of photos, first of all, the color is very close to the original picture, and the brightness is also very good. Of course, the waxy yellow feeling brought by low-cost projection cannot be avoided. There is also a resolution of 854x540. The image is a little less exquisite. Of course, as a projection mobile phone with such a small size, the projection effect is basically satisfactory.

It only needs a bracket to open the projection of the mobile phone, and the picture is projected on the ceiling. With her beloved, you can lie in bed and watch blockbusters romantically. This wonderful feeling can still be brought to you by the Kekezhuo M1 projection mobile phone.

Hardware: In fact, you can pay more attention

As for other mobile phone configurations on M1, it is really disappointing. The CPU uses the LC1860 5-core processor of Lianxin Technology, with a maximum main frequency of 1.5G, a storage capacity of 2GB, a storage space of 16GB, and a maximum expansion of 32GB. This configuration is even inferior to the current Hongmi, Meizu, Huawei and other 1000 yuan entry models, which is really embarrassing.

It can be seen from the score run of Android Rabbit that only 23000 points were scored, which is really low. This score is basically the same as that of Android camp four years ago. It can be seen from the configuration that the manufacturer still weakens the mobile phone configuration, focusing on the projection function. This configuration can deal with some video apps, WeChat, QQ and other social software. It is not a big problem, but please take a detour, game party. Of course, the mobile phone configuration is determined. It is difficult for Kezhuo to become a major player in daily use.

The screen adopts 5.5 inch 720P resolution, full fitting process, and slightly low PPI. However, the display effect in the actual use process is fairly good. If not compared, the graininess is not obvious. The maximum brightness of the screen is fairly good, and there is no problem with the color accuracy and contrast. Apart from the resolution, this screen is still qualified.

The M1 projection mobile phone uses a 1300W pixel camera. The camera page is still in the original style of Android 4.4. There are a variety of shooting and playing methods, including automatic, candlelight, party, fireworks, anti shake, sunset, snow, beach, theater, night portrait, dynamic, normal, sports, night scene, scenery, smiley face, portrait, panoramic, two-dimensional code and up to 19 shooting modes, It is rare on mobile phones at present. How about the specific imaging effect?

From the sample photo, the M1 photo is generally dark, and the effect of cloudy days is taken on sunny days in the daytime. However, the color is still accurate, and the image resolution is relatively satisfactory. However, compared with the smart phones in the current market, there is still a significant gap.

When it comes to the dim light, the performance of M1 is worse. While the picture is darker, the noise is really moving, and the focusing speed is also slower. In general, compared with smartphones on the market, the main camera of the Kezhuo M1 projection mobile phone is somewhat unsatisfactory, but it can still cope with occasional emergencies.

Power consumption and endurance

As a projection mobile phone with LED bulbs, the author was worried about the heat at the beginning. After all, projection always reminds people of high heat. However, when actually used, I was surprised to find that the heat of M1 projection mobile phone was well controlled.

Test environment: While charging, projection plays online movies. Half an hour later, there was a slight heat on the top of the phone, which was not hot. The maximum temperature on the front was 34.1 ℃, while the maximum temperature on the back of the phone was 37 ℃. This temperature is relatively low for an ordinary Android machine, not to mention that M1 is still projecting. We can not worry too much about the fever of mobile phones.

Endurance: Kekezhuo M1 is equipped with 3100mAh battery. If it is a 5.5 inch ordinary intelligent machine, its capacity is just right. As a projection, it is really worrying. In practical use, it is found that the consumption of one hour is about 45% when the projection is continuously viewed. If the projection is continuously viewed, the endurance of 2-3 hours can be basically guaranteed. However, when the power is less than 35%, automatic shutdown occurs many times during the test. It seems that when the power is insufficient, the power supply for the projection is still insufficient. After the power is plugged in, the projection can be normal.

epilogue

If the projection and the functions of the mobile phone are divided into two parts, the Kezhuo M1 does not stand out. Compared with the smart micro projection on the market, the projection brightness is still significantly weaker; In terms of mobile phone configuration, it may not be as good as that of the red rice mobile phone with several hundred yuan. However, the highlight of the Kekezhuo M1 projection mobile phone is the combination of the two. In this way, the size is almost the smallest in the micro investment, and the portability is better. And don't forget that it is also a micro projection with 4G Internet access function, which can be used everywhere. Of course, if Coco Zhuoke can be more careful about the mobile phone configuration, put the mainstream configuration of the current Android camp, and adapt the higher version of Android system on the system, then the M1 projection mobile phone may be more easily accepted by the market.
