Rebirth: I carry a desktop computer inside me

By the end of December, an ISP chip had been designed and taped out.

Customized accessories have also arrived in the laboratory.

On December 24, under the guidance of skilled structural engineers, several engineering prototypes were quickly assembled.

Because it is a rush engineering prototype, the entire appearance design is still relatively rough, but the internal hardware of the mobile phone is first put in.

Processor: Haise's K2V3+ self-developed Maple Fire ISP chip F211.

Running memory: 2GB, choose the Hynix brand.

Body capacity: 16G, general miscellaneous.

Cameras: front 2 million + rear 8 million cameras, from Soni.

Battery capacity: 2600mAh, with Yadi battery.

Screen: 5.3 inches, is Xiapu's screen, glass is selected for Kangning Gorilla II screen, resolution of 1920*1080.

System: Based on Android 4.2.2 version of FIUI 1.0.

This system is not yet complete, it is currently a beta version, and it has been burned into ROM. Most of the applications inside are native to Andao.

The mobile phone frequency is limited by Jiang Cheng, and the quad-core is 1.6G + 1.4G.

Usual applications mainly use small cores and large cores.

When it comes to video and gaming, large cores are the mainstay, and ISP chips and small cores are assisted.

However, these are still only preliminary designs and simulations by Jiang Cheng, and whether they can realize their own ideas or do not need actual verification.

Pressing the boot button, Jiang Cheng saw the screen light up.

No wonder many copycat manufacturers have to make mobile phones, purchase some accessories, plus MediaTek's complete motherboard package, just do it.

The Andowment system is also free and open source.

In the middle of the screen, the first thing that lights up is the maple fire logo.

After a while, I entered the system desktop.

The first boot guidance in front was all native to the security desk system, and Jiang Cheng didn't care.

Mo Tianqing, Guo Xiaoming and a few others also turned on the prototype No. 2-5.

"Our mobile phone interactive language, I don't know if users will be willing to learn?" Chen Xiao was a little worried.

When entering the desktop, a reminder pops up to choose what kind of interaction method to choose.

What is suggested is a full-screen gesture, which is the same interaction that Jiang Cheng used in his previous life, sliding up to return to the desktop, swiping up to hover, and summoning tasks; You can go back to the previous page left or right.

In addition, you can choose the boss three keys, but they are all virtual keys, not physical keys, choose this time, there will be a bar at the top, and the screen display area will be less.

Jiang Cheng smiled and said, "You guys will know if you try it first." "

As I spoke, I used it skillfully.

That's a good interaction.

However, when Jiang Cheng used it, he obviously felt that the interaction was not smooth enough, and when he slid left and right, he was a little knocked.

Mo Tianqing was not used to it at first, but after trying a few more times, he felt, "This is good, it can also save space for the screen, with these few gestures, you can realize the function of those three keys!"

Several others also said that if users are used to it, this interaction must be better.

After entering the main desktop, these UIs have been reviewed and drawn by Jiang Cheng, and many of them are drawn by him himself.

With the theme of flat icons, the wallpaper is a snowy mountain reflecting the rising sun, and the autumn maples by the lake below are quite interesting.

"I feel that our theme is very refreshing, and the icons are also beautiful."

"Yes, it's very attractive."

Next is to download the software.

The current version is still a test, there is no app store, and it must be downloaded through the browser.

I also let everyone test the wifi connection and other functions.

The initial experience was very good.

But then, there are still a lot of tests to do.

Key test, it is necessary to simulate several commonly used gestures to continuously test the sensitivity of the screen and interaction;

Battery test, which needs to test battery usage in standby, video, games, etc.

Although the first engineering prototypes came out, there are still many things waiting for them.

There are still many problems in the test, including bugs in the system, errors in interaction logic, and obvious lag when frequently mobilizing large and small cores.

But there is also good news.

The signal is indeed very good, reaching the forefront level of China.

It is the Warwick mobile phone signal that specializes in communication, and the signal strength is not higher than Jiang Cheng's mobile phone.

The ISP chip has a certain effect, and when gaming, it is obvious that the lag phenomenon is reduced, although the frame rate is not particularly high, but the performance is still stable, and the temperature control is not bad.

Immediately afterwards, Jiang Cheng instructed the R&D team to continue to improve and optimize the problem, and at the same time arrange the declaration and filing, apply for the network access license, and so on.

The press conference is tentatively scheduled for the end of February after the lunar year.

Of course, Jiang Cheng does not preside, but Mo Tianqing presides and introduces it.

The prototype of the No. 1 project, Jiang Cheng stayed in the company, let people specially collect and preserve.

This is something that can be displayed in the company's history!

I took another one, ready to try it as a user, and see if there are other problems, so that there will be no big problems after the official OEM.

The new machine is called Maple Fire Kind 1. It means friendly and considerate.

Appearance color, preliminary champagne gold, Xuan Suqing, Hanyu white, ink jade black.

Color design Jiang Cheng himself also spent his own thoughts, just to sell this mobile phone better.

When you play for the first time, you always have to make some money.

As for how much the price is set, Jiang Cheng calculates the cost and profit, and the 20% profit margin must always be achieved, right?

Pricing a mobile phone is a science.

When the brand value of mobile phones does not rise, it is easy to plant a head if the price is too high.

You don't see, Rebs's rice mobile phone in order to rush to the high-end, how many ways to think, but still did not rush successfully.

And what he said that his hardware profit is only 5%, that is even more nonsense.

Unless it is those thousand-dollar machines, in order to grab the market, a vigorous low price; Or when it first went public, the cost was not diluted, and the profit would be less.

But with procurement costs falling, and some expense sharing, margins will rise.

According to relevant insiders, the price of 1999 yuan of rice mobile phone has at least 20% of the profit, that is, a mobile phone, he can earn at least 400 yuan.

The hardware cost of Jiangcheng's mobile phone (plus the cost of several types of self-developed chips) is expected to be 800 to 900 yuan.

In the hardware cost, the majority is K2V3 chips, screens, RAM + ROM memory, cameras, etc.

Of course, mobile phones cannot only have hardware costs, software costs, assembly costs, packaging boxes and power accessories and other costs, which cost at least 300 yuan.

If you add channel costs, then at least 200 yuan must be reserved for offline dealers.

For these reasons, Jiang Cheng's price for the new mobile phone Maple Fire Kind 1 is 1699 yuan.

This price is considered to be below the middle level in the current mobile phone market.

This year, the sub-brand of rice mobile phones, Black Rice, was established, focusing on the market in the thousand-yuan machine.

Many people are buying.

But Jiang Cheng said he was indifferent to the phone.

Subsequently, the decline in procurement costs, and the current focus on online channels, Jiang Cheng reserved 200 to 300 room for downgrading.

After using it for a few days, Jiang Cheng gave feedback on some problems that needed to be optimized for experience, so that the R&D team could improve it as soon as possible.

His first mobile phone, even if it is a mid-range device, should be done more perfectly.
