As a lion who likes tossing, I usually like to delve into some digital products.
The protagonist to be introduced this time is a home micro-projector with a meter:
In fact, this product should not be unfamiliar to you Zhang Aunt’s value-friends, because it had been held in Aunt Zhang’s past two months ago:
At that time, you valued friends also gave a very good report:
such as:
Another example:
There is this:
And this:
However, it is a pity that due to the time limit of all the measures, you did not dig deeper into the function of this product.
I think this machine is very good, so I also started one. As a siege lion and GEEK, of course, can not be satisfied with such simple basic functions. So, this article is to share with you some of the in-depth use of this mango cake (the author later found through software, code-named Z4 Mango, later called it Z4 Mango), use now In popular terms, it means "playing bad" screenless TV.
Look at some simple hardware tips:
1. Regarding sound effects, the Z4X uses a Harman Kardon jellyfish speaker, and sound quality is naturally not a problem. But the Z4 Mango's speakers are not that great, and you want to make up for this by connecting a USB-powered active speaker, which expands the channel to 2.0 and greatly improves sound performance:
The figure is used in this product:
A lot of similar products on the market, generally can get about 50 yuan.
2. Regarding the HDMI input source, HTPC is naturally one of the best choices.
You can watch web pages, or videos on your computer at the same time. The above picture shows the ASUS minicomputer:
Of course, in fact, the Z4 Mango is already an extremely powerful smart device for the Android platform. Therefore, it is actually too luxurious to have such an HTPC.
3. Z4 Mango supports USB OTG (On The Go) function, so you can attach an external USB flash drive or removable hard disk, and read the data:
The above figure uses this mobile hard disk:
Having said the hardware, let's look at the software:
Through research, it can be found that Z4 Mango is actually an Android device. The Mstar quad-core processor based on the Cortex A7 architecture has a maximum clock speed of 1.15 GHz, which is slightly weaker than the configuration of smart phones, but it is also sufficient:
Running memory RAM is 1GB and ROM is 4GB:
The output resolution is 720P and the GPU is the Mali 450 MP1. This GPU is also weaker than the mainstream smartphones, but playing video is sufficient:
Android 4.4.2 based system:
The wireless network card comes from BroadCom Broadcom, and the remote controller is Changhong's Air Mouse solution:
Since this is an Android device that can support USB OTG, we can naturally install many Android applications on it.
There are two main installation methods:
Install via APK file in USB stick or removable hard disk
Installed through a variety of TV box application markets, such as when the Bay Market
The author first paid attention to the security issue. At present, the security software on the TV box is extremely scarce, and only a few softwares have not been updated for a long time. The security software on the phone is very rich, and it has been updated, and keep the latest virus database. Therefore, I thought of installing some security software directly on the phone to Z4 Mango:
Because USB OTG is supported, the operation of the keys is accomplished through an external USB mouse. After scanning, many problems were discovered:
Using Cheetah Security Master, discovered 7 Android vulnerabilities:
Are all high-risk vulnerabilities that can get root privileges:
Why must we fix these vulnerabilities? Because, as long as the hackers into the Wi-Fi network in your home, you can find these vulnerabilities of this device, in order to obtain root privileges of Z4 Mango. As a result, he can damage the system and prevent you from booting. The most important thing is to look at all the files on your mobile hard disk or USB stick that you have connected to Z4 Mango, violating your privacy. Therefore, it is very important to make up for loopholes in the system.
Then, install a 360 mobile phone guard to scan:
No virus:
Since the cheetah has already processed, the 360 ​​display system is in good condition:
After loading 360 mobile phone guards, the upper right corner of the system menu, out of a small memory consumption of bubbles:
There are also some utility software, such as the ES file manager, which is also very convenient to use with an external mouse:
If you like, you can even use an external mouse to play racing games. Of course, this kind of user experience is not good.
After installing the TV live application, all TV programs can watch live and look back, which is very convenient:
After installing the browser, you can see the video in the webpage:
Finally, if you are not satisfied with the default desktop, you can install a third-party desktop, giving you a fresh feeling:
Compared to the default desktop, what feels like a new look?
At this point, the author just introduced some of Mango's more superficial playing skills. In fact, after this step, you can completely get the machine's root privileges, and then you can actually change the content of more. Such as system fonts, such as boot screens and so on. Of course, this may damage the warranty of the machine, so I decided to wait until the machine is over and then try again. We must share it with our friends! Everyone in the process of using, what skills, and welcome to discuss and discuss! Thank you!
