Android has long been the world's largest and most user-friendly mobile operating system, but it is far from the best in the world. Everyone can easily mention some bad experiences that have been experienced, such as mobile phone, black screen, power is not enough, advertising pop-ups can not be banned themselves! What are the reasons for this? What is the Android native design?

Android origin
Android is an open source operating system based on Linux and JAVA, mainly used in portable devices. More people in mainland China use "Android." The Android operating system was originally developed by Andy Rubin. After being acquired by Google, it was led and developed by Google and the Open Handset Alliance, mainly supporting mobile phones and tablets.
The Android platform has several obvious advantages: The Android development platform allows any mobile terminal manufacturer to join the Android Alliance. The rich software resources and eclectic hardware construction are easily favored by consumers and operators; The shackles of merchants make it easier for users to access the Internet; the Android platform provides developers with a very broad and free development environment, not subject to too many constraints; rich applications from search giants to comprehensive Internet penetration, Google Services such as maps, emails, and search have become important links between users and the Internet, and Android platform phones will seamlessly integrate these excellent Google services.
Mobile phone
From a technical point of view, Caton has three main reasons: Android application uses Java language, it consumes more hardware resources than iOS Object C; Android devices are too scattered, at least half of them are middle and low-end models; Android has no foreground process Increase the priority, too much background to easily seize more resources.
Although "born to win", but after several years of hard work, now the latest Android devices have rarely had a problem with Caton. Let's see how this problem has been improved.
The early Android version (v1.5+) had no process management. Whenever there were several applications open, everyone would use third-party tools such as atk to kill the background.
Android 2.3 has joined the process management, and finally can use the system settings to close the application, but only one level. At this time, many tool applications have supported one-click memory.
The "Butter Plan" of Android 4.1-4.4 and subsequent improvements have greatly optimized the small memory devices, and the desktop switching effect is gorgeous and smooth. This is also due to the acceleration of hardware changes. The time from single-core to dual-core and quad-core upgrades was completed in more than one year in 2013.
Android 4.4 has developed a new application running environment ART. After switching to ART, the application opens and switches very smoothly, which is comparable to the desktop switching effect after the “Butter Planâ€. However, ART requires developers to be compatible with applications, and most mainstream applications have made compatibility updates.
In fact, in 2013-14, the performance of the hardware has been able to make Android smooth enough, but we can still hear some Karton complaints. The reason is that WeChat (the game is expected, but not so complaining), if your WeChat friends and group are slightly more, it will gradually consume the memory of this device, and the cleaning tools can only ease the situation. WeChat has become the reason why many people upgrade their equipment now.
Not enough power
Mobile devices don’t have enough power, but Android is especially noticeable. It's easy to compare, the Android phone usage time of 3000mAh battery is similar to that of 1500mAh iPhone, sometimes it is not as good.
However, this has been a great improvement, because the current Android system is much richer than before, and it can still drive Wi-Fi, Bluetooth and GPS. Android power consumption optimization is divided into two aspects: hardware, software. The hardware side was optimized around 2013. The difference between “Wi-Fi†and “Wi-Fi-free†was more than 10%, but the difference is not big now.
The software side is mainly after the standby, the background application is still working, such as networking to check for new messages. All news feeds on iOS use Apple's official push service. Due to Google's GCM is not mandatory and not available in China, everyone uses their own or partner's push service. For example, the same three applications receive messages, Apple's last push is completed, and Android has to push three times. Some vendors have added "alignment wakeup" in ROM to allow Android to push once, but it is considered to be bypassed.
The proliferation of push services has become the biggest source of power consumption for Android. At this time, "one-click clear background" has a new meaning. From the beginning of the easing of the card to the current power saving, the background is clear, it will be a hundred.
third-party software
For example, advertising pop-ups, abuse of permissions, application cache files, these allow third-party security applications to have room to play, LBE security masters, 360 mobile guards, Tencent mobile butler based on this. The advertising pop-up plug-in has been more popular in the past few years, and the notification bar of the mobile phone is almost all of this information. There have also been some wonderful things. The ad plugin in an app doesn't start normally, but when WeChat starts, it advertises, letting the user think that WeChat is popping up. Later, almost the scale of the ad plug-in was identified. Due to the poor performance, the current ad plug-in converges a lot, only for user information collection and fixed display.
This part is no longer Android conquering hardware, but a battle between mobile security companies and advertising companies.
Application permission
Permission abuse is also terrible. The earliest version of WeChat will automatically upload the user's address book, which is a typical example. The current response is to use rights management software, and most security applications have integration.
Cache aspect
On the one hand, the cache is too small to meet the application conditions of some applications; on the other hand, users do not often clean up system garbage and application cache. System garbage and application cache seem to be small, but they use the three-party cleaning software such as Cheetah Cleanup Master or 360 Mobile Security and the cache cleaning plug-in that comes with the machine to know that they account for a large part of the storage space.
to sum up
In terms of Android developers, it is not too picky; in the case of mobile phone manufacturers, under the premise of minimizing costs, driving manufacturers to launch different configurations of mobile phones, also provides users with a variety of options, while bringing Not the same experience.
The mechanical Buzzer uses a magnet to move a reed up and down quickly to emit a lower-pitch buzz! It's quieter than the piezoelectric buzzer but uses more power, so you the terminals will have to be closer to the battery packs. To use them, you'll need to match the wire colors to the wires from the battery pack.
