SHENZHEN, CHINA – Media OutReach Newswire – February 23, 2024 – Over the past ten years, OPPO has strived to perfect the balance between fast responsiveness, rock-solid stability, and silky smoothness with each iteration of ColorOS. On the recently launched ColorOS 14, OPPO has included a series of enhanced features designed to allow users to enjoy a real sense of fluidity and efficiency by providing consistent and smooth operations in all types of applications and scenarios .
By constantly finding new ways to combine the best hardware with the most comprehensive and in-depth optimization of the underlying software, OPPO has elevated the concept of smoothness, and even the entire perception of performance on Android smartphones, to ensure a seamless user experience in all situations. .
“Visible” and “invisible” softness
One of OPPO’s first advancements in the ultimate seamless user experience came with the release of UI First in early 2020. By prioritizing active apps, UI First prevents background apps from overconsuming system resources, resulting in lower overall performance. The result is a significant reduction in noticeable lag and an improvement in “visible smoothness”.
However, as computing resources were directed toward supporting active applications, applications running in the background were starved of resources and effectively killed. This in turn led to delays when switching between these applications. Meanwhile, the widespread adoption of 5G has increased the consumption of high-density media, entering the so-called “rich media” era, has put additional processing pressure on the system. To address these “invisible” fluidity issues, OPPO has started optimizing ColorOS for better temperature control, stable battery life, and a more continuous and uninterrupted experience.
OPPO’s chip engineers have conducted huge volumes of in-depth analysis on the distribution of each task’s computing power across different processing units on the chip. The company then established mathematical models to predict performance and energy consumption and optimize the distribution of computing power for each task. ensure better battery life without sacrificing performance capabilities.
At the same time, OPPO used improved memory compression technology to save more memory space for users, as well as breakpoint playback technology to ensure a more continuous and uninterrupted experience. Now, on ColorOS 14, the latest version of the system, upgraded technologies in the operating system’s Trinity Engine allow the phone to run up to 28 apps on the backend for up to 72 hours.
These innovations allow ColorOS to get the most out of any smartphone hardware and deliver the best results in traditional metrics used to measure smooth performance, such as app launch speeds, frame rates games, etc. With such hardware planning capabilities, ColorOS now consistently ranks among the highest performers in major industry benchmarks.
More human, more coherent
As OPPO engineers continued to push the boundaries of smoothness and ColorOS received increasing recognition from technology authorities with its top benchmark scores, the team gradually realized that high performance and ultimate speed were not do not necessarily translate into a more comfortable and “smoother” user experience. in all scenarios.
“As a software developer, my instinct was to always do everything as quickly as possible. It’s easy for us to get into the habit of striving for the best results from a numbers perspective,” said Hansheng Hong, Director of Software Technology Planning, OPPO.
“For example, we are able to double the current speed of our animations, but when the user actually sees them, they appear too abrupt. Realizing this completely changed my perspective and taught me that there was no point in competing on data alone. ”
The all-new Aquamorphic effects in ColorOS 14 show how this idea has been put into practice. Contrary to what one might expect, the animations for these new effects have actually been optimized by reducing the speed from 380 milliseconds to a more user-friendly 750 milliseconds. By refining the logic of dynamic effects in ColorOS 14, every interaction has become more intuitive and fluid.
This is just one example of how OPPO has introduced human factors analysis into operating system design. It is a discipline specializing in the study of human interaction with machines and environments in order to make machines or systems more adaptable to human physiological and psychological characteristics. Through human factors analysis, Hong learned that the human eye can only detect changes at intervals of about 100 to 150 milliseconds or more. If the changes happen in less than 100 milliseconds, most people simply can’t tell the difference. This means that, even if the hardware is capable of doing this, there is no reason to design system response times as low as 50 milliseconds.
At the same time, Hong also became aware of a concept in psychology known as “negative bias,” in which people tend to remember only specific negative moments, even if the overall experience is positive. For example, if you only experience a delay one time out of a hundred when you start an application, you are even more likely to remember that negative moment and perceive the overall experience as overall negative. This implies that it is stability and consistency, rather than occasional speedups, that determine the smoothness of the user experience.
In order to provide this consistently smooth level of experience throughout the lifespan of our mobile devices, OPPO has introduced human factors analysis into several aspects of ColorOS. One of the resulting decisions was to set the response speed of application launches to 135 milliseconds. Through millions of repeated tests, OPPO has also identified and resolved extremely unlikely consistency issues in areas such as touch feedback, software concurrency, input lag, and more. The result is a consistent response time in the range of 100 to 150 milliseconds for all aspects of the user interface, with no perceptible fluctuations.
Exploit the possibilities of AI-generated content
Looking to the future of smartphone and operating system experiences, the ColorOS team recognizes that the integration of AIGC (AI-generated content) is likely to place a high demand on the company’s resources. mobile system, covering everything from memory and processing capabilities to battery life. Currently, OPPO is exploring and experimenting with related capabilities, such as how to optimize memory usage and power management techniques to cope with such high demands.
The Trinity engine in ColorOS 14 exemplifies this forward-thinking approach with its advanced solutions to optimize system fluidity and stability through fine-tuned management and scheduling of computing resources, memory and storage at the microarchitecture instruction level .
The upgraded Trinity engine contains three core technologies: ROM Vitalization, RAM Vitalization, and CPU Vitalization. ROM Vitalization frees up more memory space by compressing application data and merging duplicate files to resolve performance degradation issues caused by long-term memory filling up. RAM Vitalization works by rebuilding Android’s underlying RAM mechanism and employing specialized techniques to accelerate app launch speeds and improve the level of smoothness when switching between apps. Finally, CPU Vitalization uses a sophisticated computing power model that can accurately plan energy resources while determining the best balance between performance and power consumption.
In addition to the Trinity Engine, OPPO’s Instant Bandwidth technology that will be included in the upcoming ColorOS 14 update is another example of how the memory management system has been rewritten to improve smoothness of operation . OPPO developed the technology more than 18 months before the release of Google Linux’s open source design by modifying more than 50,000 lines of code in the original kernel. With Instant Bandwidth technology, memory access performance is dynamically adjusted based on smartphone usage, enabling speeds up to 16x faster (i.e. from 4K to 64K during the transfer process from DDRAM to CPU). As the data transfer bandwidth increases, the loss of read data decreases significantly, which helps improve memory usage and reduce latency when using the phone.
By further deepening the synergy between hardware and software, ColorOS 14 provides users with an ultra-smooth experience in all scenarios, guaranteed to remain smooth for up to 48 months. Drawing on insights from over 600 million active monthly ColorOS users, OPPO continues to use its unique position to identify global user trends and unmet needs to further optimize the smooth and stable experience on OPPO devices.
