A brand’s credibility lies in the quality, durability and innovation of its products, especially for ever-evolving smartphones. Oppo is one such brand that has taken product quality as a cornerstone of its sustainable, long-term development. The recent launch of Reno 7 series that offers an entirely novel experience and the company’s first foldable phone Find N shows how Oppo is always in the pursuit of offering something new with its device. Rollable is another concept Oppo is exploring, in terms of innovation and investment in the future of technology. Tasleem Arif, VP and R&D Head, Oppo India, shares in-depth insights on the importance of quality and testing and how smartphone brands can bring innovation to devices without compromising on quality, in an email interaction with Ramesh Kumar Raja. Excerpts: Can you please tell us about the various quality tests that the smartphones go through to ensure maximum durability? Smartphones are indispensable to most of our daily life, so they need to be capable of withstanding the wide variety of situations. To make sure Oppo’s devices can hold up to just about any challenge, the QE Reliability Lab is tasked with testing products against the strictest quality standards at all stages. Oppo products can only reach consumers if they have successfully passed this rigorous journey of 150 tests, which includes drop test, sandpaper test, environmental tests, mechanical stress tests, durability tests, performance tests and many more such as tumble test, waterproofing test, rain test, humid test, salt spray test, ESD (Electrostatic Discharge) test, temperature test, press test, USB plugging & bending test, Audio Test Lab, amongst others. For instance, the USB input is tested by swinging the device from an attached USB cable 5,000 to 10,000 times using a 3kg force. With Oppo’s Environmental Work Test, this involves storing the phone at a low temperature, from as low as -40°C, to warm conditions at 75°C for 7 days (168 hours)– more than double the industry standard of 3 days (72 hours). The phone is also tested at intense humidity and temperature (95% humidity at 65°C) for 14 days (336 hours), which is also more than double the industry standard of 3 days (72 hours). What is Oppo’s innovative approach to product testing? Stability and reliability form the core foundations of an enjoyable smartphone experience. Aligned with our brand vision of Technology for Mankind, Kindness for the World, we have always taken product quality as a foundation of our sustainable, long-term development. Oppo tests its devices against stricter standards than most companies in the industry. Our drop is set at a height of 1 meter, 25% higher than the industry standard of 0.8 meters. Oppo phones are dropped 28,000 times from a height of bed/table – which is considerably more than the 5,000-10,000 times typically adopted in the industry. Just like the drop tests, Oppo’s waterproofing test also undergoes extreme situations. While the common industry standard for water resistance is at IPX2, Oppo’s Rain Test adopts the IPX4 standard, simulating a “heavy” rainfall of 10±0.5 L/min. We are committed to representing quality without compromise, and all our products result from tireless efforts towards quality testing. Oppo’s focus is to empower users with premium devices that can endure bumps and spills and even exceed users’ durability requirements. Oppo Reno series makes a noise every time with its launch. What is Oppo’s focus on the quality of the device and how Reno 7 series is pushing all boundaries? The Oppo Reno series has been constantly refreshing its appearance with every generation, offering a state-of-the art experience each time with Oppo Glow process finish. Also, the use of LDI (Laser Direct Imaging) technology on Oppo Reno 7 Pro 5G is the first time that Oppo itself has used laser engraving technology to perform additional precision processing on top of the Oppo Glow layer, making it more durable. With the latest Reno 7 series, along with the innovative look, Oppo is also setting new benchmarks for quality. To deliver industry-leading reliability experience, our Reno 7 series smartphones is subjected to one of the most vigorous testing processes in the industry that are designed to evaluate how the devices will perform during normal day-to-day use.

For instance, to test the water resistance, the Reno 7 series was tested underwater at a depth of 20 centimetres for 30 seconds. To test the phone’s USB and headphone inputs, USB cables and headphone jacks were inserted 10,000 times each, at varying angles. Further, Oppo OTA Lab conducts rigorous tests on the radiation efficiency of the phone’s antennas and on the various network bands including 5G to ensure its seamless trouble-free operability, anywhere in the country. “With the latest Reno 7 series, along with the innovative look, Oppo is also setting new benchmarks for quality. To deliver industry-leading reliability experience, our Reno 7 series smartphones is subjected to one of the most vigorous testing processes in the industry that are designed to evaluate how the devices will perform during normal day-to-day use” How is Reno series enhancing the iconic Oppo Glow with LDI innovation? Oppo’s exclusive Oppo Glow glass manufacturing process has been a central part of the overall design of the Reno series. The Reno 7 series has set a new milestone in smartphone aesthetics with proprietary Oppo Glow design that incorporates aircraft-grade Laser Direct Imaging (LDI) technology. It is the first time LDI has ever been applied to the exterior design of a mobile device. It is also the first time that Oppo itself has used laser engraving technology to perform additional precision processing on top of the Oppo Glow layer. The Process Lab team of over 100 experts challenged the limits of precision for the LDI process, designing their own laser etching patterns as they repeatedly enhanced the textured effect. Over 3,000 test sample adjustments were made to the thickness, angle, and pattern of the micro-rasters until the process was capable of creating the articulate visual and textural quality envisioned by Oppo on the Reno 7 series. LDI is used to design PCBs in the aviation industry. Our engineers worked for three years to repurpose the "aircraft-grade" LDI, which is used to create 1.2 million micro-etchings with a width of 20 microns across the surface of the back cover. This creates a visual and textural illusion of shooting stars streaming across the device that shine and fade into the black galaxy as the phone is held in the hand. In addition to its shimmering visual effect, the use of LDI also adds a physical texture to the surface of the cover, creating a sensation like ultra-fine strands of hair flowing in the wake of the meteor shower. This refreshing visual, tactile, and textural sensation is a completely new experience for smartphone users. Tell us more about the new-generation RGBW sensor in Reno 7? RGBW technology has become one of the main approaches in the field of image technology in recent years. However, due to problems such as manufacturing process, the limited computational power of the sensors, and signal crosstalk, images taken using traditional RGBW pixel array sensors are often prone to chromatic aberrations and false colours. Therefore, RGBW sensors have never been considered the mainstream option for enhancing sensor sensitivity. Oppo never stopped and continued their research in sensor technologies to find the best way to increase light sensitivity. As a result of its continued efforts, Oppo has collaborated with Sony and co-designed industry’s first exclusive 32MP IMX709 selfie camera sensor and 50MP IMX766 flagship rear camera sensor for Reno 7. The IMX709 is a customized RGBW (red, blue, green, white) front image sensor that can capture crisper and more evenly exposed photos and videos; it is 60% more sensitive to light and reduces noise by 30% when compared to traditional RGB sensors. This makes it one of the best cameras to shoot with, when indoors or in low-light settings. Furthermore, Oppo has optimized the algorithms to reconstruct the Bokeh light spot in a way that is similar to DSLR cameras. “Oppo has collaborated with Sony and co-designed industry’s first exclusive 32MP IMX709 selfie camera sensor and 50MP IMX766 flagship rear camera sensor for Reno 7.
