After a sluggish initial October debut in India caused by steep import pricing, shipments of Apple's iPhone 6s and 6s Plus surged dramatically in November 2015, driven by aggressive Diwali trade-in promotions and expanded distribution partnerships. Import Surge Following Festive Buybacks According to import data from Cybex Exim, Apple imported 562,500 iPhones into India between October 1 and November 15, with the new 6s series accounting for nearly 74 percent of the total. In its first month alone, Apple shipped over 413,500 units of the 6s lineup — almost matching its entire sales volume from the corresponding quarter of 2014. The Buyback Solution The turning point occurred when Apple and its retail partners introduced structured buyback schemes offering trade-in discounts of up to Rs 34,000 just ahead of the Diwali shopping season. Counterpoint Research analyst Tarun Pathak noted that Apple's strategy focused on lowering the barrier to entry for its ecosystem, capturing a...

In November 2015, a Finnish startup led by entrepreneur Kristoffer Lawson unveiled Solu, an eccentric pocket computer encased in sustainable wood with an edge-to-edge square touchscreen. Solu was designed not as a phone replacement, but as an entirely new paradigm for desktop computing and collaboration.

In late October 2015, patent filings and supply chain leaks revealed that Xiaomi was actively developing a pressure-sensitive touchscreen feature for future flagship smartphones, directly inspired by Apple's 3D Touch technology on the iPhone 6s. The Industry Rush for Force Sensing Following Apple's introduction of "Peek and Pop" pressure gestures, Android manufacturers including Xiaomi, Huawei, and Meizu scrambled to explore force-sensitive hardware panels. The goal was to provide secondary contextual menus when users pressed firmly on home-screen icons or content previews. Why Force Touch Eventually Faded While the hardware was technically capable, pressure-sensitive displays faced persistent user adoption hurdles on Android: third-party app developers were reluctant to build custom workflows for non-standard hardware. In subsequent years, both Android and iOS phased out hardware-level force sensors in favor of long-press haptic software interactions.

When Apple launched the iPhone 6s in late 2015, the company made no marketing claims about water resistance. Yet early teardowns by repair authority iFixit revealed that Apple had quietly implemented substantial internal engineering safeguards against liquid ingress. The Mystery Display Gasket Upon disassembling the iPhone 6s, technicians discovered a custom adhesive gasket lining the entire perimeter between the display assembly and the outer chassis. Apple had widened the internal lip of the aluminum housing by 0.3 mm compared to the iPhone 6 specifically to accommodate this protective seal. Board-Level Conformal Coating Rather than attempting to seal the entire external casing, Apple focused on protecting delicate logic board circuitry. Every critical logic board connector was encased in a soft, silicone-like hydrophobic barrier that shielded electrical contacts from moisture-induced short circuits and corrosion. This quiet engineering evolution paved the way for official IP67 w...

In early October 2015, Apple's premium retail partners across India — including iNvent and other authorised resellers — commenced pre-orders for the iPhone 6s and iPhone 6s Plus ahead of an official launch date on October 16. Customers placed advance reservation deposits of Rs 10,000 to secure their units on launch day. Pricing Realities in the Indian Market The iPhone 6s debuted with launch pricing starting at approximately Rs 62,000 for the base 16 GB model, while top-tier 128 GB iPhone 6s Plus configurations reached upwards of Rs 92,000. Due to currency exchange rates, import duties, and local taxes, Indian retail prices were approximately Rs 14,000 to Rs 16,000 higher than equivalent launch prices in the United States and the Middle East. Key Architectural Upgrades Despite the high price barrier, the 6s series generated substantial interest thanks to the A9 chipset, 3D Touch pressure-sensitive displays, upgraded 12 MP cameras capable of 4K video recording, and a fortified 7...

The device ran standard Android with full Google Play Store support, supplemented by BlackBerry's proprietary DTEK security suite and enterprise productivity tools. A Historic Platform Pivot For over a decade, BlackBerry had relied exclusively on its proprietary operating systems. Transitioning to Android was a pragmatic acknowledgment that the app ecosystem deficit on BlackBerry 10 had become insurmountable. The Priv marked a pivotal turning point as the company shifte...

Shortly after the public rollout of iOS 9 in September 2015, independent security researcher Jose Rodriguez uncovered a significant lock screen bypass flaw that allowed physical access to a user's contacts and photo library without entering the device passcode. How the Vulnerability Operated The exploit relied on a flaw in how the lock screen interacted with Siri and the Clock app. By entering incorrect passcodes and invoking Siri at a specific timing interval, an attacker could trigger accessibility and search features that revealed the device's Address Book. From the contacts interface, an unauthorised user could browse photos, email addresses, and phone numbers without authenticating. Mitigation and Patching Security analysts advised users to temporarily disable lock-screen Siri access in device settings while Apple developed a software update. The incident underscored an ongoing challenge in mobile security design: balancing lock-screen voice convenience with strict dat...

In late September 2015, Mozilla released Firefox 41 for desktop and Android, introducing an ambitious experiment: an integrated communication tool dubbed Firefox Hello. Built directly into the browser, Hello allowed users to make voice and video calls, send instant messages, and share screens without installing third-party plugins or registering a separate account. How Firefox Hello Worked First introduced in Firefox 34 and expanded significantly in version 41, Hello relied on open WebRTC standards. To start a call or collaboration session, a host simply generated a shareable link and sent it to a friend or colleague. The recipient could join directly through any WebRTC-compatible browser, enabling quick document co-browsing and casual conversations. The Retrospective View While the concept of account-free, friction-free browser calling was technically impressive, users ultimately gravitated toward dedicated ecosystems like WhatsApp, Skype, and Google Hangouts.
