Mobile OEM advertising—placement of branded content, apps, and promotions directly through device manufacturers—has emerged as one of the most powerful and underutilized channels in the 2026 mobile marketing landscape. With global smartphone shipments stabilizing at 1.2–1.3 billion units annually and manufacturers like Samsung, Xiaomi, OPPO, and vivo commanding massive pre-installed audiences, OEM partnerships now deliver access to users at the moment of highest receptivity: device activation and first-use.
In an era where traditional app install campaigns face rising costs and diminishing returns, OEM advertising offers unmatched scale, zero-acquisition friction, and persistent visibility. This SEO-optimized article explores the strategic ascent of mobile OEM advertising, its unique advantages in a privacy-constrained world, and its growing influence on global mobile marketing performance.
Defining Mobile OEM Advertising
Mobile OEM (Original Equipment Manufacturer) advertising encompasses promotional placements integrated by device makers themselves. These include pre-installed apps, lock-screen content, system notifications, branded widgets, and default browser bookmarks. Unlike third-party ad networks, OEM inventory is baked into the device firmware or system UI, ensuring exposure that cannot be blocked by ad blockers or easily uninstalled without technical expertise.
In 2026, major manufacturers operate sophisticated monetization divisions—Samsung Ads, Xiaomi GetApps, OPPO Advertising—selling premium inventory to brands seeking guaranteed reach. These placements appear during out-of-box experience (OOBE), home screen setup, or as persistent system features, creating touchpoints that traditional UA campaigns struggle to replicate.
The Strategic Shift Toward OEM Channels
The surge in OEM advertising reflects fundamental changes in mobile user acquisition economics. Average cost-per-install (CPI) on major networks has risen 40–60% since 2023 due to privacy restrictions (IDFA deprecation, Google’s Privacy Sandbox) and platform fees. Meanwhile, OEM channels offer fixed-cost or revenue-share models with near-zero marginal acquisition expense.
Manufacturers control hundreds of millions of active devices—Samsung alone exceeds 1 billion—and update system apps remotely, extending campaign lifespans indefinitely. This persistence contrasts sharply with paid install campaigns, where users often delete apps within weeks. Brands leveraging OEM placements report 3–5× higher long-term retention compared to organic or paid installs, as pre-installed apps benefit from default status and system integration.
Unmatched Advantages in a Privacy-First World
Privacy regulations have inadvertently elevated OEM advertising’s value. While third-party tracking faces increasing restrictions, manufacturers retain first-party relationships with device owners through system accounts and telemetry. This enables contextual targeting—language, region, device model—without relying on cross-app identifiers.
OEM inventory also sidesteps user-initiated ad blocking. System-level placements appear as native features, achieving viewability rates approaching 100%. In emerging markets where Android dominates (90%+ share in Africa, Southeast Asia, Latin America), OEM channels deliver scale that Western-focused networks cannot match. Xiaomi and vivo devices, for instance, ship with localized content partnerships that drive immediate relevance for regional brands.

Creative and Experiential Superiority
OEM advertising unlocks creative possibilities unavailable elsewhere. Full-screen onboarding flows, branded system themes, and lock-screen magazines allow immersive storytelling from the first moment of device ownership. Manufacturers increasingly support rich media—video wallpapers, interactive widgets, and AR try-on experiences—embedded at the OS level.
These formats benefit from guaranteed performance: no load-time delays, no competing ads, and seamless integration with device hardware. A beauty brand partnering with OPPO can deliver an AR makeup filter as part of the camera app’s default effects, achieving millions of organic uses without additional promotion.
Integration with Broader Mobile Strategies
OEM advertising complements rather than competes with traditional channels. Brands use OEM placements as top-of-funnel awareness drivers, then retarget users through standard networks with matched identifiers. The combination yields 2–4× higher overall campaign efficiency.
In gaming, OEM partnerships with manufacturers like Samsung secure featured placements in Game Launcher hubs, driving installs at fractions of traditional CPI costs. E-commerce brands leverage pre-installed shopping aggregators (common on Xiaomi and realme devices) to establish default purchase pathways from day one.
Challenges and Considerations
Despite its advantages, OEM advertising presents hurdles. Inventory is finite and controlled by a handful of manufacturers, creating high competition for premium slots. Negotiations often require significant upfront commitments and long-term partnerships.
Creative constraints exist—ads must align with manufacturer guidelines to avoid user backlash or regulatory scrutiny. Overly aggressive placements risk damaging device maker reputations, leading to conservative approval processes.
Measurement also differs from standard campaigns. While manufacturers provide robust reporting (impressions, engagements, downstream installs), cross-attribution remains complex without universal identifiers.
The Future Trajectory of OEM Advertising
Looking ahead to 2027–2028, OEM advertising is poised for continued expansion. Foldable and wearable device categories will open new placement opportunities, while AI-driven content recommendation engines inside system apps will enable hyper-personalized brand integrations.
Emerging manufacturers in Africa and Southeast Asia are building their own ad platforms, democratizing access for local brands. As privacy pressures intensify, OEM channels—rooted in first-party device relationships—will increasingly become the most reliable path to guaranteed, compliant reach.
Overview
Mobile OEM advertising represents a paradigm shift in 2026 mobile marketing: from chasing users across fragmented channels to meeting them at the point of device ownership with persistent, trusted placements. Its combination of scale, performance, creative freedom, and privacy resilience positions it as the premium inventory class for brands pursuing sustainable growth. In an era defined by attention scarcity and acquisition fatigue, OEM partnerships offer the rare advantage of being there from the very first swipe—establishing presence before competitors even enter the consideration set.
