Apple's Subpoena Gambit Exposes iPhone Lock

Apple's Samsung Gambit Exposes the iPhone Switching Myth

The DOJ says Apple locks users in; Apple says switching is easy enough to subpoena Samsung for proof. The court filings reveal why the defense may backfire — and why interoperability, not market share, is the real battleground in the 2027 antitrust trial.

On April 7, 2026, Apple asked a federal judge in New Jersey to invoke the Hague Evidence Convention to compel Samsung Electronics Co., Ltd. in South Korea to hand over internal data on how consumers switch between iPhones and Android devices. The filing is Apple's attempt to prove that platform switching happens often enough to undermine the DOJ's monopoly-lock-in theory — but the nine-month delay before Apple even served Samsung, and the friction that switching still entails, reveal a defense built on a fragile premise. Apple's own discovery strategy concedes that switching is hard enough to require external evidence to demonstrate it occurs at all.

The subpoena that reveals the strategy

Apple's motion, filed in United States v. Apple Inc., No. 2:24-cv-04055 (D.N.J.), seeks "internal business reports, market analyses, and data regarding Samsung's smartphone, smartwatch, and app store businesses," including documents on "consumer switching to and from iPhone and Apple Watch" (Apple's Memorandum in Support of Motion for Letter of Request, Dkt. 413). Apple had already subpoenaed Samsung's US subsidiary, Samsung Electronics America, which objected on the grounds that the relevant documents reside solely with its Korean parent.

The Justice Department's opposition is scathing. According to the Plaintiffs' Response, Dkt. 425, "Apple has asked the Court to invoke the complex and time-consuming foreign judicial process under the Hague Convention" even though Samsung operates in the United States through a domestic subsidiary subject to normal federal discovery. The DOJ notes that discovery opened in June 2025 and Apple "immediately began serving subpoenas on third parties," yet waited until January 30, 2026 to serve Samsung America — then waited eight more weeks to file the Hague motion. The DOJ characterizes Samsung as "the principal purported victim of Apple's anticompetitive conduct" in the case, making the company's relevance apparent since the complaint was filed in March 2024.

The court's amended scheduling order, issued January 30, 2026, extended fact discovery through January 29, 2027, but maintained that "no fact discovery shall be issued or engaged in beyond that date, except upon application and for good cause shown" (Amended Scheduling Order, Dkt. 408). That leaves roughly nine months for the Hague process to execute — which the DOJ calls "not probable." The government takes no position on whether the court should grant the motion, but insists Apple alone should bear the risk if the evidence arrives too late.

What "easy switching" actually looks like

The DOJ's First Amended Complaint, Dkt. 51 lays out the lock-in theory with precision. It cites a 2010 email in which an Apple executive wrote to Steve Jobs that a Kindle ad showing a woman switching from iPhone to Android sent a message "that can't be missed is that it is easy to switch from iPhone to Android. Not fun to watch." Jobs's response: Apple would "force" developers to use its payment system to lock in users and developers. The complaint alleges Apple "impairs technologies that would facilitate switching to other smartphones" across five domains: super apps, cloud streaming, cross-platform messaging, smartwatches, and digital wallets.

The UK Competition and Markets Authority's own investigation corroborates the friction. In Appendix J: Barriers to Switching, the CMA found that "transferring data and managing subscriptions across devices may impose significant time and financial costs on switchers." The agency noted that Android APIs make information available to switching apps about installed apps, "whereas equivalent information is not available to switching apps on iOS." Apple told the CMA that multiple transfer apps make the process "seamless and easy" — but the CMA found that "there does not appear to be a mechanism through which a third-party switching app can reliably obtain data on which apps a user has installed on their iOS device."

A 2025 NBER working paper by Filip Milojević quantifies the social dimension. Using samples of US college students, the study shows that "green bubbles are widely stigmatized" and that iPhone users "have a significant willingness to pay to prevent their messages from appearing as green bubbles on other iPhones." When green bubbles were removed in the experiment, "respondents are substantially more likely to choose an Android over an iPhone." The paper concludes that Apple's internal emails confirm the company knew iMessage's blue-bubble exclusivity made "it more difficult for users to switch smartphones, thereby reinforcing its market power."

The EU has already forced the fix Apple says is unnecessary

While Apple argues in US court that switching is competitive, the European Union has concluded the opposite and is mandating change. A May 2026 European Commission factsheet confirms that "Apple and Google have been working on a cross-OS data transfer solution that allows users to easily move all their data when switching between an iPhone and an Android phone." The Commission notes that "currently, users who want to switch device makers face significant challenges due to the limitations of the current data transfer solutions, especially in terms of completeness of the data." The tool, built around Apple's AppMigrationKit, will support contacts, calendar events, messages, photos, documents, Wi-Fi networks, passwords, and third-party app data — a tacit admission that existing tools are incomplete.

The EU's Digital Markets Act requires interoperability under Article 6(7) and data portability under Article 6(9). By June 1, 2026, Apple was due to roll out new interoperability solutions for notifications, proximity pairing, and audio switching. The UK's CMA has designated both Apple and Google as having "strategic market status" in mobile platforms, securing commitments on app review fairness and developer access to iOS functionality effective April 1, 2026. None of these regulatory regimes accept Apple's premise that switching is already easy.

Apple's market-share defense is a global argument with a local problem

Apple's motion to dismiss, denied June 30, 2025, argued that the DOJ's US-only market definition "masks the worldwide primacy of Android smartphones" (Apple's Motion to Dismiss, Dkt. 86-1). The court rejected that argument. Judge Julien X. Neals found that the DOJ adequately pleaded Apple holds over 65 percent of the US smartphone market and over 70 percent of the performance smartphone market, with significant entry barriers and anticompetitive conduct across multiple product categories.

The DOJ's discovery requests directly target this claim. According to the Joint Letter on Data Discovery, Dkt. 353, the government seeks "user data" including "switching data" — information on how many iPhone users actually leave, and why. Apple has produced ten data samples totaling "more than 24 million data points across more than 900,000 rows," according to Dkt. 387, but has resisted providing a Rule 30(b)(6) witness to explain the databases until April 30, 2026 for financial data and May 29, 2026 for other data. The DOJ called Apple's refusal to designate a witness "literally inexcusable."

The academic literature suggests why this data matters. A 2023 paper in the European Competition Journal by Manuel Wörsdörfer argues that Apple's "closed ecosystem combined with its role as an internet gatekeeper" creates lock-in effects that "a walled product garden" perpetuates, and that data portability and interoperability requirements — while necessary — are "insufficient to prevent" them without addressing Apple's dual role as platform operator and service provider. Research from CEPR by Fiona Scott Morton and colleagues found that Apple's DMA compliance pricing "will block entry and innovation in app stores rather than increasing contestability as the law requires."

Samsung's awkward position

Samsung is not a party to the case, but it is uniquely exposed. In a September 2024 protective-order filing, Dkt. 117, Samsung Electronics America told the court that "the parties will seek competitively sensitive documents and testimony from Samsung" and demanded a two-tier confidentiality structure limiting Apple's in-house counsel access. Samsung's Galaxy Store, its Smart Switch transfer tool, and its smartwatch and digital-wallet strategies are all subjects of Apple's subpoena — data that would reveal Samsung's competitive positioning against Apple in exactly the markets the DOJ says Apple monopolizes.

Apple's filing notes that Samsung "expressly markets a 'Smart Switch' product that allows users to 'seamlessly transfer all content' from an Apple iPhone to a new Samsung smartphone" — evidence Apple wants to use to show switching is feasible. But the existence of a marketing claim and the reality of friction are different things. The CMA found that Samsung's Smart Switch, like Apple's Move to iOS, leaves gaps: subscriptions don't transfer, app-install data is incomplete on iOS, and messaging histories don't fully migrate.

The trial timeline

The parties are now fighting over whether fact discovery closes September 9, 2026 (DOJ's proposal) or January 29, 2027 (Apple's proposal, already granted in the amended order). The DOJ warned in its joint scheduling letter, Dkt. 384 that Apple's proposed timeline "would set this case on a path to the longest time to trial of any antitrust enforcement action in recent years" — 34.3 months from filing to fact-discovery close, compared to under three years for comparable cases. The DOJ proposed a trial date of September 8, 2027. Apple declined to set a trial date, asking the court to revisit it later.

Expert reports are due November 17, 2026, under the agreed schedule, with expert discovery closing January 8, 2027. The court has not yet set summary judgment or trial dates.

Diplomat View

Apple's Samsung subpoena is a high-risk move that reveals the contradiction at the heart of its defense: if switching were genuinely easy, Apple would not need a rival's proprietary data to prove it — its own internal switching metrics would suffice. The fact that Apple is pursuing Samsung's data through international legal channels, nine months into discovery, suggests Apple's own numbers may not tell the story it needs. The EU and UK have already concluded switching is hard enough to require regulatory intervention; the DOJ's case is built on the same premise. The forecast hinges on three variables: whether the Hague process returns Samsung's data before January 29, 2027; what Apple's own switching databases actually show when the DOJ's experts analyze the 24 million data points already produced; and whether Judge Neals accepts a US-market definition that Apple's global-market argument has already failed to dislodge at the motion-to-dismiss stage. If Samsung's data shows meaningful net outflow from iPhone to Android, Apple's defense strengthens. If it shows the opposite — or if the data never arrives — the lock-in narrative goes effectively unrebutted at trial.

• Hague Convention ruling: Magistrate Judge Leda Dunn Wettre has not yet ruled on Apple's motion; any delay beyond mid-2026 likely means Samsung's data arrives too late for expert analysis.
• Expert reports due November 17, 2026: Both sides' switching analyses must be complete by this date, making the next four months decisive for evidence.
• Fact discovery close January 29, 2027: The DOJ has signaled it will oppose any further extension; the Hague process is the primary risk to this deadline.
