iOS 27.3 Beta adds Vietnamese to Siri AI alongside Apple's hardware and memory challenges

On November 3, 2026 US time (early morning November 4 Vietnam time), Apple released iOS 27.3 Developer Beta 1 for developers and beta testers¹,³. This update marks a major milestone as the artificial intelligence-integrated virtual assistant Siri AI officially supports Vietnamese¹,³, fulfilling the company's prior commitment¹.

Siri AI officially supports Vietnamese on iOS 27.3 Beta

The iOS 27.3 Beta update brings the ability to interact with Siri AI in Vietnamese¹,³. Reports indicate that Vietnamese, along with Traditional Chinese, Turkish, and Norwegian, brings the total number of languages supported by Siri AI to approximately 10¹.

To use Siri AI in Vietnamese, users must own devices that support Apple Intelligence such as the iPhone 15 Pro, 15 Pro Max, iPhone 16 series and later, iPhone Air, iPhone Duo (and corresponding iPad/Mac/Watch/Vision Pro models)¹. Apple requires both the system display language and the Siri language to be uniformly set to Vietnamese¹. This feature does not currently support users under 13 years of age and is not available in the European Union (EU)¹.

Alongside Siri AI, this beta version also redesigns the Health app to support new languages including Vietnamese for Insights and Health Age features¹. Safari gains vertical tabs along with Adaptive Dark Mode, while the Fitness+ app adds a Gym Strength mode¹. Users can update via the developer beta settings, though sources recommend backing up data prior to installation as experimental versions may experience battery drain issues¹,³.

CEO John Ternus addresses iPhone Duo screen issues and supply chain

Also in early November 2026, Apple CEO John Ternus shared public remarks with Reuters regarding issues surrounding the iPhone Duo foldable phone lineup². According to Ternus, only a very small percentage of iPhone Duo devices have been returned by customers due to screen issues involving cracks or lines near the folding area, and Apple is implementing a device replacement policy for these cases².

Despite recording some hardware defects, demand for the first foldable iPhone model—starting at $1,999—continues to exceed the company's supply capacity². According to data from Bank of America and IDC, buyers may face long wait times to receive their units due to constrained supply, and Apple cannot yet accurately predict when supply and demand will balance².

Financial pressure from the global memory chip crisis

Apple's fourth-quarter financial report showed global revenue reaching $114.48 billion, exceeding analysts' forecasts, with iPhone revenue alone hitting $57.58 billion²,⁴. However, in the earnings report released by CEO John Ternus and Chief Financial Officer Kevan Parekh, Apple projected that its gross profit margin for the final quarter of the year would decline to between 45% and 46%²,⁴.

The primary reason cited by Apple is the impact of record-high memory chip costs in the global market alongside the expenses of deploying Siri AI²,⁴. CFO Kevan Parekh stated that the company is under pressure from RAM shortages as major AI data centers aggressively buy up components⁴. To secure supply, Apple increased its component purchase commitments by approximately $33 billion during the quarter²,⁴.

Vizy's take

According to Vizy, Apple's acceleration of the rollout roadmap bringing Vietnamese to Siri AI just two months after the new iPhone lineup launch demonstrates that the Vietnamese market is receiving genuine attention in the company's localization strategy. Nevertheless, integrating next-generation artificial intelligence features into the ecosystem concurrently with the global memory chip crisis poses a significant cost puzzle for the new leadership under CEO John Ternus. Vizy believes these margin fluctuations clearly reflect the hardware supply chain pressures that even a massive technology conglomerate can hardly stay immune to in the short term.
