Roku OS 15 Rollout Adds Features, Sparks Complaints
Roku has begun a phased rollout of its free OS 15 software update to millions of devices, bringing features such as an expanded Sports Experience hub with live scores and game reminders and improved HDR10+ and Dolby Vision support. The update is reaching much of Roku's TV lineup, including models from TCL and Hisense. The rollout has generated user reports of serious technical issues — including severe lag, pixelation, and unexpected factory resets — posted on Roku community forums. Roku is also managing other platform software issues, such as audio dropouts on the Fandango at Home app and persistent complaints about third‑party app performance (for example, Apple TV).
Roku is a major CTV platform; an OS release that adds features (sports hub, HDR/Dolby support) but produces widespread user‑reported glitches can affect viewer experience, third‑party app performance, and CTV ad inventory reliability across millions of devices.

Roku Rolls Out Roku OS 15.2 Update
Roku has begun a phased rollout of its Spring software update, Roku OS 15.2, to compatible Roku TVs and standalone players. The staged deployment may take several weeks to over a month as Roku monitors stability and performance. The release emphasizes developer-focused improvements — including a Perfetto-based app tracing tool with BrightScript heap graph visualization, a new chanperf command via the External Control Protocol to surface raw Linux CPU/process stats, expanded BrightScript APIs (low-memory notifications, remote-control repeat delay/rate queries), and AES-GCM cipher support. Roku says the under-the-hood changes aim to improve navigation, app launch speed, playback reliability and multitasking for end users. Device compatibility varies by model and some legacy hardware may receive limited features or delayed updates.
Roku OS 15.3 Rolls Out to Select Devices
Roku has begun a limited rollout of Roku OS 15.3 to select Roku TV devices and streaming players, though the company has not issued a public consumer announcement and lists the build as available through its developer beta program under NDAs. The update is primarily developer-focused, adding a captionRenderArea field to SceneGraph for advanced caption placement in non-fullscreen video, support for Double value types in SceneGraph, new BrightScript functions (including roUtils predicates), ordered-value retrieval for roAssociativeArray, higher-precision timing in roTimeSpan, and pretranslation offsets for roAnimatedImage. The distribution follows Roku’s typical staged rollout pattern; devices generally update automatically when connected to the internet.
Roku Begins Testing OS 16 with Developer Features
Roku has started rolling out Roku OS 16.0 to selected developers for private testing. The update introduces a built-in effects layer for channel developers to create rounded corners, borders, and color fades without extra artwork, plus support for live event streams and WebSockets for real-time updates. It also adds a customer identifier feature for stores, improved drawing command feedback for direct-draw apps, and several housekeeping changes. The update is expected to fully roll out to consumers in the coming months, with more features to be announced. Most channels will require no changes, but developers using the older direct-draw path should review their code.
