Ktorý z týchto reportov by ste mali vygenerovať, ak chcete zistiť, či sa správanie používateľov na stránkach s podrobnosťami o výrobkoch mení v závislosti od zariadenia, ktoré používajú?

The "Pages and screens" report is correct because it allows you to analyze user engagement with specific pages, such as product detail pages. By applying a secondary dimension for "Device category," you can directly compare user behavior (like views, average engagement time, and conversions) on those pages across different device types (desktop, mobile, tablet). This directly addresses the question of whether behavior changes based on the device used. "Tech details" focuses on browser, operating system, and screen resolution, not directly on page-level behavior by device category. "User acquisition" shows how users arrived at your site, not their behavior on specific pages. "Events" tracks specific interactions, but doesn't inherently group page behavior by device without significant custom setup.
