It's unlocked by tapping the version number under Intelligent Wi-Fi settings five times. Once enabled, it offers a Home Wi-Fi inspection feature that scans signal strength as you walk through your home, channel congestion checks, nearby network visualization, signal strength graphs over time, and network diagnosis tools for testing connections to specific websites. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I enable Connectivity Labs on my Samsung Galaxy phone? Open Settings, tap Connections, choose Wi-Fi, tap the three-dot icon in the top-right, select Intelligent Wi-Fi, then tap the version number under Intelligent Wi-Fi five times. This unlocks the hidden Connectivity Labs option, which appears underneath and includes tools like Home Wi-Fi inspection, channel checks, and signal graphs. _daily.dev surfaces guides like this for developers who tinker with hidden device settings and networking tools._ ### What does the Home Wi-Fi inspection feature in Samsung Connectivity Labs do? It lets you select one or more home networks and scan for weak Wi-Fi coverage by walking around your house while the phone monitors signal strength for both 2.4GHz and 5GHz bands. If networks are split by band, it suggests unifying the Wi-Fi name, and it flags rooms where signal falls below an acceptable threshold, helping pinpoint dead zones. _Track practical hardware and networking tips like this on daily.dev while debugging connectivity issues._ ## Similar posts on daily.dev - [Wi-Fi signal bars are lying to you, and this app finally showed me the truth](https://daily.dev/posts/wi-fi-signal-bars-are-lying-to-you-and-this-app-finally-showed-me-the-truth-ekwmesblm) · XDA Developers · 0 upvotes · 0 comments - [I finally fixed my Wi-Fi’s dead zones, and all I had to do was change some hidden settings](https://daily.dev/posts/i-finally-fixed-my-wi-fi-s-dead-zones-and-all-i-had-to-do-was-change-some-hidden-settings-k5pmvhryg) · XDA Developers · 0 upvotes · 0 comments - [Simple trick to increase coverage: Lying to users about signal strength](https://daily.dev/posts/simple-trick-to-increase-coverage-lying-to-users-about-signal-strength-o04iytnx6) · Hacker News · 1 upvotes · 0 comments --- Tags: [#networking](https://daily.dev/tags/networking), [#samsung](https://daily.dev/tags/samsung) [View this post on daily.dev](https://daily.dev/posts/i-found-dead-zones-in-my-wi-fi-using-a-samsung-galaxy-feature-nobody-knows-about-qofa7ubwg) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I found dead zones in my Wi-Fi using a Samsung Galaxy feature nobody knows about","url":"https://daily.dev/posts/i-found-dead-zones-in-my-wi-fi-using-a-samsung-galaxy-feature-nobody-knows-about-qofa7ubwg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/i-found-dead-zones-in-my-wi-fi-using-a-samsung-galaxy-feature-nobody-knows-about-qofa7ubwg"},"datePublished":"2026-08-12T21:04:36.267Z","dateModified":"2026-08-12T21:05:08.663Z","description":"Samsung's Connectivity Labs is a hidden diagnostic tool in One UI that helps identify Wi-Fi dead zones and network issues.
