How-To Guides from Gadget Hacks

A newer iPhone can text emergency services from a trailhead with zero bars, but that capability isn't something you switch on in advance. It becomes available when you're off-grid and a normal call or text to emergency services can't connect, as long as you're outdoors with a clear view of the sky and using an iPhone 14 or later.

Ask three different people what "Microsoft Copilot" does and there's a good chance you'll get three different answers, and all of them will be partially right. That's the problem. Microsoft Copilot isn't one product, it's a family of surfaces, and each one sees a different slice of your data. Mixing up Copilot Chat with Microsoft 365 Copilot, or a Teams meeting assistant with the standalone Researcher agent, is a common reason people asking how to use Microsoft Copilot for research end up with...

When Spotify shut off the servers behind its Car Thing accessory, the company's advice to owners was blunt: factory-reset the device and dispose of it as e-waste (The Verge, ~20 months ago). Community projects emerged to repurpose the hardware instead (Android Authority, today). Figuring out how to revive a Spotify Car Thing now depends entirely on which software gets installed, since "revived" means at least three different things depending on the project.

Android phones carry a set of safety tools built for exactly this moment, but learning how to use Android Emergency SOS after a car accident really starts with setting it up long before any crash happens. The system can call for help and share a live location without anyone unlocking the phone or dialing a number, triggered by pressing the power button five or more times (Android, earlier this year). As Android Police put it last year, "these tools help only if you set them up beforehand." Even...

TechCrunch's hands-on verdict on the rebuilt Siri AI is blunt: the assistant finally works the way Apple promised, though the review reads more like relief than excitement, closer to a bug fix than a breakthrough (TechCrunch's hands-on review). Scientific American frames the wait differently, noting that Apple has promised, and repeatedly delayed, this more proactive Siri for two years (Scientific American). Whichever framing feels right comes down to something more basic than opinion: can you...

One Windows 11 user says the "Turn on virus protection" notification arrives with strange precision: 4 minutes and 13 seconds after every sign-in, never once after waking the PC from sleep, even though, in the poster's own words, Defender "keeps working all the time and never turns off" (Microsoft Community Hub, last week). That kind of specificity is exactly what makes the alert hard to dismiss and hard to trust. Anyone seeing the Windows 11 "Turn on virus protection" notification pop up after...

Tucked inside CarPlay's Accessibility menu are three tools: Voice Control, Sound Recognition, and a set of display adjustments covering text size, boldness, and color. These count among the hidden Apple CarPlay features that go unused simply because accessibility submenus rarely get opened without a specific reason to check them. None of them is a universal upgrade. Each solves a specific kind of friction for a specific kind of driver, and figuring out which one applies to you is the actual...

Search for how to install macOS on an iPad, and Sidecar dominates the results, Apple's feature for mirroring an actual Mac's screen onto the tablet. A project called Virtual Mac on iPad claims something different: it boots real macOS, the actual kernel and userspace, directly on the iPad's own silicon. The project's repository puts its ambition plainly. People have wanted to run macOS on an iPad for more than a decade, the maintainers write, and "today, that dream comes true."

This guide covers how to disable AI Mode in Chrome on desktop: the shortcuts that show up in the address bar, the New Tab Page search box, and the right-click context menu on Windows, Mac, and Linux. It doesn't touch Google Search's own AI Mode tab, which lives outside the browser entirely and gets a short, separate note near the end.

As of this week, a Samsung Messages alternative app called Messages by OzarksMade is undergoing closed testing through Google Play, with a public launch set for 14 days after its testing Google Group hits 12 members and a post-launch price of $0.99. Treat that as a snapshot, not a finished product. Betas shift, thresholds get hit or missed, and pricing plans change before launch.

Snap two windows side by side in Windows 11, drag the shared border to resize one, and in many cases the other window resizes too, whether you wanted it to or not. Microsoft currently documents a checkbox for controlling that behavior under Settings > System > Multitasking > Snap windows. Some users nevertheless report that the checkbox is missing on their installations, so this guide covers both the documented setting and the available workarounds.

Bluetooth speaker problems rarely have one cause. Microsoft's own support documentation splits them into distinct categories: pairing failures, connection failures, and audio-output failures, each requiring a different fix (Microsoft Support, 3 months ago; Microsoft Support, 3 months ago). Treat all three as the same problem and you'll end up applying the wrong fix for hours.

Turning off Roku's automatic content recognition system took investigators at The Markup 11 to 24 clicks. That click count applies specifically to Roku's ACR setting on Roku TVs, the feature built into Roku's television hardware rather than its streaming sticks (The Markup, 2023). Even after finding it, disabling ACR doesn't answer the bigger question most people actually have: how to stop Roku from tracking what you watch across every app you open. This guide walks through the Roku privacy...

Leave a phone on the dashboard of a parked car on an 80°F day, and the cabin around it will hit 114°F within 30 minutes. Give it an hour, and that number climbs past 130°F, according to Meqtor. Most phones are rated to operate only up to 95°F (Meqtor). Past that point, a phone isn't just uncomfortable, it's running well outside the range it was built for.

On one Android phone, apps, texts, call history, and settings combined added up to less than 132MB, while photos and videos on the same device totaled 76GB (Android Police, 15 months ago). That's a striking example, not a universal rule, but it points toward the real question behind how to reduce Android backup storage in Google Drive: check what's actually filling the account before touching a single setting.

Samsung says the Galaxy Z Fold 8 and Z Fold 8 Ultra can charge from empty to 65% in 30 minutes. In preliminary testing, the Fold 8 Ultra actually beat that mark, reaching 67% in the same window, according to Android Authority testing three weeks ago. That's a real jump from what the Fold line could do a year ago, and it raises the obvious question for anyone hunting for the best charger for Galaxy Z Fold 8 devices: which one actually gets you there?

For years, Apple Notes was a one-way street. Text went in and mostly stayed there, with no built-in way to hand a note back out in a format other writing tools could actually read. iOS 26 changes that by building native, two-way Markdown support into Notes, and this guide walks through how to import and export Markdown in Apple Notes on iPhone, iPad, and Mac.

Google says its notification-abuse defenses cut Android notification volume by more than 7 billion messages a day in 2026, according to Google's security team. That number reframes what looks like a minor annoyance, a browser popup asking permission to send updates, into a large-scale security fight Chrome has been waging for years without much fanfare.

Continuity isn't one setting tucked into a menu. iOS, iPadOS, and macOS bundle nearly a dozen distinct tools under that name, everything from AirDrop and Handoff to lesser-known features like Continuity Sketch and Instant Hotspot (Apple Support, earlier this year). Knowing how to use Apple Continuity well means matching the right feature to the right task, not switching everything on and hoping it sorts itself out.

Google's new Search profile looks like the kind of feature every creator should rush to claim: a dedicated, shareable page that puts your work front and center inside Google Search itself. Before spending time hunting for one, it helps to understand Google Search profile eligibility rules, since they set a high follower bar and apply only in the United States for now. This guide walks through who qualifies, how to run a Google Search profile eligibility check on your own name, and what claiming...

T-Mobile and Verizon opened preorders for the Pixel 11 lineup on the same day, and both are advertising offers that sound like a free phone. Not all of them actually are. T-Mobile's top Google Pixel 11 carrier deals are device discounts tied to which plan a customer is on and whether they trade in a phone. Verizon's flagship switcher offer bundles a device credit into a specific 48-month plan structure. Read the fine print carelessly and the two "free phone" headlines start to look...

Most people assume a TV without Bluetooth means a trip to the electronics store. It doesn't. Bluetooth has become mainstream in most televisions now, but that's only half the picture: plenty of older or specialty sets, like a favorite pair of wired headphones or a plasma TV still hanging on in the den, never got the feature and won't get it through a software update either, according to Wirecutter/NYT reporting from last month. Figuring out how to add Bluetooth to a TV without Bluetooth usually...

If you own an older Pixel, you may have noticed something Pixel owners have not generally expected to see: a promotional notification sitting in the shade next to your texts and calendar reminders. After the Pixel 11 launch, Android Authority reported this week that many users, including one of its own writers, started receiving ads for the new phone on their older Pixel devices.

Apple calls Finder the home base of the Mac: the tool for organizing and reaching almost everything on the system, from documents to a connected iPhone. Most people use about a tenth of it. This collection of Finder tips and tricks for Mac users covers the rest: the browsing, previewing, editing, and search tools sitting in the same window you already open dozens of times a day.

There's no single subscription that gets you every NFL game in 2026. Before picking a setup, answer three questions: do you need your local team's games, an out-of-market team, or the national exclusives that land on Thursdays, holidays, and international windows? The answer decides whether this season costs $55 or several hundred dollars (Marketplace, about a month ago).

Search for the best $100 smartphone in 2026 and the results won't cooperate: every phone reviewers have actually tested this year costs more than that. Samsung's Galaxy A17 5G lists at $174.99, and Motorola's cheapest 2026 model, the Moto G Play, runs $169, with the standard Moto G at $199 (Android Authority, 3 months ago). Even PCMag's "cheap phone" roundup skips $100 entirely; its budget category starts under $300 (PCMag, seven weeks ago).

A microphone icon just showed up next to the system tray, and nothing obviously running should need one. This guide walks through how to see which apps are using your microphone in Windows 11 right now, which ones used it over the past week, and how to shut off access once something looks off.

TSA counted 15 states with a mobile driver's license that worked at its airport checkpoints as of February 2025, a list that ran from California and Puerto Rico all the way to Louisiana and New York (TSA). More states have added the option since then, and checking TSA's Digital ID page is the only reliable way to know if yours is one of them today. This guide walks through how to add your driver's license to your phone: confirming your state and device qualify, completing enrollment, and...

Not every Galaxy Watch 9 health feature behaves the same way out of the box, which is exactly why deciding which Galaxy Watch 9 settings to enable on day one matters. Hard fall detection is a genuine toggle, and it ships off by default, doing nothing until someone switches it on (Samsung Support). Vitals and Sleep Coach aren't toggles in that sense. Vitals needs seven nights of overnight wear to build a baseline before it can flag anything unusual, and Sleep Coach needs at least seven days of...

A guide posted on XDA Forums last year describes a way to run Samsung DeX on a Galaxy Z Fold's internal screen, with no monitor, dock, or book cover attached.

Apple took away the iPad's old job. It can no longer act as a Home hub; that role now sits strictly with HomePod and Apple TV. A small independent app called HomeDeck bets there's still a use for a spare iPad in a smart home: not as the brain, but as a HomeKit dashboard for iPad that displays an Apple Home someone has already built out. HomeDeck's own pitch is a dedicated screen, not a replacement for the hub sitting underneath it.

10 Gboard Features That Make Android Typing Faster — and 5 Settings That Make It Less Nosy

Screen mirroring an Android phone to a Roku takes only a few taps, but only if both devices support Miracast, the wireless display protocol Roku relies on. Pixel owners should skip mirroring altogether and lean on in-app casting instead, since Google built its phones around Google Cast and DIAL rather than Miracast. That one branching decision, Miracast or not, determines almost everything else in this guide.

In June, Chris Graue made headlines for photographing Jupiter with a Game Boy Camera, a 1998 accessory whose sensor captures 128×128 pixels in four shades of gray. The image showed cloud bands and a clear planetary limb. The catch: Graue shot through the Hooker Telescope at Mount Wilson Observatory, one of the most historically significant instruments in American astronomy. The camera was the hook. The adapter and the 100-inch mirror behind it were the story.

Every Mac includes Preview, Apple's app for opening PDFs and images. Double-click a supported file, and it will usually open without another download, subscription, or setup process.

How Windows 11 Wi-Fi problems are easier to fix when you start with the symptom. A missing Wi-Fi toggle, a "No Internet, Secured" warning, random drops, and post-update connection failures all point to different causes. Use the section that matches what you see, then try the targeted fix.

Google has been replacing Google Assistant with Gemini in Android Auto, with the rollout expanding to 45 languages globally, per Google's announcement. If your phone already runs the Gemini app, you likely have access or will soon. The change matters more than a typical assistant update: Assistant frequently failed to register voice input at all, something a Tom's Guide tester called a near-daily occurrence. Gemini also removes the rigid syntax problem, so you can speak naturally and hold a...

Run powercfg /hibernate on in an elevated terminal, then go to Control Panel and check the Hibernate box under power button settings. That's it. Many guides stop after the command or the Control Panel step this one covers both, in order, with the gotchas called out where they matter.

This guide covers whether turning off Google Play Protect is the right call for your situation, how to do it if it is, and the specific steps to take immediately after. Skipping that last part is where most people get into trouble.

Apple Car Key stores a credential in your Wallet app and uses it to lock, unlock, and start a compatible vehicle no separate app, no cellular connection required. Setting up a car key on iPhone takes about five minutes once you know you're eligible. The part that trips people up is figuring out whether they actually are.
