How-To Guides from Gadget Hacks: Page 2

Open the Health app on your iPhone and there's a feature tucked inside that can hand a paramedic someone's blood type, list their allergies, and name who to call when they can't answer for themselves. It only works, though, if someone filled it in before the emergency happened. This guide walks through how to set up Medical ID and emergency contacts on iPhone: building the medical profile, adding contacts, deciding what to expose on the Lock Screen, configuring Emergency SOS without triggering...

Some PCs upgrading from Windows 11 23H2 or 24H2 to 25H2 have run into a confusing failure: "We couldn't update the system reserved partition," sometimes accompanied by error code 0x800F0922 or 0xC1900104.

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.

This guide walks through how to use Visual Intelligence on macOS Golden Gate: what your Mac needs before turning it on, the keyboard shortcuts that trigger it, the in-app option built into Siri's systemwide context menus, and which questions are actually worth asking it.

Apple began offering new and qualifying returning subscribers three free months of Apple One with the purchase of an eligible device on September 17, 2026. If you're trying to figure out how to get the Apple One 3-month free trial after buying a new device, the first question isn't which iPhone you bought. It's whether your Apple Account qualifies at all.

Windows 11 offers several built-in ways to capture a screen, and each one saves the result somewhere different. Pick the wrong shortcut, and you can end up with an image stuck on the clipboard with no file to show for it, or a PNG saved somewhere you weren't expecting.

An old Mac mini doesn't have to end up in a drawer once a newer model takes over your desk. Turning an old Mac mini into a home server is one of the more practical uses for hardware that's small, quiet, and easy to tuck away where noise and space matter.

By the end of this guide, the regular Gmail Inbox does the sorting itself. Priority senders stay visible, receipts and newsletters get labeled and archived automatically, and subscriptions that just add clutter get canceled at the source. None of it runs through Gemini, Smart Reply, or Gmail's own tab classification, since this is a guide to Gmail inbox automation built entirely from rules typed in by hand.

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?

The 78th Emmy Awards aired live on September 14, 2026, but anyone who missed the ceremony can still watch the 2026 Emmy Awards without cable.

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.

A phone that works fine at home can go dark within minutes of touching down in China. Not because one app breaks, but because three separate systems, internet access, navigation, and mobile payment, all require setup steps that are much easier to handle before you've already landed. Figuring out the best apps for traveling to China matters less than getting that setup order right before you leave.

Audible buries a handful of useful features behind menu labels that don't always explain themselves clearly.

CarPlay automatically adds every compatible app on the iPhone to the display, with no ranking of what actually matters while driving (Pocket-lint, two months ago). That means the default layout may not reflect what's useful behind the wheel. Apple built CarPlay to put iPhone tasks, navigation, calls, messages, onto the car's built-in display rather than the phone screen (Apple Support, last year). Connecting the phone gets those tasks on screen, but the deeper controls, app order, notification...

Open System Settings after installing macOS 27, and Apple Intelligence might be claiming far more space than Apple's own numbers suggest it should. That's the pattern surfacing on Mac forums this week: multiple owners running Apple's newest macOS release are seeing Apple Intelligence storage usage on Mac systems run well past what Apple's support documentation lists as the requirement. MacRumors measured 20.67GB on its own M4 Pro Mac mini, already above Apple's published 14GB ceiling for that...

Scroll through a playlist and find half the tracks dimmed and unplayable, and the timing feels random: was it something you did, a subscription hiccup, or the label pulling the song outright? If you're searching for Apple Music songs grayed out how to fix, the troubleshooting path is more structured than the scattered advice online suggests. Apple's own Cloud Status labels, "Waiting," an exclamation mark, or "No Longer Available," point to different likely causes, and only some of them respond...

If the dedicated Copilot key on your laptop keeps opening an AI assistant you never asked for, here's how to remap the Copilot key in Windows 11 so it does something useful instead. Use Windows Settings if you want the key to open Search or a specific app from its built-in list. Use PowerToys Keyboard Manager if you want the key to fire a keyboard shortcut or open whatever's pinned to your taskbar. Turning the key into a standalone Ctrl is also possible through PowerToys, though it behaves...

A Messages background isn't a private wallpaper choice. It's a setting tied to the conversation itself: everyone in the thread sees whatever background gets applied, and anyone in that thread can change it again later (Apple Support). Learning how to change iMessage background on iPhone only takes a few taps, but knowing who else it affects matters more than the taps themselves.

Here's how iPhone Handoff works in iOS 27: supported carriers can put the same phone number on two iPhones, but only one of those phones is ever active at a time. It's not two simultaneously active lines, and treating it that way is the fastest way to misunderstand what you're paying for (MacRumors explains).

An ASUS laptop running slow on Windows 11 rarely comes down to one mystery cause. It's usually a process using too much CPU, memory pressure, low storage space, an older hard drive, heat buildup, or a power setting working against you. Sometimes more than one problem is involved.

Most CarPlay customization doesn't happen on the car's screen. App order and widgets are managed from the paired iPhone, while wallpaper, display appearance, text size and Smart Display Zoom are adjusted through CarPlay itself.

Apple TV boxes don't use automatic content recognition to identify everything playing on a television, and an Apple TV 4K can't inspect video coming through the TV's other inputs. That gives the box a privacy advantage over many smart TVs and streaming platforms, as Ars Technica reported in 2025.

If your Pixel 11 keeps dropping Wi-Fi, shows a 5G icon without usable data, or cuts out over Bluetooth, that doesn't automatically mean the phone is defective.

iOS 27 now lets iPhone owners create their own Apple Wallet passes without a developer account.

Downloading a map to an iPhone before a hike doesn't guarantee it will still work once the signal drops. Gaia GPS's own support documentation warns that its app caches recently viewed tiles, so a trail can look available offline even though it was never actually downloaded. That's a quirk specific to how Gaia checks download status, not proof that offline map apps generally fail (Gaia GPS Help, 5 months ago).

Some Mac owners running macOS 27 have watched Apple Intelligence balloon to 20GB or more in the Storage pane, well beyond what Apple's own documentation says it should need. If you're trying to figure out how to remove Apple Intelligence models on Mac and claw back some of that space, start by separating what's actually been measured from what's circulating on Reddit.

Google Photos still has a setting that restores date headers in the grid. On Android, the redesigned Photos view switched those headers off by default and replaced them with a floating date indicator that appears while scrolling.

Backing out of an app, opening Settings, and scrolling through the full app list just to flip one permission toggle is a small tax most iPhone owners pay eventually. This guide walks through how to add an Open App Settings shortcut to Control Center, a one-step Shortcuts action that, according to reporting, jumps you from whatever app you're using straight to that app's own settings page, skipping the manual hunt through the list (Digital Today reported earlier this year).

Firefox for iOS now has a built-in ad blocker. Mozilla shipped it off by default, though, and you can now enable the feature from the app's main settings or the Site menu on a webpage. If you're trying to figure out how to enable ad blocker in Firefox on iPhone, the process itself is short. What takes longer to explain is what the feature actually filters once it's on, and where it stops.

Searching for how to watch 2026 US Open Round 2 live for free won't turn up a current live option because Round 2 is already over.

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.
