iOS 11

Malevolent hackers can divert your incoming calls and texts to any number they want, and they don't need to be a criminal mastermind to do it. Even friends and family members can reroute your incoming calls and messages so that they know exactly who's trying to reach you, and all it takes is seconds of access to your iPhone or wireless account. These secret codes can help uncover them.

Almost 190 secret characters are hiding behind your iPhone's default keyboard, and I'm not talking about what you see after tapping the "123" or "#+=" keys. These special composite characters can include accents, dots, and other diacritics, and you'll even see some strange typographical characters like the section sign, inverted marks, and per mille symbol. Here's how you find them.

You may know the traditional way to take a screenshot on your iPhone, but it may not be the best action for your needs. There are faster ways to capture an image of your iPhone's screen, methods for capturing overlays and other elements that won't show in regular screenshots, and even options for blocking screenshot thumbnail previews from appearing.

In recent years, Apple has been pushing health and safety as cornerstones of its technology, and iOS 11 is no exception. Apple's latest entry in its mobile operating system brings a new emergency feature called Emergency SOS, which gives you easy access to contact 911 if you press the sleep/wake button five times. It's a useful way to contact emergency services when you might otherwise not be able to.

Apple's Shortcuts app lets you make and use custom icons for any app on your iPhone, but it won't actually replace any icons. If your goal is to change the official icon for the app itself without any redirects, there's a growing list of third-party apps that'll let you do just that.

Ringtones and text tones can be annoying, so my iPhone is almost always set to vibrate on silent mode. Unfortunately, that causes me to miss phone calls and text messages when the device isn't in my hands or pockets. While I hate missing alerts, I'm still reluctant to switch to ring mode — and that's where another iOS and iPadOS feature helps out.

Apple has a secret iMessage effect so hidden that there's only one way to unlock it, and it's not by digging through the Messages app's settings, tools, effects, or interface. However, it's used the same way whether you're messaging from an iPhone, iPad, or Mac, so it's easy to remember once you know.

There's a feature hiding in your iPhone's Mail app you may have missed but should definitely know about. It gives you quick access to something you'd typically have to dig around in folders to find.

When you look at your status bar on your iPhone, you'll almost always see the battery icon, which gives you an estimate of how much battery life you have left before you need to charge the device. What you won't always see is the exact battery percentage, but there are multiple ways to force it out of hiding.

There's a whole world of hidden iPhone features you might be missing out on, but this little-known tool for iOS is something you should definitely enable so that it's ready when you need it.

You can double-tap most maps on your iPhone to zoom in, and tap once with two fingers to zoom out. And I'm sure you're more than familiar with the pinch gesture for zooming. But there's an even better way to zoom in and out on maps, and you can do it with one hand tied behind your back.

A little-known setting on your iPhone gives you the power to change the color of certain contact names and email addresses when drafting an email. Customizing the color works well for visually separating contacts at a glance, and it can even help you from sending an email to the wrong person.

Gmail uses TLS, or Transport Layer Security, by default for all email communications, so all of your emails will use the standard encryption as long as the recipients also support TLS. But there's a way to add even more security to your Gmail emails, and you can use your iPhone's Mail app to do it.

You can set a GIF as the wallpaper for your iPhone's lock screen, but it won't animate like it does when looking at the image in the Photos app. It's an annoying limitation on iOS, but one that's easily bypassed with a tiny bit of work.

Whether you drop your iPhone into a toilet or your dog's water bowl or regularly take it into the shower or pool, water will likely become nestled inside its speaker grilles. Water exposure causes audio playback through the speakers to soften and sound muffled, and getting that water out is no easy task. Luckily, there's an app for that.

You see it in the movies all the time. A character on the phone doesn't like what the other person is saying or telling them to do, or they just don't want to talk to them anymore, so they fake bad reception and cut the call off. In real life, it's pretty easy to tell when someone is doing it, and there are better ways to end a call abruptly so that it looks like you didn't hang up on them.

After just a few hours, your iPhone's app switcher can become cluttered and even chaotic enough that you won't even want to use it. If you like your app switcher clean and tidy, with only your current session's apps accessible, there's a trick to force-quitting all apps simultaneously rather than one by one.

Unless you have unlimited cellular data, you probably connect your iPhone to every Wi-Fi network you come across. It could be a local coffee shop, public library, or just a friend's place. Wherever it is, you'll need to ask for the access point's password if it's a secured network, and that can be a hassle if the place is busy or the owner forgets the credentials. Luckily, Apple has a solution for this problem.

Ah, the dreaded "green bubble" group chat. All it takes is one non-iPhone contact to turn an entire thread from iMessage paradise to SMS slog. Normally, it isn't that bad since the group chat still functions. However, sometimes, you end up getting messages individually instead of in a single group thread. Before you go blaming your Android friends, know that the issue is probably on your end.

Your iPhone keeps track of every single place you go, especially those you frequent most often, and syncs those locations across all your iCloud-connected devices. People who gain access or already have access to your iPhone, iPad, iPod touch, or Mac may be able to view all of these locations to see where you've been and where you might be. If this worries you, there are things you can do.

When you're checking out photos and video on Instagram, its default bright white layout can literally be an eyesore, especially in dimly lit settings where the bleached UI feels blinding. Luckily, there's a really simple way to switch from the normal light mode to a dark mode look in the iPhone and Android app.

You take a photo or video, send it to a friend, and they say, "Hey, I can't open this." More often than not, your friend won't be using an iPhone, iPad, iPod touch, or Mac. Instead, they're likely trying to open the file with a non-Apple device. But this problem can be avoided if you know what setting to change.

Even with the convenience of online storage like iCloud and Google Drive, data management can be a constant struggle on your iPhone. If you continuously find yourself having to delete messages, photos, videos, and other files to make room for other things, know that there's an easy way to free up space without erasing anything important or having to dig through documents and data yourself.

Amber, emergency, and public safety alerts on an iPhone are loud — startle-you-to-death loud even. They can happen at any time, day or night, and sometimes back to back when you're in a big city. Those blaring sirens can wake you from sleep, interrupt an important meeting, or disrupt an entire movie theater mid-movie, but you can turn most of them off if you're tired of hearing them.

If you're on a cellular plan with a low data allotment, being thrifty with your data can help you avoid a higher bill. But even if you have an affordable unlimited plan from wireless carriers such as T-Mobile or Verizon, going over a certain amount of data may throttle your connection, leaving you with slow web speeds. One way to prevent hitting these thresholds is to keep certain apps in check.

Between sending iMessages, jotting down notes, and crafting emails, you do a lot of typing on your iPhone. No doubt, you've been in the middle of an important task when everything comes to a screeching, obtrusive halt, where a rogue "Undo Typing" pop-up forces you to close it before continuing with your typing. Don't put up with the BS anymore — here's how to stop it.

You might be giving out your name to every stranger you see, and you don't even know it. That iPhone of yours has a name — generally a combination of your first name and device model — and it broadcasts it to others via AirDrop, Personal Hotspot, Bluetooth, Wi-Fi, and other connections. Sure, it's useful to keep your device name simple and to the point, but there are upsides to changing it.

Since iOS 6, "Respond with Text" has allowed us to quickly respond to a call we can't (or don't want to) answer. But Apple only gives you three options to choose from, and if you don't have time to type out your own response, those three might not cut it. Luckily, you can customize these three replies to whatever you want.

If you're like me, no matter how hard you try, your iPhone's notifications are a mess. There's just too many of them. That's when it becomes helpful just to get rid of the whole bunch and start fresh. However, deleting alerts one at a time is as tedious as it is unnecessary since you can clear all of your notifications at once.

It's almost impossible to use Apple News at night without having to mess with the white point and zoom filters. That might sound a bit dramatic, but it's really not when you consider that iOS 13 has a perfectly good Dark Mode that should work for News. So why are we stuck reading most news stories in Light Mode? We're not, but you have to put a little work into it going dark in News.

If you have a limited mobile data plan on your iPhone, you know how tricky it can be to stay within your given allotment. Large app installs and updates, 4K resolution videos, and photo backups can waste precious data resources in no time. And apps like Apple News, Facebook, Mail, and Netflix eat data like it's candy. But you can nip the problem in the bud by restricting data hogs from your cellular network.

You're out and about, and nothing on your iPhone will load. A glance at the settings shows a saved Wi-Fi network with full bars that your iPhone had connected to automatically, but you're not getting any internet. If you've experienced this, you're not alone, and there's something you can do about it. You'll even increase privacy and security on your iPhone in the process.

We're beyond the days where iPhones fit perfectly in most hands. The iPhone 11 Pro is still a bit big for many people, and the 11 Pro Max is truly massive. If you're having trouble typing out your thoughts without using two hands, know that there's a quick way to make one-handed typing possible on any iPhone.

Apple introduced third-party keyboards back in iOS 8, and swipe-input options like Gboard, SwiftKey, and Swype made typing on an iPhone one-handed much easier. Even better, apps like Word Flow moved the keyboard to the side of the iPhone, so there was less thumb-stretching. Well, ever since iOS 11, Apple has had its own option for better one-handed typing in the stock keyboard.

The camera on models in the iPhone 11 series includes an ultra-wide lens to take wider images, Night mode for taking better-looking photos in low-light environments, and a 16:9 frame for shooting. With these new features comes a slightly redesigned interface in the Camera app, one that even the second-generation iPhone SE received despite only having one of those three features.

Since its introduction on the iPhone 5S, Touch ID has made unlocking Home button iPhones quick and secure. The second-generation iPhone SE brought back the beloved feature in 2020 but didn't take any steps to improve on the technology. So if you're rocking Touch ID and having trouble getting it to read your fingerprints, there are some things you can do to fix it.
