12 Secret iPhone Hacks (that even Experts don't know about)

Think you know the full power of your iPhone?

Think again.

Most people don't realize how crazy powerful their iPhones are.

And many never bother with the handy (and secret) hacks that make the iPhone even cooler!

I'm not talking about popular stuff -- like customizing backgrounds or playing video games from the '90s.

Nah, the secret iPhone hacks I'm talking about (and the ones I list below) are actually useful.

And they'll make your iPhone experience better than you ever dreamed.

12 Secret iPhone Hacks (that even Experts don't know about)

1. Use your iPhone like an Etch-a-Sketch

Fat-fingered peeps will love this!

Your iPhone can work like an Etch A Sketch.

Don't believe me?

Try shaking your phone next time you type a mistake. The shaking should clear the screen and let you start again.

It doesn't matter if you're writing a text message or editing a pic -- just give your phone a shake next time you make a mistake.

2. Invert Display Colors to Browse at Night

Want to browse at night without disturbing everyone in the room?

Apple's got you covered!

Just invert the iPhone display colors -- it's easier on the eyes and you can surf the web and email without waking your spouse and kid.

3. Turn Off Autofocus in a Tap

Autofocus got you down?

Are you the kind of photographer who likes to do it yourself?

You can turn off your iPhone's autofocus when the nagging little feature gets in the way.

In camera mode, hold the screen until you see "AE/AF Lock."

4. Swipe Left to See Text Timestamps

Need to see what time that text message was sent?

On an iPhone, it's a cinch!

Just swipe left on the text screen.

5. Tell Siri Your Relationships

Have you ever told Siri to simply call your "husband"?

How about your "mom" or "son"?

Siri can do it with one easy hack.

Ask Siri to call your "dad" and your phone should respond by asking who your father is. Next time Siri will reach your dad straightaway.

Match the right contact and it'll only take a "Call dad" to get your pops on the horn.

6. Charge Battery Faster in Airplane Mode

Your battery will charge in a hurry if you switch your iPhone to airplane mode.

7. Access Numbers Super Quickly

Tired of using the numerical keypad to type numbers in an email or text?

There's a hack for that!

Just hold the "123" button and slide to the numbers you need. Your iPhone should then revert to the original keypad.

8. Use Siri to Check Twitter

You don't have to open Twitter to see who's saying what online.

Ask Siri "what Userx is saying" and you'll see a list of our recent tweets.

9. Finish URLs in a Snap

Use the "." key next time you search for a URL on your iPhone.

Holding down the "." key will reveal suffixes like ".com" as you type a website URL.

10. Shoot Series of Photos All at Once

If you hold down the Capture button when using your iPhone camera, your phone will automatically take a series of photos so you can pick the best one.

11. Know What Your iPhone Knows About You

Have you ever checked out the "Frequent Locations" on your iPhone?

It's amazing (and kind of scary)!

Your iPhone knows where you hang out the most and is prepared to reveal these locations any time.

Be careful out there. ;)

12. Never Use Passcode "1234" Again!

Even amateur hackers make cracking a 4-digit password look like child's play.

That's why Apple makes it easy to create a password that's more complex.

Click Settings > General > Passcode Lock to turn off the simple passcode -- then enter something that's harder to figure out.

BONUS Hack...

This could be the most useful iPhone hack on the list!

Have you heard of IF by IFTTT? It's the iOS app that lets you create IFTTT recipes to connect your favorite apps so they work harder for you.

Did you know you can hack your social media accounts with this nifty trick?

Best part? You can do it all from your iPhone.

Or have it automatically pin that post to a specific board on Pinterest.

Or have it automatically send that post to your Gmail to remind you to put the pic on Instagram later.

The options for how you can link your social networks are endless!! (and free)

Time to Hack!

Awesome, right!

Now it's your turn. Have you ever used your iPhone as an Etch A Sketch? Have you hacked your social media accounts with your iPhone?
