Some folks find that the iPhone’s noise-cancellation feature causes a weird, uncomfortable sensation. It’s a product of the way the technology works, as Apple Discussion member KiltedTim says, linking to HowStuffWorks:
“In order to cancel out background noise, the sound is not “eliminated” from the audio stream you’re hearing. It is countered by a second audio stream that basically eliminates your ability to hear it.
Since the sound and the “counter sound” are still hitting your eardrum, this can result in an odd sensation. Your ear is processing the sound, but your brain isn’t registering it. Since the inner ear controls balance, this will produce a dizzying effect in some people.”
If this is bothering you, here’s how to turn off the noise-cancellation feature, which Apple added to iOS 7. (Originally exclusive to the iPhone 5s, noise cancellation is now available to older devices in iOS 7.1.)
We’ve all had to do it: make those conference calls to services that require you to enter in a code, or a room number, or what have you.
If you call these numbers frequently and want to save a little time, you can enter in the extensions and codes into your Contacts app, but you’ll want to code in the bit of wait you’ll need for the conference call system to recognize it.
It’s easy to do, and you can do this right on your iPhone.
We’ve been using the Do Not Disturb function on our iPhones since iOS 6, really, as the feature really helps us have some down time. You can schedule or enable the feature for easy access, keeping those pesky calls, messages, and notifications off your iPhone screen when you just don’t have the brain space to deal.
But what about those calls and messages you really do need to get? What do you do there? Luckily, there are a couple of options to let certain calls come through.
Sure, a simple passcode with four numbers will keep most casual folks out of your iPhone, but if you want it to be really secure, you should think about using an alphanumeric password, like you would on a website or your Mac.
The idea here is simple, the more characters you have (and the less obvious your password is), the better your security. Balancing a large enough number of characters with ease of recall can still be tricky, but I’d bet you’ve got it fairly worked out on the websites you visit — why not use that same acumen on your iOS devices?
Here’s how to turn off the simple passcode in iOS, and set up a more secure one.
Sure, it’s nice to know you have a bunch of unread email messages. And it’s understandable that iOS apps notify you about every little activity. But after a while, all the little numbers in the red circles on my iPhone’s home screen start to feel like a chore.
I hate having to open up apps just to clear out the taunting little numbers. I could ignore them, but they’re designed to bother me (or, more politely, to get my attention). I mean, I have healthy emotional boundaries, but this is getting ridiculous.
I personally can’t stand audiobooks except under one specific condition. I like them when I drive long distances. There’s something about listening to a book being read to me that puts me to sleep if I’m anywhere else, but for some reason, I’m able to listen in the car.
Now, I purchase a lot of iBooks, but not many audiobooks. One reason is that they’re more expensive, but I mainly avoid them for the reasons above. However, when I next take a cross-country trip in a car, I’m going to use this tip to turn the written iBooks into ones I can listen to off of my iPhone or iPad.
Sure, you can ask Siri to call one of your contacts; it’s one of the ways I make calls handsfree in the car. Simply say, “Call Kim” (or the name of the contact you’d like to call–you may not know Kim), and Siri will place a voice call to that Contact.
Did you know, however, that Siri can handle even more complexity? Yes, yes it can.
