If you want a more accurate gauge of your signal strength, you can actually change it into numbers. First, dial *3001#12345#* and press Call. Your iPhone will then be set to field test mode. Just press and hold the power button until the slider appears. Then, press and hold the home button until your home screen appears. Notice that the signal bars have now turned into negative numbers? You want to get as close to zero as you can. If your signal strength indicator says it’s above -80, it means you have a strong signal. But if your signal falls below -100, it means you’re in a bad signal spot.
Take Great Photos Faster
Since taking pictures is what we all usually do on our iPhones, it’s imperative to have the iPhone’s camera ready at all times. One of the key features on the iOS 6 is the camera icon on the lock screen. Just press the wake button and you’ll notice that the camera icon is now beside the unlock slider. However, you can’t tap the icon. To launch the camera you have to drag it to the top of your screen. And if you’re using your headphones, you can also take a picture by simply clicking on the volume controls on your headphone cord. This will speed up your photo taking and you’ll avoid blurred pictures because of your shaky hands!
How to Block All Calls and Texts
Sometimes, you just have to take a breather and move away from all the tweets, updates, texts and calls. Do this by scheduling a specific time-out on your iPhone. Just go to Settings -> Notifications and tap Do Not Disturb. Then, schedule a time when you don’t want to receive any notifications. You can also cherry-pick some people who will be allowed to contact you even during the time range you scheduled!
