Make Your iPhone Yours
The iPhone 4 is designed with customizability to the preferences of the users as a central feature. This works for all of the aesthetic points of the phone, including both the images and the sounds. When coordinating the visuals and audio settings of your iPhone there are a few things to consider.
The brightness of the display on the touch screen needs to be set directly to the way you like to see and how worth the image quality this is. Go into the Settings icon on your iPhone desktop and then select Brightness. If you go here, you will see a bar with very low brightness at one end and then excessive brightness on the other. You can set this anywhere in between these extremes that you want, but remember that the brighter you set it to be the shorter the eventual battery life will be. If you turn on Auto Brightness it will set it for you, but this is often darker than most people want.
The Retina Display on the iPhone 4 creates a seamless kind of clarity that requires you to match your content well, but this also means that you have to avoid interference. Many low end iPhone cases, and even a few reliable ones like the Otter Box, have touch screen protection that can allow for air bubbles to form and can decrease image clarity. When this is coupled with the casual buildup of dust and other particles you will not actually be able to view the screen as intended.
The iPhone comes standard to alert you about almost everything that occurs on it. Since there are so many features to smart phones like the iPhone. This will likely be more than what you want, so you are going to need to adjust your iPhone settings so that it only alerts you when you want. Go into the Settings icon and select Sounds. Here you will see a whole line of on/off switches for different warning alerts. These include things like New Voicemail, New Mail, Sent Mail, Calendar Alerts, and others. You can also adjust the sounds that your ringtone makes and text message alert.
You also have the option to turn off the clicking sound that the keyboard makes when you click each key. This may make it easy to text people in quiet locations, but it is going to make the typing on the phone even more difficult than it already is. Avoid doing this whenever possible.
If you are going to use the onboard speakers in the iPhone, you may need to position the phone correctly. Position your hand behind the phone, cupping the speakers somewhat. This will help optimize the sound coming out. If you can, try to position the iPhone against a wall or in a corner. These are also going to need quite a bit of maintenance over the period of ownership as their position at the bottom often leaves them neglected, and most iPhone 4 cases can actually allow dust to clog this area generally. It is a good idea to spend attention here as well as the plug for your USB connection and battery charge, which can become a major problem if damaged.
