Reasons Why an iPhone Screen Darkens

The world-famous iPhone from Apple uses a glass touchscreen with a liquid crystal display (LCD) for most of its main functions. Almost every activity on the phone require users to swipe, press, tap, and pinch the screen. But heavy users beware: the screen may not hold up good due to wear and tear. One of these problems is the screen going dark – and sometimes, the users are left scratching their heads in confusion.

• Brightness settings. A bit pretty obvious, don’t you think? Check if the phone’s brightness settings have been decreased first. This is a fairly simple remedy to something that doesn’t normally require a repair.
• Auto-brightness. Later versions of the iPhone come equipped with an auto-brightness function. The device automatically adjusts the screen’s brightness based on ambient light; so if you own a later model, check this option first.
• Screen failure. This is the real deal. If you’ve checked both brightness settings and auto-brightness features but there’s still a dark screen before you, call an iPhone repair specialist as soon as possible. Do not panic if the screen goes caput, the phone itself may still be okay – only the screen’s parts may have problems.

You may also try troubleshooting your phone. First, try resetting your phone by pressing on the sleep/wake button until a red slider appears for a restart. If this doesn’t solve the problem, try a full restore using iTunes’ “restore” button when you connect it to your PC.
