Step by Step Tutorial to Fix an iPhone that Has Gone Completely Dim

Before we dive into the steps, let’s understand what we hope to achieve here. These steps are designed to troubleshoot and hopefully fix an iPhone screen that has gone dim for various possible reasons, without the need of a professional repair.

Step 1: Check the Brightness Level

First, make sure that the brightness on your iPhone is turned up.

Sometimes, the simplest solutions are the most effective. Your iPhone has a brightness control that can be adjusted manually or set to change automatically based on ambient light. If your screen is dim, it’s possible that the brightness has been turned down accidentally or the auto-brightness feature isn’t working properly.

Step 2: Restart Your iPhone

Next, try restarting your iPhone to see if that brings back the brightness.

Restarting your device can often resolve a multitude of issues, including a dim screen. This action can clear minor software glitches that may be affecting the screen’s performance.

Step 3: Check for Physical Damage

Then, inspect your iPhone for any physical damage that might be affecting the screen.

Dropping your iPhone or exposing it to water can cause damage that leads to a dim screen. If you notice any cracks or signs of water damage, it’s likely that a repair is needed.

Step 4: Update Your iOS

If none of the above steps work, check for an iOS update and install it if available.

Software updates often include bug fixes that can resolve issues like a dim screen. Make sure your iPhone is running the latest iOS version to benefit from these fixes.

Step 5: Reset All Settings

Lastly, if all else fails, try resetting all settings on your iPhone.

This step should be a last resort as it will return all settings to their defaults and may remove some personal preferences. However, it can also clear any settings that may be causing your screen to be dim.

Additional Information

When dealing with an iPhone that has gone dim, it’s also important to consider the age of your device. Older iPhones may start to experience screen issues simply due to wear and tear. In such cases, a professional repair or even a replacement might be necessary. Additionally, if your iPhone is still under warranty or you have AppleCare+, you might want to consider taking it to an Apple Store or authorized service provider for a diagnosis before attempting to fix it yourself.

Another tip is to always back up your iPhone before performing any major troubleshooting steps. This ensures that your data is safe in case something goes wrong. Also, be aware of the lighting conditions in your environment; sometimes, a screen may appear dim in bright sunlight even when the brightness is turned up.
