Hi there! I understand you're experiencing an issue where the FOX 4 Dallas app goes black when you tap on it. Let’s work together to resolve this.

First, can you let me know if this is happening only with the FOX 4 app, or are you experiencing similar issues with other apps as well? Additionally, when did you first notice this problem?

In the meantime, here are a few steps you can try:

1. Force Close the App:
- Swipe up from the bottom of the screen (or double-tap the home button if your iPhone has one) to view all open apps.
- Find the FOX 4 app and swipe it up to close it completely.
- After that, try reopening the app to see if that resolves the issue.

2. Check for App Updates:
- Open the App Store and tap your profile icon at the top right.
- Scroll down to see if there are updates available for the FOX 4 app. If you see an update, go ahead and install it.

3. Restart Your iPhone:
- Sometimes a simple restart can resolve temporary glitches. Hold down the power button until you see "slide to power off," then slide to turn it off. After a minute, turn it back on.

4. Reinstall the App:
- If the issue persists, you might want to try uninstalling and then reinstalling the FOX 4 app. Press and hold the app icon until it shakes, tap the "X" to delete it, and then reinstall it from the App Store.

Let me know how these steps work for you, and we can proceed further if necessary!
