The iPhone is one of the most beloved smartphones in the world, known for its stunning design, intuitive interface, and reliable performance. However, like any electronic device, it is not immune to issues. One common problem that many users face is when the top half of their iPhone screen stops responding to touch. This frustrating situation can significantly hamper your ability to use your phone effectively. In this comprehensive article, we will explore the various reasons why the top half of your iPhone screen might not be working and how to troubleshoot and potentially resolve the issue.
Understanding the Symptoms
Before delving into the potential causes and solutions, it’s essential to identify the symptoms that indicate the top half of your iPhone screen is not functioning. Users may notice:
- The touchscreen is unresponsive in the top half of the display.
- The status bar and notification icons are not accessible.
- Apps that require interaction with the upper part of the screen are difficult or impossible to use.
Understanding these symptoms is critical as it can help you pinpoint the issue and find the right solution.
Common Causes of Screen Malfunction
There are several reasons why the top half of your iPhone screen might stop working. Some of these causes are hardware-related, while others could be linked to software issues. Below, we outline the most common reasons for this problem.
1. Hardware Damage
One of the primary reasons the top half of your iPhone screen might not respond is due to hardware damage. This can occur due to various factors:
A. Physical Damage
Physical impacts, such as dropping your phone or exposing it to liquids, can cause internal components, including the touchscreen digitizer, to malfunction.

Occasional bugs within iOS can result in temporary malfunctions, including touchscreen issues. This can occur after an update or installation of new applications that conflict with existing software.
B. App-Specific Issues
Sometimes, specific applications may have glitches that affect how the touchscreen responds, particularly in the upper part of the screen.
3. Screen Protector or Case Problems
If you have a screen protector or case installed, it may interfere with the touchscreen functionality. A poorly fitted screen protector can block the sensors essential for touch recognition.
Troubleshooting Steps to Diagnose the Issue
When faced with the frustrating problem of a non-responsive screen, there are several troubleshooting steps you can take before seeking professional help. Below is a methodical approach to diagnose the issue.
1. Restart Your iPhone
Sometimes, a simple restart can solve temporary software glitches. To restart your iPhone:
- Press and hold the side button and either volume button until the slider appears.
- Drag the slider to turn off your iPhone.

- Select Software Update.
If an update is available, follow the on-screen instructions to install it.
3. Remove Screen Protector and Case
If you have a screen protector or case, remove them to see if they are causing the touchscreen issues. Sometimes a case may misalign the screen or a screen protector may trap air bubbles, hindering touch recognition.
4. Reset All Settings
If the problem persists, consider resetting all settings to clear any software conflicts while keeping your personal data intact. Here’s how to reset all settings:
- Open Settings.
- Select General.
- Scroll down and tap on Transfer or Reset iPhone.
- Tap Reset and choose Reset All Settings.
You will need to re-enter Wi-Fi passwords and preferred settings, but your data will remain safe.
5. Conduct a DFU Restore
If previous steps haven’t resolved the issue, you may need to do a Device Firmware Update (DFU) restore, which is the deepest type of restore. Here’s how to perform a DFU restore (please back up your data first):
- Connect your iPhone to your computer and open iTunes or Finder.
- Put your iPhone into DFU mode by pressing and holding the side button and the volume down button simultaneously for about 10 seconds.
- Release the side button while continuing to hold the volume down button until your iPhone appears in iTunes or Finder.
- Follow the prompts to restore your device.
When to Seek Professional Help
If none of the troubleshooting steps resolves the issue, it may be time to seek professional help. Here’s when you should consider visiting a repair center:
1. Physical Damage is Suspected
If your iPhone has visible signs of physical damage (such as cracks, chips, or liquid exposure), getting it checked by a professional is advisable. Attempting to repair this at home could worsen the problem.

What could cause the top half of my iPhone screen to stop working?
There are several potential reasons why the top half of your iPhone screen may not be responding. Physical damage is one of the most common causes, such as a drop that has impaired the touch sensitivity or internal components. Additionally, water damage can significantly affect screen functionality, leading to unresponsive areas. Over time, wear and tear may also contribute to screen issues.
Another possibility is software-related problems, such as glitches that can occur after an iOS update. If your iPhone is experiencing issues due to app conflicts or temporary system errors, this could manifest as unresponsiveness in certain parts of the screen. Restarting your device can sometimes resolve these software glitches.
How can I tell if the problem is hardware-related or software-related?
To distinguish between hardware and software issues, start by performing a simple restart of your iPhone. If the problem persists after a restart, consider checking for any available software updates. Installing the latest iOS version may fix any underlying software glitches. Moreover, you can test the touch sensitivity by using apps or features that require input in the unresponsive area; if they do not respond, the issue might be hardware-related.
If the software checks out and the problem remains, inspect your device for any visible signs of damage or issues that might indicate hardware malfunctions, such as a cracked screen or exposed parts. Running diagnostic tests through Apple Support or visiting a service center can also help determine the nature of the issue more specifically.
What steps can I take to try fixing the screen issue myself?
Start by restarting your iPhone, as this simple action can often rectify minor software problems. Ensure that your device is updated by navigating to Settings, then General, and selecting Software Update. If there is an update available, download and install it. You may also want to reset all settings by going to Settings, selecting General, and then Reset, but note that this will erase customized settings without deleting your data.
If these steps do not resolve the issue, consider performing a factory reset as a last resort. Make sure to back up your data before doing so. If the problem still exists after a reset, it is likely a hardware issue that will require professional repair.
Should I be concerned about data loss when resolving this issue?
Data loss can be a concern, especially when performing actions like factory resets or updates. If you suspect your iPhone might have a software issue, it’s best practice to back up your data frequently using iCloud or iTunes. This will ensure that your contacts, photos, and other important information are safe and can be easily restored if needed.
In the event that hardware repair is necessary, most professionals will attempt to preserve your data. However, there’s always an inherent risk when dealing with hardware malfunctions. Regular backups will minimize the impact of potential data loss during repairs or troubleshooting.
When should I seek professional help for this problem?
If basic troubleshooting methods such as restarting your device or updating the software do not solve the issue, it may be time to seek professional help. Additionally, if you notice any physical damage to your iPhone or if it has experienced liquid exposure, it’s advisable to consult a technician right away. Ignoring these signs can lead to more extensive damage that could amplify repair costs.
You should also seek professional assistance if you are not comfortable with performing software resets or diagnostic tests. Visiting an Apple Store or an authorized service provider can provide access to more advanced tools and knowledge, ensuring that your device receives proper care and diagnosis.
Will repairing the top half of my iPhone screen be expensive?
The cost of repairing the top half of your iPhone screen largely depends on the model of your device and the extent of the damage. For recent models, screen repairs can be more expensive, but official repair services may offer warranties and guarantees that unofficial technicians do not provide. Generally, costs can range from a reasonably low fee for minor fixes to higher expenses for comprehensive repairs.
If you’re concerned about repair costs, it’s wise to compare quotes from several service providers and check if your device is eligible for warranty coverage. Sometimes, AppleCare or similar protection plans can reduce repair expenses significantly, making it worthwhile to explore these options before committing to a repair.
