The Mystery Behind Half a Non-Functional iPhone Screen

Diving into the technological age, iPhone users are often left puzzled when faced with the peculiar phenomenon of half their screen not working. This anomaly, although frustrating, can have varied explanations ranging from software glitches to hardware malfunctions. Here’s a deep dive into understanding why this occurs and the potential solutions to alleviate such vexing occurrences.

Diagnosing the Issue: Software or Hardware?

The first step is distinguishing whether the problem stems from software-related issues or hardware malfunctions. Software problems are usually more user-friendly to resolve, typically requiring some tweaks or updates, while hardware issues might necessitate professional intervention or even replacements.

Things To Try

Here are some things to try if half of your phone screen doesn’t work:

  • Restart your phone. This may seem like a simple solution, but it can often fix minor software glitches.
  • Check the screen protector. If you have a screen protector on your phone, remove it and see if that fixes the problem. A damaged or poorly applied screen protector can cause the screen to malfunction.
  • Clean the screen. Sometimes, a dirty screen can cause it to malfunction. Clean the screen with a soft, damp cloth.
  • Calibrate the touchscreen. To do this, go to your phone’s settings and search for “touchscreen calibration.” Follow the instructions on the screen to calibrate the touchscreen.
  • Boot into Safe Mode / Recovery Mode. This will disable all third-party apps and allow you to see if the problem is caused by a third-party app. To boot into safe mode, press and hold the power button until you see the power off menu. Then, press and hold the volume down button until you see the safe mode option. Tap on the safe mode option to boot into safe mode.
  • Reset your phone. This should be a last resort, as it will erase all of your data. To reset your phone, go to your phone’s settings and search for “reset.” Follow the instructions on the screen to reset your phone.

Software Glitches and Bugs

iPhone screens may partially become non-responsive due to software glitches. Running an outdated iOS or having bugs in specific apps can lead to such issues. Regularly updating your iOS and apps ensures that any recognized bugs or glitches are rectified, minimizing the likelihood of screen anomalies.

The Role of Third-Party Apps

Sometimes, the installation of third-party apps can interfere with the normal functioning of the screen. These apps might not be optimized for the iOS platform, causing conflicts and disruptions. Identifying and removing such applications can often restore normal screen functionality.

Hardware Malfunctions

While software glitches are commonplace, hardware malfunctions present a more grave concern. Physical damage, component failures, or manufacturing defects can lead to half of the iPhone screen not working.

Physical Damage

A common culprit for hardware malfunction is physical damage. Dropping the iPhone or exposing it to harsh conditions can damage the internal components, affecting the screen’s responsiveness. Professional assessment is crucial to understand the extent of the damage and the necessary reparations.

Internal Component Failure

Even without visible physical damage, internal components like the screen’s digitizer can fail, impacting the screen’s performance. A faulty digitizer, responsible for translating touch into digital signals, can render parts of the screen unresponsive. Replacements or repairs are usually needed in such scenarios.

Manufacturing Defects

Occasionally, manufacturing defects can slip through quality checks, causing screen anomalies. In such instances, seeking warranty support or replacements from Apple is usually the most efficient remedy.

Proactive Solutions and Precautions

Beyond reactive solutions, adopting proactive measures can prevent screen malfunctions and prolong the device’s life.

Use of Screen Protectors

Implementing a high-quality screen protector can shield the screen from potential damage, reducing the risk of responsiveness issues due to physical impacts.

Regular Device Maintenance

Regularly maintaining and cleaning the iPhone, ensuring it’s free from dust and debris, can prevent unnecessary damages and enhance the longevity of the device.

Responsible Handling

Being mindful and cautious when handling iPhones, avoiding drops and impacts, can protect the device from damages that can lead to screen anomalies.

Professional Advice and Repairs

When faced with a non-responsive screen, seeking professional advice is paramount. Authorized service providers can offer accurate diagnostics and solutions, ensuring the correct resolution of the issue, whether it requires software adjustments or hardware repairs.


The phenomenon of having half of the iPhone screen not working can be perplexing and inconvenient. However, understanding the potential causes, whether they are software glitches or hardware malfunctions, is crucial in seeking the appropriate solutions. Adopting proactive measures and responsible handling can minimize the risks, and seeking professional advice ensures the longevity and optimal functioning of the device.


  1. Can software updates resolve screen anomalies? Software updates can rectify recognized glitches and bugs that might be causing the screen to malfunction, making them a vital step in troubleshooting screen issues.
  2. How can third-party apps affect screen functionality? Third-party apps, if not optimized for iOS, can cause conflicts and disruptions, potentially impacting screen responsiveness.
  3. Is a non-responsive screen indicative of physical damage? While a non-responsive screen can be due to physical damage, it can also result from software glitches, internal component failures, or manufacturing defects.
  4. Can screen protectors prevent screen malfunctions? Screen protectors can shield the screen from physical damage, which can, in turn, reduce the risk of screen malfunctions due to impacts.
  5. When should professional advice be sought for screen issues? Professional advice should be sought whenever troubleshooting steps like software updates and app removals fail to resolve the screen anomalies, or when there is visible physical damage.
