iPhone users relish the intuitive interface and seamless experience these devices provide. However, encountering lines on the screen can be an alarming and frustrating situation, as it hampers the clarity and functionality of the device. While such a glitch might seem daunting, several strategies and solutions can be employed to resolve this issue.

Understanding the Causes

Lines on the iPhone screen can emerge due to various reasons, such as software bugs, hardware malfunctions, or physical damages. Distinguishing the root cause is pivotal to implementing the most effective solution.

1. Restarting the Device: The Initial Approach

A fundamental step when encountering screen anomalies is to simply restart the iPhone. This can help in resolving minor glitches and refresh the system, potentially eliminating unwanted lines on the screen. It’s quick, easy, and can surprisingly be effective in many instances.

2. Updating the Software: Rectifying Bugs

Outdated software can often lead to graphical glitches. Ensure that your iPhone is running the latest version of iOS. Navigate to Settings > General > Software Update and install any available updates to rectify potential software-related screen issues.

3. Resetting All Settings: A Fresh Start

If a software update doesn’t rectify the issue, resetting all settings might be the next viable option. This won’t erase your data but will return settings like wallpaper and ringtones to their default states. Navigate to Settings > General > Reset > Reset All Settings to perform this action.

4. Examining for Physical Damage: A Closer Look

Physical damage to the screen or internal components can also lead to lines appearing on the display. A thorough examination of the screen for any visible damages, cracks, or deformities is essential. If damage is apparent, seeking professional assistance is imperative.

5. Seeking Professional Assistance: Expert Intervention

If the aforementioned steps fail to resolve the issue or if physical damage is detected, consulting with a professional technician or visiting an Apple Store for an accurate diagnosis and appropriate remedy is advised. Professionals can identify whether the issue is due to a faulty display, internal hardware malfunction, or other underlying problems and offer suitable solutions, including repairs or replacements.

6. Backing Up Data: Safeguarding Information

Prior to seeking professional assistance or performing extensive troubleshooting steps, ensure to back up the device’s data to iCloud or iTunes to prevent any loss of important information. It’s a crucial step to avoid potential frustrations stemming from data loss.

7. Employing Third-Party Applications: Caution and Discretion

While several third-party apps claim to resolve screen issues, exercise caution and discretion when using such solutions. Unverified or malicious apps can exacerbate the problem or compromise the security of the device.

8. Adjusting Display Settings: Tailored Solutions

Sometimes, adjusting the display settings like brightness and color balance can alleviate minor screen issues. Experimenting with different settings might reveal a combination that mitigates the appearance of lines on the screen.

9. Evaluating Warranty and Insurance Options: Financial Prudence

Before opting for repair or replacement, review the device’s warranty status and any existing insurance policies to determine eligibility for coverage of repair costs. It can potentially save significant expenses associated with resolving screen anomalies.


Lines on the iPhone screen can substantially diminish user experience, but a systematic approach can effectively address such issues. Starting with basic troubleshooting like restarting the device and updating the software, escalating to professional consultation when necessary, can lead to the identification and resolution of the underlying problem. Backing up data and exploring warranty or insurance options are prudent steps to safeguard against data loss and undue financial burden. By combining caution, diligence, and informed actions, iPhone users can restore the optimal functionality and enjoyment of their devices.
