As iPhone repair specialists, we've seen a growing number of issues involving damaged flex cables and cracked iPhone screens during installation. These errors can lead to costly repairs and avoidable headaches. So, we've put together this detailed guide to help you understand how to fit iPhone screens properly, especially for the iPhone X, XR, XS, and XS Max models.
If you're not confident handling the repair yourself, bring your iPhone to us at Imfixed for expert service, professional screen fitting, and peace of mind.
Avoiding Flex Cable Damage During Screen Fitting
One of the most common mistakes we see is incorrect positioning of the flex cable during installation. If the cable isn't properly aligned, it can become trapped when pressing the screen into place. This often results in display malfunction and is not typically covered under warranty. So always take extra care when pressing the screen into the iPhone chassis.
At Imfixed, we follow industry best practices to ensure the flex cables are fitted safely and correctly, avoiding future damage.
Post-Installation Screen Cracks: Vertical Lines & More
Another frequent issue is vertical lines appearing on the screen after fitting. This is usually caused by improper removal of the original screen, particularly when removing the front camera module. It’s crucial to double-check the positioning of the camera bracket after removing adhesive, as even a slight bend can crack your new screen.
We take great care at Imfixed to secure all internal components properly before final assembly, preserving your screen's integrity.
Front Camera Misalignment Causing Screen Cracks
Improper installation of the front camera lens holder can cause it to push against the LCD, leading to cracked screens, especially on iPhone X models. Applying too much pressure during reassembly only makes things worse.
If you're unsure how to align these components, don't risk it. Let our experts at Imfixed handle it for you. We’ve successfully repaired thousands of devices across the UK.
