Phone Reboots When Receiving Calls After Screen Replaced
Phone Reboots When Receiving Calls After Screen Replaced

If you’ve just had your phone screen replaced and you are getting reboots every time you receive a phone call, the replacement could definitely be the issue. What exactly is wrong could range from a faulty replacement screen, poor workmanship on the repair process, a short that may have been created (or at least made worse) during the repair process, etc. The best thing to do in a case where this is happening to you is to immediately take your phone back to the shop that repaired it (if you had it done for you) and have them look into the issue. Oftentimes this can be fixed without much hassle. But what if you were the one that replaced the screen? Let’s analyze some of the reasons why a phone would reboot during calls post screen replacement and explore potential solutions.

Understanding the Connection

Modern smartphones are marvels of technology, with intricate designs and complex functionalities. At first glance, it might seem odd that a screen replacement could affect phone calls. However, these devices are interconnected in ways we might not always realize. A small change or disruption in one component can have a ripple effect, leading to unexpected issues.

Potential Causes of the Reboot Issue

  1. Faulty Screen Replacement: Both our research and discussions on platforms like iFixit highlight that not all replacement screens are created equal. A subpar screen or improper installation can lead to various issues, including rebooting during calls.
  2. Damaged Internal Components: The trauma of a fall can damage more than just the screen. Internal components might be affected, leading to unexpected reboots. Sometimes, the impact that cracked the screen might have also damaged other internal components, manifesting in various ways.
  3. Software Conflicts: Software plays a crucial role in the functioning of our phones. Sometimes, the issue isn’t hardware-related at all. Software conflicts or bugs can cause rebooting, especially during resource-intensive tasks like phone calls. Some users on Apple Discussions pointed out that software issues could also lead to this problem.

Troubleshooting the Problem

1. Check the Screen Installation: Ensure that the screen is correctly installed. Even a minor misalignment can cause significant issues. If unsure, consider getting it checked by a professional.

2. Inspect for Internal Damage: If the phone experienced a significant fall or if you suspect any internal issues, it’s worth getting it checked by a professional.

3. Update Your Software: Keeping your phone’s operating system and apps up-to-date is crucial. Software updates often contain bug fixes that can resolve various issues.

4. Monitor Home Button and Other Components: Issues with the home button (if your phone has one), especially if replaced, can lead to the phone restarting. The home button is coded to the phone, and using a non-original one can cause issues.

5. Pull out and re-seat everything: If there was a short created during the repair process pulling the components out and re-seating them may resolve that. Additionally you might notice a screw in the wrong place or something that shouldn’t be there that can be resolved.

6. Re-do the screen replacement with a new screen: This could lead you down a frustrating road of RMAs and re-tries, but if the screen is faulty you’ll need to replace it. If you still have the old screen you might want to try that first – re-install it to see if you can get the reboot behavior to go away. If you don’t have the old screen, purchase a new one to rule out the fact that the one in there might be the cause of your issue.

7. Get professional help: This problem is one of those that most repair shops can handle and have seen before. If you’ve tried everything you can try, take your phone into a professional cell phone repair shop close to you to see if they can debug it.

Preventing Future Issues

  1. Invest in a Quality Phone Case: A sturdy case can prevent many falls and subsequent damages.
  2. Choose Reputable Repair Services: Always opt for reputable repair services that use high-quality replacement parts.
  3. Regularly Update Your Phone: Keeping your phone updated can prevent many software-related issues.

Whether it’s a hardware or software issue, understanding the root cause is the first step towards a solution. With the right precautions and regular maintenance, you can ensure that your phone remains in optimal condition.
