If your iPhone 6s is flashing a blue screen or stuck in an endless reboot cycle, don’t panic—you’re definitely not alone. This issue has affected iPhones since the iPhone 5 era, and even though Apple rolled out updates to fix it, it still pops up on models like the 6s and 6s Plus. Here’s everything you need to know about why it happens—and, more importantly, how to fix it.

Why Your iPhone 6s Might Be Showing a Blue Screen

Common reasons include:

• Software bugs or faulty apps: A glitchy app could crash your system.
• Multitasking overload: Running too many apps at once can overwhelm the processor.
• Memory overflow: Limited RAM can cause crashes if overused.
• Hardware damage: A damaged motherboard, screen connector, or even a wrong screw from a previous repair can cause a BSOD.
• Failed updates or restores: Interruptions during a system update or restore can leave the phone in limbo.

If you recently dropped your phone—even if it looks fine—there might be hidden hardware damage causing the issue.

10 Ways to Fix iPhone 6s Blue Screen or Infinite Reboot

1. Force Restart Your iPhone

This is the simplest first step.

How to force restart:

• Hold down the Home and Sleep/Wake (Power) buttons at the same time.
• Keep holding until you see the Apple logo.

---

2. Restore Your iPhone in Recovery Mode

If a force restart doesn’t work, try restoring via Recovery Mode.

How to do it:

• Connect your iPhone to your computer but don’t open iTunes yet.
• Turn off your iPhone completely.
• Hold down the Home button while connecting it to the computer.
• Keep holding until you see the Connect to iTunes screen.
• Open iTunes (or Finder on macOS Catalina and later) and follow the prompts to Restore.

3. Try Free iOS Repair Tools

If standard recovery mode doesn’t work, use tools like ReiBoot or iMyFone Fixppo to exit recovery mode or fix system glitches without wiping your data.

4. Perform a DFU Restore

DFU (Device Firmware Update) mode is a deeper restore method.

Steps:

• Connect your iPhone to your computer and open iTunes/Finder.
• Turn off the iPhone.
• Hold Power for 3 seconds.
• While still holding Power, hold Home for 10 more seconds.
• Release Power but keep holding Home until iTunes detects the iPhone in recovery mode.

Once in DFU mode, you can restore your iPhone completely.

5. Disable iCloud Sync for iWork Apps

If your iPhone crashes when using Pages, Numbers, or Keynote:

• Go to Settings > Your Apple ID > iCloud.
• Turn off syncing for iWork apps (Pages, Numbers, Keynote).

---

6. Use Only One App at a Time

If you’re opening multiple apps back-to-back, close the ones you’re not using to avoid overloading your phone’s processor.

---

7. Delete Faulty Apps

If the blue screen started after installing a specific app:

• Delete the app.
• Check if the issue stops.
• If it’s critical, reinstall it and check for updates.

---

8. Update to the Latest iOS Version

Apple patches bugs in every update.

• Go to Settings > General > Software Update and install any available updates.

---

9. Hard Reset Your iPhone

If nothing else works and you’re okay losing your data, you can factory reset your iPhone.

Steps:

• Connect your iPhone to iTunes/Finder.
• Select Restore iPhone.
• Confirm and let it erase your device back to factory settings.

Be sure to back up important data first!

10. Contact Apple Support or Your Carrier
