iPhone 7 Stuck in Boot Loop, Won’t Boot After Water Damage, or Takes Blurry Photos? Here’s What to Do

iPhone 7 problems can show up in all kinds of ways — from boot loops after a screen replacement to blurry photos or even complete failure to boot after getting wet. This guide tackles three common iPhone 7 issues and how to troubleshoot them.


iPhone 7 Stuck in Boot Loop After Screen Replacement

The issue: After replacing the screen (but keeping the original home button for Touch ID), the phone keeps rebooting, doesn’t charge properly, and sometimes shows 1% or 100% battery randomly. Ringer volume doesn’t work, and apps crash when opened.

What to try:

  • Boot loops after a DIY repair usually point to a hardware compatibility issue — something inside isn’t seated correctly or is causing a short.
  • iPhones are picky about internal components. A bad replacement screen, loose connector, or improper grounding can cause reboot loops.
  • Since battery readings are jumping around and it doesn’t charge properly, it’s also possible the battery connector or charging circuit is damaged.

Fix:
Take it to a trusted independent repair shop. A pro can open it up, check for a short or reflow any bad solder joints. If you’re lucky, it’s a simple fix. If not, and the logic board is damaged, it may not be recoverable.


iPhone 7 Plus Won’t Boot After Water Exposure (Errors 4005, 4009, 4013)

The issue: After a drop near a pool, the iPhone 7 Plus won’t boot and is stuck on the Apple logo. Attempts to restore via DFU mode fail with iTunes errors 4005, 4009, and 4013.

What to try:

  • Even if it didn’t get visibly wet, moisture could’ve reached internal components — especially if the screen was previously replaced and water resistance compromised.
  • Errors like 4005 and 4013 usually point to issues with the charging port or other hardware-related problems.

Fix:

  1. Let it dry completely — at least 24 hours in a dry room. If it was exposed to salt water, rinse it first with fresh water, then dry it thoroughly.
  2. Try a DFU restore again once fully dried.
  3. If it still fails and the error persists, it likely suffered logic board damage or corrosion inside.

Best bet? Bring it to a repair technician who can open it up and check for board damage or use pro-level drying equipment.


iPhone 7 Camera Blurry Compared to Older Microsoft Phone

The issue: You expected great camera quality based on iPhone 7 reviews but landscape shots come out soft and blurry compared to your previous Microsoft phone.

What to know:

  • The iPhone 7’s camera is good for its time — especially for close-ups or mid-range shots — but it’s not on par with modern smartphone cameras.
  • Some users find it struggles with landscape sharpness, especially in low light or when zooming.
  • It may not be a defect — just camera performance limitations.

Tips to improve photo quality:

  • Tap to focus before snapping the shot.
  • Avoid digital zoom.
  • Clean the camera lens (even a smudge can blur distant subjects).
  • Use HDR mode for better contrast in landscape shots.
  • Try third-party camera apps that offer more manual control.

If the photos are still disappointing, and you’re sure it’s not a technique issue, it’s worth getting the camera module checked — especially if it was ever dropped.
