Common iPhone 7 Problems and How to Fix Them

Having trouble with your iPhone 7? You’re not alone. We’ve gathered real-world problems from users and provided detailed fixes you can try. If your issue isn’t covered, feel free to reach out — just be as detailed as possible, and mention any error messages you’ve seen.

Here’s what we’re covering today:


iPhone 7 Won’t Turn On (Black Screen)

If your iPhone 7 won’t power up and the screen stays black:

Force Restart Your iPhone 7

  • Press and hold the Power button.
  • While holding Power, press and hold the Volume Down button.
  • Keep holding both buttons until you see the Apple logo.

If Force Restart Fails, Try DFU Mode

  • Turn off the phone (let the battery drain if you can’t power it off).
  • Charge for at least 30 minutes.
  • Connect to a computer with iTunes open.
  • Press and hold the Power button for 3 seconds.
  • While holding Power, press and hold the Volume Down button for 10 seconds.
  • Release Power but keep holding Volume Down for another 5 seconds.
  • If your computer says “iTunes has detected an iPhone in recovery mode,” proceed with Restore.

Still stuck? Contact Apple Support to find a service center nearby.


iPhone 7 Vibrates When Playing Music

Feeling vibrations when playing music or videos is normal for the iPhone 7 and 7 Plus. It’s due to how the new stereo speakers and overall hardware are designed. Nothing to worry about unless it gets worse over time.


iPhone 7 Rear Camera Is Blurry After Update

If your rear camera won’t focus after an iOS update:

Reset All Settings

  • Go to Settings → General → Reset → Reset All Settings.
  • Enter your passcode if needed and confirm.

If that doesn’t help:

Factory Reset

  • Settings → General → Reset → Erase All Content and Settings.
  • Backup your files first!

If the camera is still blurry, it might be a hardware issue. Contact Apple Support.


iPhone 7 Only Plays Sound in One Earbud or Car Speaker (Bluetooth)

Check Mono Audio Setting

  • Go to Settings → Accessibility → Audio/Visual.
  • Make sure Mono Audio is turned OFF.
  • Also check the left/right audio balance slider and center it.

iPhone 7 Won’t Record Videos Longer Than 7 Seconds

If your videos stop recording after a few seconds:

Factory Reset Your iPhone

  • Settings → General → Reset → Erase All Content and Settings.
  • Backup everything first.

If the problem persists, you’ll likely need help from Apple.


iPhone 7 Wi-Fi Symbol Missing (Only LTE Showing)

If you’re connected to Wi-Fi but only see LTE:

Full Restore Through iTunes

  • Connect your iPhone to a computer with iTunes.
  • In iTunes, choose Restore iPhone.

This wipes everything and reinstalls iOS fresh. If it still happens, reach out to Apple.


What iPhone 7’s IP67 Certification Actually Means

IP67 means the iPhone 7 is water-resistant, not waterproof. It can survive light splashes or being submerged for a short time (up to 30 minutes under 1 meter of fresh water).
Salt water is very corrosive — if your phone fell into the ocean, it may still develop issues over time. Watch for problems and visit Apple Support if needed.


iPhone 7 Mobile Data and SMS Are Very Slow

If your mobile data is unreliable and SMS takes forever:

  • Check if your signal is weak (1–2 bars).
  • If yes, it’s a carrier/network problem, not a phone problem.
  • Contact your carrier to report the issue or ask about signal boosters.

You can also try a factory reset to rule out device-related software bugs.


iPhone 7 Can’t Edit Facebook Posts in Safari

If Safari won’t let you edit Facebook posts:

  • Reset All Settings via Settings → General → Reset.
  • If that doesn’t help, use another browser temporarily (like Chrome).

This is likely a Safari bug and may need a future iOS fix.


How to Mute Game Sounds While Listening to Music on iPhone 7

You can’t control game and music sounds separately through iPhone settings.

  • You’ll need to mute the game sounds manually inside the app.
  • If the game doesn’t offer in-game volume controls, there’s no built-in iOS fix.

Can’t Lower Media Volume While on a Call on iPhone 7

Same limitation as above. To lower a video’s sound while you’re in a call:

  • Open the app playing the video (like Facebook).
  • Lower or mute the video’s sound from within the app.

iOS doesn’t let you independently control media volume while in a call.
