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.
