Problems with red screen flashing, hearing calls, and more
Problem: Red screen
A number of iPhone 6 and 6 Plus owners have reported a problem in which their iPhone’s display goes — or flashes — red before showing the Apple logo. Sometimes the problem goes away on its own and returns later, and sometimes it sticks around and the display refuses to turn off.
- Try simultaneously holding down the Sleep/Wake button and the Home button for 10 seconds, or until you see the Apple logo. In some cases, the iPhone will restart normally, but the problem might come back.
- There’s a possibility that this is a software issue, perhaps pertaining to a corrupted backup. You can try the restore process to fix it. Hold down the Sleep/Wake button to turn your iPhone 6 off. Make sure that your computer is running the latest version of iTunes and plug your iPhone in with a USB cable. Now, simultaneously hold down the Sleep/Wake and Home buttons for a few seconds, and when the device comes on, let go of the Sleep/Wake button while continuing to hold down the Home button. You should get the Connect to iTunes screen and you can let go of the Home button. Then, follow the restore procedure through iTunes.
- It’s also possible that this is a hardware failure of some kind, and in that case, you’re going to have to contact Apple or visit an Apple Store and arrange a replacement. It might be a good idea to record the red screen using another device, just in case your iPhone 6 works normally when you take it in for an assessment.
Glitch: Enlarged image or icons filling screen
It’s fairly common to hear reports about enlarged images or icons on the iPhone screen making it difficult for people to see properly or navigate. There’s a good chance that this has been caused by the accessibility feature, Zoom, and it’s easy to fix.
- Hold three fingers together and double tap the screen and you should see things return to normal.
- To make sure that it doesn’t happen again go to Settings > General > Accessibility and turn Zoom off.
Issue: Can’t hear during calls
Quite a few people have run into an annoying issue where they can’t hear the other caller during a phone call. They can make and receive calls as normal, but they can’t hear the person on the line, or they sound muffled even when the volume is turned up.
- Try using the Volume up button and make sure that the ringer volume appears on screen when you press it and not headphones.
- Make sure that nothing is covering the speaker. A screen protector, a case, or even dust can have a big impact. Use a brush or blow gently into the speaker to make sure it’s free of any blockages.
- Make sure that you don’t have anything plugged into the headphone port. It can be worth plugging in headphones and taking them out again just to test if that helps.
- Try turning Bluetooth off via Settings to make sure that you aren’t connected to a headset or car system. If you regularly use a Bluetooth device try connecting to it and then disconnecting to see if it makes a difference.
- You could try going into Settings > General > Accessibility and make sure that Phone Noise Cancelation is turned off, some people have found that this helped.
- Try toggling speakerphone on during a call and see if the issue persists.
- After you’ve tried the solutions above, hold down Sleep/Wake and Home together for 10 seconds until you see the Apple logo to reset the iPhone 6.
- If you’re still having the problem after trying all of these potential solutions then it’s time to talk to Apple and/or your carrier.
Problem: iPhone 6 won’t charge
- Make sure that you are using the cable and wall charger that came with your iPhone 6 or iPhone 6 Plus. If the charger or cable you’re trying to use isn’t Apple certified, then that could be your problem right there.
- Try using a different wall socket, a different cable, and a different charger.
- Take a look at the connector on your cable and the port on your iPhone. Make sure that they’re clean and free of dust. You can blow into the port to clean it out or use a brush with soft bristles.
- There are reports that if you keep your Lightning cable in a humid or wet environment the connector can get corroded. If it’s wet then you should never plug it in because you could also damage the port on the iPhone. If it looks corroded or there’s something on the connectors that you can’t remove with a microfiber cloth, then it’s worth taking the cable into an Apple Store to show them, they may just give you a replacement.
- Try resetting your device while it’s plugged into the charger by holding down the Sleep/Wake and Home buttons for 10 seconds or so until the Apple logo appears.
- There’s a chance that your battery is on its last legs. Take your iPhone into an Apple Store and ask them to take a look.
Glitch: No SIM card error
- Try toggling Airplane mode on and off again.
- Restart your iPhone by turning it off and on again.
- If you recently inserted the SIM card and started getting the error, then there’s a chance it’s damaged or dirty. Try popping it out and taking a look. You can use a pencil eraser to clean the gold contacts and then blow away the debris before putting it back on your iPhone.
- If you’ve dropped your iPhone 6, or it was damaged somehow, then there’s a chance the SIM tray is loose. Some people have had success by putting a small, thin piece of packing tape on the back of the SIM card and then re-inserting it.
- Make sure that your software is fully up to date via Settings > General > About.
- Try the SIM card on another device if you have a compatible device, or try a different SIM card in your iPhone 6.
- If the problem persists then contact your carrier or Apple.
