Troubleshooting iPhone 6 Plus with phone screen flickering issue

To make this article more specific, I’ve intend to highlight an excerpt of an associated problem sent to us by one iPhone 6 Plus owner, saying his iPhone screen randomly flickers and somehow behaves oddly.

“All of a sudden my iPhone 6 Plus began to freeze, open up apps on its own, scrolling pages, and the screen flickers. This happens randomly. I’m sure it has never been exposed to water or liquids. Will you be able to help me fix it?”

What could possibly cause your phone screen flickering issue?

Device issues are categorized into two types — software-related and hardware-related. Software-related issues have a higher chance of getting resolved by user-defined workarounds compared to issues linked to hardware. The latter often requires professional aid to get your device fixed. In some cases, an iPhone screen may flicker, freeze, or become unresponsive due to some settings that are misconfigured or certain apps suddenly went rogue.

Basing on the given problem statement, it’s a bit hard for us to determine if the problem is due to a faulty hardware or software. Although the user has said that the device was not exposed to water/liquid, he failed to state if there’s any instance when the phone fell or was dropped. For this reason, I’ve decided to demonstrate all possible workarounds applicable for software- and hardware-related screen issues on the iPhone 6 Plus.

Recommended Solutions for iPhone 6 Plus screen problems

After digging through some forums threads and posts, I’ve managed to come up with the following list of recommendations to anyone who is having similar problems with their iPhone 6 Plus screen, as described in the aforesaid problem statement.

You may try any of these methods to fix screen flickering, freezing, and unresponsive touchscreen on your iPhone, whatever you think is best applicable to your situation.

Important Note: Be sure to test your device after completing each of the following troubleshooting steps to see if the problem is fixed. Proceed to the next step(s), if necessary.

Screen problems associated with faulty software or corrupted applications can be rectified by performing any of the following procedures:

Step 1: Restart your iPhone. Most of the time, small bugs can easily be fixed by a simple reboot on your phone. Hold down the Sleep/Wake button and Home buttons simultaneously until the Apple logo appears.

Also ensure your phone has sufficient battery power and that the battery is not damaged as these too could trigger your screen to act weird.

Step 2: Configure Display settings. Some iPhone users who have experienced similar screen problems on their device fixed them by reducing the screen brightness.  You can also try to disable auto-brightness and see what happens.

To make your iPhone 6 Plus screen brighter or darker, slide your finger up from the bottom of the screen (from any screen). This will open the Control Center. From there you can touch and drag the slider to manually adjust screen brightness.

Alternatively, you can go to the Home screen, select Settings-> Display & Brightness-> Turn off Auto-Brightness. And finally, set the brightness by dragging the slider under Brightness.

Step 3: Enable Reduce Transparency feature. For iPhone’s running iOS 9 this option can be accessed through Settings-> General-> Increase Contrast-> and then tap the switch next to Reduce Transparency to turn it on.

Note: Menu options may vary depending on the iOS version your device is running on and also by carriers.

Enabling this feature would make the text on your device a little more legible. It’s a temporary workaround utilized by some users who have problems on unresponsive touchscreen and random flickering on their iPhone display.

Step 4: Check memory (RAM) status. Frozen and unresponsive displays are common indicators of a memory issue, particularly insufficient memory on your device. To make sure this is not causing the problem, check your iPhone and make sure its internal memory storage is good enough to carry out more processes.

Step 5: Factory reset your iPhone. This should be your last resort. Performing this method will not only require more time but also wipes your iPhone data while restoring it to factory default settings. Therefore, it eliminates the likelihood about the screen problem being caused by corrupted software.

If none of the aforesaid workarounds have done well, and the screen problem persists, then most likely the hardware is to blame. Considering this is your case and that your iPhone is not in warranty anymore, performing the following methods might be helpful.

  1. Ensure your iPhone screen is clean. Dirt or dust accumulated on your phone’s display may also result to display issues including unresponsive touchscreens. Thus, keep your iPhone screen free from dust or dirt.
  2. Replace LCD screen. Screen problems like flickering, frozen or unresponsive touchscreen could be due to a defective LCD. If you’re capable enough of replacing your iPhone’s LCD screen by yourself, then you may purchase and replace it with a new one.

If both the old and new screens are showing the exact same problem, it’s possible that some circuit board components, including the touch circuit, touch connector and the touch IC, are damaged. Oftentimes, these cases can be rectified by re-flowing or re-soldering both the touch connector on the board and the touch IC.

You can also try to test different screens (if available) to determine which screen is not working. But then again, all these would require specialized soldering tools and lots of skills to produce positive results. Otherwise, you can just take your iPhone to an authorized Apple technician for damage check and repair.

  1. Replaced the battery, upon reassembling, found that the screen flickered. Now have vertical lines and flickering. A new battery, and checked connection. Still have the flickering.

  2. After buying 3 IPhone models now I’ve noticed their life expectancy is only about 2-3 years where fault like these start happening…. correct me if I’m wrong maybe just maybe…… Apple only give them this life span so your forced to buy the next model?!?

  3. my iPhone 6 Plus, purchased in November 2014, started to act up in February this year. It would turn itself on, take pictures, jump from app to app, make phone calls, make FaceTime requests and any attempt to stop any of these situations resulted in long strings of gobble-dee-gook. Attempts to turn the phone off were usually unsuccessful because the onscreen “Slide to turn off” was unresponsive. After being left alone for a short period it acted as it should and Settings/General/Reset was accessed and a hard reset usually resulted in the phone working properly again but not for long. I contacted Apple Care on several occasions only to be told that the problem was caused by repeatedly dropping the phone on a hard surface and i should take it to an Apple Store or Authorized Service Centre where I could pay CA$229 to have the touchscreen replaced. The fact that Apple would only provide a 90 day warranty on the new screen caused my skepticism about that solution. Obviously Apple was not all that confident that replacing the screen would resolve the issues. After researching the problem on the Internet it became apparent that there is an issue with the Touch IC chips that results from the flexing of the case. I have joined the Class Action suits launched here in Canada and in the United States because Apple has decided not to match the honourable reaction by Samsung when their battery issue became widespread. So much for corporate responsibility and accountability despite Apple having billions of their customers’ dollars sloshing around in foreign bank accounts.

  4. Hey guys if anyone is viewing this my iPhone 6Plus has had the same issues (Gray bar at top, screen flickering, etc…). However, I went into the display settings and turned UP my brightness and disabled the auto brightness feature. My phone has no issues now for some reason. This fix worked for and may not work for you, but I recommend taking a look at your display settings.

  5. My iPhone 6 plus started flickering right after I upgraded to iOS 11.0.2. I thought the problem was due to the upgrade but then I found that some iPhone 6 Plus can have a hardware problem known as “touch disease”. Apple claims this is caused by dropping the phone but others say it is due to faulty chips: Regardless, Apple will repair your iPhone 6 Plus for $149 if the screen is flickering or it has multi-touch issues: There are class action suits about this problem. Well, I thought the flickering was due to a hardware problem but now that I have upgraded to iOS 11.0.3, the problem seems to have disappeared. I see that iOS 11.0.3 addresses iPhone 6s screens but there is no mention of the iPhone 6 Plus.

  6. My phone flickered and the touch screen completely stopped working. Verizon just sent me a new refurbished phone. After setting up the new phone with all of my apps etc. it started flickering and freezing up. I deleted a couple of new apps I had loaded in the past 2 weeks and rebooted my phone, adjusted the brightness and shut off the auto brightness. It is still happening. Thoughts on this? My phone is a 6 plus. Now I don’t know if it’s it the refurbished phone or a software problem?

  7. My iPhone 6 kept freezing up at random times. I would have to do a hard reset most times. I tried just about every fix most people said to do with no luck. I took my phone apart and disconnected the battery, then with the battery still disconnected push the power button and hold it down for several seconds. Then reconnect the battery and put it all back to together. Glitch-free ever since.

  8. My IPhone 6+ flickered whenever I placed a call on the iPhone and rendered the iPhone useless and unable to respond to any commands except for pushing both buttons for a shutdown. However, I was able to use my car’s command system to answer, dial and hang up after the calls. After backing up my phone I tried the first fix. I simply swiped up and adjusted the brightness to the right. I then placed a call and everything worked properly. Thanks for saving my IPhone 6+.

  9. I have a I phone 6plus the top of the screen randomly starts to flicker a gray line that flickers and travels to the middle of my phone `and the touchscreen is unresponsive I’ve had restarted the phone several times but when it comes on my phone automatically opens different apps. I took my phone in for repairs to the sprint store however I Don’t have insurance and they advise me to purchase a new phone. I can’t afford a new devise I’m still making payment on my defected phone. *Apple needs a Low coast repair option for this problem… Please please help!

  10. How am I make these trial adjustments to my phone if it is frozen? I literally cannot slide Theo on to power off my phone nor access the settings. I haven’t dropped my phone nor gotten it wet, and I’m having the same issues. Let me know, if anyone has any further advice, thanks.

  11. If your phone is on charge,especially a non official charging cable,and your screen is shaking unplug the cable and check it again. Mine shakes when it’s charging on a After market cable but doesn’t any other time… just sharing this weird scenario

  12. Awesome it worked. Thank you
    Auto-Brightness was the cause. Thank you so much.
    I thought my phone was done. New life for the phone.

  13. Mine does this all the time and to get it to worm i have to bend the phone a little bit as its near enough unusable! i have not tried factory resetting yet as i do not want to do it and it not work all over again or become worse.. could anyone get back to me saying if it works or not?

  14. I have a 6plus 128gb that was becoming unusable due to flicker and random selections & lockups. I did a full factory reset, cleaned the phone, replaced the glass screen protector all to no avail. Following your guide I checked the software apps installed and saw a corrupted line on an old game. Deleted this and took auto brightness off and all resolved. I was just about to buy a new phone! Thank you so much. Note if software etc corrupt it seems to get restored on factory reset so manual checks etc as suggested are important.

  15. I have faced similar problem after I have changed my screen. the original screen was broken and I have changed it with a new screen which is not from apple. now it is acting wired. I have reassembled two for the second time but no change. do you think the problem is the faulty nature of the secreen?

  16. My resolves itself if I bend the screen slightly, which can’t be a good thing. I will try all of the options and see if it resolves anything.

  17. Hi I want to know that my Iphone6 plus got slipped from my hand and it is left with a Brocken touchscreen and irresponsive touch !
    I have been reported that its because of the failure of ic track .
    I dn know exactly what to do with it.
    Help me asap

    Need help!

  18. All I did was unplug my phone and it stoped flickering. I think this has something to do with how hot the charger was and it may have been tapping stuff near the bottom of the screen. I saw a video where a guy tazzed a phone near the home button and it flickered a tone, but when he stopped it worked normally. So if you are charging your phone, try unplugging it.
