iPhone 6 Plus freezing up and screen keeps flickering, other screen issues

Screen problems is one of the most frustrating problems an #iPhone user can encounter. Today, we cover 3 #iPhone6 screen problems taken from reports submitted by some members of our community. We understand some of you may expect a permanent solution to your screen issues but be reminded that we don’t fix hardware troubles. Fixing hardware problems is way more complicated than solving software-related ones. In most cases, hardware repair by amateurs tend to result to more problems than solutions so we leave anything that requires hardware component replacement or in-depth diagnosis to someone who can physically check the device. So, for those expecting to find step-by-step guides to, say, replace a screen, or arrive at a conclusion that a particular component is bad, simply skip this article.

If you are looking for solutions to your own #iOS issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: iPhone 6 Plus freezing up and screen keeps flickering

My phone is flickering and freezing up. I took it to an iPhone repair they wouldn’t even look at it. He said it’s a faulty chip and Apple knows about it and continues to sell the phone. It is a little over a year old. PLEASE help me! I cannot afford a new phone. I am a school teacher. It is not very honest of your company to know about this problem and not correct it. I’ve read numerous cases about this and talked to several people who got NO help from the Apple support. I do not drop my phone. I purchased from the local AT&T store a good case and an expensive screen for my Apple iPhone 6+. Now I may have to go back to using my iPhone 4 that I used for over 6 years with NO problems! Please help me! I”ve tried the ‘tricks’ on your website for troubleshooting–except the factory reset. — Michelle

Solution: Hi Michelle. First of all, we are not, in any way associated with Apple. We don’t work for them, nor do we endorse their products. We’re here to share our expertise in providing software solutions for iOS devices and nothing more.

Secondly, we NEVER said we know of this problem and chose not to tell users. Whatever made you say that should be kept to yourself. If a third party repair shop told you that, ask them to give you what specific chip is problematic so we can raise the issue up to Apple support. With millions of iPhone 6 and iPhone 6 Plus being used around the world, it’s unavoidable to have some few bad “apples” out there. As far as your claim about Apple knowingly manufacturing  iPhone 6 and iPhone 6 Plus devices using defective components is concerned, we say it’s unfounded. We know of a few instances wherein Apple acknowledged some batches of their iPhone devices with defective parts like those with bad camera issues but appropriate action was taken to resolve them. If you have concrete data to show that a lot of iPhone 6 and iPhone 6 Plus devices have exactly the same issue due to a defective chip, let Apple about them. We are NOT Apple’s technical or customer service team.

Thirdly, if the flickering and freezing up issues are caused by a bad chip, it should have happened sooner. If your phone had been working fine for over a year though, telling us that it’s Apple’s fault that your phone is now acting up is ridiculous. We understand that you expect your phone to last longer than over a year and a half but your device does not exist in a vacuum; you’re using it day in and day out. Aside the from the normal wear and tear, there are other reasons why it may be freezing up, or the screen flickering. Causes can include possible content/app bug, unknown software glitch, or physical damage. We don’t know the full history of your device so we can’t say exactly what’s the reason for these symptoms. (Make sure to always include history of your device when contacting any technical support team for whatever issue). The only suggestion we can give to you is to see if these issues can be fixed in your end or not by doing a factory reset. Here’s how:

  1. Create a backup of your important files.
  2. Sign out of your iCloud account (if applicable).
  3. Go to Settings.
  4. Tap General.
  5. Tap Reset.
  6. Tap Erase All Content and Settings.

Lastly, we would like to emphasize the fact that there’s not much that Apple users can do in this situation. The way we look at it, your phone has a hardware issue. Any time a smartphone screen suddenly starts to flicker on its own, it’s almost always due to hardware error. If you accidentally dropped or exposed your phone to water/heat before, don’t expect to fix this problem by tweaking some settings. 95% of the time, screen malfunction issue is caused by physical damage so changing some settings won’t help. Unless you have the expertise and tools to troubleshoot the hardware and diagnose any hardware issue, let a professional handle the task. Hardware troubleshooting requires physically checking the device. It’s one of the reasons why we don’t support hardware problems. If factory reset won’t fix the problems at all, repair or replacement is your only option.

Problem 2: iPhone 6 screen vibrates near Home button

Screen vibrates on the very bottom near Home button. It then moves up the screen. It is still useable and I can still see the screen; it’s just very annoying. It seems to happen with lower power and not plugged in. I replaced the screen about a month ago; it was cracked. It worked perfectly after until a week ago. I think also the battery is not as good as it used to be. I read that a temporary fix to the touch disease is to turn brightness down. That stops the vibrating temporarily. I have also stopped it by turning brightness up and then back down. Having my screen dimmer seems to lessen the problem. — Ae_electric1

Solution: Hi Ae_electric1. We’ve heard of a few anecdotes about similar issues in the past but there seemed to be no common pattern in those cases. We’re almost certain though that they are not caused by a software glitch since they only occurred after the devices underwent some form of repair.

Replace the battery and/or the screen

For your case, it may be worth checking if it has something to do with the battery. Sometimes, a battery malfunction can send incorrect inputs to the operating system, which may in turn result to erratic behavior of some features or functions. In the same vein, replacing the current screen may fix the issue as well, especially if the one you’re using has been damaged for some reason.

Do a full restore

Just to be sure, consider doing a full restore before taking the phone apart so you can observe how the device works afterwards. Be sure to restore your phone as a new device (not from backup) and observe how it works for some time before you install any app.

To do a full restore, follow these steps:

  1. Create a backup of your files. You can do that in a number of ways but the fastest and most effective way is by using iTunes in your PC or Mac. If you don’t want to create a backup at all, you can simply erase everything on the phone by following the steps in this link.
  2. Connect your iPhone to your computer with the cable that came with your phone.
  3. We assume you remember your phone’s passcode so simply enter it when you’re prompted for it.
  4. Select your iPhone once iTunes asks you for the specific device.
  5. Once you’re in the Summary panel or screen, select the option that will restore your device (Restore).
  6. Confirm by clicking on Restore button.
  7. Wait for a few moments while iTunes restores your device to its factory settings. It may also take some time if iTunes will need to install an updated operating system version.
  8. After this factory reset, all software settings should be restored to their defaults.

Problem 3: iPhone 6 becomes unresponsive after accidental drop

So I dropped my phone a few days ago. There was no crack but the screen doesn’t respond to touch anymore very well. I have to restart the phone (pressing power and home button simultaneously) and only then will the touch screen be responsive, however it will only be responsive for about 5 minutes of use, then it will work on and off. Is it a hardware or connection issue? — Safia G.

Solution: Hi Safia. If this problem started to occur only after you accidentally dropped the device, this must be a hardware issue. The display assembly of your iPhone 6 has three major components — LCD/monitor, digitizer, and flex cable. The LCD is the part that shows you images in the screen. In order to get input from you, the operating system needs a part that can take your finger touches and this is the job of the digitizer. Then, those analog finger touches are transmitted by the flex cable to the motherboard so they can be processed by operating system. If your phone appears to stop detecting your touches by becoming unresponsive, it’s either due to a bad digitizer on top of the LCD, or by another unknown hardware malfunction. To fix any of them, you should send the phone in so a technician can check the hardware.
