Problem 1: iPhone 6 screen not working properly

My iPhone 6 has been periodically having screen problems. What happens is that the screen goes completely dark OR just dark gray (I can faintly see the screen data but the touchscreen does not respond). This has been happening off and on for six months. It is usually just off for minutes to a couple hours. During the off time I can receive a call, but I cannot answer it or use my phone in any fashion. I have done the reset, but not a reload to factory settings. Somehow I don’t feel it’s a software problem, but I could be wrong. Seems to me that some contact is temporarily lost as today I decided to squeeze the top and bottom of the screen when it happened and the display came up and has worked perfectly since. Any clues? Thanks in advance for your assistance! — Judy

Solution: Hi Judy. In majority of screen-related cases, especially the one you’re having, bad hardware is to blame. So, you may be right to think that it’s not a software issue at all. Was your phone dropped before? Although most phones can survive the physical impact of a bad drop, some devices may not be so lucky. If your phone’s screen was damaged by a fall before, that’s probably the reason why it seems to only show full screen colors when you apply pressure on it. To ensure that it’s not a software issue at all, we want you to reset your phone to factory reset settings first. If that won’t change anything, consider sending the phone in so a technician can check the condition of the screen.

For the benefit of iOS users, below are the steps on how to factory reset your iPhone 6 device:

  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 2: iPhone 6 keeps restarting, won’t install update

Hi. About two weeks ago I was at work and my phone died. I got home i charge it, and the Apple sign pops up. Then it goes black but is still kind of lit up and then shuts off and pretty much resets itself as if it was in an infinite restart mode or so. It was doing this for a couple days turning off and on and whatever.

Then, after letting it be dead for a week, I went to show my friend what it was doing. The sign popped up again but then took me to my screen, and it wasn’t on for about an hour. and then I backed my phone up and deleted some apps and tried to see if that might’ve been a problem. And then I don’t know why but I figured I should update it to the 10.3.1 and while it was doing good for a minute, a littleness spinning thing came up at the end, the bottom ended up restarting again and been off and on to my screen.

I took my SIM card out tried the hard restart and I’m not sure what Apples able to do or how much to charge. Could it be my SIM? Or a software problem?? Battery?? — Taylor

Solution: Hi Taylor. There’s not much information about the history of your phone that we can use so it’s hard to tell what may be the cause of your problem. The logical thing to do here is to try all available software solutions first. If nothing works after that, you can assume that it may be the battery or any unknown hardware issue with the motherboard.

Firstly, you want to ensure that your phone runs the latest software version, which is iOS 10.3.1 (as of this writing). If you’ve already tried that but the update did not finish properly, there must be more serious cause for the problem.

This can’t be a SIM card issue. You can confirm that by simply removing the SIM card and observing the phone.

The best thing that you can do right now is to restore all settings to factory defaults. Refer to the steps above. If nothing will change after that, you should contact Apple so the hardware can be checked, or your carrier so the unit can be replaced.

Problem 3: iPhone 6 keeps rebooting and won’t restore to factory settings via iTunes

My iPhone 6 was working fine, then 5 minutes later it was just rebooting over and over. I brought it to Apple and they said there was something wrong with the circuitry, they couldn’t restore it. But that doesn’t make sense because it literally was working only moments earlier and nothing happened to cause such a situation. So right now it is reset, and when I plug the iPhone 6 into iTunes to restore it, it says “There was a problem downloading the software. the requested resource was not found.”

I have the most up-to-date version of iTunes. My computer works fine besides, and Apple couldn’t restore the device either. But a circuitry just doesn’t make sense. Where do i go from here? Delete the Cydia Substrate? — Richard

Solution: Hi Richard. If the phone won’t allow you to restore itself fully (factory reset) like the one detailed above, simply erase everything by following the steps below:

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

If that won’t work either, send the phone in.

Problem 4: iPhone 6 plus sound settings keeps reverting to default, duplicate contacts keep showing up

I have been having an issue with my iPhone 6 plus, where if I power it down or do hard reset, when it powers on the text and ring tones will revert back to default. I can go in to sound settings and see my purchased tones, but when I check them to use them or assign them to a contact they do not work, even though they show as checked. The only solution I have found that works randomly is to power the device on and off until it is fixed, sometimes I do this 3 times, but other times it takes 15-20 attempts. Another way that will sometimes, but not always fix it is to reset the network settings. Again this is not 100% successful.

I find myself avoiding powering off or resetting my phone in fear of having to deal with this. It is so frustrating I am contemplating creating a new Apple ID.  Do you think this would fix the problem?  Is it a bug embedded in my current Apple ID?

Another issue I have is that I now have double or triplicate contacts because my phone has synced with my contacts, iCloud, and several other emails that all created duplicates. This is also very frustrating, and another reason I am considering getting a new Apple ID. Please advise. Thanks. — Brian

Solution: Hi Brian. If by hard reset you mean holding the Wake and Home buttons together for at least 10 seconds, then it’s probably not enough to fix the issue. We don’t know the current state of your software so we can’t say for sure if it’s a software issue or a sync issue with your Apple account. We suggest that you try to restore your phone to factory settings instead of getting a new Apple ID first. Please see steps above on how to do a full factory restore.

For your second issue, it’s most probably a sync problem. We can’t say with enough certainty if both the main issue is tied to this one but if a full restore won’t fix the second issue as well, you might want to switch to a new Apple account.

We don’t think this is a device problem as we haven’t encountered both issues in the same device before so a full restore must fix them.

Problem 5: iPhone 6 plus screen showing multiple colors and won’t work

Hi. I have iPhone 6 Plus, approximately 2 years old. Had no issues until last two weeks. Screen blank and reset worked using two button hold. Today, I put the phone on charge, all okay. Reached 20% then I unplugged as I had to go out. Phone display upon waking phone up next use the siren was lit but looked as if taken a photo of multicolored glitter. Blue and multicolutred tiny dots. Cannot do anything, reset returns me to this screen again, it stays lit until closes time out as normal. Put on charge and phone bleeps accordingly. Tried to call the phone, it rings correctly and screen lights up but stays this multicoloured dots all over, no visible display etc just this screen. Has not been dropped or damaged, warm weather but not left in sun nor is there any damage to the screen glass etc I have taken a shot of the screen onto my iPad. Confused…what can I do please? — Sally

Solution: Hi Sally. Screen discoloration or, in your case, multi-coloration, is usually caused by a defective screen. We know that iPhone 6 screens are of good quality as two of our iPhone 6s are still working great at this time so yours might be a fluke. If you’ll be unable to perform a Full Restore on the device right now, you should contact Samsung or any relevant party for assistance. The phone most likely need a screen overhaul so if it’s out of warranty, you’re out of luck. You’ll have to spend on the repair.

Problem 6: iPhone 6 screen is black and won’t turn on

Hello. I have an iPhone 6 which I have had for around 4/5 months. I had another iPhone 6 for almost a year however I dropped it down the loo (oops) and had Apple replace it with said phone, which is now giving me hell.

My problems started about 3/4 weeks ago when my screen started to show lines and become unresponsive and flash. I reported the issue to O2 (my carrier) and they offered to fix it. However, with a busy lifestyle, I needed a quick fix as I can’t be without my phone due to the nature of my work.

I took the phone to a phone repair shop and they fixed the initial problem of the screen going liney and flashing. However, the screen is now going black and flashing on and off completely. I know the phone is still working because I can hear my notifications going off and my music will continue to play when the screen goes black, so it is not an issue with the phone itself besides the screen.

I took the phone back to the repair shop the same day and told them about it and they claimed it might be a loose connection which I agreed. So then I let them have another go at fixing it and thought it was fine but when I got home I had the same issue.

So, today I took it back again and they tried to fix it again, and assured me it was fixed, but I am home once more and no joy. SO now I am trying to update my iOS. i’ve restored the phone to factory settings, not sure what else I can do. But I’m definitely going back to that shop for my money back. Please please help me out here, I’m at my wits end. — Kara

Solution: Hi Kara. Your issue is clearly not something that can be fixed by tweaking some settings, or by doing a software solution. It’s a more serious problem because it obviously involves a bad screen. And that’s something that we cannot help you with too. We’re here to help users with software problems. Unless you have some basic electronics knowledge and tools to replace the screen, we won’t recommend that you attempt a do-it-repair.

We know it’s not ideal for you to have no phone for days but replacement is really the best thing that you can do right now. Contact your carrier and ask for a phone replacement.

Problem 7: iPhone 6 screen stays black, screen not working

Hi kind souls. At wits end with no idea what is wrong with my iPhone. Anyone knows any possible reasons as to why my phone is acting this way? I wish to find out the root cause of it and fix it if possible since I recently just replaced the screen. Otherwise as a last resort to back the data in my phone up and just get a new iPhone.

So here goes…. Basically, phone was working fine before SHTF. Phone hanged, totally not responding. Only responded to screen locks, tried unlocking the screen and got the picture below instead (edited the photo to show my issue)   View Original Image metadata Copy to my images Thereafter, did a hard reset. Reset went fine, but phone hanged again. Then it decided to die, and now it shows a black screen only. Pretty sure there’s still battery in it. Responds to iTunes, but my phone is locked with a passcode so basically I can’t back it up. Left it for a few days for the battery to drain.. Update – Just plugged in my charger, it showed the empty battery icon on the screen. waiting for it to charge up, hopefully it boots up so I can back it up. Basically I got it to work, and left it to charge. Came back to the same problem again… — Teozheming1996

Solution: Hi Teozheming1996. If your phone’s screen is unresponsive, there’s nothing much that you can about it. All software troubleshooting for this device requires a good working screen. There’s no way to bypass the passcode screen so another device can access the phone’s memory and back files up. The screen is the only gateway to your device and without it, you have an expensive paperweight. Have the screen replaced to fix the issue.

Problem 8: iPhone 6 can’t download updates or install apps, won’t connect to wifi

Hi. My apps won’t download or update. Whenever I download them from the App store they begin to download and then say they are unable to download at this time. No apps have updated either even though I have automatic updates on. My phone never connects to wifi so I can no longer update the ios and has massive connectivity problems, often saying no service when other people on the same network have 2 or 3 bars. My banner notifications on my lockscreen have also turned pink since this happened, although my clock and the badge icons for each app are white. Phone has also been lagging for the past few days. I’m not sure if these are related problems. — Katie

Solution: Hi Katie. Since you are experiencing multiple problems at once, we suggest that you restore all settings to factory defaults. Please see the steps we detail above.

Once, you’ve reset the device, you can then try to download your apps again. Your phone should be able to connect to wifi at this time so try to check if it can.

If there’s no wifi network available, make sure that your mobile data is working.

Problem 9: iPhone 6 won’t make a sound when disconnected from wifi

Some months ago, my iPhone 6 Plus developed sound problems. Whenever I leave the house (i.e. my wifi) the app sounds stop working. Can’t hear voice notes, notifications or listen to audio books. As soon as I come home, the sound will work again. Whenever this happens, a reboot will fix the issue. The problem seems to be related to the type of connection – going from wifi to 4G causes the speakers/app sounds to stop working. When I leave the house, I am usually in the car where the phone would connect to the car speakers via Bluetooth… Could this have something to do with it? — Tessa

Solution: Hi Tessa. The following are things that you should try in fixing this issue:

  1. Ensure that the Ring/Silent switch does not show orange indicator. If you can see orange on the switch, your phone is set to silent mode.
  2. Ensure that the audio port is free. There should be no debris or dust visible. If there is, it might cause a problem like the one you’re experiencing.
  3. Turn off the Bluetooth service of your phone. Yes, if your phone is connected to a Bluetooth service, it might prevent your device from making sound notifications. Try to turn Bluetooth off when leaving your house and observe the phone.
  4. Get the latest iOS software update.
  5. Backup your phone then restore your phone to its original factory condition and set it up as a new device.
  6. If the issue persists you need to contact Apple Support.

Problem 10: iPhone 6 won’t connect automatically to some wifi networks

Hello. Thanks for your help ! My iPhone 6 get trouble with wifi connection. First, it doesn’t connect automatically to some networks. Sometimes, i have to activate and deactivate a few times the 3G to make the wifi launching. Sometimes, it doesn’t work.

When i go to the wifi settings, even if the wifi is working the wifi and the hotspot asking are deactivated and when i go there 2 times in row the wifi is off (even if i still have connection …). It’s really annoying because it make me using a lot of data. The curious thing is that this was happening on my old phone too and i restore the new one with my back up so it should maybe be a setting. If you have some idea would be nice Thanks again best regards. — Nico

Solution: Hi Nico. There’s no setting in an iPhone that can result to the issue you’re having right now. It’s most probably caused by a buggy app so we recommend that you back all your important files (photos, videos, etc) up and wipe the phone clean. Use the following steps to clean up the phone:

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

Once you’ve done all the steps, observe your phone again and see if wifi will work normally. Make sure not to install anything during this time. If wifi works, install apps one by one and be sure to test wifi functionality after every installation. This is the only way to know which of the apps is problematic.

  1. My daughters IPhone 6 won’t get service it just says searching. Verizon said I need to do system update but when we went to it said it couldn’t connect to wifi. We could connect safari and the app store. This phone is in perfect condition. This problem comes and goes.
