iPhone 6 Plus randomly showing “This cable or device is not certified and may not work reliably with iPhone” error

Problem: I keep getting the following message, all the time, especially when I have nothing plugged into the device  “This cable or device is not certified and may not work reliably with iPhone”.  It is driving me nuts!! Just randomly appears, even if the device is sitting on my desk. Help! Thanks! — Susan

Solution: Hi Susan. The error “This cable or device is not certified and may not work reliably with iPhone” normally shows up if your device is connected to an accessory (usually to a charger) that doesn’t meet Apple’s requirements. In this case, you can rectify the issue by using first party accessories or third-party ones certified by Apple.

However, if the phone keeps on displaying the error even when it’s not connected to an accessory like a charger, there may be an on-going problem with the firmware and you may need to erase all contents and settings in your device. Keep in mind that this operation will delete everything in your phone so make sure to create a backup copy of all your files, photos, videos, contacts, etc before proceeding. Here’s how:

  • Go to Settings.
  • Scroll down to Reset.
  • Select Erase All Content and Settings (factory reset).

Now that you have restored your iPhone to its original state, give it some time to do its thing and observe it. If the error will not return, that means that you have successfully eliminated it but if it’s the opposite, please call Apple support or your service provider to ask for replacement phone.

iPhone 6 Plus unable to connect to App Store or iTunes via Wi-Fi

Problem: Dear iKream. I recently stumbled upon your website while at work, and I’ve noticed you provide great troubleshooting and advice. I’ve been suffering quite an issue with my new purchase and I really hope you have a solution to my problem! 🙂

I’ve just bought a 64GB iPhone 6 Plus here in Beirut, Lebanon. But so far I have been unable to connect to either the App Store or iTunes through my Wi-Fi connection to download any apps. Whenever I open the App Store, all I get is just the names of the apps appearing and it takes forever for all the photos and screenshots to actually load (I have a 1Mbps internet connection, which is not a lot, I know, but I should think I would at least be able to download something, even if slow). After I’ve chosen an app and clicked on ‘Get’ and then ‘Install’, all I get is that circular search movement icon, without any loading, and then it stops and goes back to ‘Get’.

Also kindly note, that everything works fine on cellular data (3G) and I’ve been successful in downloading a few apps with that. And also, it is worth mentioning that even on Wi-Fi I do manage to download some apps only very early in the morning (5-6AM), but later on throughout the day, it is practically impossible to download anything (even when I’ve disconnected every other device in the house, the apps do not even reach the download stage, only that circular search process).

I have tried everything from factory resetting to changing the date and time to automatically set, to turning off location, to restarting my Wi-Fi connection, and nothing seems to fix the issue. Could there be some sort of defect in my device, or is this related to settings or maybe, possibly something at my ISP’s end!?

Please help because this is driving me insane as the main reason I got the Plus is to download apps!

Looking forward to your reply and many thanks in advance. — Rami

Solution: Hi Rami. Do you have another Apple device (iPod,iPad,Mac) that can connect to App Store or iTunes via Wi-Fi without any problems? You need to try this out first to rule out a possible issue on your ISP’s end. If another device can access any of these two sites when linked to your home Wi-Fi, that’s an indicator that the problem is most likely in your iPhone only.

We know from experience that logging out from one’s Apple account then logging back in sometimes work. If you haven’t tried it, just go to Settings>iTunes and App Store. Once you are in this section, select your Apple ID and tap View Apple ID so you can enter your password. Afterwards, try to connect to App Store or iTunes.

Alternatively, you can also try to accept the new Terms and Conditions under Settings>iTunes and App Store so you can connect.

If nothing works, please ask assistance from Apple support as this might be an account-related restriction.

iPhone 6 Plus camera unable to focus

Problem: Dear Mailbag. Hello I’m Delvalee. My iPhone 6 plus is having problems with the back camera. It doesn’t focus even when I hold it steady and in good lighting it doesn’t seem to focus. Could you please help me with this? Yours sincerely. — Delvalee

Problem: Hey Kream. After one week of using my iPhone 6 Plus, I had  a focusing problems on my camera. I tried everything possible but didn’t work. Do you have anything helpful to do? I will be so glad. — Anastasiya

Problem: Good afternoon, I found your article to be very informative on Zite. I was just wondering if you knew of any easy fixes for the iPhone 6 camera. My camera takes very crummy pictures compared to my girlfriends camera. Looks a little distorted sometimes to light. — Richard

Problem: Hi. My issue with the iPhone 6 plus is that my rear camera works fine until I zoom and then it will not focus at all no matter how still I stand. Blurry pictures is all I get when I zoom. Thanks. — Angie

Problem: Hello Sir/Madam. I, Tarun Patel, am writing an email regarding camera problems with my iPhone 6 plus. Past a day or two, I tried to use my camera, but the focus won’t work. I tried from the camera directly, snap chat and other application but it just wouldn’t focus. And so haven’t been able to get good pictures. I won’t deny it hasn’t fallen. It has, once or twice, but that was like a few weeks back. Any help towards this would be highly appreciated. Thank you! — Tarun

Solution: Hi Guys. Have you tried checking the lens at the back for possible smudges that may distort or interfere with the light going into the camera? Kindly use a microfiber cloth or any clean soft cloth to wipe the lens.

The next potential solution is by force closing the camera app. Here’s how to do it:

  • Press the Home button two times quickly. You’ll see small previews of your recently used apps.
  • Swipe left to find the app you want to close.
  • Swipe up on the app’s preview to close it.

If the problem remains, resetting the phone is the next procedure. To do it, simply press and hold the Sleep/Wake and Home keys for at least 10 seconds. This will restart the phone.

Sometimes, a metallic case or magnetic lens may interfere with the camera function, particularly with the optical image stabilization feature. If you have any of these, try to remove it and to use the camera again.

Richard, please try these solutions above. If they are of no help, kindly restore the phone to its factory defaults to ensure that the phone runs a clean firmware.

How to unlock an iPhone 6 Plus if a user forgets the passcode

Problem: Dear. I am Bharatth Bhansaali from Ahmedabad, India and I own a iPhone 6 plus. I had set a passcode and to my bad luck I forget it and my iPhone got disabled. Now on the screen it is showing connect to iTunes. My problem is that I had photos in it which I want back up and previously I don’t have any back up. Can you find me a way to get it started without losing any data? I need a back up of my files. Please help me. — Bharatth

Solution: Hi Bharatth. If you did not sync your phone to iTunes before, which means your photos are only stored in the local storage device in your phone and NOT somewhere else like in a computer or Apple cloud, there’s just no way for us to recover those files. Because the only solution to bypass the passcode screen is by restoring the iPhone to its factory default, the said operation will also delete whatever data are kept in your phone.

iPhone 6 Plus call delay problem | intermittent call issues on iPhone 6 Plus

Problem: Hi. I am having intermittent problems when answering and making calls. When swiping the screen to answer a call, it

looks like you have answered but there can sometimes be a delay of between 2-5 seconds before the call connects. Also when making a call sometimes the other person cannot hear anything so they put the phone down but when you ring back everything is okay.

Problem: Hi. Every now and then I am told by people that they’ve been calling my phone and it has a funny ring and busy signal. Meanwhile I will at times have my phone right in front of me and it doesn’t ring nor do I receive notice of a missed call. I’ve rebooted it multiple times. Had Sprint trouble shoot 10+ times.., reset it to factory settings., added updates all to no avail. I am still having trouble receiving calls. Help. — Meka

Solution: This issue may be network-specific. Have you consulted your carrier if there are any problems in your area? This may be indicated by “No Service or Searching” error in your device. Assuming however that there’s no coverage or service problems in your location, you can do these potential solutions:

  • Restart the phone.
  • Check if your phone runs the latest carrier settings. Carrier settings updates are sets of files from your service provider requiered in order for your iPhone to properly connect to the network. To check if the phone is up-to-date, go to
     Settings>General>About. If an update is available, a prompt will appear to inform you accordingly.
  • Remove and re-insert the SIM card. Sometimes, this simple step works wonders. Make sure to turn off the phone before doing so.
  • Call your carrier. At this stage, you want to ensure that there are no local outages that they may missed to tell you, or if your iPhone is set up correctly to work on their network.
  • Verify if the network settings are correct. If you have no handy information to verify the details of your network, doing a network reset by going to Settings>General>Reset>Reset Network Settings may help resolve the problem.
  • Try switching to another network band. Go to Settings>Cellular and turn off Enable LTE, 4G, or 3G and switch to whatever available network band you have.
  • Request for a replacement. If nothing else work, consider having your device replaced.

How to fix iPhone 6 Plus not charging issue

Problem: Hi. I was just wondering whether you’d have any advice for a problem I just had with my iPhone 6 Plus. My battery drained, and I plugged in the charger but it didn’t seem to charge. I connected it to my laptop and it showed the Apple logo, but then died again and then showed the logo and died again and basically keeps doing this until I disconnect it. I haven’t backed it up on my laptop and i don’t want to lose my data. Do you think the best solution is to replace my battery? — Sarah

Solution: Hi Sarah. A problem like the one you have normally happens if the battery is really low so these are the things that you can try:

  • Turn off the phone completely.
  • Charge your iPhone for at least 20 minutes before attempting to power it back on.
  • Check the charging port on the phone for any sign of debris or foreign object.
  • Try using a different USB cable if you are charging through a computer or another iPhone charger.

If nothing works, consider having the battery or the phone replaced. Remember that replacing the battery of your device may void the manufacturer warranty.

iPhone 6 Plus opens apps, uses touchscreen on its own when personal hotspot feature is active

Problem: Help! I just went back to iPhone after a one phone hiatus with a Samsung S4, the boss got me the Samsung phone for a project and then gave it to me full time. So I had to turn my 1-month old 5S over to my 13 year old daughter.

Anyway, the reason I’m contacting you is I seen some of your troubleshooting steps and I wanted to see if you have seen anything like I’m seeing. If I need to get a new physical device, then I need to do that soon, rather than waiting for a while. My thoughts is it is software, but let’s see what you have to say.

This issue only seems to occur when I have the iPhone with the personal hotspot active. I of course have the phone charging when this occurs, as I always try to have it charging when I’m using the hotspot. If I’m using my phone with the hotspot going in the background, the phone seems to make button presses on its own. Like I will be flipping through apps or pages, then all of a sudden it selects something off a page I’m on. This occurs pretty frequently when I have this active. I have tried re-starting my phone with no success. Please let me know your thoughts on this. Thanks. — Brian

Solution: Hi Brian. This is the first time we’ve heard this problem in an iPhone 6 so this must be a unique case. There might be a unique bug being triggered by the phone’s hotspot function in your phone so the best thing that you can do is to do a factory reset (that’s Erase All Content and Settings under Settings>Reset). This ensures that your phone runs a clean iOS version as well. Hopefully, this process will also eliminate the bug.

If that won’t work, consider contacting Apple support so you’ll know what they have to say about the matter.

iPhone 6 Plus reboots on its own after setting sleep mode, Bluetooth and Wi-Fi not working

Problem: Hi. My daughter won an iPhone 6 Plus last week on a cruise. That’s great. She already has an iPhone and has given this to me.   The phone does not seem to work properly, and I don’t think we can have  the Mac store fix it since she won it and there is no warranty? Here’s what’s going on:

  • When we set the phone to go into sleep mode after say a minute, within a minute or two after that the phone just shuts off.  We can re-start it, but obviously that creates issues for incoming phone calls and messages.
  • When we go to turn on the Wi-Fi in Settings it is grey, and will not allow us to turn it on.
  • When I turn on Bluetooth I just get a spinning dial, and nothing more.

Any suggestions would be appreciated. — Mike

Solution: Hi Mike. It seems pretty odd for a new iPhone 6 Plus to have these problems at such an early stage. We suggest that you do a complete factory reset (steps provided above) so you can be sure that there’s no firmware issue behind all these. If the problems remain after restoring the phone to defaults, that’s an indicator that you may have a bad hardware.

iPhone 6 Plus touchscreen issue

Problem: Every time I plug in my iPhone 6 plus it start to wig out. It freezes up to where I can’t touch it and then when you do touch it it clicks on a whole different area. Or it will start pulling up different apps and touches things by itself. I don’t know if I explained this enough but if not please contact me and let me know. Thanks! — Brittney

Solution: Hi Brittney. Looks like you have an issue with the phone’s touchscreen. Just like our suggestion for Mike above, please do a full factory reset first to rule out a possible firmware side of the problem then consider having the phone checked by a certified Apple technician if the problem persist.

iPhone 6 Plus skips music when connected to Mercedes E 350 Bluetooth

Good Evening!

Thank you so much for providing this forum and your generosity with expert advice to individual questions/problems/issues!!

I have had an (several) issue(s) with Bluetooth® music in my new Mercedes … This is my 3rd replacement phone, so it’s not the phone as the car dealer stated. The vehicle is new and has been diagnostically tested twice with no fails. I am still having the same issue.

  • With music from iTunes it arbitrarily skips  bits of the song for no apparent reason, and it drives me nuts – as I said I have had the vehicle checked twice, the phone replaced 3 times, deleted the iPhone from the Bluetooth® devices in the vehicle’s system on several occasions and reconnected the device as new – same problems with the skipping.
  • When  Bluetooth® is engaged, Siri through the vehicle is like talking to a foreign computer telecenter for tech support – the results are uproariously funny, if you were so dang mad nothing you have just said was even not the slightest bit close to what finds it was in a text.
  • When Bluetooth® is engaged and I utilize the vehicle’s internal system, folks on the other end say it sounds like I am driving with the windows rolled down??

I am sure some of this could be tinkered with by carefully reviewing the online Mercedes E 350 manual. Maybe/maybe not…as I have heard the latest and greatest BIOS has many issues, and people are just living with until l Apple releases a fix.

Just wanted to get your thoughts!

You are greatly appreciated!

Sincerely. — Cory

Solution: Hi Cory. It’s a known fact that Apple’s Bluetooth system has compatibility issues with many other car models and brands. The last time we combed through Apple’s discussion forums and other third party forums, there are hundreds, if not thousands, of car owners complaining about all sorts of Bluetooth issues with this popular device.

The problem basically stems from Apple’s closed system, making it harder for car makers and developers to fine tune their own system. Although there’s no official admission from Apple, there clearly exists a huge problem with how Bluetooth on their iPhone 6 and 6 Plus works with other systems. The problem is further compounded by the most recent iOS update, which makes your phone’s Bluetooth a step more advanced compared to your car’s Bluetooth which was probably designed a few years back. While we are not quite sure yet, it appears that Apple’s Bluetooth system is not backwards compatible resulting  to a wide range of issues for car owners.

We suggest you let Apple know about the issue but we doubt if there’s a meaningful resolution to it from their side at this time.

You may also consider getting a compatible infotainment system for your car but that implies an unnecessary investment obviously.
