iPhone 7 is slow and unresponsive after screen replacement, other screen issues

Hello iPhone fans! Today we cover screen problems on #iPhone7 devices. In almost all instances, broken screens can result phone repair or replacement. This is due to the fact that a broken hardware can’t be fixed by tweaking any software setting. If you find yourself with a mangled or physically broken screen, this article won’t give you a solution to fix it. What you need is a screen replacement.

Sure there are many websites that provide do-it-yourself guides on how to replace a screen but keep in mind that screen replacement, though it looks simple, can lead to more problems if not done properly. Novice users tend to create more problems than fix existing ones when doing DIY repairs for the first time so be careful. If you are absolutely positive that only the screen is broken, go ahead with repair. If there are more problems other than the screen, you’ll most likely need to perform in-depth hardware diagnostics, which may require more advanced tools and expertise. In this case, we recommend that you tap the help of a professional instead of doing the repair yourself.

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 7 is slow and unresponsive after screen replacement

I replaced the screen on my iPhone 7 Plus. After doing so, the phone is extremely slow and unresponsive. Sometimes a click on the touchscreen needs more than 10 seconds to register and booting the phone takes somewhere around five minutes.

Also, the home button does not work any more. Finally, the back camera which obviously has not been touched besides by removing the battery connector to make sure the phone has no power, keeps jumping around while filming. Meaning that the video looks like I was shaking the phone while in reality it was perfectly still. — Falk Thieme

Solution: Hi Falk. We know nothing about the events that prompted you to replace the screen so probably you have to look into that. It’s possible that a broken screen is only one of the external signs that the hardware is broken. For instance, if your iPhone was dropped, which lead to a broken screen, it’s possible that the blunt force also damaged other components such as Home buttons, camera, or the motherboard in general. In other words, the problems your iPhone 7 are showing are probably the direct result of a general hardware failure, which can only be permanently fixed by replacing the motherboard and other affected components.

If you don’t know how to diagnose each affected component, we suggest that you let a professional do it for you. Our blog does not provide hardware troubleshooting and diagnostic assistance so letting Apple or an independent service repair your device is our only suggestion.

Problem 2: How to recover photos from iPhone 7 with broken screen

I dropped my iPhone and of course the screen broke, which isn’t the biggest issue here. My issue is that the display doesn’t work. It comes up as solid white and just like one green and red line in the middle of the screen. I already bought another phone. My main concern is if I’m able to repair it because really I just want my photos (I learned my lesson… always use iCloud) and I don’t care how much it costs to repair. I just want to know if it’s possible. I can send you a photo through my email if that’ll help?? — Kylie

Solution: Hi Kylie. The only way to recover photos from a phone with a broken screen (hopefully only the screen is not working at this time) is to replace the bad part. That’s because you need a working touchscreen in order to unlock the device and tell the operating system to allow the movement of files. If you can’t unlock the screen and confirm the connection with, say, a computer, those files remain inaccessible.

If you’re lucky and the damage is only isolated to the screen, a screen replacement should easily solve your issue. And that’s a good thing since you’re willing to pay for the repair. We suggest that you bring the device to an independent service center so you can tell them not to erase the memory during repair. Apple service center will usually wipe the memory for security reasons.

If you think you can manage a DIY (do-it-yourself) screen replacement, there are a lot of websites that can provide the necessary steps and even the kits you’ll need. Just use Google to search for them.

Problem 3: iPhone 7 touchscreen stopped working, can’t enter passcode due to broken touchscreen

Good Morning. I recently purchased an iPhone 7 from a friend, but I’ve yet to use it. The touchscreen was working fine until an hour or so. It froze and I tried to manually reset it and it didn’t work after that. I repeatedly reset it and still the same issue. I cannot get past the passcode section due to the touchscreen, so i am unable to try to factory reset via phone or computer. I took it to get a new screen and he showed me the previous screen had melted prior onto the phone so i figured maybe that was the reason, after the new screen once again in the next hour it stopped working. He has asked me if it was a motherboard issue, but I disagreed because I already went to an Apple store and had a diagnostics done to my phone and everything was working perfect, I only needed a screen replacement, but i did that also and still no improvement. — Akwasi Appiah

Solution: Hi Akwasi. Whenever something melts in the system, that almost always suggests there’s excessive heat being generated somewhere. An iPhone 7 can only tolerate a certain level of heat. Since the original screen had been damaged by heat before and the same exact symptom is happening on the replacement screen, it’s highly possible that the main cause has remained unaddressed. As long as the cause of high heat level is not fixed, screen replacement will fail after some time.

Overheating can sometimes be caused by a shorted component or a poorly connected part so we suggest that you let a professional check the hardware. Be sure to mention all symptoms including the overheating problem. We can’t tell you where this heat come from but a good technician who can physically check the motherboard should.

Problem 4: iPhone 7 logs out all accounts, won’t allow user to log back in, Bluetooth not working after screen malfunction

I recently fixed my iPhone 7 screen and it’s been about a week but now my iPhone is really messing up. It logged me out of all my accounts and for some reason I can’t log back in. When I try, it freezes then sends me home. The Bluetooth is unavailable. When I try to connect to my WiFi it says something went wrong, it constantly asks for my Apple ID password and lags a lot.

Also when I’m not getting good service it seems to reboot after unlocking it. It deleted all of my messages as well. I don’t know if it’s because of the screen replacement or something wrong with the software. Please help. — Eloy Gonzalez

Solution: Hi Eloy. We’ve performed screen replacements on a few iPhone 7 devices ourselves and so far, we haven’t encountered any of the problems you mentioned. We also don’t see the logic of a bad screen as the cause why you’re logged out of all your accounts, or Bluetooth suddenly stopping to work. There must be another reason for these issues.

Since iOS troubleshooting is very limited, all you can do right now is to try to restore the device. We suggest that you boot the phone to DFU mode and do the restore from there. Here’s how:

  1. In your computer, close all active apps.
  2. Open iTunes.
  3. Turn off your iPhone. If you can’t turn it off normally, let the battery drain to 0% so the phone powers down on its own. Charge the phone for at least an hour without attempting to turn it on.
  4. Connect your iPhone to the computer via USB cable.
  5. Press and hold the Power button for at least 3 seconds.
  6. Press and hold the Volume Down button on the left side of the iPhone while continuing to hold the Power button. Be sure to hold both Power and Volume Down keys for 10 seconds. If Apple logo appears at this time, repeat steps 5 and 6. Apple logo should not show at all.
  7. Continue to hold Volume Down key for another 5 seconds. If the Plug into iTunes screen is displayed, repeat steps 5-7. Plug into iTunes screen should not show up.
  8. You’ll know that your phone is in DFU mode if the screen remains black. Your computer should then tell you that iTunes has detected an iPhone.
  9. Follow the on-screen steps in your computer to do a full recovery.

Remember, factory reset or restore via DFU mode is only effective against software problems. If the issues continue even after you’ve restored the device, that’s a clear indication that the cause must be deep within the hardware. You should consider sending it to Apple so it can be fixed by a trained personnel.
