How to detect iphone

Locate and view your connected device on your computer

After you connect your iPhone, iPad, or iPod to your computer, you can view it and access its settings in the Finder or iTunes.

View your device in the Finder

Starting with macOS Catalina, your devices appear in the sidebar of the Finder. Click the device to select it.

View your device in iTunes

Make sure that you have the latest version of iTunes. If you’re using Windows or macOS Mojave or earlier, your device will show in the upper-left corner of the iTunes window. If you don’t see your device on your computer, learn what to do.

If you have multiple devices connected to your computer, click the device icon, then choose your device from the menu.

If your iPhone, iPad, or iPod touch is lost or stolen

If you lose your iPhone, iPad, or iPod touch or think it might be stolen, use Find My and protect your data.

Look for your device on a map

To find your device, sign in to iCloud.com/find. Or use the Find My app on another Apple device that you own.

If your iPhone, iPad, or iPod touch doesn’t appear in the list of devices, Find My was not turned on. But you can still protect your account if Find My was not turned on.

Mark as Lost

When you mark your device as lost, you remotely lock it with a passcode, keeping your information secure. This also disables Apple Pay on the missing device. And you can display a custom message with your contact information on the missing device.

Report your missing device to local law enforcement

Law enforcement might request the serial number of your device.

File a Theft and Loss claim

If your missing iPhone is covered by AppleCare+ with Theft and Loss, file a claim for an iPhone replacement.

Remotely erase your device

After you erase a device, you can’t track its location, so make sure that you no longer need to search for the device. If you have AppleCare+ with Theft and Loss, do not erase your iPhone until your claim has been approved.

Contact your wireless carrier

If the missing device is an iPhone or an iPad with cellular, report your missing device to your wireless carrier. Ask the carrier to disable your account to prevent calls, texts, and data use. And if your device is covered under your wireless carrier plan, file a claim.

Remove your missing device from your account

If you have AppleCare+ with Theft and Loss, do not remove your lost iPhone from your account until your claim has been approved.

Go to appleid.apple.com to remove the missing device from your list of trusted devices.

AppleCare+ with Theft and Loss is not available in all countries and regions.

Detect if device is iOS

I’m wondering if it’s possible to detect whether a browser is running on iOS, similar to how you can feature detect with Modernizr (although this is obviously device detection rather than feature detection).

Normally I would favour feature detection instead, but I need to find out whether a device is iOS because of the way they handle videos as per this question YouTube API not working with iPad / iPhone / non-Flash device

Detecting iOS

This might be the shortest alternative that also covers iOS 13:

iOS will be either true or false

Worse option: User agent sniffing

User Agent sniffing is more dangerous and problems appear often.

On iPad iOS 13, the user agent is identical with that of a MacOS 13 computer, but if you ignore iPads this might work still for a while:

The !window.MSStream is to not incorrectly detect IE11, see here and here.

Note: Both navigator.userAgent and navigator.platform can be faked by the user or a browser extension.

Browser extensions to change userAgent or platform exist because websites use too heavy-handed detection and often disable some features even if the user’s browser would otherwise be able to use that feature.

To de-escalate this conflict with users it’s recommended to detect specifically for each case the exact features that your website needs. Then when the user gets a browser with the needed feature it will already work without additional code changes.

Detecting iOS version

The most common way of detecting the iOS version is by parsing it from the User Agent string. But there is also feature detection inference*;

We know for a fact that history API was introduced in iOS4 — matchMedia API in iOS5 — webAudio API in iOS6 — WebSpeech API in iOS7 and so on.

Note: The following code is not reliable and will break if any of these HTML5 features is deprecated in a newer iOS version. You have been warned!

What to do When iTunes Won’t Detect an iPhone, iPad, or iPod

You’ve plugged an iPhone into a computer, and nothing happens. You look in iTunes, and the iPhone, iPod, or iPad isn’t there. Great, now what? What in the heck is going on?

Don’t worry, there are usually a few simple solutions that will resolve the problem and et your computer to detect the iPhone or iPad again, so try these tricks first in any whatever order works best for you.

7 Simple Tricks to Get iTunes to Recognize an iOS Device

Start with the the first five tricks, they are nice and easy, whereas the latter two tricks are slightly more involved and we detail those a bit more below:

• Quit and relaunch iTunes
• Connect the iOS device to a different USB port on the computer
• Reboot the iPhone, iPad, or iPod
• Reboot the computer
• Use a different syncing cable (if possible)
• Reinstall iTunes (read how below)
• Update the iPhone driver in Windows PC (read how below)

If you happen to be using a USB dock, skip the USB dock and try connecting the USB cable directly to the computer as well.

The last option is most relevant for torn and frayed cables and for those using the cheapy third party cables that seem to fail.

Did you complete those five easy steps and find iPhone or iPad is still not recognized by iTunes on the computer? There’s more to try including reinstalling iTunes, and for Windows users on PC to update the iPhone device driver – keep reading to learn how!

The iPhone/iPad/iPod is Still Not Detected, Now What?

If the iPhone, iPad, or iPod is still not recognized by iTunes, the next thing you should do is delete iTunes and reinstall it with a fresh version from Apple. That process is going to be different whether the computer is a Mac or Windows PC.

• Uninstall iTunes: In Mac OS X, iTunes is a protected app and must be uninstalled from the Terminal, in Windows it will be uninstalled through Control Panel
• Download and reinstall the latest version of iTunes from Apple

Reboot and try again, it should be detected now.

For iPhone / iPad Not Being Detected in Windows, Update iPhone Driver

For Windows PC users whose iPhone, iPad, or iPod touch is not being found or detected by iTunes or the computer, you can update the iOS Device Driver like so:

1. Go to the Device Manager in Windows, and locate “Apple iPhone” under portable devices section
2. Right click on the ‘Apple iPhone’ and choose “Update software”
3. Now click “Browse on my computer”
4. Navigate to C:\Program Files\Common Files\Apple… and choose the folder called “Drivers”

The updated driver will install and update and iTunes should now detect the iPhone, ipad, or iPod touch as intended.

That driver approach is for Windows PC, for Mac there is no driver to update in Mac OS X aside from iTunes and general Mac OS X system software, which is updated from  Apple menu > App Store > Updates.

iTunes & iPhone Still Not Working Together?

If you’ve done all the troubleshooting tricks above and the iOS device is still not detected, try connecting the iPad, iPhone, or iPod touch to a different computer and see if it’s identified. This can help rule out if the problem is with the original computer, or if it’s a problem with the iOS device itself. If it’s connected to another computer and still won’t be recognized, there could be a problem with the physical connector port on the iOS device itself, or some other hardware related issue, and you’ll probably want to call Apple to sort it out. Before doing so, be sure to back up the device manually with iCloud, since iCloud will be able to backup important data in iOS even if the device can’t connect to a computer.

Thx. It’s the solving of my problem i have been looking for this week. I reintalled iTunes.

Absolute legend! Thank you so much, this works.

Thank you, only place that had real advice that worked. now, i can back up my phone to my computer with itunes instead of just getting lambasted with music sales.

I can’t connect icloud/itunes in my iPhone

Hi I need a sim card for my phone and connect to itunes.

Then get a SIM card and put that in your iPhone so you can activate it with iTunes. That has nothing to do with iTunes not detecting the iPhone.

Hi I need to eat lunch.

Hahaha .. :)) Perfect Reply !! can’t stop laughing tbh .. xD

Thank you for the help! 🙂

Itunes on my MacBook Pro would not recognize my iPad. All I had to do was download and reinstall the latest version of Itunes (https://www.apple.com/itunes/download/). After the install, Itunes told me a new download was required to recognize my iPad. I installed the download, and now everything works perfectly!!

Mojave just came out with this latest version of Itunes but the Mojave install keeps failing on my MacBook.

JJ, Yes great point, being sure you have the latest version of iTunes installed on the computer is often an easy remedy to issues where iTunes will not detect an iPhone or iPad. Thanks for sharing your tip and experience!

thank you so much , updating driver was so helpful

Thank you soooooooooooo much. That was such a simple solution [#2].

All is well now 🙂

Thanks so much for this. iTunes was recognising my device earlier on today but then stopped. I’ve been trying for hours to sort it out and discovered this. I updated the phone driver following your instructions and it worked straight away. Much appreciated!!

Excellent article. It works for me:)

Thank you so much. This actually helped me unlike the iTunes website. Thank you so much. You have no idea with how much you saved me with this problem!! 💞💕

Wow, finally got a good link to info. Thanks for this post! Tried many things, but this worked immediately.

Too bad apple can’t get this on their help site.

P.S. For Windows 10, it will show “Update driver”, which is basically the same thing.

Thanks for your help. The update iPhone driver in Windows 10 device manager worked. The driver failed after an iTunes update yesterday. Someone took an extra byte out of the apple.

Worked for me post driver update. many thanks

Thanks! I updated the drivers and it worked instantly!

this worked for me thank you very much
Go to the Device Manager in Windows, and locate “Apple iPhone” under portable devices section
Right click on the ‘Apple iPhone’ and choose “Update software”
Now click “Browse on my computer”
Navigate to C:\Program Files\Common Files\Apple… and choose the folder called “Drivers”

thank u very much. I updated driver and it worked. Pleasured that 🙂

Been searching everywhere for this solution! Only connected ONCE and couldnt connect any longer. This article helped alot, thanks a bunch!

This fixed my issue connecting an iphone SE and ipod to latest version iTunes on a Windows 10 laptop with usb 3.0:

Follow these steps to reinstall the Apple Mobile Device USB driver:

Disconnect your device from the computer.

Reconnect your device. If iTunes opens, close it.

Press the Windows and R key on your keyboard to open the Run command.

In the Run window, enter:

%ProgramFiles%\Common Files\Apple\Mobile Device Support\Drivers

Right-click on the usbaapl64.inf or usbaapl.inf file and select Install.

You might see other files that start with usbaapl64 or usbaapl. Make sure to install the file that ends in .inf. If you’re not sure which file to install, right-click a blank area in the File Explorer Window, click View, then click Details to find the correct file type. You want to install the Setup Information file.

Disconnect your device from your computer, then restart your computer.

Reconnect your device and open iTunes.

(see the part that says: “If you use a Windows PC”)

Thanks for providing the instructions. Right after updating the driver things started working as expected.

Just want to say thank you for this! I have a new iphone and can finally sync everything!

I have recently upgraded my computer and have had no end of problems with iTunes, first it would not accept songs, then only when the HDD was connected to a different computer on the network, now since I have removed and reinstalled iTunes it wont recognise a previously recognised iPod, tried all the steps multiple times but not wanting to reinstall again as I have spent about 10 hours creating a playlist

FINALLY it works. I have new everything. Driver is OK and up-to-date. I did all the above, and iPhone seen by laptop but not iTunes.

The magic was to uninstall on my Windows 10 laptop all apps that are “Apple”. Then install the newest iTunes.

I did a restart, and after that plugged in my iPhone usb to the laptop. It immediately opened iTunes with the error saying I need to enter my passcode to unlock my iPhone.

Now it is seen by iTunes.

so i’ve updated the driver, but now i cant find my iphone folder in my usual file explorer location. is there a way to change the driver back to its original settings?

Awesome, thank you. The one thing I had not tried was re-installing the device driver for the iPhone. Worked great. iTunes immediately recognized the iPhone 7 Plus

I went into device manager in windows found iPhone USB drive uninstalled it, reconnected my iPhone, the driver installed and it works hope this helps others.

The Device Manager for Windows solved my problem! Thank you! For me, the exact driver path is C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers

if you’re reading this you already wasted your money. quick return that piece of junk apple product you bought. I only used one computer with my tablet, new cable, all latest software, restarted everything. this thing N…E…V…E…R works. it’s like their goal is to make the newest apple product even worse than the last

I have tried all the fixes and my wife’s iPhone 6 will not synch (will charge) but mine will no matter what cable I use. I have redownloaded iTunes, rebooted laptop, rebooted phone, tried many cables, and yes have updated the driver even though it is always the latest and like I said my iPhone 6 synchs great but hers will not.

Thank you. Your information about how to reinstall the correct driver did the trick. I was so frustrated with iTunes, and this turned into an easy fix because of your site. Thank you.

i have been install latest verison of itunes for unlock my disabled iphone,i launced itunes and do these process to unlock it ,but my iphone CAN’T dedected……whyyy? reply quickly

I’m not the type of person who log in to say thank you.but thank you so much.you are the only site that’s helpful and has suggestion that works so far.❤️❤️❤️❤️❤️❤️

For Windows 10, if your iPhone or iPad is not detected by iTunes, here is how you can fix it. It works!

How to fix when iTunes doesn’t detect iPhone, iPod, iPad on Windows 10

– Go to Control Panel > System > Device Manager > Portable Devices > Apple iPhone > right click and choose “Update Driver Software”

– Now choose “Browse computer for computer software” then choose “Let me pick from a list of device drivers on computer”

– Now navigate to the following driver path for Apple devices:

/Program Files/Common Files/Apple/Mobile Devices/Drives/usbaapl64.inf

Choose “next” a bunch so it chooses the driver and updates the Apple driver. Now relaunch iTunes when the driver has finished installing and iTunes will find your iPhone / iPod / iPad again. Done.

Thanks Brainy Guy – saved me a lot of work! My only change was I didn’t go directly to the usbaapl64.inf file, I had to choose the “Drivers” folder. But it found what it needed and updated.

thank you so much

I just followed Apple’s support instructions to locate and install the Apple driver and bypass the Windows 10 standard driver. Even though you don’t have a disk, the instructions cover that beautifully. It solved the problem of my iPad and iPhone not being recognized on a new Win 10 laptop.

Thank you. I have spent all night looking for answers. I found many suggestions that didn’t work. But this worked!!

Not all heroes wear capes.

it must be two or three weeks. ipad air wasn’t charged so i charged it and instead of turning on it got stuck on apple logo for a whole day then i tried turning its logo screen off….eventually putting it in dfu mode….connecting to pc. it only states ipad needs to be restored and doesn’t give option to update instead….yesterday…while pressing ipad butons it showed connected to itunes logo and gave me option t update….but for either update or the restore that i clicked before the download of ios never completes….and i don’t have the back up of my data….plus…the ipad never gets past the logo which apppears and dissapears itself…and it keeps showing the getting charged symbol….for weeks now….so i have to keep it plugged because otherwise it shows connnect for charging symbol…help pleaseee

THIS WORKED! I tried everything I could find on the Internet to fix this issue with my iPod, but none of them worked. I had already succumb to the idea that I would have to purchase a new iPod, BUT this fixed the issue and iTunes now recognizes my iPod when I connect! THANK YOU.

I tried all these tips, didn’t work. I went to look for the driver on c drive as described above and there’s no driver folder

Amazing !! Thankyou . .You ROCK 😀

Thank you so much! Have been searching online to fix this issue for hours & your tip on reinstalling the driver via the Device Manager worked a dream.

For Windows PC users whose iPhone, iPad, or iPod touch is not being found or detected by iTunes or the computer, you can update the iOS Device Driver like so:

Go to the Device Manager in Windows, and locate “Apple iPhone” under portable devices section
Right click on the ‘Apple iPhone’ and choose “Update software”
Now click “Browse on my computer”
Navigate to C:\Program Files\Common Files\Apple… and choose the folder called “Drivers”

This solution fixed it for me thanks a lot! My problem was that I was that I didn’t navigate to “C:\Program Files\Common Files\Apple” thanks a lot for this!!

All you do is find the apple iphone icon in device and delete it and then unplug and plug in your phone to the USB and the driver will install again and thats it!

Neither of our (wife/I) iPhone6’s will come up in iTunes on our new Dell computer running Windows 10. We have the newest iPhone update (iOS 10.0.1), newest iTunes update and have uninstalled iTunes and reinstalled a few times with no success. Have rebooted the computer…….no luck. Done everything that I’ve read online to do, but neither iPhone will come up.

Now, both do come up on our laptop running Windows 7. So, I do know that the problem is not with our iPhones. But, don’t know what will happen when we either get rid of our laptop and buy a new one that has Windows 10 in it or possibly upgrade our existing laptop to Windows 10. All I know is, if we change our laptop and I can’t sync either iPhone with it, we could be “up a creek”. And, when the times comes to buy a new iPhone, we won’t be able to use a computer to download the things that were on our iphone6.
Any ideas of what to do would be great helpful.

its really helped. thank you so much! XD

Thank you so much!! your tips on reinstalling the iphone driver worked!! Much appreciated.

Ok, so I haven´t read the other comments, but I followed all the steps and iTunes still wouldn’t detect my iPhone. I tried uninstalling iTunes multiple times and reboot my computer, but this wouldn’t make a difference.
In the end I had to uninstall Apple Mobile Device Support along with iTunes through my Control Panel, and as I reinstalled iTunes, Apple Mobile Device Support would be reinstalled on my computer. Only then, as iPhone was plugged in to my computer, iTunes notified me that my iPhone could not communicate with iTunes because the software was prohibited to show the iPhone due to my codes and I had to trust the computer the iPhone was plugged in to.

you sir are my hero

Updating the iPhone driver did the trick for me!

Thank you so much for this, I tried everything Apple had on their website but it didn’t work. This worked like a charm.

I’ve been trying to fix my iTunes/iPhone syncing issue since March! The troubleshooting this site offered helped!
Thank you very much.

I tried all types of advice. Finally I plugged my phone to my PC. Went to device manager. Portable devices. It recognized my iPhone there. I went to drivers and clicked uninstall. Unplugged my phone, plugged it back in and it worked. Hope this helps

it helps man. really. it saves me from reading this confusing tread. thanks

Thank you so much for this article. It worked beautifully and I’ve been trying to fix this issue for weeks. Better than Apple support! MUCH appreciated and very clear directions. Thank you!

Nice! It works on my iPad but my iPhone still can not connect to PC.

Will these troubleshoot tricks work when computer states we need the latest version of the software? Because my computer has the latest updates available for the actual computer and iTunes- but iTunes still states it needs the latest version?

Would just like to say thank you so much! Without your website I couldn’t have worked it out. Literally I am just so grateful. THANK YOU!!

Thanks! Worked perfectly, so grateful too! 🙂

If you’re like me and none of the above has worked here’s what you need to do . I just figured this out after synthesizing everything up above :

1. Go to your device manager. You can do this by clicking the magnifying glass in Windows 8 or searching your C Drive in Windows Explorer for earlier versions by typing in devmgmt.msc Double-click on it to open it up
2. Under universal serial bus controllers double-click on Apple Mobile Device USB Driver. Click on the Driver tab. Go to the bottom and click on uninstall 🙂
3. Now right click on Universal serial bus controllers again. Click ‘scan for hardware changes.’
4.it will now reinstall the current driver that you just deleted.
5. Your phone should now get recognized by your computer and click Allow
6. Now you can click on your Apple iPhone in Explorer.

Thanks everybody up above for the ideas.

i am trying to do whatg you have listed there i got to number 2 and my computer does not have the apple mobile device usb

Nothing was working for me… then I used a hair dryer and blew air inside the iphone 5 dock connector, plugged it back to the usb port and it was recognized by windows 10.

Thanks, Prism! The step by step helped me out and worked!

Do this:
iPhone Fix; For those that can’t connect iPhone on win 10! Try this!
plug in all usb ports until you can see the phone in the icon “safely remove hardware and eject media” (for short, “usb eject icon”) To see, right click on “usb eject icon” and click open devices and printers. Look under Unspecified. Right click on iPhone or apple device then, properties, hardware, properties again, change settings, drivers, update driver, browse my computer for driver software, click browse and look for C\ program files\ common files\ apple\ mobile device support\ drivers. click ok, Done!

Dude! You rock! I was just about to toss this damn Windows 10 into the river and go back to a Mac! Thank you!!

iPhone, iPad, or iPod not recognized in iTunes for Windows
If your iPhone, iPad or iPod won’t connect to iTunes on your PC, try the steps below.

Use these steps if your iPhone, iPad, or iPod doesn’t appear under Devices in iTunes after you connect it to your Windows PC. When trying these steps, don’t manually place the device into recovery mode. You also might have seen one of these messages:
The device can’t be restored in iTunes.
A “!” or “?” symbol, plug symbol, or “X” appears next to the device’s entry in Device Manager.
During an update or restore, the device might no longer be recognized by iTunes.
If you’re using a Mac, learn what to do if your device isn’t recognized in OS X.
Restart

Turn off your computer and your iOS device or iPod, then turn them on again.
Update your computer

Check to make sure that you’ve installed all required updates for your computer.
Update iTunes

Check that you have the latest version of iTunes installed on your computer.
Make sure your iOS device trusts your computer

If you connect your iPhone, iPad, or iPod touch to your computer and see “If you have not connected your iOS device to this computer before, unlock the device and tap Trust,” make sure that your device trusts the computer.

If you use Windows XP and you see the trust alert on your device repeatedly, make sure that you installed iTunes. Learn how to resolve a repeating trust alert when using Windows XP. You might need to reset the lockdown folder.
Check the USB cable

Verify that the 30-pin to USB cable or Lightning Connector to USB cable is free of debris and not damaged. If another cable is available, test with that cable instead.
USB cables that are bundled with third-party products or accessories might work only to charge those products and might not transmit data. Also, if you’re using a third-party case or extended battery pack, try removing the case and connecting the Apple-supplied USB cable directly to your device.
Verify that Apple Mobile Device Support is installed

iOS devices require Apple Mobile Device Support, which should be automatically installed with iTunes. To verify whether it is installed, follow the steps appropriate for your Windows operating system below.
Windows 8
Move the cursor to the upper-right corner and click the magnifying glass.
Type Control Panel, and press Return.
Click “Uninstall a program.”
Verify that Apple Mobile Device Support is visible in the list of currently installed programs.
If Apple Mobile Device Support isn’t listed, remove iTunes, QuickTime, Apple Software Update, Apple Application Support, then reinstall iTunes.
Reinstall iTunes for Windows XP
Reinstall iTunes for Windows Vista, Windows 7, or Windows 8
If you reinstall iTunes, and Apple Mobile Device Support still isn’t installed, you can resolve issues installing iTunes for Windows.
Windows Vista and Windows 7
Click Start.
Choose Control Panel.
Click “Uninstall a program” (if you’re using Windows Vista’s Classic View of the Control Panel, click “Programs and Features”).
Verify that Apple Mobile Device Support is visible in the list of currently installed programs.
Windows XP
Click Start.
Choose Control Panel.
Open the “Add or Remove Programs” control panel and verify that Apple Mobile Device Support is visible in the list of currently installed programs.
Restart the Apple Mobile Device Service

Click the Start menu, right-click Computer, and choose Properties.
In the upper-left corner, click Device Manager.
For Windows 8, move the cursor to the upper-right corner, click the magnifying glass, type devmgmt.msc, and press Return. The Device Manager window should open.
Click the plus (+) icon (or disclosure triangle ( ) (for Windows 7 and Windows 8) next to “Universal Serial Bus controllers” to expand this selection.

Locate the Apple Mobile Device USB Driver. If this entry is displayed without a down arrow, “!” or “?” symbols over it, then this driver is successfully installed. Continue to “Check for third-party software conflicts”.

If the Apple Mobile Device USB Driver isn’t listed, continue to “If the Apple Mobile Device USB Driver is not listed.”
If you see a down arrow next to the device’s entry, then this device is disabled. To enable this device, right-click it and choose Enable from the shortcut menu.

In the resulting dialog box, click OK.
In the Device Manager window, right-click “Universal Serial Bus controllers” and choose “Scan for hardware changes” from the shortcut menu.

Windows automatically reinstalls the necessary drivers and attempts to remount the device.
If the Apple Mobile Device USB Driver entry still has an exclamation mark or question mark over it, right-click this entry and choose Properties. Under the General tab, look beneath “Device status.”
If you see a message that reads: “Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
