Almost all iPhone users know what Touch ID is and what its purpose is. For those who do not know, Touch ID is a method for authenticating your identity on an iPhone or iPad. This method allows you to unlock your iPhone using your fingerprint. You can also make purchases and recall passwords (if saved) by simply scanning your fingerprint.

Unfortunately, some iPhone users are having trouble with the Touch ID. It is either that they are unable to set it up or their device is unable to scan their fingerprint. In this article, you will be able to read some methods that will help eradicate the issue.

Addressing the Touch ID Issues:

First, you need to ensure that you are doing it right. Head to the settings on your iPhone and tap on the option Touch ID and Passcode. Enter the passcode you are using for unlocking the iPhone and then try setting up the Touch ID from scratch. If this simple repetition doesn’t help then it means that you have to look up for some troubleshooting techniques. Follow the tips mentioned below. Make sure you follow them in the order stated below.

Fingerprint Reader and Finger Should be Dry:

Start the troubleshooting with a very basic technique. All you need to do is to ensure that the home button and your finger is dry while activating the Touch ID. The sensors in the device are so sensitive that a tiny bit of water or sweat on the home button or your finger will not let you activate the Touch ID. Use a soft, lint-free cloth to dry the home button and your finger and then try activating the Touch ID. Make sure that you also clean the grime circling the home button or else it won’t let you activate the Touch ID.

Do it properly:

You must activate the Touch ID properly. Place your finger gently on the home button and do not put extra pressure. Do not move the finger while it is placed at the home button or else it won’t work. There is an Accessibility setting that changes the method a little. If this setting is enabled then you may have to rest your finger on the reader and then press the Home button once to unlock your iPhone. You can change this setting by:

1. Go to the Settings on your iPhone.

2. Tap on the option Accessibility.

3. Hit the option Home Button and then adjust the settings accordingly.

Delete the Existing Fingerprint & Set-up Again:

Sometimes, the Touch ID setup doesn’t get completed successfully. In that case, Touch ID won’t be able to function properly. The best way to deal with this problem is to erase the existing fingerprint and set it up from scratch, again. Here is what you will need to do:

1. Go to the Settings on your iPhone.

2. Tap on the option Touch ID and Passcode.

3. Now tap on the option Delete Fingerprint.

4. Once it is removed, restart your device and then enroll a new finger.

Update your iOS:

Apple keeps reminding its users to update the software as soon as the update is available. However, many iPhone users tend to delay the updates for no reason and end up running themselves in trouble. Unnecessarily delaying the update affects the overall functionality of the iPhone and it could well be the reason why your Touch ID may not be working properly. The simplest way to ensure that outdated software isn’t the cause, you need to follow the steps below:

1. Go to the Settings on your iPhone.

2. Tap on the option General.
Software Update

3. Next, tap on the option Software Update.
install the latest version of the software

4. Now download and install the latest version of the software.

 Reset Network Settings or All Settings:

Sometimes, it is just the network settings or the settings of your iPhone that are causing this trouble. A few lucky iPhone users merely reset the network settings or reset all settings on their device and it helped them in addressing the issue. Sire, the probability of this method to work is quite low, but it is worth a try. Here is what you need to do:

1. Go to the Settings on your iPhone.

2. Tap on the option General.
Reset

3. Scroll down to the bottom of the screen where you will find the option Reset. Tap on this option.
Reset Network Settings

4. Now choose the option Reset Network Settings. If this method works, great. If not, then try Resetting All Settings and see if helps the cause.

Force Restart Your Device:

Surely, you may have tried restarting the device a couple of times to address this issue. Restarting the device usually does the trick. However, if a simple restart fails to deliver, you should consider performing the force restart. It is also known as soft reset and it helps in eliminating the bugs that are affecting the performance of the device. Force restart doesn’t delete any data on your device so you do not need to create a fresh backup before that. Here is how you can force restart different iPhone models.

For iPhone 8 or Later:

Quickly press-release the volume up button, then press-release the volume down button in quick succession. Once done, press-hold the sleep/wake button until the Apple logo appears on the screen.

For iPhone 7 & 7 Plus:

Press-hold the sleep/wake button in tandem with volume down button for at least 7-10 seconds. Do not release them until the Apple logo appears on the screen.

For iPhone 6 Plus & Previous Models:

Press-hold the home and side/top button (as per the model) for 10 seconds. Do not release them until the Apple logo appears on the screen.

Erase All Content and Settings:

If force restart fails to deliver then restore to factory settings could be your last hope. Many iPhone users try to avoid restoring the device to factory settings as it wipes out all the data on your iPhone. All the Settings are set to default and you will need to set up the phone from scratch. It is one of the daunting troubleshooting techniques, but at the same time, it is a proven one when it comes to addressing the major issue. The steps are quite simple to follow.

1. Go to the Settings on your iPhone.

2. Tap on the option General.

3. Scroll down to the bottom of the screen where you will find the option Reset. Tap on this option.

4. Now choose the option Erase All Content and Settings. Provide your passcode and let the iPhone finish the process.

5. Once the iPhone is ready to use, you will need to restore your data using either iCloud or iTunes backup depending on your feasibility.

Restore via iTunes:

If for any reason, you are unable to restore the iPhone to factory settings via the Reset option then you can use iTunes as an alternative. The process is quite simple, and here is what you need to do:

1. First, connect your iPhone to your computer/Mac using the original charging cable.

2. Launch the iTunes on your Mac/PC.

3. Hit the Summary tab.

4. Now create a backup using the option Backup Now.

5. Once done, hit the option Restore.

6. Once the process is completed, your iPhone will restart and you will need to set it up. Make sure you recover the data using the backup.

Bottom Line:

All the aforementioned methods are proven methods for addressing the Touch ID related issues. Restoring the factory settings will help the cause. If everything fails then it could well be a hardware problem and you may need to take your iPhone to an Apple Store or a reputable repair shop.
