The Touch ID is integrated into all iPhone from the 5s onwards and at all the iPad from 2 Air or iPad iPad mini 3 onwards. It is a technology which at first did not call much attention, but that over time has shown that it is tremendously useful and helps us to be more agile with our devices.
Thanks to Touch ID we can unlock quickly with our fingerprint devices, confirm purchases in the App Store, make payments via Apple Pay (in countries where it is available) or use apps like 1Password without needing to enter unlock password on every website to which you want to access.
All this use makes sensor have to endure intense use, what you can do that in certain cases Touch ID fails and not work properly. In the following lines we will discuss the most common solutions when Touch ID presents problems, generally performing these steps the sensor returns to function normally when there are problems and will not take us more than a few minutes apply solutions.
Problems with Touch ID? Here are the most common solutions
Clean the sensor
In some cases Touch ID problems can be solved simply with a cleaning. Any residue on the surface of the sensor can be made to read evil our fingerprints and that cleaning can solve these errors.
For this purpose it is better use a soft cloth which non-shedding on the iPhone or iPad home button. Best thing is not to use any chemical product and do it with dry cloth.
Recalibrate Touch ID deleting fingerprints
Delete all the fingerprints that we have stored on our iPhone or iPad can also be an effective solution. The idea is to remove the existing tracks and add them again. In this way we get re-zero the sensor and often solve problems.
To delete the tracks must go to settings – Touch ID code, enter each of the stored tracks and playing on delete fingerprint. Instead of entering each of the tracks also we can slide finger from right to left on each of them and touch on the deletebutton. The result in both cases is the same.
Once removed all traces we must re-create them. It is recommended use the five available, so in the event that it fails any can resort to another finger and continue using the device.
To add fingerprints, on the same screen where before we delete them we must touch on a trail and follow the directions onscreen to the letter.
Restart the device
Force a reset of the device, or simply restart, can also solve problems of this type. A reboot makes all software processes to close and return to start loading the operating system again, by what should be a software failure that can fix it.
Here we explain how to force reboot or restart the device normally.
Restore the computer to factory State
If at this point continue with Touch ID problems is possible to restore to solve the problems. In doing so we will return the iPhone or iPad to factory State, so it is very important to make a backup completes before anything.
Once the backup we will restore the device and check if Touch ID works normally with the newly installed operating system. It work we will know that it was a failure of software and can retrieve the backup device to keep all of our data and configurations.
They continue the problems after performing the above steps?
If after completing the previous Touch ID still failing, it is likely that in the case of a hardware failure. In this case we will be forced to go to a service center to review the device and give us a solution which probably will replace the parts damaged by new ones.
