This week's machine room, small knitting to talk to you about the iphone fingerprint identification Touch ID problems. Have you ever experienced a Touch ID failure? A good fingerprint identification is not recognized, pit dad it!? Don't worry about this situation, we need to discuss it in a separate situation.
Touch ID fails after reboot
The first and most common is the iphone reboot after the fingerprint identification failure. The
first thing you need to know is that the iphone's Touch ID fails after the reboot. Why, then, does Apple have to restart the iphone before fingerprint recognition works directly?
This is because, for security reasons, the iphone's fingerprint identification System Touch ID does not store your fingerprints, and simply your fingerprints are stored in the iphone's chip after being converted into digital. And this part of the chip is encrypted to protect, only your fingerprint and password can be activated to use.
In other words, when your iphone reboots, the chip-protected Touch ID is quarantined and not activated. Must be enabled with a digital password. So, when you restart your iphone's Touch ID, don't panic, just type in a password and you can use it.
There's no need to worry about these kinds of things
In addition to restarting the Iphone,touch ID, there are some cases where the iphone's fingerprint identification system will not work, and this is normal, don't worry, just enter the password once.
One situation is that the iphone has been locked for 48 hours without unlocking it, and there is a situation when you go to Settings-Touch ID and password to make the relevant settings.
Is there a problem with the external Touch ID in addition to the above?
If there are problems with your iphone's fingerprint identification system, you might want to try this focused approach:
Upgrade to the latest iOS system, the latest iOS system has the most complete support, and will fix a number of errors and bugs.
Please dry the hands and screen to ensure that the hands and screen are kept dry, water most affect the work of Touch ID stability and accuracy. In addition to moisture, emulsion, perspiration, grease, wound or dry skin can affect fingerprint identification. Certain activities may also temporarily affect fingerprint identification, including movement, bathing, swimming, cooking or other conditions or changes that affect fingerprints.
If you use a protective shell or screen protector, the main screen button and the surrounding ring must be fully exposed. Otherwise, remove the protective shell or screen protector and try again.
Enter the set-touch ID and password, and then test the fingerprint identification system, and whenever you put a finger on it, if the finger is already registered, the corresponding finger button will light up to show that the finger has been registered. You may wish to try again by registering a finger.
if the above method has been used, the Touch ID still does not work, then you need to go to Apple after the hardware overhaul. The above is the current phase of the machine room for everyone ramble about Touch ID two or three things, how, also need it!
