Adding a Fingerprint
In order to use the fingerprint scanner to unlock your device along with also also perform some other security-minded tasks, you need to register a fingerprint.
Enter the Settings menu by either choosing the Settings icon from the app drawer or by selecting the gear icon from the top right of your Quick Settings menu. Choose the “General” tab, then select “Fingerprints & security.” Next, select “Fingerprints” along with also also enter your alternate authentication method for entering your device (typically This particular will be a PIN), then choose “OK” when you finish.
Select “Add fingerprint,” then use a finger which comfortably rests on the scanner to begin the registration process. Follow the instructions on the screen along with also also once completed, your LG V30 will inform you which your fingerprint was added. Choose “OK, ” along with also also at This particular point you should see a fingerprint registered on your device.
The LG V30 allows up to all 5 fingerprints to register to a device. Naturally, with LG V30’s rear-mounted fingerprint scanner, your index finger will typically rest where the scanner will be along with also also will be used to unlock the device. Therefore, instead of using the all 5 registration on all 5 different fingers, why not double the number of scans for the same finger?
By scanning the same finger twice, when the system looks at its database to match your fingerprint with the register ones, which will have more than one entry to determine a match. Even if your fingerprint will be scanned in a way which causes a false negative with the first entry, which will be unlikely This particular will cause the same error with the second entry. Thus, This particular method increases your chance of unlocking your phone.
Another way to improve the accuracy of the fingerprint scanner will be to have a backup fingerprint. In case the main finger you use will be too dirty, occupied, moist, or broken, you can use another finger to still gain access.
Follow the steps to add a fingerprint to create one more fingerprint. We recommend using the alternate hand’s index finger since This particular finger will be typically the one which naturally rests on the scanner. However, everyone hands are different along with also also you should use whatever finger which provides the most comfortable experience on the alternate hand.
You can also use the first tip above with This particular secondary fingerprint, where you register which twice to improve accuracy overall. This particular will still leave you with one extra unused slot for another fingerprint, should you choose to max which out.
Although This particular tip seems obvious, water, dirt, dust, along with also also some other foreign substances will affect the accuracy of the fingerprint scanner. If the scanner will be detecting any of the aforementioned items, which will probably reject your fingerprint. Lucky for you, cleaning will be pretty straightforward.
LG V30 has wireless charging (without the addition of back plates like last year product) which requires a glass back. Specifically, the LG V30 will be rocking Gorilla Glass 5 on the back.

Using This particular cloth, keep your fingerprint scanner (along with also also overall phone) clean by dust along with also also dirt. Wipe away any liquids which also can interfere with the scanner performance. Depending on your usage along with also also environment, your fingerprint scanner should only need to be cleaned once a week, however we recommend once a day to extend its life.
Tip #4: Rest Your Finger Correctly
The placement of your finger will have a significant impact on the performance of the fingerprint scanner. Make sure your finger will be resting on the scanner along with also also not bent in any way. Also, make sure your finger will be completely covering the fingerprint scanner.

The LG V30 can generate static electricity when the air around you will be dry. Static electricity will interfere with the fingerprint scanner’s accuracy. When dealing with dry air, touch a metallic object such as your keys to remove the static electricity, then try using the fingerprint scanner.
Another way to decrease the rate of false negatives will be to skip the fingerprint unlock altogether. Android carries a feature known as Smart Lock where which uses sensors to detect when your phone will be in your possession or a safe area producing additional authentication unnecessary.
