Using the fingerprint sensor is the fastest way to unlock a phone, according to everyone. The phone may be unlocked in a matter of seconds, allowing for immediate use. Since fingerprints are easier to guess than passwords and are less likely to be altered, the scanner adds a rather complex layer of security. What if you discovered that your LG V30’s fingerprint sensor is not functioning?
It appears that other users have reported having the same problems. The sensor’s downtime could last a short while or be prolonged. You can use the troubleshooting techniques listed below.
1: Check if your Fingers are clean [ Fingerprint sensor not working on LG V30 ]
A sophisticated device that scans fingerprints and grants access after authentication is the fingerprint sensor. Even if you are the phone owner and use the appropriate finger in the proper manner, damp, dry, or filthy fingertips can prevent a fingerprint sensor from recording the stimuli and since the sensor was unable to validate your fingerprint, it won’t operate.
To clean your finger before attempting again, use a napkin or tissue. We often advise registering two or three fingers so that you can still unlock your LG V30 with your middle finger or thumb if your index finger gets dirty.
2: Check if the Fingerprint sensor is clean
It’s time to take care of the fingerprint sensor, assuming your finger is clean. It will have trouble authenticating the user if it isn’t clean. Oils, liquid, or any other substance partially or completely covering the fingerprint sensor will affect its ability to record a touch, making it harder for you to open your LG V30 in this method.
To clean the module, use a tissue or a lightly moistened cloth. It goes without saying that you shouldn’t remove the debris that has accumulated on the module with hard or sharp things like keys because doing so will just increase the damage.
3: Reboot the phone [ Fingerprint sensor not working on LG V30 ]
Do not assume that this approach won’t work in this situation. It turns out that transient software issues can make the phone’s fingerprint scanner act strangely, such as by failing to recognize a fingerprint. So, after a fast reboot, you may truly start to remedy this momentary software issue.
4: Software Updates
It is advisable to periodically update outdated software to remove any issues from your LG V30. You may be experiencing problems with the fingerprint scanner not working due of outdated firmware.
Checking to see if there is an update available won’t take long. If so, all you need to do is download and instal it using Settings >> About Phone >> Software Updates (System Updates).
5: Wipe cache partition [ Fingerprint sensor not working on LG V30 ]
You must boot into recovery mode before using this particular technique. We strongly advise against using this technique if you aren’t comfortable doing so. If you’re ready to continue, you can use this feature to delete the system cache on your LG V30. Here’s how it functions.
- Shut down your LG V30.
- The recovery mode must be activated. Use the Volume UP + Power or Volume DOWN + Power buttons, as appropriate. Keep pressing the buttons until the phone enters recovery mode.
- Change between settings by using the volume rockers at this point. For selection, press the power button. Notably, this instance lacks a functional touchscreen.
- Choosing “Wipe Cache Partition”
- It is finished by saying “Reboot the system immediately.”
6: Reset your LG V30
This approach resembles firing the final shot into the victim’s head. This is due to the fact that after a reset of your LG V30, all previously stored data will be lost. We don’t advise using this procedure without a data backup.
- Go to Settings first.
- Reset Options >> System >> Next Destroy all data (factory reset).
- The decision to proceed or not will be presented to you. Finally, input the password to confirm and start the reset operation after selecting “Erase All Data” to indicate your agreement.
7: Report the issue
It’s time to bring in the big guns if you are still having trouble getting your LG V30’s fingerprint sensor to function. We are referring to seeking assistance from a certified technician at the approved service location for your phone. Although you run the risk of voiding the device’s warranty, you can still report the problem to a nearby service center.
These are some of the troubleshooting techniques you might apply to resolve the LG V30’s malfunctioning fingerprint sensor issue.
