Security methods are key in the daily use of smartphones, among them the fingerprint sensor is the most popular as it provides us with a fast and very reliable average. This however is not without some problems that we have encountered when unlocking Samsung phones with the fingerprint reader both on the screen and on the back.
These problems extend to all price ranges, making them common problems that with One UI and with different tips we can solve. Before going directly to our problem with the fingerprint reader, we recommend you alternate and try the alternative oscillations in other problems because it could be the case that we personally work for us.
Fingerprint sensor does not respond on Samsung
When we try to unlock the Samsung mobile with the reader on the screen or on the back and it does not work, we should not worry, it is something very repeated among users and that in most cases the solution is simple. By trying it more times we will not find the key since it is not even vibrating or trying to unlock the device.
Safe mode fixes the problem
With One UI safe mode many users have managed to fix these fingerprint reader bugs . Some application is the one that could be preventing its use and with this dome it will be disabled so that we can use it again. Once we have verified it, we just have to uninstall the latest installed apps and make sure that it does not repeat itself in this way.
To access this mode on Samsung phones what we must do is turn off the terminal or restart and keep the power button pressed while it starts until we see the Samsung logo. Then we will hold down the volume down button and when it finishes turning on we will see in the lower corner the safe mode.
Dry the mobile completely
Mobiles are not good friends with water or humidity and that is why if we have taken advantage of the water resistance of some Samsung models , we must remember to dry it completely. It is likely that after the dip it requires an extra drying time and then the reader should return to normal operation.
Spot failures with the fingerprint sensor
If in our case we only sometimes have a problem with unlocking with the fingerprint sensor , the solution may be different. These specific failures could come from a bad figuration or from a malfunction due to the wear and tear of the reader itself, even so we will try to find the correct solution.
Reconfigure the fingerprint reader
The first thing we must try to find the solution to the problem to unlock Samsung phones is to reconfigure the fingerprint. For some reason it may have been misadjusted, making it unable to unlock the device no matter how hard we try. It is recommended not to try it continuously and the first thing we should do is access with the alternative pattern or pin to follow these steps:
- We enter the mobile settings.
- We choose the Biometric Data and Security option.
- We click on fingerprints.
- We remove the traces and add them again.
To finish we can check the fingerprints added in the option that seems to us, in this way we can check first hand if the reader has a fault when the smartphone is locked.
Repeat your footprint if necessary
If we continue to encounter the problem with a single fingerprint, we can keep the same finger in different positions as many times as necessary. This mechanism will be of great help to us so that the problems do not recur.
Put your finger in the right position
Whether we have the fingerprint reader on the back of the mobile or on the screen, we can fail to place it and this means that it does not manage to unlock us as it should. We must pay attention to whether this is a position error or on the contrary it is a fault of the fingerprint reader to choose other alternatives that we show you to fix it.
Slow unlock with fingerprint sensor
There are other cases where the fingerprint sensor works and is not failing but it is only much slower than it should be. In these cases the problem is very different from that of other Samsung mobiles and following the steps that we show you will be very important if we want to improve the response time of the fingerprint reader.
The problem is in the protector or your fingers
Screen protectors are not very friendly to the fingerprint readers on the front , this can make a quick response very difficult since the sensor is in a more complicated situation for the light that checks our physical finger lines can read them correctly. In this case, what we should do is opt for another protector, something that we can verify by just unlocking the mobile when removing it.
The fingers are also key beyond the position, the dirt on the fingers if we use the mobile in physical work or during sports, it can take much longer to allow us to access the mobile.
Update your mobile
Last but not least, updates to our Samsung mobile are very important to correct security errors and protect us, but they also help to improve the results of the fingerprint blocking in One UI . Just by accessing the Settings> System updates we will be able to see if there are any waiting for us and the one that will probably improve the reader like no other solution has been able to do.
