Fingerprint sensor really bad?

[limone1]

Hi,

how is you fingerprint scanner doing?

My finger gets recogniczed like 1 out of 30 times.

Adding a fingerprint is painful enough, like after 5 minutes I am able to add it.

Hi @limone1, welcome to the community.

Here's some tips to improve your finger print recognition. 

• Dirt or moisture on your finger or the power key during the registration of your fingerprint can affect the sensor’s ability to later recognize your fingerprint. 
• Use a clean, dry cloth to wipe off any dirt or moisture from your finger and the power key before registering your fingerprint.
• Using the Fingerprint Manager, you can register a fingerprint up to five times to improve the recognition rate of the fingerprint sensor.  
• Make sure that you do not only register the center area of your fingerprint. Between each vibration of the power key during the registration process, move your finger slightly upwards, downwards and sideways to include a wider area of your fingerprint in the registration.
• The condition of your skin, such as cuts, dryness, or moisture may have an effect on the fingerprint recognition rate.
• Any activity that may affect the state of your skin, such as showering, cooking or exercise, can have an effect on the fingerprint recognition rate.
• Any dents and scratches on, or near, the fingerprint sensor in the power key may decrease the recognition rate of the fingerprint function.

You're saying this like I am a five year old who never had a smartphone in his hand.

My fingers are completely ok, I also let some friends test it.

The power key has no scratches or whatsoever, it's a brand new phone.

• You can also register the same finger multiple times for more accuracy.

looks like the same tip was posted twice besides, from what I've read that's going to slow down fingerprint recognition a bit.

The fingerprint scanner is usually very responsive. If you have completed all the steps and you are still experiencing the issue then I recommend you try it in safe mode to see if it is still poor. 

If it is the same in safe mode, then the last step would be a software repair using Xperia Companion.

If the software repair does not help, then I recommend you either contact your retailer or your Local support team for further assistance.

I find that by making sure your finger is pressing on the upper extreme of the sensor it works better. I do agree though that is very sensitive and could use some improvement. But for sure if I press towards the bottom of the sensor it does not work. Towards the top and all is OK. Since I have figured this out I have been much more successful of getting it to work nearly every time as expected. Of course a wet or sweaty fingertip is a no-no. All must be dry. Also I find that by using the  tip of my finger, as opposed to the larger flat part, that it works better. Even though I am right handed I hold the phone in my left hand and use my middle finger to unlock. YMMV
