    Take some hand wash and clean those fingers...
    Dry them with a soft towel...
    Re-register the fingerprints if needed... [​IMG]

    someone is not so idiot to ask this question without cleaning his fingers. u r a stupid enough to think that u r the only one intelligent guy here. dont put foolish suggestions to someone u didnt even know.
    . what i have written is that even after proper cleaning both the fingers and and scanner, it is showing the finer print scanner is dirty. the phone is not showing a feedback which i was getting two years before.

    He told you to register the fingerprint again after cleaning.
    Which means, delete what is there now and register again.

    And, do you have lots of scratches on the sensor?

    re registered it already. the reponse is okay, bt not like what it was getting two years before. i cant find any visible scratches in the sensor. still sometimes it shows the finger print scanner is dirty.

    Post a photo of your scanner. Make sure to take the photo under good lighting conditions.

    There are few things to consider...
    1. As you and I and everyone else... Electronics age as well... So as you don't expect same energy from someone when they age... You should consider something similar for your electronics too...
    2. We are not psychics... So it may look stupid to you... But those suggestions do help...
    3. Again... We are not psychics... And so we can't tell you if there is any physical damage to the sensor... So it you feel that the phone is not acting like it used to... You can always get it checked by a professional...

    I have just encountered a problem with the fingerprint sensor it was working just fine up until now. I have washed my hands, cleaned the sensor area, I can not add any new fingerprints because I get an error message there. it was working just fine like I said; I turned phone on and off several times.

    Dial *#808# then swipe left to debugging section >>choose fingerprint>>Select quality test>>Then place your finger in the scanner multiple times to check the scanner quality if it shows below 30 then it will be hardware issue you need to replace it
