PSA - How to improve the recognition on the in-screen fingerprint sensor

[darrenk232]

Hi all,

I've read in various forums people having poor recognition of their fingerprints on the Mate 20 pro in-screen scanner and I too was suffering the same issue. Oddly, I found that over time, my right thumb (the finger I used the most) was being recognised more consistently. This then led me to believe that the system improves recognition the more you use it. So....

If you head into the "fingerprint ID" area under the security and privacy menu, there's a feature named "identify fingerprint". If you select that and repeatedly try each finger, as it recognises the finger, it begins improving immediately. I did this with 4 fingers and after about a minute of "training", my success rate for all fingers went from sub 30% to greater than 90%.

Hope this helps.

Darren

Thanks, I will give it a try. At first I found the fingerprint reader horribly picky and slow, but even after a couple of days I have adjusted and can open it nearly every time with the right press. Unlike some readers this thing seems to want to see your whole thumb, so a flat press is necessary, and so is somewhat accurate location of that press. And... You have to hold it for just that right amount of time... I still sometimes get several failures in a row for no apparent reason, but overall I am happy with it.
