Yes. Ever since Samsung went to the in screen fingerprint sensor it is slow and unreliable. Many on here insist there is no problem. Maybe they never used a real honest to gosh sensor like on the Note 9 or iPhone touchid. I've tried every trick and setting fix I've seen published but for me it still stinks. I'm lucky if it works two out of three tries. It forces me to slow down and concentrate on what should be an automatic reflexive action. Maybe I have bad fingerprints but my Note 9 sensor still works instantly everytime, so I refuse to just say it's me.
I agree in my experience... TouchID is probably the most consistent biometric I've experienced on a phone... I don't remember when it didn't work. Capacitive rocks and no real issues with it except you had to make space for a hole either at below the screen or on the back... too bad they didn't think of putting them on the side of metal frame sooner.
I had a "real" sensor with the Note 8 and now if I had to look back and think about how well it worked for the last 3 years, I'd be surprised if it has a total success rate of over 25%. Tried all the tricks of multiple registers and even trying to do stuff like double-tap or triple-tap on the sensor to get it to read and count it as one-attempt. In the end I went with Iris unlock over most of those 3 years. That's why when I heard and read about the in-glass FPS the past couple years, I was not looking forward to anything much better.
But since day one, I have been pleasantly surprised how well it has worked on the N20U... and with TPU screen protector on top of that! For the last three years, I'd press on the sensor on my Note 8 and wonder every time if it's gonna read it.:-\ I've now been able to use my phone and not have that pop in my mind when I do. It's not perfect... I'd say failure rate easily less than 10% but I think it's because of trying to find the sensore area when screen black... it'll be good for future owners with 2nd gen sensor area being bigger.
Is it just you then?? I don't think so.. it just seems Samsung sensors don't work as well "for everyone" like other types out there like TouchID. But compared to past phones on past Samsung phone sections here... this is probably the quietest it's been as far as tallking about the FPS. This variation seems to be working the best so far for more people.
With that said, I wouldn't have minded if they went with capacitive on the side like they did with the smaller Note 20 but I'm happy with the FPS on the N20U.
