I used a Huawei P10 for a while, which is a few years old, but has a great fingerprint sensor. It’s on the home button, you just touch it with your thump for a split second and it unlocks your phone / verifies your apps.
I now switched to the FP3, mainly ideological reasons, but also because the dual sim meant that I would be able to use this as my private and work phone in one device. Sadly I have to say that the fingerprint sensor is so bad, it is basically useless!
The position sucks. I have bigger hands than average, when I pull my phone out of my pocket, the tip of my indicator finger will naturally be 2cm below the sensor. So to unlock my phone with the sensor, I have to hold my phone in a different position then I would usually do, which is super inconvenient. I can’t imagine anyone who will have his finger naturually on the position of the sensor and I do not understand why it is not on a lower position!
The damn thing doesn’t work!
I use a lot of apps which can be unlocked via fingeprint (mainly banking/online payment) and fingerprint unlock would be super convenient, since I try to use extra secure passwords on these apps, which are very annoying to type in, every time I switch out of the app!
Whenever I try to unlock my phone via fingerprint or validate something with it, it will show me an error that it couldn’t regocnize the fingerprint, that I need to try again and that I may need to clean the sensor. The sensor is always clean. I wipe it every time I get the error, nothing changes. I used all possible fingerprint slots just to scan the same fingerprint over and over (I have 5 scans of the same indicator finger) and it still wont recognize the damn finger!
Back on my old phone I just swipe my thumb over the sensor and it worked, right now I flip over my phone and try to aim exactly for the right position, which works 20% of time. Most of the times it will block me after too many failed attemps and I am back to typing in my overly complicated password.
I don’t understand how this could have ever passed testing.
Edit: changed the title, in case this issue more individual than I first assumed.
