Moto E4 XT1767 Fingerprint Scanner Lag

[skotseno]

I picked up this phone on my local craigslist late last week (at $15, I could not resist), unlocked it, and have been using it. When compared to my moto Z play, I have to hold the fingerprint scanner longer to turn the phone on or off which for some reason is very frustrating. I do not believe this is a hardware limitation as the fingerprint response is instant if I turn the device on to my lock screen and then touch the fingerprint scanner.

Does anyone know if it is possible to correct this? At the moment, I have to touch the scanner for ~1 second before it will turn on/off my phone. If it were possible to change this to ~0.5 seconds, I would be a happy camper.

Are you running stock software? If so, I'd try erasing and re learning your finger prints. I got an E4 for my daughter to use on WiFi - FP sensor is snappier and more accurate than my MZP. If that doesn't do it, I'd be inclined to think hardware issue.

Well here is the thing: when the phone is on the lock screen (screen turned on and asking for fingerprint or pattern/pin) the fingerprint sensor is instant and always accurate. The only time I am seeing lag is when I hold to turn the screen on (the screen is off but holding the fingerprint sensor turns it on) or off (phone is on and unlocked but holding the fingerprint sensor turns off the screen).

Can you confirm that your daughters phone has a faster response when turning on/off the screen?

i've read from a handful of reviews that the scanner is just simply not as fast as the MZP or even g5+. could be a limitation of the processor? i moved from a MZP to the e4, definitely a noticeable difference in speed.

Yep, the times I use it, it's normally from screen off condition, or from in use to lock/turn off screen.

I'll try to do a side by side tonight with my MZP

here's a link to a quick head-to-head video. What is apparent is that the other poster is indeed correct - MZP is slightly faster from touch to screen on, and touch to screen off. The difference is slightly more pronounced when waking than going to sleep. What isn't apparent from the video is the timing of the haptic feedback. On the MZP the vibration is triggered almost instantly at touch, with the bulk of the delay from touch to screen on happening after the vibration triggers. On the E4, the vibration occurs around the middle of the span from touch contact to screen on. This gives the impression in use, at least to me, of slightly more laggy sensor (on the E4) but slightly faster unlock times (on the E4).

Guess I don't have to be jealous of my kid's phone anymore. Was a cool experiment.
