Fingerprint scanner question - Samsung Galaxy A50 Questions & Answers

How is the speed/accuracy of the fingerprint scanner after the recent updates? Its said to be slow and unreliable at launch time.
Is it now as good or close to the usual capacitative scanners?

Yes it is slow(even after update) especially when you try to unlock when the screen is off (takes 1 second), and on always on display it takes 0.5-0.8 s, sometimes it doesn't recognuze fingerprint. So compared to the usual fingerprint scanner, it's very slow, though it can be improved via updates

Samsung released another update earlier today that was focussed on the fingerprint reader and it has certainly improved the performance. Comparatively, it now takes half the time it took with the original firmware, though it is still slower than a capacitive reader. More importantly, the accuracy has improved a lot compared to the original firmware and it rarely fails, as long as the finger lands on the right spot.

A few minor issues - any suggestions?

After buying my P8000 right at the start of August from Everbuying.net, I finally received it yesterday. And I have to say - the vast majority of features/functions of this phone are AMAZING, especially when considering the 160 USD price tag
However, I've noticed a few things:
1. The screen seems a tiny bit unresponsive at times. It also doesn't seem to scroll fluidly when my finger is on the screen; yet, weirdly, if I "flick" the screen to scroll quickly, it appears to transition smoothly.
2. The battery life seems to vary between incredible, and sub-par. Maybe a battery-reading issue?
3. I'm in Australia, so the network bands checked out fine. However, I've noticed that sometimes the 3G simply cuts out, even when I have full signal. When on WiFi though, I get great transfer speeds.
4. The fingerprint reader isn't that accurate.
5. There are 3 dead pixels or specks of dust that I can see (just) on the screen. I remember reading a review saying that they experienced the same issue. Is this common, and could I return my device for a replacement?
Has anyone else experienced these issues? Would Elephone perhaps release a patch that may fix them (other than the dead pixels)? Gotta say - if these issues were removed in future phones, like the Vowney, I think I'll be a customer for life!

Havn't noticed this behaviour at all, did you (by mistake) activate any sort of Power saving mode?

I have amazing battery time all the way Install GSam Battery monitor (or similar) to check if you have any unwanted wake-locks

Dunno
4. The fingerprint reader isn't that accurate.
Mine unlocks the phone super quickly with an accurancy of about 80% the first time
5. There are 3 dead pixels or specks of dust that I can see (just) on the screen. I remember reading a review saying that they experienced the same issue. Is this common, and could I return my device for a replacement?
Didn't hear about this, check with your provider of the phone if its very annoying
Best tips of ALL. Before you go any further you should upgrade to latest firmware. Elephone themself have already released 3 upgrades which solves a lot of issues! So go for latest STOCK or try the excellent ERAGON ROM

I had "Intelligent power saving standby" mode activated, as it was on when I first turned on the phone, but I don't think that influences non-standby?
Even after turning it off, the phone still takes about 1 second to wake from standby upon pressing the on button.

Mine takes a solid second, and only seems to work about 50% of the time. Maybe I'm doing something wrong.

I've tried updating but it says there are no new updates available. How do I know if my phone's on the latest version; and if it's not, how can I update?
Thanks for your reply!

Ahh, you mean when screen is off and locked and you press the power button?
Takes about 1 second for me as well before i can get into phone
I'll give that a go, thanks

Might help with newer firmware (if you dont have already)

what about battery life on 4g? i have p6000pro and battery goes down crazy fast when 4g is enabled... but on 3g its quite allright...
For the fingerprint sensor, be sure to register as many finger positions as you can. When you register a finger, you have to repeat 15 times. or so. When you do that, you can slightly move the finger up and down and to the sides each time, so you register a bigger surface overall. The first time I registered the fingerprints I didn't do it this way and the sensor didn't seem to work very well, but after I did it the way I'm telling you, success rate improved a lot, and now it's more on the 90% to 100% range.

[Tip] Make the fingerprint scanner work better

Hello I would like to share something I found out about the fingerprint scanner, that worked for me and hopefully for you as well.
When I received my Elephone P8000 I was disappointed that the fingerprint scanner didn't work as well as I hoped (about 50% success rate).
First I thought it was the Phone, but actually it was my own fault. and now it works 99% of the time
The wrong way: when adding a new fingerprint, I placed my finger at the exact same spot every time while configuring.
The good way: hold the phone like you normally would when unlocking the phone, and place your finger at slightly different places on the scanner when configuring (do not center your finger at the exact same spot).
I hope this helps.
That's the way I've done it since I bought the phone and my success rate when using the fingerprint scanner must be around 90% (no kidding).

Same here. Actually, I think my success rate on the fingerprint scanner is higher than 90%.
I'm getting good results from this
Depends on fingers skin too. Scanner dosn't recognise fingers a lot when having dry skin(washed hands a lot in a day) and had normal skin when entering prints.
Thanks for sharing, i getting 90% success rate with this method.

Fingerprint scanner problems

Are the Tab S fingerprint scanners known to get worse with time? When my T800 was new, my success rate with the fingerprint scanner was something like 3 out of 4 times (so, it wasn't a great scanner to begin with), but now it got worse than 1 out of 10.

Fingerprint sensor useless

I have had this phone since September and came from Huawei P30 Pro, before that Honor V10, Huawei P20 which had fast fingerprint sensor and worked 99% of the time first time .
I cannot believe how bad this sensor is in real use, unlock success rate is about 5% no matter how many times I delete and Reregistered all fingers.
I scan my prints and test in the setup and they are acknowledged correctly but once I start using for real to unlock the phone or approve stuff it rarely works.
I have tried all kinds of angles and strengths of press but it's useless.
Running the beta in hope of improvement but it's still useless.
Did I get a bad unit here or is Samsung just totally crap with fingerprint sensors?

After you've registered your fingerprints.... re-register them to improve the accuracy of the scanner. Also, if you find it sluggish, reduce the animations in the settings...
Sent from my [device_name] using XDA-Developers Legacy app
I am reregistering prints to try and improve and after every update hoping something is better.
As said when setting up and checking it is fine but when I have to use for example with 2FA app to approve a log in it just fails "fingerprint not recognised" before eventually going to pin.
Will try the animation setting and see if that helps.

for a while, the Note10+ fingerprint reader had a terrible success rate, no matter what "hacks" i used to try to make it better (i.e. multiple fingers, the "test/learning" hack, etc.) — loads of "make sure you cover the entire sensor" and "no match found" etc.
this tip might be crazy, but it does work: MOISTURIZE LIGHTLY.
100% serious.
my right thumb was not able to unlock my Note while i was working at my desk. super frustrating. looked at my hands, thought they were looking dry, so i put a dab of glycerin hand cream on and BANG: every single damn time now, regardless of whether my thumb is vertical or sideways.
I got my Note 10+ today and have spend a long time setting it up. Once I registered my prints I had not issues (unless I didn't press firmly enough on the screen). It's been fine for me thus far.
You shouldn't compare ultrasonic fingerprint sensors that are in their early stages with optical ones that have been out there for years. Ultrasonic is much more secure. And saying that success rate is only 5% means that you either have a defective unit or need to change the way you use it. I have a success rare of no less that 90%... not as accurate and quick as my old note 8 with its optical sensor but I got used to it
I've had no issues with the fingerprint sensor, before or after the update.

heh yeah classic S10+ fingerprint reader from Samsung. I also found the same "you need to lick your finger first. Yeah, it's not a joke. " :laugh:
yep lick your finger first does actually work, if you have dry hands the scanner is mostly trash, use moisturiser/lick/damp your finger and it will work near 100% reliability. basically if you don't have clammy hands it will likely be hit and miss.
actually found myself in bars using the condensation on my drinks to help me unlock the phone, it seems an odd thing but it seems moisture in your skin is a massive deciding factor on it working.

Question Follow up review of the Pixel 6 Pro

Do you agree with his retake?

I do
Auto brightness never worked well on any of my Samsung's, uses excessive battery pi$$es off my retinas, so i always use manual control. It's not just a Pixel thing
Personally I rather see a review where the reviewer finds flaws and pick away at them; it shows candor. The endless mainstream reviews of Samsung flagship duds that give them glowing reviews to boost sales are so old and predictable. Reddit gives better reviews
Updates break things. Upgrades destroy worlds.
Leave it be unless you see them working miracles for other users after a couple months. Trust more what individual users and small fry reviewers say than CNET, Tom's Guide, Phonearena, etc.
Take what you got, optimize it, and find work arounds rather than constantly updating and upgrading it. Every time you update and especially upgrades you change the playing field and you can end up starting the optimization/work around process all over again. Like a reoccurring nightmare. Who wants a phone with an identity crisis that's constantly morphing into variants you have no control over?
I want a fast, stable, reliable platform that fulfills its mission. I have no desire to be an unpaid perpetual bataware tester for something I paid big bucks for!
You may not agree with what I just stated. I don't respond to sales/scare hype. I want to see rubber biting into the bloody asphalt not just a cloud of smoke and noise.
Case in point is this N10+ in my hand still running extremely well on Pie. Current load will be 2 yo this June. It's fast, stable with minimal maintenance and bug free. I spend very little time troubleshooting it now. Security is not an issue.
It does exactly what it should be doing, working.
I'm currently looking for another phone as the signal is so poor on this chipset and Google has locked it down so I can't get 5G or Volte even though my network is supported they won't unlock it
I think he needs to RMA his phone, because I did that as well. Amazing experience after it!!
Interesting, i have a Pixel 6 Pro, my wife has a Pixel 6 and my best mate has a Pixel 6 Pro and apart from the fingerprint sensor being a bit off to start with i cant say we have had any problems since the phone came out.
I've never known adaptive brightness work particulaly well on any phone i have owned to be honest so thats just the norm for me.
I agree with his take.
Auto-brightness has been abysmal on this phone since the beginning. It really shouldn't be, not when they're employing two ambient light sensors. It's especially painful because I use the device in dark environments very often (have a baby, use it to play sleeps sounds to him while he falls asleep) and it never assesses the brightness correctly. The torch thing is also a massive irritation, since it ramps the display brightness up to max in a pitch dark setting, then takes an age to eventually move down to a more acceptable brightness, but not without blinding you first.
I've never had this problem with any Samsung device employing dual ambient brightness sensors; on the contrary, I've always found the brightness settings to be close to perfect on these devices, even the ones where the front sensor shifted under the screen.
Signal is a significant weakness on this phone as well. Whenever I pop to the stores, I regularly find myself without signal when inside the store. I have to literally walk out and walk back in to restore some signal in case I need to call my wife or message her. I can honestly say that weak signal is not the biggest issue to me, it's that is just about disappears in places I have had no issue with other devices. And it's also something that seems to be a problem for me with Pixels, at least on my carrier. This is just the worst I've experienced by a long shot and has me pausing for safety reasons.
The fingerprint reader is not great, but it's much less terrible than it was at the beginning. I've not been as impressed with the cameras as I thought I would
There are still weird bugs (Google Assistant randomly pops up from time to time; changing wallpapers causes the quick settings toggles to disappear until you fully open the notification panel; the April update randomly reset all my custom notification tones; app search sporadically stops working; lift to wake and tap to wake still way too sensitive) and Google has actually regressed in some UX aspects (removing the vibrate icon from the main status bar; the internet tile; the choice of UX around the always on display; etc) compared to even Android 11.
Overall, this is still a great device, and fluidity of the experience is second to none. Too bad about the almost unbearable signal and effectively non-functional auto-brightness.

Adaptive brightness is close to perfect on the S22U. It can be implemented successfully with the right hardware.

thats why i said on any phone i have owned.
The voice to text is strangely broken on this phone. I see many people complain about it specifically on the 6, whereas all previous pixels had excellent voice text accuracy. I still use it primarily for messaging and just accept that people think I'm illiterate.
I'd agreed with the hardware issues. The antenna isn't as good as any of Qualcomm's recent stuff in signal and battery, and the fingerprint reader (which I'd probably rate as "fine" at this point) is still a notable dropoff from the one on the back of the phone.
But there's other complaints from that video that have never been a problem here. Wi-Fi Calling is the one that sticks out that's been great on my device.
