Fingerprint reader sucks when wet - Samsung Galaxy S9+ Questions & Answers

Anyone else come from another phone such as the LG v20? I noticed the fingerprint reader on the LG v20 was much better when wet. At least with the lgv20 I could unlock my phone but with this phone it does not respond at all forcing me to use the power button and my unlock pattern.
Even the smallest amount of water or wet finger makes it not respond.

Yes wet fingers and also cold weather seem to affect fingerprint readers on lots of devices. Usually I can rub my finger back and forth on my shirt for a while to get the friction to sufficiently dry it.

Right. Little wet and it doesn't work.Not big of a deal for me though.

My LG V20 would work when wet. The Samsung doesn't even want to work even after I seemed to have dried my finger. It pretty much wants nothing to do with a rainy day.

Capacitive screen works with stylus-like objects?

I've discovered that my Optimus One screen responds to pens, pen lids, fingernails and other random objects. This makes no sense to me as doesn't a capacitive screen need a conductor such as human finger to operate. Or is LG just being dodgy?

hammers fix everything. sometimes permanently.
I got similar results from a homemade stylus (using a metal pen holding a saltwater-wetted tiny piece of sponge wrapped in a piece of a thin grocery store style plastic bag) and a cheap commercial stylus with conductive rubber at the end.
I thought that something was wrong with the homemade since I had to press hard to get it to work and it wouldn't slide well, but the commercial model has the same problems.
Also had things like wet towel activate the screen, but my woman complains that the screen doesn't respond to fingernails (not mine or hers) and she prefers the older resistive touchscreen type.
So it doesnt work with anyone else's fingernail either?
I know from the LG GT540 device (i have had that thing before my P500) you can use
both finger and finger nails - but its nothing for me, sometimes the display doesnt responds correctly.

Wet type screen protectors and the Note

I have long been a fan of the wet application screen protectors (Im sure theres a more official name for them). I like the grippier feel, nearly impossible to jack up installation, and ability to remove and re-apply if it's not straight or starts to peel up. I have used them for years now and loathe the thought of dry stick ons. But it seems if you use your stylus alot then you will want to avoid these as it causes the protector to bunch up and cause what seems like dots all over the main part of the screen. I discovered this because of that damn addicting game called Drawl Something that has me using my stylus so often. The good side is you can just peel, wet, re-apply. But this gets old. I have a replacement on its way just to eliminate any chance of this being a fluke. I plan on following the rules to the letter this time and apply it and apply minimal use and touch for a full 24-48 hours to see if this makes a difference.
Has anyone else encountered this on the Note or other stylus device?
Yes I have also ran into this issue while it's slightly annoying I also just fix it. I also noticed it only happens when you push fairly hard though.
I've got the wet-application Zagg on mine, and I left it alone for 2 days afterward. I haven't had any problems, although I haven't needed to press very hard with the S-Pen either. I don't really like the "stickiness" of the Zagg, though. I'm afraid of what it's going to do to the pen nub in the long run.
It does leave little tracks/trails in the screen protector, but I can't see them when the display is on and they seem to slowly fade over time.
I don't like how it slightly takes away some of the screen clarity, but you just can't beat free lifetime replacements at Best Buy.

Beware the low-friction hazard

Hey guys. Just thought I'd give you a headsup here.
I've had a bunch of phones (listed in my signature), but I have never encountered this before.
The other day as I was gaming I kept bumping my hand into my phone over and over. This has never happened before, despite that I normally put it on the far corner of the mouse surface to have it readily accessible. I didn't think any of it first and just moved it up, thinking that maybe I accidentally moved the surface or such, causing the phone to move.
Then in some downtime in the gaming I looked down and realized the phone was moving. My god! There was practically zero friction! My phone was just gently gliding around the mouse surface, lolygaging about. I had a little fun with it, poking the phone to make it slide a different direction and making my cat freak out with it.
I then put it to the side on the table, thinking that my hardshell mouse surface was probably so low friction that it made the phone slide around. But the same thing happened on my wooden desk. It kept sliding around. Then I turned it over with the display upwards, and it was fine.
This morning same thing happened, and it actuall slid off the edge of my kitchen counter (marble) and into the floor! The phone is fine, by some kind of miracle, but I was surprised it managed to pick up enough speed to not get stuck on the edge of the counter. I tried pouring some water on the counter to see if it was leaning, but nope. Flat on both according to the water and a spirit level.
My only conclusion is that the phone is so flat all around, including bezels, that it creates a small air bubble underneith it, which it then slides on. The feeling is that of an air cushion as well.
I realize most people probably dont put it display down, but if you do, be aware of this. My phone almost jumped to its death by it, surviving only by a guardian angel. I thought about it and decided it was a big enough risk to give people the headsup.
Stay safe G2'rs!

Good to know. Where I am, they only sell cases for QuickWindow (last I checked). I bought one, but it is taking a while to get used to holding the phone when talking since I can't wrap my fingers around the phone.
I was considering taking it off, but that notion is no longer in my head thanks to your post. BTW, you should post some vid on messing with the cat!
Hah, I just might. She's like.. "Oh, looks like fun", pokes it a bit, notices how it doesn't act as expected and is all like "BLAARGH" smashing it around and trying to kill it. xD
The screen is very silky, compared to my S3, Atrix, Kindle and my friends HTC 8S.

So what you're saying is glass is slippery? In other news the sun will set in the west tonight. Just kidding, but I wouldn't ever put my phone face down without some type of case to keep the glass from contacting anything bad. The Nexus 4 was extremely slippery, the way LG is making curved edges on the screens doesn't help in that regard.
Well, I've learnt to put mine screen down to protect it from things falling on it. The nature of my job means things may well fall on it. I use a screen protector film anyways.
And yes, glass can be slippery but doesn't have to be. None of my other phones have had this kind of behavior, probably due to them having a slight lift from the frame, keeping the glass off the actual surface.
Regardless, for some its a non-issue, but for those that it might affect, I thought I'd share.
Hoverboards are next. I can feel it.

This is a good point. I usually flip my phone screen down at night so the notifications LED isn't lighting up the room. Needless to say, my dog wasn't very amused when the phone slid off the nightstand and woke her up.

So I'm not alone! Lets hope someone saves a screen at least.
thanks for the headsup, on low friction surfaces things slide.
You check if you need to level your furniture so gravity doesnt make things slide
a case would help as well
Pretty common occurence also on the shiny plastic Samsung devices Even iPhones suffer from it.
Again, it's most likely due to the curved glass edge of the LG screen. I prefer the curved glass, and my best suggestion to those that need to put their phone face down due to work hazards should probably put a case on the phone. If heavy things have a chance of falling on it, it's probably a good idea the phone is either in a case or in your pocket. Just friendly advice so please don't take it as otherwise.
I had the GNex before so wasnt an issue...but day 1 with the phone. Put it face down on the counter top like I had always done before and got in the shower. My wife comes in and all the sudden.....BAM! My phone hits the ground. (thankfully on the mat!) She said she saw it kinda "gliding" towards the edge. Low and behold, this thing almost floats face down on any slick surface. I almost never put it face down anymore...lesson learned.

Fingerprint working with case fix

Soi figured out a very idiot proof way of making the fingerprint scanner work with cases.all you have to do is take a piece of tinfoil and run it under the back cover and have the price touch the side rail while also slightly touching the chrome piece on the home button. Now this works with and without a case and makes the finger print scanner surprisingly more acurate as it makes for a better ground. I'll post pictures after I get my replacement v10
I found that while using a case, if I move my finger tip slightly above the top of the scanner it works every time.

Screen Protectors

Anyone recommend a screen protector which actually has the pin hole at top and cover full screen.
As the ones about i see, don't even cover all the screen, leaving gaps at both top and bottom
Well, I found one absolutely perfect on amazon after reading numerous reviews on numerous screen protectors.
You get 3 in a pack, comes with usual wipes and also some glue for the edges, which really is not required at all.
Not a bubble anywhere, simply wiped with wet wipe and then dry, lined up camera dead centre and gently placed it,the screen did the rest and see the air bubble disappear, few more light presses to make sure and its bang on.
I am ocd and can say this tempered glass screen protector is absolutely spot on, covers all screen and hole for camera.
I also for first time ever did fingerprint on lock screen, didn't back up neither as i ain't letting samsung have my private info.
Took approx a minute to setup so you get full print, and on every single test approx 30 test now, it unlocked straightaway, soon as i touched screen.
https://www.amazon.co.uk/dp/B083P4D4HH/ref=cfb_at_prodpg
UPDATE:- the glue or liquid that comes with it, i decided to use also, as it got the better of me haha.
The edges there are a slight gap and I mean tiny, so have this liquid a go.
I poured it into a cap and used the little brush that comes in kit.
I did bottom first to test, brushed it on edge and it filled that gap.
Wipe with wet wipe and dry and pressed on glass to make sure it made contact and filled which it did.
I proceeded to do this on other 3 sides.
Dont worry about any going on the glass itself.
Simply use small sponge and soapy water to wipe of and then dry.
The glass can not be seen at all now, I forget I have one on, it is that good.

Maybe due to Pixel 4a?

well on amazon it is CAD$500 tax included, pixel 4a is CAD$541 after tax, aside from the better camera processing on pixel which i personally dont care much, i dont see a reason why should i go for pixel instead of this amazing mid tier phone!
I really dig the large screen on here
Still love my A71
Really surprised that this phone is not more popular! The camera is good for being a mid-range phone and price is definitely fair.
Anyways I am using https://www.amazon.ca/dp/B0852YB79R?ref=ppx_pop_mob_ap_share
It's extremely clear, doesn't attract fingerprints, and comes with a fitment frame to make it really easy to get it applied perfectly.
Fingerprint sensor works perfectly as well.

Sorry I will have to leave it for others to answer, but you can try a search for the same ASIN on the local Amazon site.
