Fingerprint sensor lock question - Samsung Galaxy Z Fold 2 Questions & Answers

So on a number of occasions I've picked my phone up from the table and when trying to unlock it it will say too many attempts have been made and wait 30 seconds. It's happened when bringing it it out of my pocket too but that seems more plausible if fumbling around with it and hitting the sensor too much but when sitting untouched it's something wrong with the sensor, settings, something. Anyone else? Ideas?

[Q] is my Xoom touch screen problem software or hardware?

I have had my xoom for about 6 months now and this problem has been with it since i got it...
Sometimes when i push the power button on the back to wake it up and start touching the screen it doesn't respond or barely responds, i have made sure my thumb is not touching the edge or anything... to make it work i have to hit the power button to make it sleep and hit it again to wake it up and it will work fine.
This problem is pre and post ics.
I'm not really sure what to do or if it is even software or hardware.
do any of you guys know what is causing this?

yes i saw this thread in my research but my concern is why would it work after i put it to sleep and wake it back up upon unresponsiveness?
If this was the case wouldn't putting it to sleep and waking it back up be useless, and i dont want to do anything that will void my warranty.

Sometimes when it is busy redrawing a screen (intensive) it is temporarily unresponsive until it's done. How long is it unresponsive to touch? If it will not respond for more than 30 seconds (I just pulled that out of my head, btw) I would think there's another issue.
It does it until i put it to sleep and wake it back up

Reading this over again, I'll bet it's a hardware issue, because 1) it's been a problem since day one, and 2) you've obviously updated your software, so any glitch caused by a bad install or an app incompatibility can probably be ruled out. Are you still under warranty? this sounds like something that could be/should be fixed.

Yeah i was just really hoping i wouldnt have to send it in under warranty because i know they will just send me a new refurb and be done with it ... then i will have to get a new screen protector and recustomize and be without a xoom for a couple of weeks

My Xoom did things like this, yet my foam fix made it end completely. Left the foam in there until I sent it in for the 4G upgrade.
I also had a problem with my XOOM screen. It was a headache for me and found a solutions today.
You should check MOTOASK (under XOOM). It was a new post and really helpful.

Press Unlock / Phone goes right back to sleep.

I've got a problem. Same problem I had on my G2 and I ended up getting rid of the G2.
For some strange reason at times when I press the button on the back to unlock/wake the phone the screen comes on and it goes RIGHT BACK to sleep.
At first it seemed like it was when my hand is touching the top of the phone but this morning I couldn't duplicate it on command.
Any clue whats happening?
I know this isn't any help to you, but I am seeing the same behavior. It took me 5 minutes to get the phone to unlock last night. If anyone has any ideas on this please help! Thank you in advance.

No it can be anytime. Usually if a finger is on the top of the phone but not always there and not every time it there.
Its weird.
The only thing that I can think of is the feature they use with the sensors next to the camera on the front. If your phone is in your pocket and the power button is pressed the screen will shut back off. You can test it by holding your hand over the proximity next to the camera. Then press power.
I know I mess up when I disconnect my phone from the power cord in the morning. The phone's screen automatically comes on when you unplug it, but I have a habit of trying to turn the screen on myself. What happens is that the phone automatically turns the screen on, and my actions immediately turn it off again.
I realize this probably isn't the same issue that some of you are facing, but it does annoy me!

Having problems with fingerprint sensor

Sometimes the sensor doesn't read my fingerprint for 8-10 times. Just keeps vibrating. I need to hold and press my finger dead centre to unlock. Is that how it actually works? Although sometimes it unlocks even just a partial touch. Also sometimes it doesn't respond at all. Is it a hardware problem?

maybe you set up your finger wrongly. try setting it up again. my fingerprint sensor works 99% of the times from the first time.

Yes maybe you did a faulty first setup. Set it up again but very careful this time.

I have deleted and setup the fingerprint multiple times. Each time it works for one or two days flawlessly. Then starts giving problems. Especially when running music player, it'll will never read. Well, I think I'll take it to the service center when I have time as the service center is in a different city.

I didn't get to go to the service centre. But i resolved the problem. I just added one more fingerprint of a different finger and now it works all the time. And is fast too. Don't know what that's got to do with that.

I made a setup for both left 'n right fingers too, because i've noticed from 1st day that when i was using the finger used in the setup there was no problems unlocking phone, meanwhile when i was tryin' to unlock with the other one my phone was just keep vibrating as yours. To me this is not a defect, but a clear sign of an even more accuracy placed inside this sensor. Think about it; your left fingerprint isn't the same of the right, because it just CAN'T be equal to the right one! So even if some line could match the other finger, the sensor detects a difference between one and the other and avoid the unlock. I registered my 2nd finger happy after that i thought this
Try to register the same finger twice with evwry different agnle. It will work almost ?% times
man i'm experiencing this too! but the difference is our phone. mine is honor 10 but like i've said i'm experiencing the exact same issue!! tried to do full reset still not working. i even try to register my first fingerprint data but no result. strangely, when my phone is off, and i tried to use the fingerprint, my phone was woke up! i do not understand what kind of bug is this but hopefully as the time goes it will resolved itself:angel:

Before the solution it'd be useful to know if this is an hardware issue or software one. Can you tell more about? Problems began after some drop to the floor or normally from one day to the next one? Stock or custom ROM?

P30 fingerprint picture showing up often

When my P30 is placed on the table (I don't notice when in my pocket, duh ) it lights up the "Place finger here" in the bottom.
Does anyone have an idea why that happens?
It's not like the table is moving or anything to trigger a read, so why is it showing?
Could it result in burn-in?
I have same problem, it could result in burning, but i have no idea why it shows up
It is annoying! I've turned it off in favor of a PIN to prevent burn-in
I wrote and email to Huawei and the replied rhat IT shouldnt result in burn-in.
And if I didn't want to risk it, I could turnering it off.
Not really a valid answer...

I'm surprised their IT is not aware of the latest OTA from last night, which is version 9.1.0.124(C431E3R2P2) and fixed the problem. The annoying fingerprint symbol no longer randomly appears but only if I move my phone (and in the pocket it would not show as the proximity sensor prevents that from happening, which I have tested).

I've kept it on. Normally I'm not the kind of guy who uses one, but this was placed on very well I still find the screen to be excellent, it does not bother me. Have you immediately pulled yours off or can you describe a before/after experience?

Is that the standard P30 you have on .124? My P30 is on .113.
I have this issue too, the symbol shows up several times a minute. I have seen others mention elsewhere that this could well be a hardware issue?
I'd just assumed this was a software issue but if it is hardware then it may be time to return it?

Yes, it's standard version... After I bought it (first day), phone was updated with this version ...
After I switch off the phone (and put it on the table), symbol shows up for a few seconds, then disappear until I move the phone ..
Maybe you should try first with .124 version .. ?
Hi
My p30 is on 115 update and still has the same problem
Anyone try without or with a different screen protector?
I have found some kind of solution, but by some reason it does not work all the time. Settings- Smart assistance- Shortcuts & gestures - wake screen - Double-tap screen to wake. Activate that option and reboot the device.
But as I can see, that light might be used as some kind of notification light since it blinks when there is something, like e-mail, message and other things that need attention. When there is no internet connection it is not blinking until you move it.
All of the above are just my personal observations and I don't insist that they are 100% correct.
Having this act as a notification indicator isn't a bad theory, although the frequency of it appearing seems wrong for that kind of use.
Personally, I'm bummed at the lack of notification light, something I had been relying on for years with all my previous phones. I might end up taking advantage of the OLED screen and just make it keep the screen on instead.
My phone updated from 111 to 121 today (I guess we have different build numbers in North America), I still see it flashing from time to time while it sits on my desk.
Update: I tried with a tempered glass screen protector and now it doesn't show up unannounced anymore.
I think it is an issue with sensitivity of the screen.

Camera not rotating view and motor stuck half way

Hi there!
Since ASUS isn't responding to my question, I might as well try here.
My brand new ZS630KL which I've had for almost a week now acted strange at some time during the first 24 hours of use.
When I try the ASUS camera app, loading the camera takes way longer than it did the first few hours, and when changing from back mode to front mode, I see myself up side down. Also there's a message on the bottom of the screen telling me the camera can't turn (flip) the image.
The camera module doesn't return to normal position if I try to drop the phone controlled (like you see every other tester on YouTube does it), but it did so the first few hours.
If I try to go back from front view to back view again in the app the camera stops mid-way, just below 90 degrees, and if I exit the camera app from there, the module tries to move back to normal position, but tries to go further than it should and you can hear the screams from the gears as they skip and skip and skip...
I do think this has to do with the gyroscope in either the phone or the one in the camera module itself, and have asked ASUS if there is some way to check if the gyroscopes are working or atleast try to re-push the firmware onto the camera module.
Using other camera apps like Snapchat or Facebooks camera functions work like it should, even though they all show the same system message telling the image can't be turned, their software flips it either way, and also their preview from the camera opens instantly like it should.
Anyone that has any idea what this could be are more than welcome to reply. Using it as my phone at work, so resetting the phone is an option if that could recalibrate the sensors, but I see that as a last resort kind of thing since the phone is brand spanking new.
Thank you.
Ouch.... does not sound good at all! I would return it as fast as I could and either risk getting a NEW replacement, or get my money back.
seems faulty piece, return it
Thank you both for your reply. I've contacted the webstore where I bought it and explained it to them.
Thing is that they've out of stock and doesn't get new shipment until 17th of July, so I have to wait a while either way. Sending it in for repair is out of the picture since it started acting like this shortly after first usage.
Ideally I would like a new unit, transfer everything from this phone to the new and then return the first phone. Transferring data from one phone to anther and then back to a new ZF6 again seems like such a hassle.
I understand your hesitation, but in case you are in Europe, I truly suggest that you send in the phone now before the shop gives you some trouble. You will have 14 days to return it without giving reasons.

Sure, I do get that. I'll see what the store says. They have to replace it anyhow, so question is how if they are out of stock.. ?
I'm experiencing the exact same behaviour with the flip camera as described in OP.
 @Bjarte, did you ever resolve the issue or did you have the phone replaced?

I got it replaced. When ever this happens on the replacement it always works to just tap the flip button twice like Asus intended. Normally it's just the software that gets confused, especially when you switch from the stock camera and 3rd party apps it seems. But I can live with that.
The problem like I had on my first device was that the normal "fix" never worked.
Then I'm afraid I should need a replacement too, because tapping the flip button does not work for me at all.
Get your money back and stay away from this piece of ****!
I have never seen a phone with so many problems before people can even really get it in their hands.
It's up to you.
Issue caused by cover case
Turns out my third party cover case is blocking the proximity sensor, causing the retraction of the camera to malfunction.
https://zentalk.asus.com/en/discuss...-message-is-shown-camera-cannot-flip-pls-help
Several cases concerning this have been resolved due to the root cause being that a cover used was covering the proximity sensor located in the front. Even a slight cover of that sensor may cause this - as it is intentional design that when the proximity is being covered the camera should stop its rotation.
