[Q] Can't unlock my DHD when the phone is laying flat on a table

Hi,
I got a DHD and for some reason I can't unlock my phone when its laying flat on a table.
I've recalibrated my sensors and still no change. The only way it unlocks is if I tilt it on an angle. This also affects games etc if its not on the correct angle.
(PS. This is the standard unlock slider on the DHD + not talking about the pattern unlock...)
Thanks in advance,
OGEZZY

cant unlock when slanted? you using pattern unlock or ??

Sorry I didn't explain it correctly.
I can't unlock the fone via the normal slider. This only occurs when the fone is flat on a table. If I put the fone on an angle or hold the fone in my hands I can pull the slider to unlock the fone without any problems.

This makes no sense whatsoever! The g-sensor has no effect on the lock screen... Have you checked the tasklist to see if there's any background apps which might be overriding screen input? I know Handcent can popup SMS notifications over the lockscreen... Maybe there's an app waiting for input, prompted by the orientation of the phone...
It's a long shot, though. Does it do the same on any other horizontal surface?

It has to do with how a touchscreen works. When you don't hold your phone in your hand and only use your finger to touch your screen it is less responsive. Mine does it too, it still works but i did notice it is less responsive.
Thats how capacitive touch screen works, they need a guiding ( electricity) true the body of your phone true your finger. It is less when not holding your phone.

That`s capactive touchscreen "issue". Holding phone in hand has better "ground" and touchscreen works better. Everyone has it

Have you tried without the charger connected?

Yes I have same thing...

I had that. Calibrated my phone and it was a little better. Then after a while it was fine didn't come back. Forgotten about it until I saw this thread.

Did you already try a factory reset?
It is always worth a try when dealing with any kind of computer problems
Another possibility may be that you have sweaty fingers or some kind of fluid on them that makes the touchscreen unresponsive.
If it still doesn't work, you should probably contact HTC about it. You may have got a bad device.

Fingerprint instant unlock without a HW button press first

I am wondering if anybody else has been annoyed by this:
On Samsung Galaxy S7 edge one had to first press a HW btton (home or power) and only then able to unlock using the fingerprint scanner.
On the S8 this is not so. Touching even for a moment the fingerprint scanner instantly unlocks the device!
I noticed that when the phone is in my pocket I would touch the fingerprint scanner inadvertently causing the phone to unlock.
If we look at the iris scanner:
One has to first press a HW button and then utilize this unlock option. But for fingerprint unlock, no...
I think this fingerprint scanner unlock procedure is solved immaturely by Samsung and would like to see if more agree.
Or am i missing an option somewhere? Comments/advises are welcome.

I prefer it that way, although I find it's in such a bad location that it isn't useable.

Hell no, the entire point is that it unlocks instantly. people dont want to be pressing other buttons first, taking extra time and effort dozens of times a day to unlock it. i cant see many people unlocking the thing by mistake by having their hand in their pocket!! It's hard enough to hit the sensor properly even when TRYING to! The fact it unlocks instantly is fantastic, i was impressed by how fast it is (when I manage to hit the scanner properly).

That's the thing. It's fast, really instant.. That's why a momentous touch in the pocket is quite possible to unlock the phone.
I understand why you like it. And agree is useful.
And may be if there was an option to choose instant unlock OR unlock following a screen on first (by a HW button) would have been nice.

Yeah they could add an option for that but i doubt enough people would want it for them to do it

I prefer it like this and the placement isn't bad at all either.

I was only able to unlock with fingerprint about 50% of the time.
I found out that after using a double tap gesture in Nova launcher to lock the screen, it required my pin to unlock. I disabled that gesture and now the fingerprint unlock works almost as well as it did on my Nexus 6P.

All phones with fingerprint sensors on the back will instantly unlock when you put your finger on the sensor. That is the whole point, to quickly and securely be able to log into your phone. For example the Nexus 5x/6p and Pixel phones all work this way. The Galaxy S6/S7 2-step method of pressing the home button and then waiting for the fingerprint to read was a somewhat wonky way of doing things that Samsung is moving on from.
I'm not sure what you mean by "I noticed that when the phone is in my pocket I would touch the fingerprint scanner inadvertently causing the phone to unlock." The phone will not unlock in your pocket with just any incidental touch on the fingerprint sensor. It has to be a registered fingerprint and your finger has to be placed squarely on the sensor. So unless every time you reach down into your pocket you are pressing your finger perfectly centered on the sensor, I find it hard to believe your phone is unlocking due to the fingerprint reader. There is an option called "Keep screen turned off" in Display settings. With this setting enabled, if the phone's proximity sensor recognizes it's in a bag or pocket, the screen will turn itself off after 5 seconds if the power or home button is accidentally pressed, so perhaps you should enable that.

I love this "feature" but yes you're right, it happened to me gazillion time to accidentally unlock the phone in my pocket. My "fix" to this issue is to have the back of the phone facing against my hand - problem solved, I can't touch the sensor that way.
Enjoy your new phone!

The fingerprint scanner works the way it's supposed to. Go buy another phone that has a real scanner & correctly placed (Like the nexus 6p) and test that, then come back.
OP is used to the crap samsung has pulled for many years, front bottom ugly enormous button acting as a scanner. Just look what they've done with the S8/+, Without the button, it's insanely beautiful. I've only owned a samsung within my work, i'd personally NEVER buy one. But the S8+ changed my mind. The position of the scanner isnt even a big problem. Although i'd like to see it in the middle like the 6p and all other correctly placed scanners. But i've got no problems reaching it.

I find the sensor on the S8+ to work very well. I had given up using the one on my Note7, since it failed to identify my fingerprint half the time. But on the S8+ it's much more accurate. And I like that it turns on and unlocks the phone with just a touch (like the Nexus 6P I had before).
I'm even getting used to the placement. Particularly with a case on the phone, the cutout of which helps identify the location by feel, it doesn't seem like a problem anymore.

Works great for me.
Phone is lock in pocket. Pull it out and put finger on sensor and it unlock to home screen..
Works as it should.
Iris scanner works like this if you pick the phone up from wireless charging.

It's really starting to grow on me, especially when Samsung Pay. I don't know how many times I pressed too hard on the Home /fingerprint sensor and ended up closing SP and starting over.

I had a S7 Edge Duos for a day and tried Nova for a short time. I set the double tap gesture and Nova told me about a workaround.
If I wanted it to unlock right away it would ask for a PIN everytime but if I let Nova set a black screen for 5 seconds and then lock itself it would unlock with the finger scanner.
Ontopic:
I totally love that the phone is unlocking this way now. I freaking hated that I had to press a button before the fingertip scanner would unlock the phone and it only lasted 24 hours with me.

Exactly the way I like it. Got used to it on my LG V20.

I hate it too!
I just bought a S9+ and I really hate this feature. I am CONSTANTLY accidentally unlocking my phone. The fingerprint scanner is fantastic in that I barely touch it and it unlocks. Perhaps I just need to delete all of my fingerprints except a pinkie or something weird, so maybe try that. At this point, I just had to turn off my fingerprints together because it was getting sooooo annoying, but I'll probably do the pinkie thing eventually because I loathe having to do a PIN.

I got massive fingers and constantly encounter this issue. Not everyone has fingers the size of rice puffs that accidental unlocks aren't an issue.

LED cover locks the phone

Hey, just got official Samsung LED cover which is real nice but what I don't like is having security set to lock the phone after 5 minutes I got the phone locked each time I close the lead. So I need to unlock it every time after.
Is there a way for the cover to use my settings? It looks like it acts just like power button which force locks the phone (and I do what to keep this behavior for the button).

Can't you just toggle off the "Lock instantly with power key"?

I guess you have to compromise. Set your auto lock to a shorter time.
I do think the LED case is awesome and the close/lock is not an issue to me. But I do see how it could be a problem to some.

I'm pretty sure there are separate settings for some accessories including the LED cover.
I'm sure I have seen some settings on my dad's S7 Edge and he uses the S-View flip cover with it. I will have to recheck his phone...

There's a LED pattern editor to it but nothing else I found so far.

Sorry off topic but still has to do with the led cover.
Anyone pair the led view case with the whitestone dome glass screen protector? Just want a simple yes they are compatible or no, it will lift the protector is fine. Thanks

LED cover no longer locks the phone

Hey Desperex, I had the same problem with my Note 9 but I found a setting that make the cover not lock the device anymore:
Settings -> Biometrics and Security -> Other security settings -> Device admin apps -> Google Pay. If Google Pay is on, the screen will be locked, if off, it won't.
Hope it works for you too!

Audible sound from camera module when locking and unlocking the device, anyone else?

The camera doesnt move but I can feel mechanical movement when I open and lock the phone. Anyone else experiencing this?

No sound or movement here when unlocking.
Do you have face unlock enabled somewhere? It might be preparing the camera to move for face unlock or something like that.

No I don't have it enabled and never have, there isnt any abnormal apps with access to the camera either..

Maybe the mechanism locks down a little tighter when the screen is locked seeing that it will not be used while the screen is off? Then, when you unlock the phone and the screen is turned on the mechanism gets ready for any movement that is needed by the end user?
I cannot wait until far more people have this in hand so that all these various questions can be addressed.

I actually tested this and think it might be correct. I forcefully flipped the camera up a bit when the phone was off, if you try to put it back into place the camera module will be in a pretty "loose" position. When locking/unlocking the phone it goes back to the firm "locked" position.

Yes, I think so too
When locking screen I can hear the motor giving one faint "click" as if it is "locking" in place. Seeing as it is a free-angle motor I guess they need to "lock it" somehow , as Ive actually tried holding it by the camera module and "flipping the phone" around - which actually works.. although not sure if that's recommended to do

Hi, i experience the same thing: there is a faint noise when locking and unlocking the phone screen. I guess this is normal, i have to put my ear near it to hear it.
When i received and unboxed it, the camera was loose. It was flipping freely. It was only when i did the setup it locked into place.

yes, i have a quietly sound, too. seems to be normal.

I think It's a new function from the last update to ensure the camera is closed(locked) when you shut your phone after using the camera

Question Fingerprint reader vs 3a

If I get a 6a I'll be coming from a 3a, which has performed flawlessly for me for 3 years now. I was looking at a 6a at Best Buy earlier and am thinking that this might be my last chance to get a new, up-to-date phone that is essentially the same size as my 3a, which is as big a phone as I'd like to have.
One big change will be the fingerprint reader. I'm used to being able to touch the sensor on the back of the 3a and have the phone instantly unlock regardless of whether the screen has woken up. But I read somewhere in here that you have to press the power button before you can use the print reader. Is this correct? I guess it makes sense but seems like it could be less convenient.
What's the story on this?

You can also tap the screen to wake it, and then touch the screen again to scan your finger. But yeah, the screen has to be on to scan the fingerprint.
So I think you have couple options to wake the screen:
1. pressing power key
2. enabling lift to wake on the phone
3. Tapping on the screen

Im also coming from the 3a (XL) and I do definitely prefer the rear reader. You can enable lift and/or tap to wake to remove the need for the power button. Plus I have smart lock on so it mitigates the need for it even more.
The on screen FB reader is definitely nice when its on a desk though as you dont need to pick it up to unlock it.

Thanks. Sounds like something I'll complain about for a while but then get used to. However, since I'm not in a hurry, I'll wait to see what the P7 looks like and also see what happens to prices around the holidays.
