(Help) Has anyone made a FingerPrint Locking Screen - Hero, G2 Touch Android Development

I was watchin 2012 last night, and i saw a phone that had a fingerprint locking screen.
i know the screen can not read fingerprints, but maybe just by holding the screen for 3 seconds could unlock a primary lock then you can have a pull down tab for the secondry..
I think it would look so cool if anyone had the skills to maybe do something....
Sorry if this is in the wrong place - i presume it is part of the development

Agreed. Would be fun!
Particularly if it looked all cool like it scanned and then had a thumb print image.
Something like it only working if for example you held down the volume button so others who tried it would fail for.
Please somebody run with this!

yer like the idea of the volume button...
i need to learn to code.....
Volume up gives accept screen
Volume down gives fail screen

that would be SOO UBER COOL!!!willing to bet ppl would pay for an app or theme like that...would be nice if u could tweak the unlock though so that even if ppl did know of the app wouldnt know what to press

Agreed, that would be awesome with the volume-key idea.
And yes, people WOULD pay for that.

I had something like this on my old iPhone (yes unfortunately i used to own one )...
On the lock screen it had a finger print scanner and pressing your finger on it used to unlock the phone... it didn't reconise different finger prints but was purely a part of the screen that when touched unlocked the phone.

I think the volume idea was initially and also should be
Press volume button (either) along with touching the screen to get accepted.
or
have it fail after a short time lapse with no buttons being pressed.
That way if someone else picks up your phone and has the "wrong finger" they won't know to press volume as well so will always fail

There's also something similar for symbian, when you place your finger on the screen the display tells you it is scanning, but it also emits little beeps or clicks, you have to release your finger on at the user specified right time to unlock it, i.e after 3rd click or 4th click or whatever.
Using that along with the volume idea would be good.

There is already a couple of finger print unlock apps on the Android market last time i looked.

Something like this:
Search for the package: innerfour.fingersecurity

finger security
theres no package like finger security on my market but i know it exist

so glad it was not just me then that thought this was a great idea - My plan of action is to track it down.......
Lets all have a easter hunt for it....First person to find it gets a kiss or a thank you - which ever they want.....

Phone dialing while in pocket, unsure what to do :/

Hey i have a quite a bad problem. My phone appears to be unlocking its self very easy and ringing people in my pocket, today it rang 8 people in the space of an hour. Ive got pocketshield but this stops it picking up calls, not ringing them. Im unsure what to do. I dont even know how its happening, im thinking the top button must keep getting pushed in my pocket or something.
Any ideas/apps to lock phone after wakeup? I dont want to put the pin on it because it may end up locking my phone instead! plus its a bind having to enter a pin every few minutes. Something like pocket shields scroll down the screen etc would be good. But i see no option to enable it for when waking up.
Thanks.
I've had no such issues since using S2U2. Give it a try!
Or LockMeLite - much lighter than S2U2 and doing just what you want - locking the screen and hardware buttons when power button is pressed and unlocking the screen on incoming call so you don't have to unlock to answer and still keeping the buttons disabled so you can take it out of the pouch without accidentaly answering/ignoring the call.
Me too.. LockMeLite has been definitive for me. No more "lost" calls by hardware.
Fk
My solution was to stick a crystal case on it,it recess's the power button so its not pushed by accident.
if u press and hold the phone icon bottom right it locks the screen , to unlock pull out the stylus.
the problem is its not to do with calls or texts, i have pocketshield for that. Its to do with the powerbutton keep getting knocked. At least i think it is.
holdign down the phone key to lock the screen sounds like a gd idea ill look into that.
And yeah getting a protective case might solve it too. Ill cehck that out too thanks, though i do kinda like the sleak design. I gues its gona get ruined proably lol.
:EDIT:
Simply locking the screen before turning it off works a charm! thanks. Now im just wondering, is there an app that will just auto lock it when i turn screeen off ? Just makes it all that easyer so i dont forget and call people again!
I had the same problem before using a belt case. I tried s2u2, but it's lagging. Now I'm satisfied with Pocketshield. Just work in its setting and you can have it work well.

Again - LockMeLight. It locks the screen automatically when the phone goes to sleep and you have to slide the screen down when waking it to unlock it. On top of that it disables the hardware buttons when locked, so no accidental calls are made when you unwillingly wake the device even with the screen locked.
original case
i use original htc case for hd.

Am I the only one who hits the power button with the keyboard extended?

I've searched but I can't find any one else complaing of this problem and it's driving me nuts.
When I extend the hardware keyboard to type, my finger often rests on the power button turning the screen off. Does anybody else face this problem? Is there a registry hack to disable the power button with the keyboard is extended?
Thanks
jejeje
Same problem!!!! so frustating!!!
No you are not the only one; I also have this problem; when writing message I touch the power button accidentally a lot and the only solution I could come to was to be more delicate and careful when writing
Regards,
Yep, same problem here! A really silly thing to miss - there's not particular reason to not have the power button on the right at the top rather than the left.
all the time....
very frustrating,
..then I try to open it, wait a fraction of a second, click it again for fear of not having pushed it enough the first time, ... and I end with the sleep mode on the phone , .. so I click it firmly for a third time finally opening it..
timewaste...
same here

Add me to the list.
Which makes me wonder, why didn't they place the power on the top right?
Well at least I know I'm not the only one. Still hoping someone smarter than I will find a way to disable it with keyboard extended
@vdKarel I would have found those post had I spelt button with two t's (#)
I wasnt having that problem until today actually. lol. funny you bring it up. After discovering this, i did find it a little inconvenient where the power button is placed
happens some times. probably the power button would be better in an other place
I do it all the time as well
I use it a lot (pages and pages of word documents written on it in the train) and it doesn't happen...
When I hold mine with keyboard extended, my left index (which is the one which could hit the power button) is folded, so it hits the left side of the keyboard "block" (no power button here) then goes under the screen "block" and holds the back of the keyboard "block", it doesn't press the left side of the screen "block" (which has the power button).
Do you guys have your left index extended for it to be along the left of both the keyboard "block" and the screen "block" ? I don't see how else you could be hitting the power button...
PS : On my TyTN, this allowed me to turn the PPC on and off with the left index tip with the keyboard out, this avoided waiting for the screen to rotate when I knew I'd wand it in landscape when I trun back on.
This only happens to me after ALMOST completing a 900 word e-mail . . .
You're not alone, and there are fixes for this:

For the Tilt 2, this doesn't happen. I don't know if it's because of WM 6.5 or something AT&T implemented or what, but the power button has no effect when the keyboard is out. I actually want to find a way to enable that because at times I want to put it in sleep mode while open.
Why do you have your fingers extended?? I never have this problem in my TP2!

Optical joystick, trackpad - issues / low sensitivity

Hi All,
Two weeks ago I became a quite lucky Desire user, but recently I've noticed decreasing sensitivity for optical joystick.
I have a feeling that at the begining it worked better, but right now from time to time it just stuck, non respond or just have a weird behaviour.
What I obsereved that if you will use piece of cloth (t-shirt, case - whatever with "structure" material) it works perfectly. In that case it response quickly, really nice.
Made research using diffrent "sides" of finger - and slightly better when you use side not a finger tip. Also trial on my colleguage proved that something is wrong.
Have you faced with such issues?
shall I wear gloves ? any other workaround?
is there any application to calibrate this optical pad?

Same issues =(
Got the same issues since the beginning. Actually the pad is nearly unusable for me. Strangely in the text box it works much better than other places. It's a bit annoying and there are times I wish I had a mechanic trackball like the N1...

I too have the same problems and it's been like that since I had the phone.
I just thought it was normal and never use it as it's pretty much useless!
I just tried using the edge of the t-shirt and it works PERFECT!
Miss the trackball I had on my G1... that was uber sensitive and worked perfectly.
Might bob into the three shop and see what they say.
Phil
hmm dont notice any different with shirt / edge finger or normal use o.o where are you guys testing this on test or the menu? usually one vertical swype up on the menu makes the cursor go 1 page or sometimes 1 page +1
It really works perfect with the shirt.
For example right here to switch between posts. With my finger I often need to slide multiple times over the pad til it reacts.

It's really annoying.
Just tested on switching between homescreens and scrolling through texts and I have to do it multiple times with my finger and then it doesn't always work but then work absolutely fine using my t-shirt.
Surely HTC must be aware of this problem. I have seen quite a few comments on this now.
Phil
Yeah he's right just tried with my T-shirt and it actually amazed me how useful the trackball became.
Shame my hands are not made of cloth.

I have just emailed HTC to see what they have to say about it.
Perhaps if i wore gloves all the time just in case I needed to use the trackpad... oh but then my fingers wouldn't work on the screen
Hmmm on this thread I can scroll the while page in 1-2 swipes try putting more pressure on it

Nope! Pressure makes absolutely no difference!
When I use my t-shirt I barely have to touch it to get it to go exactly where I want it to!
Definately a problem with it. Perhaps they had a dodgy batch of optical sensors!?
Hm... Maybe a guess. I know, certain people have papillary lines on their finger tips, which are rather noticeable and are really easy to identify. The others don't.
Could this be that the trackpad sensor too much relies on identification of those papillary lines, and in case they're less visible, is unable to "decipher" the moving finger?
And yes, I also can confirms that:
1) Trackpad is more sensitive in Messages app
2) Trackpad is more sensitive when flipping left-right than up-down.
The optical trackpad is like a mouse, it detects image changes, the cloth (normal t-shirt cloth) has it wires parallel both vertically and horizontally, and it's really simple for the sensor to read it (the lines going from left to right or from down to up).
Now if you move the sensor on a completely blank surface for it's resolution it won't read any movement, no matter you move it half a mile. By blank for it's resolution I mean if it is 600dpi and the material has no difference larger than 1/600 of an inch. I imagine the Desire's optical sensor is no gaming Logitech laser mouse with 1200dpi 50-100dpi at most.
Back to the finger, everybodys fingerprints are different, (CSI people thanking the nature), so the lines on your finger can help or give a hard time to the sensor, I've also had problems using it, in the browser, on a hundreds of links page like a forum, I gently move the finger, the selected link stays the same than just jumps 3 links down, over the link I want, I go back and it goes back by two, again over my link, and the third time I get it right, or use the doubletap and the touchscreen ...
Maybe somebody can find the calibration/sensitivity file for us to edit.
PS: Sorry for my English, I did my best...
I think you got it in one there!
I just tried with my finger side-ways (so the lines on my finger are going the other way) and it works perfectly. I think that must be why it works better going sideways than up and down.
Bit dissapointing really... what was wrong with having a trackball?!
P.s. Your english is very good...nothing wrong with it!
Late night email work around
"Just don't wash your hands too often"
Ok so I just got a reply from HTC about this... and their very helpful suggestion:
"Dear Philip,
Thank you for contacting us. In regards to the track pad, I can help you with that. Warning: Resetting your phone will erase all data stored on the phone memory completely. Remember to back up the phone information and settings. To perform a hard reset please do the following: Go to the Home Screen Press Menu Tap Settings Tap Privacy Tap Factory data reset Tap Reset phone It is also possible to perform a factory reset by using the hardware buttons on the phone. 1. With the phone turned off, press and hold the VOLUME DOWN button, and then briefly press the POWER button. 2. Wait for the screen with the 3 Android images to appear, and then release the VOLUME DOWN button. 3. Press VOLUME DOWN to select CLEAR STORAGE, and then press POWER. 4. When asked to confirm, press VOLUME UP Will I lose all my calendar events, contacts and emails if I have to perform a factory reset? Yes, you will lose your data on the phone. However if you have set up a Google account on your phone, your data is synchronized and backed up on your Google account. To setup a Google account, please do the following: Go to the Home screen Press Menu Tap Settings Tap Accounts & sync Tap Add Account Tap Google Tap Next Tap Sign in Enter the Google Username and Password Tap Sign in The handset will now automatically sync Contacts, Calendar and Gmail with the Google account. I trust that this resolves your query, please do not hesitate to contact us again if required."
Is it just me or does this seem like a totally irrelivent solution. Surely doing a hard reset will do absolutely sweet FA to resolve an issue with a hardware related issue?!
HTC are so poor.

Prevent WP from shutting down when locked

This has been bugging me for a while now, and it is not clear to me, why anyone would want to shutdown the phone on the lockscreen.
What happens is, when i sit down, the on/off button is presses against my thigh and turns off the phone. I find this to be rather annoying, escpecially since this makes the phone rather obsolete.
is there any way to disable the shutdown functionality while the phone is locked?
is anyone else having this problem or is it just me?
Nope..... sounds like you have a faulty unit to be honest mate lol
seriously? your phone doesnt turn off when you hold down the power button on the lockscreen?
i find it hard to imagine that this might be a hardware issue. nevertheless, i use an HTC Mozart.
Mine shuts down too.... but I have a HD2 with WP7 so I wasn't sure if it was a WP thing or a WP+HD2 thing.
Get a case and stop having it hit your thighs. I can honestly say I have never had the power button depressed on accident on my Samsung Focus, with or without a case.
Not really much else you can do unless someone finds a very specific reg tweak.
Oh, thanks for your feedback. well that sucks..
What were they thinking? Who would be too lazy to unlock their phone before turning it off? I really resent the iPhone, but at least its developers had the common sense to add a confirmation slider to the shutdown process. Even WM used to show a dialog box.
Ive now got a pin code on the lock screen and disabled the sim pin. So now, at least, it turns itself back on and connects to the network automatically - provided I acidentally manage to hit the button again of course xD
Hope we find a registry setting that will do the trick, or maybe MS might even be bothered to fix this in one of their very regular updates...
Im with you on that , my focus (with the case ) shuts down easy when barely touched , Im really surprised the guy with the Focus hasnt accidently shut down, then again if you dont ever put it in your pocket or hold it the wrong way ,I guess that wouldnt happen, Im sure theres a hack for it, but not having (full) access to registry is limiting the chances of creating the string!

On/Off Button Placement

Anybody else bugged by the fact that they put the on/off button, like, the least reachable place on the phone?
I always have to juggle the phone around in my hand to reach the button, and then I have to juggle it back to reach the unlock ring. I mean, the two things I do most, pressing the on button and then sliding the unlock ring, are placed as far apart as possible. It's oddly cumbersome for such an elegant device. It's just a matter of time until I drop the damn thing. (I guess that way HTC sells more replacement screens... )
The volume buttons are where my thumb is, but I never use them. They are mostly in the way and I press them more by accident than on purpose.
Any idea whether there's a way to switch the on and volume buttons? There's probably no mod that can currently do this, but is this technically possible?
That is where the purpose of volume button to wake comes in handy. And yes, it is possible to do that.
Naah... not with me..
Yes it was a little bit difficult... but now I've become used to it....
there's a a mod for that
volume buttons to wake up the phone
use rc 3.0 or else search its thread
ckpv5 posted a long time ago
ummm... try searching -apm+ volume to wake
Sent from my HTC One V
I am using the volume wake thingie. But it will, you know, change my volume setting if I listen to any audio. Which I do a lot.
Also, you can't lock the phone with it. Which precludes my main use of the button: unlock phone, check clock or notifications, lock phone.
Anyways, I wondered about the technical possibility of just switching the buttons.

Well, then there is public interest in finding a way to mod the keys, right?
Try a two second timer.
I have somewhat large hands, and the placement doesn't bother me. I can reach the button with my index finger and reach the ring with my thumb.
I do really miss having an external camera button.
yeah its not too much of a problem for me. i can hit the power button, and then use the unlock ring, but it requires a bit of stretching. i dont have to move the placement of the phone in my hand though.
