[concept + request + some questions] Pull down desktop to unlock - Android Software Development

Here's an idea. Like the way we pull down the notification bar, at the lock screen, we pull down our home screen or last used app to unlock.
Technically, I have thought of one possible way doing it. Using widget locker, place a widget at the top of the screen, it looks like a bar or an arrow pointing downwards. It takes a snapshot of the screen when the phone is locked or screen timeout (probably widgetlocker locked intent broadcasted?). You pull it down to a certain point, while showing the snapshot last taken, and tell widget locker to unlock (widgetlocker unlock intent - are there any?).
So that's my idea and with very little chance I will developed it (cuz I don't know how!). Hopefully someone will take this concept and developed it and/or anwser a few technical questions:
1. How to take screenshots and uses it in the program?
2. How to determine is it pulled down to.a certain point, especially to support different screen sizes?
3. How to use only 1 row of widget space but pull it across a screen?

I just downloaded wp7 lock and I must say that my concept is similar to wp7 lock, but entirely reversed. Pulling down instead of up, and pulling home screen instead of lock screen.

Reports say that the 'double tap' the top to scroll back up the contacts list...only works on the contacts list. So, hopefully...our devs can make it universal on any screen that needs to be scrolled. Also, maybe a 'double tap on the bottom' as well. (maybe the double tap on the bottom can take us back to the previous screen position)

A way to swap the menu and recent apps key assignments. I'd rather do the left key for recent apps and hold the home key for menu. Also stock ICS theme with all Touchwiz features
- Reduce home button delay - edit: just found out you can decrease delay by going into s-voice settings and disabling double click home shortcut.
- Improve lock screen wake up speed
- 5 instead of 4 lock screen shortcuts (e.g. i'd like to be able to have phone, messaging, email, internet, camera)
- scrolling wallpaper would be cute
- prevent flashing white notification led when phone is charged? or was it for something else? This actually woke me up last night and wouldnt stop until i pulled the power cable.
- ability to swap icons around on the launcher when the grid is full. Is it just me, am I being stupid? because when a launcher page is full, I can't move icons around anymore. I can move icons into folders, but when I drag an icon over another one, they refuse to swap places. Is this normal touchwiz behaviour? if it is, it's going to make organising my home screen severely annoying!
I'm such a dork, I got super excited that someone besides me said scrolling wallpaper. lol

That white LED woke me up too, its way too bright.
I solved most of the other problems by installing NOVA launcher though, phone wake up is instant, home button twice as fast (but generally still slow) and no issues with full icon grids

Yeh, a flashing bright white led is a strange choice. A dim green one would have made more sense.
Might try another launcher then. Do apex and nova have lock screen shortcuts?

NOVA uses the touchwiz lockscreen from what i can tell, so shortcuts are there.
I have actually removed the lockscreen entirely, the phone wakes up much faster.
As for security, I use an app that uses face unlock only when you try to get to settings, play store or any other app you choose. This way I can access my phone quickly for usual things but have the security where i need it.
I'd quite like the ability the rearrange the controls in the notification menu.

How can you customize the lock screen shortcuts? Thanks

1. Auto light level is too low and too slow.
2.RGB LED too light and turn on time is too short.

What can be improved:
- Get rid of the horrible sharpening that creates ugly halos around text on non white backgrounds. (it is software as using power-save L1 in browser eliminates the sharpening)
- Remove a little of the pink tint in color temperature
- Reduce the millions of always running (unquitable) services running to a minimum so that home screen restarts and browser out of memory are less of an issue.
- Make the home launcher system persistent
- Remove the unnecessary animations that slows down the speed of waking up the screen and returning to home screen.
- In browser add ability to access tabs and url bar by tapping menu when in full screen mode.
- Add text reflow to browser similar to htc. The default fit to screen option butchers the look of the webpage overview.
- Add the option to choose between LQ, HQ or HD in youtube app.

Lockscreen Wrong Size

I notice right off the bat if I wake my phone by pressing my lock screen, the widget I'm using (not just Calendar) is condensed. I need to manually drag the square down to see it in its entirety. However if I scroll across to other widgets on my lock screen, they are all the proper size. How do I set it up so I can see the full view of my center widget whenever I unlock my phone without touching the screen?
To be clear, I want picture 1 to look like picture 2 the moment I wake my phone. Is this possible?
Edit: I'm running stock vanilla Jellybean

It's not possible running stock. It was designed that way because the bottom half of the screen is needed for your unlock pattern.
You'll need to flash a custom ROM. They do this so you can unlock your phone quickly without having to drag up the widget.

Galaxy S5 Lock Screen

My biggest problem with this lock screen is many.
If I want to use the finger print part of the lock screen I have to use the stock lock screen. Not to big of a deal BUT...
No widget support
No notifications on lock screen.
Two much other wording all over the lock screen. Instead of showing alternative password how about hide it until my finger print is wrong. Instead of emergency call hide it until I need it. Why scroll Verizon Wireless on the left bottom.
This is Kit Kat were is widget support and notifications??????

I absolutely agree with I don't get why it gives me three choices to unlock my phone from the bat rather than wait for me to get my fingerprint wron

This is why AOSP is the way to go. Screw Touchwiz and all that crap. Can these OEMs stop shipping devices with there UI skin and just give us the real android experience. Lets make all the phones like Nexus devices.

Lock screen widget?

Hey all.
Does anybody have any idea how you change/remove widgets from the lock screen?
I'm using knock knock code, I have the large clock in the top half but wanted to change it to a calendar.
I can't for the life of me work out how your do this!
Anybody got any idea?
Thanks.

Swipe the clock widget to the right, then swipe back to the clock/unlock screen. Then you will be able to long-press on the clock and remove it. Then you'll see 'tap to add widgets' and you can choose the calendar.
Yeah, Ive tried that, It just does this lol.
Try it without Knock Code (with swipe).
Yip, Tried that ... Same thing ..
Trying to work out what the arrow at the bottom is for, it dont see to do anything.
I never even used to have the knock knock cope option, I updated my phone via the support tool, I have the knock know code but cant change the lock screen widget. I mean even when im on the lock screen i used to be able to swipe right to start the camera and now i cant even do that.
I'm thinking something has been changed in the update, Can anybody on the same build as me confirm they can still swipe from the lock screen to start the camera app and change lock screen widgets? ... Its definitely different than before.
Try using swipe lock screen and lock your device. Then wake the device. Swipe down on the clock. Then press and hold the widget. You should then have the ability to remove it. If you have no other lock screen widget, you will end up with a huge + giving you the option to add another widget. If this doesn't work (it should), reboot and try again.

It wont budge, Before if i had a pin code at the lock screen set i could just swipe the pin code area down, It then ask me for my pin, I could then long press the clock and a option to "remove" would be at the top of my screen, When the widget area was blank i would see a large + sigh, I could tap this and be given a number of widgets i could put there!
The clock just wont budge now no matter what i try!
Same Deal Here
Ever since the update, it seems I can't remove the default clock widget either. Swiping down does bring up the arrow (just as it used to) but it won't stay on long enough to long press the clock (as soon as you take your finger off it goes back to normal). I'm going to do some experimenting with WidgetLocker, see if I can't get it back to where I want it (obviously figuring this out would be ideal, but I'm starting to wonder if it's possible anymore. I've seen articles about enabling widgets, but haven't found what they're telling me to look for).
Edit: Got it figured out. It turns out I had somehow turned off the lockscreen widgets & disabled the feature through Secure Settings.

Don't know if you've been back to this thread but changing Secure Settings settings worked for me.

Fingerprint reader to unlock & display notifications

I'm on the latest RR, 5.3.8. Finger print function works, but there's no addition settings available to do other things once the phone is unlocked (gravitybox added some additional functionality, but no xposed in 7).
I've tried several apps that let you configure additional functions to the finger print once unlocked. The entry i'm using is 'toggle notifications'. This works, but seems to add significant lag when unlocking the phone, requiring at least 2 taps to unlock.
Any thoughts or suggestions for achieving this? Ideally it'd be nice to do a slow double tap - first to unlock, second to toggle the notification without having to move my finger from the back to the front.
hello try to download the NExt lockscreen in Play store..work wonders for me...
Is this app similar to widget locker from years past?
I don't know if I want a full blown lock screen replacement. When I did have widgetlocker instsalled, i used the same apps as were on the home screen. Layout was very similar. Really all I want to do is use the fingerprint reader as another button. It's far more convenient to tap it once unlocked than to move fingers to the front of the phone to swipe the status bar down.
