[Q]Is it possible to enable NFC at lock screen?

I love NFC and was hoping to use it a lot with the chips I bought. However unlocking the phone first is really stupid. Is there some way to enable NFC to work at the lock screen? So that the NFC unlocks it or something? It is kinda useless to me now. BTW I have root, but no recovery. I don't want recovery because of the triangle stuff.

why u dont just enable the NFC all the time? i dont think with NFC enable/disable the battery drain is noticable

I think you understood me wrong. NFC doesn't work when the screen is off/locked. That sucks, because I want to use it when coming home/leaving home and I really don't see the point in using this if I have to unlock it first.

Yeah,
Even the manual says it only works when the screen is unlocked.

Yeah but that is a flashable zip. As I said I don't have and want recovery.

you are sure that a file for s3 (different firmware as note 2) will work?

I'm not trying. Also I just hope there is some way without recovery.

I really hope there will be an "official" way at some point.

If anyone is making a mod for this, maybe we can bypass the security concerns if there was a pop-up that requires you to approve the tag first, and be pre-approved for known tags. This way security is not compromised, and we also get the added convenience as well.

You can just extract the zip using something like rom toolbox, and then copy the files to there respective place manually, that way you don't need recovery.

Seconded, would love this for my note ii

I'm using this method which is for Note 2: http://forum.xda-developers.com/showthread.php?t=1999569
Works fine. Have set up a few tags and using it with Secure Settings, NFC Task Launcher and Tasker to do a number of things without having to wake the phone up or unlock first.
The only issue is that if you put your wallet in the same pocket as your phone, it will beep when it scans the the NFC chips in the credit cards
The method replaces the NFC service file in the system directory so at the very least you need root access.

Thanks for the link, looks promising. Now i just need to figure out how to install it without using clockworkmod...
Edit: Kindly, today, dr.ketan told us how to do it http://forum.xda-developers.com/showpost.php?p=36824840&postcount=1
All works for me, woohoo but whenever you use the browser or chrome, it crashes the nfc service

I'm experiencing that problem as well now. Also on launching YouTube service. It's annoying and makes it more inconvenient than having nfc screen off. There is another method through XposedFramework which is non destructive on the stock NFC.apk file. Might be worth a look?
www.villainrom.co.uk/forum/microdownloads/nfc-lockscreenoff-enabler.9/viewfile
But before that, I tried to restore my NFC to a non crashing version after doing the CWM method. I couldn't get my stock NFC.apk back, even with TitaniunBackup. Had to do a selective /system restore.

Multi-Window on CleanROM 1.0 (At&t)

I noticed that the extended multi-window feature on this rom does not allow me to split the screen with any apps (out of the ones that I have) other than the native apps that were able to do it with the OTA update. I can add as many apps to the mutli-window menu, just cannot split the screen. I was wondering if anyone has had this problem and if there is a known way to fix it. Much credit to scott for creating this rom though... everything else seems to work fine. It's really fast! Thanks for any and all help!

I've experienced some issues with some of the 23 Toggle Mods that are out there breaking the multiwindow functionality for the ones you manually add to the mwc app. The only way I was able successfully fix it was to do a dirty flash of the ROM again. Sometimes you may get lucky by removing and re-adding the apps but that didn't work all the time for me.

[MOD][APP] 4.2.2 NEXUS 4 | Exchange Email with Disabled Security Permissions

Exchange Email APKs for Nexus 4 4.2+ stock with security permissions disabled.
PLEASE READ THE FULL POST...ITS ONLY A FEW LINES!
Created using rustamabd's method, Full props to him.
Circumvents PIN AND Encryption requirements.
Created from stock and CM10.1 images, cannot confirm that it'll work on other ROMs.
UPDATEs:
5/8/13:
added CM10.1 compatible APKs
9/9/13:
New: Patched de-odexed STOCK 4.3 APKs added. Also, things were getting kind of busy, so I put the apks in a zip thats named per version, that was there's none of this renaming BS.
12/16/13:
Added CM10.2 compatible APKs
1/4/14
Added CM11 APKs
2/18/14
Added PA4 APKs
Tutorial:
Force Stop Email, and Clear Data.
Using Root Explorer (or something like it), go to /system/app and rename EmailGoogle and Exchange2Google apks and odex to EmailGoogle.apk.backup and Exchange2Google.apk.backup, etc (always important to have a backup that way you don't F everything up)
Download and unzip appropriate archive for your OS version
Move the files to /system/app
Set permissions to rw-r-r-
Reboot device
Note: You will have to allow activation additional security permissions when Email asks for it. But you should not be required to encrypt your device or set a PIN. Also, you will have to reload all your email info after this.
As always: for educational purposes only, can get you fired, jailed, tortured, etc. Use at your own discretion.

Can you explain what this does? A short description for nubs like me?

Basically stock email app may force you to set a security pin/pattern due to corporate security policies. This effectively makes any of your lock screen widgets, slider shortcuts unusable. This mod will allow you to bypass the exchange security requirement from exchange servers.

Haven't tried it yet but has anyone noticed battery drain with this version? I stopped using the one in the other thread (http://forum.xda-developers.com/show....php?t=1749921) because it caused alot of wakelocks. Exchange Services became my 2nd highest battery drainer

Yeah I read about that on that forum. Supposedly it has to do with incomplete syncs with the exchange calendar. I never experienced the drain, but disabled exchange calendar sync since I don't use it that much anyways. My battery life has been reasonable, roughly 10 hours with moderate to heavy usage, 14-18 if I'm not on it a lot.

The zip in the thread I posted works fine and does not have any extra wakelocks at all. Battery drain is normal.

You have to clear your current exchange account and set it up again AFTER you have replaced the files from this thread and set the appropriate permissions. It works quite well, specially also because it ignores the need to encrypt the device. Suberrrr!

Just tried this out today. The files worked great with PACman ROM. It asked for permission to become device administrator, and then to enforce security polices. I allowed both, but it actually didn't enforce any new security polices that I could tell. My email syncs now. Thanks!

Try redoing the steps.
1) system>apps>email and force Stop and Clear Data. Do the same for exchange if it's running.
2) replace EmailGoogle.apk and Exchange2Google.apk in /system/app with the attached files from the OP.
3) change permissions to rw-r-r
4) restart device
5) setup your email. It will ask to activate permissions like pin and encryption, but once you click activate, your email should work fine.

Do you use multi window?

I rooted my note 3 last night and installed the mods to add other apps to multi window. That was my main drive to rooting. But I don't seem to use it that much. I find it easier just to use one app and then click the home button swipe up on nova which gives me my recent apps and then use the other apps. That works better for me and is really fast. I was just wondering do you guys use multi window? And if so is there a certain way you use it? With any specific apps?
Sent from my SM-N900T using XDA Premium 4 mobile app

I use it from time to time when I'm on the go and I have to open a spreadsheet as well as my email for example, where I have to take certain figures from a worksheet and use them in my email to someone... that's just an example... Another example is when I have jotted down several numbers that I have to do some work with, so I open my notes, say, on the top, and the calculator on the bottom... It WILL come in handy--trust me.

I thought I would use it more, but I've only used it 3 times total. I guess more app support would help, but even then I don't I would use it much.

i have used it a bunch of times
will do it more when i can add whatever app i want to it (stock with root)
i just hate it when it does it on its own

Yeah adding with Wanam module works great. It also adds a hotboot function which is handy.
As for uses, I've used it loads of times with my reader app. I can pop open a browser to search a definition or get more info on something. I found that apps are limited in how they work with each other though. For example I can't drag a reference image from a browser into sketchbook. But that's an issue with sketchbook and not the multiwindow function.

Thanks, i used the multi window manager from the play store to use all apps. As for how much I actually use it, not much. I've actually been using pen window more since we can add any app to it. It's become quite useful.

I did all this and enabled the apps I want...but how does it work now?
They are not showing on the right slide out thing for multiwindow...does it not show up there, but we can do it by opening those apps?
Also the wanam app is a lifesaver...lots of things on there
-nvm went to edit and they are all showing now

I actually use it a lot more now on the note 3 than i did on the note 2. The app groups really makes it more useful to me. Specifically i have an IRC/Chrome combo, an IRC/Youtube combo, a Chrome/youtube combo, email/gmail combo, gmail/chrome combo, and quite a few more like that, you can see the theme... I also enabled auto multi window for supported apps, which i find really useful, so sometimes if i click on a youtube link in some apps, it will play the video on the bottom half, or if i click on a link in a text message, it splits and takes me to the webpage... Each evolution of samsungs software gets just a little bit more useful imo.

Set knock code as unlock method, but the grid doesn't show on the lock screen, just the pin pad. Slide aside works.

Yup. Same thing. I could set the knock code in the settings but after locking the phone, it takes me to the pin screen and as it doesn't accept my actual pin, i have to enter 5 wrong pins to get forgot pin button and enter my actual pin to unlock the phone. And yes slide aside works.

Make sure you set permissions correctly before reboot.

644 = rw-r--r-- correct?

Are you saying that the screen can be awakened by knock? I thought that was a feature specific to Snapdragon 800 series devices and kernel related code was required to make it work.

No, it is purely an unlocking type - when you wake your phone a grid overlays that you tap based on the pattern you set up.

I really like the SlideAside feature. It's almost like a multiwindow feature like on Samsung devices, but saves screen space.
I haven't tried the knock code feature, but I'm going to pass on that anyway. I just have no interest in any of LG's "Knock" features. I mean, I might learn to like them if I had native implementation of them on my phone, but I think that even if I had the G2, I'd probably disable the features (assuming the power button is eay to press I guess)
.
@JaySee5:
Did you modify the files in any way to make the SlideAside option appear in the Settings?
If not, I'm wondering if the Jelly Bean Aspect Ration Correction feature can be ported into KitKat and still appear in the settings list. It was just a system file from what I recall. I'd try it myself, but I lost all my Jelly Bean backups. They were all on my phone and when upgrading to Kitkat, the internal SD got wiped.
(I really need this aspect ratio option back. I rely on some old apps that dont display correctly on my phone now).

I didn't do anything. This is other peoples' work. I just made a thread for it so everyone can find it easily.

I'm just throwing this here:
After having Slide Aside working flawlessly for a full day, the app and system began crashing after about a day.
Slide Aside would crash if you try to add more than 1 app.
Settings would crash whenever you accessed a system-made apps list (I don't know how else to explain this). The only way to fix this is to factory reset the phone.
An example would be Settings>Apps
In fact, I was able to repeat this crash every time by going to Settings>Apps then scrolling over to "All."
If I scrolled down the list at any speed, Settings would crash at the exact same point.
Another example would be the apps list in Titanium Backup, which is not system-made. This means that the problem does not occur in this app,
I'm not sure yet if this is actually caused by SlideAside or GravityBox. The latest version of GravityBox (which I'm using obviously), has a changelog entry stating, "Fixed severe bug in AppPicker affecting ring targets/quick app tile icons." This COULD be the culprit, but I'm not sure yet. I'm currently debugging the issue though. I just factory reset the phone and updated GravityBox and don't have SlideAside installed. Everything is working as expected ow, but I'm going to give it a couple days to see if the problem happens again. If not, then I'll install SlideAside and repeat.

Oh ok. Thanks.
I still wonder if the Aspect Ratio Correction file can simply be copied to the system and have its permissions set correctly- no editing of the file's programming. Then maybe the setting will appear... Hmmmmmm

Just an FYI: This feature needs a special kernel to support it. There were some Jelly Bean roms that included a modified kernel, but they were only working on the E988, from what I remember.
Even those kernels weren't perfect though. People reported high battery drain.
