My XT will be here next week (hopefully) and I'm curious how NFC works. I understand the technology but how it works on the phone itself. It is another radio that you can turn on and off? If so does it have a noticeable impact on battery if left on, or can you leave it on all day and not worry about it?

Yes it's another radio with a toggle.
No it doesn't really have an impact on battery life.

Pretty much sums it up. You will also notice that when sending a larger file (pictures for example) it will automatically switch on Bluetooth on both devices and send like that, then switch if off. I haven't really used it yet, which is a shame.

This pretty much sums it up from both a spec and uses point of view.

I bought some Smart Tags on a whim and have found them both useful and frustrating. Useful in that they can be used to perform several actions on the phone at the same time and frustrating because you have to unlock your phone before anything works (so I couldn't just jump in the car and swipe the phone by a tag to turn on Bluetooth and make sure my sound mode is set to normal!)
My thread has useful posts (by other members,mainly) about different types of tag and different apps to use with them.

Hello!
Would like to know how can I set my LG Optimus 4X HD (with app or settings) so it is always on line while on 3G or WiFi even if I lock the phone?
I have unlimited 3G plan so I don't care about data traffic and no mater what I do battery last 1 day, so I don't care about power saving.
Thank you, Denis

Settings - Screen - Set screen timeout to 30 minutes or something, It's not smart to keep 3G - Wifi online, as it will wake your phone from deep sleep and It won't even last 1 day like that.
You gotta find a kernel with no deep sleep support.Also why do you want your 3G to be on while screen is off? Thats nonsene.Most of the apps that use your 3G would keep your phone from locking the screen, so your phone wouldn't enter deepsleep and they could resume downloading.If you wanna save battery by locking the screen, just turn the brightness down.
Try to delete bloatwares, that increased my battery life from 1 day to 2 days, with moderate usage.Try using some different kernels also.
Whats your purpose locking the screen while 3G is on? WiFi hotspot or something?

by default, your 3g should stay on when you turn the screen off/lock it, if they're enabled. you only need to do some things if you DONT want it on when your screen is off.

Background services? Push notifications? It makes much sense (are you sure what you're talking about?). But on the other hand: if there are apps requiring network for such purposes, they usually take care themselves for this requesting corresponding wakelocks from time to time (background services). Just push notifications work differently, but here the core system should take care.

That's plain nonsense. Though they could do so (e.g. requesting a full wakelock), they usually don't. Want an example? Ever heard the chime for a new mail having arrived, as you set your mail client to poll at certain intervals? I've never seen the screen turning on for new mail polls. But admitted, I'm not constantly staring at the screen

You wouldn't receive emails 24/7, turning 3G on once an hour or two is enough to check notifications.You wouldn't notice any notifications until you turn on the screen anyway.

Nope, I just didn't get what he means.He should try to be more specific.His question is short and simple, no one can do anything without knowing what he is trying to do.Theres multiple solutions to a problem mostly and he is just focused on one of them.Keeping screen on 24/7 is not a solution.He should try to use third party apps, some should have options to notify him in some way, It's just nonsense to keep screen on 24/7.

Wrong again. I hear a chime (new mail notification sound), and then I maybe turn on the screen to look what it was.

(emphasis mine). He didn't ask for the screen being on, but for the connection. While for 3G, to my knowledge that's the case anyway (as @Flying_Bear already pointed out), this is different for WiFi depending on the settings (WiFi standby policy).
@denis1304: In WiFi settings, you can configure this in the advanced menu.

Hello again
Let me explain on example what's that I want from my phone if it's possible.
I use app MightyText or MySMS and while on WiFi it works instantly but if on 3G and phone screen is off for some time, sending SMS start to lag and you need to wait for 10 or 15 minutes for SMS to go through.
Or when I want to install app from my PC over play website its takes also 10 to 15 minutes to start installing app.
While on wifi it takes much less time or start instantly.
Hopefully I explained what I want so you can help me or I expect too much.
Thank you, Denis
While this won't help much: In both cases you mentioned, you are actively performing a task. So you could simply switch on the screen to speed up the action. I've no idea how to do that in a different way automatically, at the moment at least.

Nice quotes...
In both cases, turning on the screen and 3G once an hour is enough.
Turning the brightness down could save him from locking the screen, that was my point.

It is what he exactly asked.He wants his phone to keep 3G - Wifi online while screen is locked.So keeping the screen on wouldn't be a solution, and a third party app could help.
Well, good thing you actually tried to help OP with a few words.You could do that before instead of arguing with me.XDA is no such place, if your commenting on some troubleshooting topic, you should focus on OP.Correct anything I write wrong, BUT focus on OP's question first, thats your priority.
@denis1304
You should try JuiceDefender, I know it's actually a battery saver, but I remember it had some options to sync stuff even while screen is locked.You can set how often it syncs, or turns on the Wifi or 3G to perform such tasks.
Hi! I have an odd problem... My wi-fi is dead, for sure, and I want to disable it, forever. It just keeps trying to turn itself on, and it drains my battery.
I read on some sites that I have to delete the wi-fi libs from my phone and I'm fine.. but where are those libs? I've found a thread on this topic, this one http://forum.xda-developers.com/galaxy-s2/help/permanently-disable-wi-fi-s2-t2604586 , but there's no answer... I just want to know what to rename/delete, as I said, my battery lasts something like 7-8 hours if I put on some music in my headphones, and 13 hours max on idle.
Hope somebody will answer.. Thanks

If you want help you need to provide what ROM are you use, do you use some scripts etc... I am not sure what the problem is, but you can try to do factory reset.
Look, I am using the Stock room, it's rooted, stock kernel. I don't need to fix my wi-fi, it's broken (hardware problem, my bluetooth is dead too), i've tested it, there's no fix for it, but to change the mainboard, and I'm not going to do that. What I want to know is which file to delete/ rename in order to have my wifi permanently disabled. I am using the stock 4.1.2 ROM.

When you turn off WIFI from options it should be off, it will not search network. What is happening to you?
Look, when I say it's a hardware problem, it's a hardware problem, I did test it, the result of the test was that "[NotSet]" driver thing, means my wifi is dead. I just want to know what I have to delete/rename/ whatever in order to have my wifi permanently disabled. That's all.I don't want to repair anything, ok?

Ok, do not pull a gun and shoot at me please. I say, when you disable wifi in options, it should not turn it self on. So I do not know why would you need to remove anything… But you can wait for someone else to answer too.

Try to uncheck scaning always available in advanced settings of WIFI.
I don't have any option like that one in my advanced wifi settings tab... I did change "keep wifi on during sleep" to "never", but I don't think it worked out... Where is that wifi driver located? Maybe I can delete it, and then I'm happy...

Hi there, I have searched some forums and I haven't found any sollutions for this. There was mod for Nexus 4, when NFC modded application was being installed on device, therefore there was ability to use NFC Tags while screen is off. So, I'm searching for AOSP android 5.0 screen unlocking via NFC Tag, becouse Smark Lock doesn't work as it seems (checked, running pabx build).
Is it possible to do?
Any sollutions?

You need root, and Xposed Framework. Then install the module called NFC LockScrenOff Enabler.
It allows you to use it with screen off.
Personally i prefer to only enable NFC on lock-screen (not screen off), because many times i hold my phone and wallet on top of each other and i keep the bus pass in there which the phone can read.

Not possible in Lollipop even with Xposed Alpha 2 version. Plugin simply doesn't work. It's sad. The only way to unlock device from screen off is to use some Tasker/Llama apps and trigger them with BT HF/USB charging. Then it can go to Car Mode which unlock the device, but only on the rom with hardware profiles like CM12.

When you move the phone slightly the underdisplay fingerprint glows, can anybody tell me how to turn it off? I want it to goow only when I press on the phone, is this possible?
Doesn't seem so, as it's the only way to know where to put your finger.
It seems to be implemented at the "hardware level".
I'd you mean the fingerprint icon that shows up when you pick the phone up, you can't disable it currently.

OP, which firmware are you running? I'm on EU rom and there used to be a bug, which resulted in being a workaround to disable the fingerprint icon.
However now there is a dedicated setting, see attached, which allows turning off the icon

Damn, i might flash this rom just for this feature, it's super annoying at night, and it keep activating the screen in my pocket.
Can you flash it over the global rom, or does it require a wipe? (probably..)

Hmm given the rom is different, I'd say you may run into issues. But with that said, worth a shot! If dirty flashing, perhaps wipe system and the caches, then flash rom and magisk (if rooting), and keep those fingers crossed!
Any issues then yeah do a clean install

Does seem somewhat like this because if that and the ambient display is disabled, the fingerprint doesn't respond from screen off. But if that and/or ambient display is enabled, it works. But at least something has to be turned on keeping at least some part of the screen awake.
I chose to enable ambient but disable fingerprint icon because ambient goes around the whole screen giving me peace of mind from burn in unlike the icon
