[Q] Mute sound when screen turns off app

Does anyone know of an app or way to automatically have Android mute the sound when the screen is turned off and then set it back to its original level when the screen comes back on? Unlike with phones where this obviously wouldn't be desirable, for tablets that often sit in your room etc. it seems that this could be desirable behavior.
If nothing exists I think I may do this as my first "Android development" project! I'd like to see if anyone else thinks this would be of interest too!

Check out "Tasker" in the market.. It's like $6 but its one of my must have android apps.. Does all kinds of things based on events/triggers.. For instance, on my tablet when wifi near DOES NOT equal "home network" it toggles on the pattern lock, otherwise it's the slide to unlock option..

[MOD] NFC for Verizon GS3! NFC Enabled While Screen Off / Locked

***UPDATE***
I upgraded to ParanoidAndroid and had to use a different apk. I don't know who made this one (i downloaded like 10 from xda and tried about 4 before it started working), but here's the winner:
techneesh.com/paranoidandroidnfcscreenoff.apk
*****************
Hey guys,
I searched for hours but could only find reports of people *NOT* getting this to work on the Verizon GS3 (hence the name of the thread).
I tried hacking my stock Nfc.apk using dex2jar & modding the smali files (after looking up the appropriate values to change using decompiled dex2jar classes.dex's nfcservice.java), but after much frustration decided to just go ahead and try the existing versions out there.
By the way, if anyone is looking for how to do this (decompiling/modding/recompiling an apk) with 4.0.4 (and getting the 'bad magic number with smali/baksmali), refer to the comment on May 8th in this thread.
I'm pleased to report that mayhemer's AT&T version (for the SGS-I747) works for us Verizon folks!
You can grab it on his thread here.
I've also uploaded it to my server. Here's a direct link:
techneesh.com/Nfc.apk
I posted this in the Development section because I would really like to encourage devs to work on modding Nfc functionality further. Also, this is a more advanced mod for a system app.
Google Wallet did not throw errors with this .apk (as it did with others), although I have not tested it yet.
NFC reads trigger the nfc tag's function and the alarm/beep, but do not turn on or unlock the screen (while it is off).
Also, I just got a whole bunch of NFC tags in and plan to make some cool products for them... if you have any ideas let me know on my 3D-printing-on-demand-for-xda-samsung-gs3-folks thread.
Note- I am on Bean's Custom Stock R3.1 07/28 (I know, I need to upgrade)
4.0.4, SCH-I535, Baseband I535VRLF2, Kernel 3.0.38imoseyon+, Hardware I535.10
Instructions for apk:
1. Get apk onto your phone
2. Stop NFC (or else your phone will start lagging // freezing after the next step)
3. Copy the apk to /system/app/ with a root explorer and overwrite the existing Nfc.apk (you should make a backup first)
4. Change permissions to match other system apks (rw-r--r--)
5. Reboot & re-enable nfc. Profit. Share your uses.
For zip you should be able to just flash in cwm.

What reasons would one what NFC enable while the screen is off/ phone locked ????

oh man, don't get me started!
think about it - you get to your desk and want to tether / turn on music / silence phone. just tap it on the nfc sticker on your desk. done.
you get into your car and want to enable gps / turn on music / navigate somewhere. tap your phone to the nfc sticker. done.
i have a lockscreen for security and even though it only takes a second to open it still adds up over the course of the day. the ability to quickly do (any) task on your phone without unlocking it or even pressing a button is huge.
for example, I canceled home internet last year when I got LTE but this means I have to turn on tethering every time i sit down at my PC. using a tasker nfc-activated command I can just touch my phone to my desk and it's on. time saving and just fun.
or maybe you are in a meeting and miss a call and want to call them back - have a pre-programmed nfc sticker that will command your phone to set an alarm for (e.g.) 1 hour. tap your phone to it without fiddling /unlocking/interrupting your meeting further.
what really made me think of this is while I was looking for something behind a wardrobe and wanted to turn on my LED flashlight on my phone. how cool would it be to have an nfc sticker (on your keychain? on a sliding mechanism on a custom techneesh.com case on your phone?) that could basically act as a 4th hard button to do a custom function (in this case, turn on the LED flashlight without 1. turning on screen 2. unlocking 3. going to home screen 4. finding LED flashlight app and opening)
and yes, this is for real

I'm trying to get this to work on CleanROM 2.5, with the G7 baseband. I followed the steps correctly, but it doesn't to anything different than the stock NFC
I can still read my tags when screen on and unlocked, but i get no response with the screen off or on and locked.
Triskite, did you modify the .apk from the linked At&t SGSIII thread at all? If not, would it be safe to try the other apk's listed there?
Thanks!

the apk worked as-is for me - only thing i can think of to try is to turn ON a lockscreen? (I use the pattern security one)
safe? I certainly can't assure that... but would I try them? yes.

I went ahead and tried the .zips from that thread
I flashed the nfcmodI747_lockscreen.zip flashable from CWM and it works like a charm!
Once i did this, i wanted to see if the screen off nfcmodI747_screenoff.zip works, and it sure does (again, flashed via CWM)!
Don't know if it matters, but i did not disable NFC from settings before i flashed them via CWM.
Thanks again!

Just saying this is as of the moment the most unsafe mod someone can implant or put a nfc tag somewhere to run malicious code on your device. While I do not condone hacking of any sort, I know the possibilties of what these hacks can do from different forums (not naming any).
TLR, caution with this one guys. Especially if you're using wallet using my guide......

Ok...what are these tags you're talking about? I've never ran across NFC tags in "the wild"...do you buy them and then tell your phone what to do when it reads a certain tag?

Yea, I understand the risks and all.
I agree that it is a major security vulnerability for someone that wishes to highly protect their information.
I just wanted to try it for a proof-of-concept kind of thing.
Honestly its pretty quick to flash these via Cwm. I went back to stock Nfc.apk for parties/bars this weekend (Too many people close to me for security comfort), then today I flashed the lock screen version for my school week.
It would be really cool if it were possible to toggle this.

Can somebody post the stock nfc apk file(s)? I guess they are needed to take the OTA update after mucking with Wallet, and i didn't save them.

I just tried the nfcmodI747_screenoff.zip with the latest paranoid android (2.16) and it does not work. The NFC settings disappear entirely.

True, but this involves active running processes like GPS which can drain your battery. From my experience, NFC has no noticeable extra drain, not even the screen off modified version. Not to mention how easy it is to use the NFC programming apps versus Tasker, IMO.

[APP] Moto Skip tag creator

Here's a quick APK to allow you to create a base Skip tag to activate NFC unlock. Apparently non dev devices don't have this available out of the box.
A few notes.
You can't re-write this tag using the Moto X. The NFC service intercepts these tags and won't deliver them to another app to write (even with foregroundDispatch set up as far as I can tell). You can freely overwrite it with any other device though and it will work with any app again on the Moto X
This should allow you to use a tag as a Skip tag as well as expose the NFC Lock Screen option and Manage NFC Unlock options under security settings (see screenshot) if you don't have an official skip tag. Using this you can create new skip tags using any writable tag and add them to your supported tag list.
Grab it here: http://goo.gl/5bUqPW
NFC Lock settings

FYI: Once you have the NFC unlock option in the lock screen part of setting you can just hold up any writable tag at the add new tag step, and the phone will write the skip code on to the tag.

I have a skip, and have used it on this phone ... but, if you have the NFC unlock option in the lock screen part of setting you can just hold up any writable tag at the add new tag step, and the phone will automagicly write the skip code on to the tag. You can even use a blank tag as your primary tag. No Skip tag needed.
No, the phone doesn't tell you this.
Just an FYI.

This is for everyone that does not have this exposed. Apparently this is most carrier devices. The NFC unlock lock screen does not appear until after they scan a skip tag. This is just to encode a single skip so they can scan it and effectively unlock the option. Dev devices don't appear to have this issue (gsm at least) as it is available out of the box and works fine with any writable, supported tag.

Yeah, saw that. Edited post to show that.

Thanks for the app OP. It worked great. I programmed two tags. I also have an assortment of magnets I'm testing for turning on NFC.

What am I missing? I have a VZW Rooted Moto X (non-dev). I installed this app but don't see the NFC security options. I even went into the Skip app and scanned a tag and it said created successfully.

Tap that tag you created, it will take you through the setup. After that the NFC unlock options will be present.

That literally does absolutely nothing. I've tried with two tags. It says write successful but subsequent scans (while app is open or closed) do literally nothing. FWIW, clicking "settings" does nothing either.

Beats me. This just creates a copy of a skip tag. Once the tag is encoded as a skip tag it won't be delivered to apps any longer and should be picked up by the moto skip sw. You didn't freeze these moto apps as recommended in many threads to save battery? Outside of that idk. It's handled internally by the NFC service and the moto software.

Wait do I NEED to have a Skip already? I froze some apps but don't think anything related. I can check.

You do not need to have a skip. That is the whole point of the app.

There was an update to Skip Setup in the play store. I installed it and now everything is working. THANKS!

This seems to get NFC tags formatted properly, and then the skip application itself sets them up and says they're good to be used, but after that point the phone no longer responds to them - almost as if the NFC tag just doesn't exist when you hold it to the phone. They're still listed as being paired in the NFC Unlock. I wipe them with another phone, and all of a sudden my moto x "sees" them as an NFC tag again. They can't be used as skip tags past the setup process. GSM Dev edition here with latest skip app update.

That is done on purpose. The Moto X incerpets the tag before an NFC app will recognize it. The tags will still work to NFC unlock the phone.

You're right. I noticed it working once out of many tries and now i tried again and figured it out - they only work when the phone's screen is on and at the lock screen. They don't work like the skip itself, where it can actually wake the phone/turn on the display and unlock it. That's why I didn't think they were working. Interesting.

The real skips have a small magnet in them that cause NFC to wake up.

[Q] Disable access to Quick Settings on Lock Screen - coming anytime soon?

I've recently configured the fingerprint scanner on my Lock Screen but notice that a whole bunch of phone functions are still accessible as Quick Settings are still available (well, some functions are).
Now, I'm not the first to notice this - this question has been asked before here and other places but an answer has never presented itself - not on stock firmware anyway. I think this may be a Lollipop "feature" so my question is does anyone knows if Marshmallow still does this or has it been fixed? I say fixed because locked phones shouldn't be turning stuff on & off in my pocket!

Not sure, I know samsung requires you're fingerprint or pin etc to turn on or off functions.
I'd check my Nexus 6 but it's in the mail to my brother right now.
Just to confirm, you can change the setting with it locked, the quicksettings don't just show you what's enabled? I don't have my Z5 yet so I can't check lol.
Sent from my SAMSUNG-SM-G920A using Tapatalk

No, not just a read-only display area. You can adjust brightness slider, toggle on/off Wi-Fi, Bluetooth, Flashlight, Airplane mode, Auto-rotate and LTE. My regular unlocked Quick Settings config has Mobile data and Stamina mode too. Weird that Airplane and LTE toggle are available on Lock Screen but somehow Mobile data and Stamina are "too important" to be left there.
I've read that removing all these from the regular Quick Settings will remove them from the Lock Screen cut-down version too but that's not really the point. I expect phone functions to be locked when the phone is.

Strange, I can see the use case for it, but it should be a toggle 'allow on lock screen' or something.
I've wanted to toggle bluetooth or airplane mode from the lock screen before, but at the same time I can see why having the ability to do that could be bad (evil coworkers lol)
Sent from my SAMSUNG-SM-G920A using Tapatalk

its not just about evil coworkers, its about thieves turning off Data+Wifi so you cannot use Device Manager !
a big security issue IMO.

Aye, though with features like reactivation lock is less of a issue since they won't be able to wipe and use the phone anyway. Still a security oversight though.
Sent from my SAMSUNG-SM-G920A using Tapatalk

Seems I've answered my own question
I tested this on a Nexus 5 running Marshmallow and it's the exact same scenario unfortunately so it doesn't look disabling Lock Screen Quick Setting access is coming to the Z5 either.
I've also tested an iPhone running iOS 9.1 and access to the Control Center (which has Airplane mode toggle too) is configurable to NOT be available on the Lock Screen.

Yes that's totally nuts! What's the point of using fingerprint as security feature when you can turn off the phone using on/off button and all you mentioned above from the lockscreen! I used to use Xperia xposed or gravity box to configure it so it wouldn't but no root here.

Ah yes, forgot about on/off also being available. Turns out on/off is also available on iOS 9.1 lock screen even with Control Center access disabled so both iOS and Android behave the same there.
So it kinda cuts down the use cases for the find phone functionality on both.

Even on Marshmallow on the Nexus 5 Google have made it so location doesn't display on the toggles on the lockscreen for security of lost devices. But you can disable data still, the thing you need to tell the device to locate itself... Big fail...

Lawyers?
Makes me wonder if Google/Apple lawyers have piped up with, "You know, one of these days some guy is gonna hunt down the thief that stole his fancy phone and get himself killed. Now we don't want to be liable for that so let's leave an option open to the experienced thief to turn off the phone!"
Too fanciful?

Any way to disable Google Assistant on Lock Screen?

If I disable Voice Match, Google Now disables everywhere unless I re-enable the Voice Match. Then saying "Hey Google" while the screen is locked and off triggers it.
I need the good old way of Google Assistant only working when I am on Home Screen, not when I am in any app, not when the phone is locked or screen is off, only when I am either on home screen or app drawer.
Any way to do it? Any magisk module or anything?

Not all functionality is available when locked such as I can turn my WiFi connected lights on without unlocking but need to use the fingerprint scanner to interact with apps most apps.
It's funny that I wanted my previous OnePlus 5 to be able to do this particularly with AutoVoice Tasker scripts but now that I have this feature with my OP7Pro but I'm not so comfortable with the phone and potentially Google always being the fly on my wall.
Sorry but I've not spend any time trying to address the issue as you described as I'm still deciding if the convenience is worth the voluntary surveillance.
I regularly watch the Daily Pocket now YouTube show and have seen him toss his spying Amazon Echo as he hates that it listens and then inundates him with adds related to what he was talking about. At least Google has only done that after I've done web searches although I'm sure this is just a ticking clock from changing.

That is one of my main concerns, apart from battery drain that'd be there with constantly on mic (though have heard that newer QC chips have minimized that drain), google will always be on the listening mode, no matter if the phone is locked and in the pocket.
And I know that not much could be done from the lock screen, but it's annoying, my phone was on the table, and I was discussing something with my friend. I might have said something that would have sounded like hey google, and suddenly I hear "Here are the search results". Picked up the phone to see that it picked up certain words from the conversation, and had searched for it. As we were in a quiet room and the media volume was full, it wasn't very pleasing to suddenly hear that.
