Allowing NFC to work even with screen locked (Android Lollipop) - Xperia Z2 General

I decided to share this with you since it took me several hours to find it.
I bought some NFC tags to configure some tasks.
For example, I have 1 in my car that when i swipe my phone over it, it connects bluetooth, mobile data, gps signal, set screen bright to maximum and open GPS app.
Problem was, I could not use it with the phone still locked or with screen off making mandatory to be manually unlocked 1st, which takes a bit of the automation of the process (yes, I am very picky )
This post bellow, allows you to detect NFC tags with your screen still locked or off as long your phone has the smart lock feature!
I have a Sony Z2 and a LG G3 and this guide worked for both, thing is, the screen needs to be on, but can still be locked.
This solution worked like a charm for me since to turn on both screens i just need to double tap the screen.
Guide:
http://howto.highonandroid.com/andr...android-smartphone-with-nfc-android-lollipop/
Will work on:
– Nexus 5, Nexus 7, Nexus 10, Nexus 9, Nexus 10.
– Samsung Galaxy S6/S6 Edge/S5/S4/Note4/Note3/Tab S.
– Sony Xperia Z3/Z3 Dual/Z Ultra/Z2/Z1/Z.
– All other Android phones/tablets that SUPPORT “Smat Lock” feature and running on stock Android Lollipop.

I just know I'm going to use this eventually.

As the title says "Allowing nfc to work even with screen locked " It didn't work for me.!
Followed everything.. It just made my phone to disable lock[just swiping without pattern or pin] whenever I pair it to a nfc device.

One year with Note 4, my thoughts.

So it's been around a year since note 4 was released, and I wanted to make a thread about my and Yours experiences with Note 4.
Let's start with why I have chosen Note 4.
Specs
2K display with 500PPI+
Android and redesigned TouchWiz
Camera
Root and V4A(Audiophile here!)
Phablet, I like devices that are 6 inches and more, cause I got huge hands.
Old "Good" Note family.
And here couple of reasons why I hate it
MicroUSB stopped working and I can't no longer charge my device.
Had to buy new battery because first one become swollen and I got like 20 minutes battery life.
Phone turns off itself like 10 times daily
Phone gets super hot when charging it, even with the new battery.
Sometimes my calling function stops working and I can't call anyone nor anyone can call me until I reboot my phone.
Same thing happened to me with the Note 3 , and my friend and my dad that use Note 2 have also lots of battery and random reboots problems.
I really do love this phone, but it hurts me that Samsung makes phones that are so faulty. We pay a lot of money for our phones and we want them to work at least for 2 years, not 6 months!
For the next 5 years I won't buy any Samsung phone, maybe HTC, LG, Nexus, Sony Xperia, IPhone but definitely not a Samsung phone.
What are Your problems with Samsung phones?
- GPS doesn't work properly
- the finger print scanner is a joke
- the Lollipop updates were horrible (no mute toggle anymore, apps for pulling down the notification bar stopped working, apps can't turn mobile data on/off anymore, notification & settings layout was changed to white, battery life got worse, notifications take like 5 seconds to appear in the notification center, recent app button lag, camera-gallery lag, air command shortcut app doesn't work without root anymore, the Samsung's one hand operation tools are not really thought through)
- still no theme store added
- apps get randomly killed by this smart manager thing, which makes the phone totally unreliable
Overall a good phone, but the software (Samsung & Google) leaves a lot to be desired I'd say.
15 minutes ago I lost my Note 4 forever. It just turned off itself and I can't get it to boot nor charge the battery. Thank You Samsung. Now I can't even sell it! No download mode, no recovery mode, it's just dead. I have no luck with Samsung devices. Two of my Samsung Smart TV's broke too. I don't know what to do.

T-Mobile Use

Anyone using the Axon 7 Mini with T-Mobile? If so, what is your experience and does the wi-fi calling feature work? Thank you.
Can't get votle to work and no wifi calling
Sent from my ZTE B2017G using XDA-Developers mobile app
More to this it seems after doing 4636 the volte is turned on(can't be turned off) but it doesn't seem to work?
Sent from my ZTE B2017G using XDA-Developers mobile app
I've had the axon 7 mini since October 31st, so I've had a few weeks with it on T-Mobile and it works just fine. Signal strength seems better than my Note 3. The camera wasn't as good as my Note 3 but I just got a software update yesterday that included improvements to the camera. Haven't had time to test it but nice to know they are pushing updates now.
I don't use Wi-Fi calling so I can't comment on that. Sorry.
T-Mobile WiFi calling doesn't work, there is no option for it in the settings. Of unlocked phones, I think the Nextbit Robin is the only one with that feature available. I got my Axon 7 Mini on 11/28/16. With the latest software update, VOLTE seems to work on T-Mobile, at least the HD symbol stays on during a call and the sound is very clear. Band 12 shows up using the LTE Discovery app, when I go to my basement to look for a weaker signal. I already have a software glitch, when I touch the ZTE Locker option under select a wallpaper under Settings, I get an "Unfortunately, Settings has stopped" error instead of the list of options. Restarting the phone doesn't fix it. Also, ZTE removed the settings option of placing a message on your lock screen, which is available with the pure version of Marshmallow 6.0.1.
The soft button for switching to the speakerphone has a 3-4 second delay after you push the button. On my ZTE Zmax2 the camera app had a nifty level with the 9 line grid on the screen which I found very useful. The Axon 7 Mini camera app has no grid lines options at all. For some reason, the phone did not include a Calculator app and it does not work with over-the-air FM radio apps. The proximity sensor doesn't seem to good, my face touching the screen has hung up on 2 people so far. Also, the ability to transfer certain apps to the SD card was removed from this phone. But it is still an option in stock Marshmallow.
no wifi calling. VoLTE is amazing

I am new to T-Mobile so can't comment about WiFi calling, but would like to correct some of the information in the 2nd portion of the post.
The 9 grid lines are available under the "Manual" mode. I wish they were available under "Photo" mode as well. There is a calculator app included under Toolkit. I suggest you don't bother. Get your favorite free calculator from the Play Store (there are a ton of them). The removal of moving apps to SD is not unique to ZTE, as many companies are experiencing problems with Android integration of SD into storage. My personal preference is to keep music, videos, map cache, and other media/data on the SD, and all apps on internal storage.

Thanks for the information. I see what you mean about the calculator, not even a memory function.

Ticwatch E - Unable to use Google voice search

I just got a Ticwatch E. It's fresh out of the box today using Android Wear 2 and all that (I gather it originally didn't support Android Wear, but it does now with the latest firmwares I guess.) One of the biggest reasons I finally updated to a modern smartwatch (my Pebble Time has served me very well and done just about everything I ever wanted except just a few things) was to be able to use the Google Assistant for (mostly) hands-free operations like getting directions while driving and etc without having to pull out the phone, unlock it, etc etc. (Especially since I prefer that my phone stays in my pocket when I don't need to do anything complex and at all times while driving.) I setup a bunch of stuff but just found out I have a huge problem in that this is the one thing I needed that absolutely does not seem to work.
Whenever I attempt to actually use the assistant by either holding the power button a moment or "ok google" (which I want to keep off to save battery life, but I turned on to test this) it just pops up a blank screen with a picture of a circle with an arrow (basically a refresh symbol which seems to be used to say "loading" a lot on Android Wear.) I've tapped around, tried sliding from each direction (of course left to right just backs out, but I tried the other three too,) waited a long time, and tried unlocking the phone after a quick google search. I have no clue what if any apps other than Android Wear need to be installed, but I did install the Google Assistant and already had the actual Google app itself installed. (I'd rather have only whatever is necessary, but for now I'm kind of trying to throw everything at it.) I also have the Ticwatch app itself installed even though I don't need or want the fitness tracking stuff.

Upgraded to STABLE Android 12 One UI 4? How's it going?

I'm curious to know from those who updated/flashed to the STABLE (NOT BETA, please!), how is your phone working so far? Do you have any issues? Were the issues from the BETA resolved?
Format: (So that it's easier for people to associate with their device)
- Model: Snapdragon/Exynos
- Openline or Branded
- Updated via OTA or Flashed
- Dirty flash or FULL reset?
- Issues:
- What do you like/dislike:
Your post will greatly help the community.
Hopefully carriers will start pushing the Android 12/One UI 4 update for the Note 20/Ultra OTA this upcoming week. The S21 on VZW pushed it OTA the same day as the European roll out, so maybe its not too far behind for US carrier branded Note models.
-Exynos
-Unbranded
-Flashed with Odin (Switzerland firmware)
-No issues detected
I generally like the new animations, the new popup PiP design (rounded corner and possibility of resizing the window), battery life seems to be as good as before. The possiiblity of making AoD turn on when receiving a notification is nice and resembles the old Motorola active display feature. New Pro Mode layour for camera is better. I also enjoy the integration of the same animation for loading screen system wide, it's a nice touch even though I think the animation itself could be better. The gesture system from Google (Swipe from sides and bottom) now is usable with a 3rd party launcher, though it's still a bit clunky.
The only thing I dislike is the brightness bar in the notification tray which is now "tall" all the time and takes more space.
I must say that I didn't notice any particular difference coming from the second Beta (for Exynos there were only 2 beta releases), the first one was a bit clunky but the second was already well cooked. As far as I've seen there are no new issues introduced with this release, the 2 I knew of that were introducd with Android 11 still stand: Samsung gestures (swipe from bottom, the 3 way one) don't work as smoothly as in Android 10 because the recents gesture is not interactive and triggers only on finger release, the "currently playing" notification in the tray sometimes resets (when you reboot for instance it appears showing the last thing you were listening to).
Overall I'm happy about the update, it's a minor one for sure but they succeeded in not screwing up.

Thank you for this, @Sprov!
How about on connectivity, WiFi, Cellular, 5G, WiFi Calling/VoLTE, don't you have any issues? Connecting to BT devices like Buds Pro or any audio devices, Google AUTO etc.?

Everything as smooth as always, now that I think about it I had to pair again the Buds Pro during the first Beta (it was working at the beginning though) because the media would play but there was no sound output. In my area there's no 5G to test. 4G and calls fine as before, WiFi, GPS all alright. I don't use Android Auto
I have two very annoying issues with One UI 4:
- Overheat
- bad animations (lag, fps drop and etc)

I guess the Swiss version won't work with BTU?

It works with BTU, in Odin use home_csc for retaining your data.
Clean install here and everything is smooth and I feel it have a better battery life then before..

Hello ,
Exynos
Phone buy Samsung Shop web
Flash with Odin PC , Switzerland firmware
Just update , i became from beta 2 , i use home csc . I conserve all data
My phone is more smooth , more reactive . For battery , it's difficult to say it's more better . Good works .
Codec LDAC is functional since a few update , i like that with my Soundcore Life Q35 .
I like this update but it's not a big update .

Not sure about the high temperature, but I read in other forums that factory reset can't fix the laggy animations. I think for this we need to spam on Samsung Support. Also, I did heavy debloat with some PC app, and seems the battery life is drastically improved. I may share the result in a few days.

Does LDAC stick once it's enabled or do you have to keep enabling it? Do you also need to go into developer settings to activate it?
Sucks. On my Verizon it killed the top of the display; first row of icons. Posted a thread in Q&A.
My advice is: Don't!
Immediately used adb app control to kill updates.
Now what?
I'm still on beta three, I haven't had any issues with any of the releases myself 986U1 ATT
- Model: Exynos
- Branded
- Flashed
- Dirty flash for starters, then did a FULL reset?
- Issues: Lots of little ones, Bluetooth Buds continually disconnecting as well as Galaxy Watch 4, Alarm keeps turning off when hit snooze button instead of snoozing,Google Assistant does not always work with voice wake up, this is a problem when driving. Plus a couple of other small things I can't remember at the moment.
- What do you like, most things I like, Dislike that Android Auto for Phone screens no longer supported, have to use Assistant Driving Mode that does not work in landscape mode and is absolute rubbish.
I have now gone back to Android 11, till I see that these problems are fixed.
I did try the Beta version before the stable one, and that have most of these issues as well, so thought should have been fixed for stable release.

I have no (AS IN NONE) issues with the Stable A12. Everything is working as it should and the device is gr8!
- Exynos from Malaysia (XME)
- Unbranded
- Updated via OTA
- Dirty flash
- Issues: Whenever I use the notification panel it gets laggy, like it were set at 60hz
- What you like: I love it, it handles overheat better.

Those who updated to OOS Android 12 - Is it still bad?

See title. Thinking again about updating now that we have another update out in C11 (I believe this is the most recent).
Would you if you had to chance to stay on Android 11? Still very much on the fence.
I haven't had the time or energy to do a clean install, so maybe these issues wouldn't show up normally but here is my experience so far:
1. Forcing the hz to be always 120 is no longer as simple and must be reset every boot
2. Also custom dpi must be set every boot
3. Widgets sizes are all off, some too big and some too small.
4. Always on display is forced on, and almost always doesn't turn on for about 20 seconds when taken out of a pocket, forcing a press of the power button.
5. When always on display doesn't show the fingerprint icon (either configured or after a few seconds), fingerprint scanning won't activate
6. Aptx TWS+ simply doesn't work anymore. Defaults to notmal aptx or aptx hd
7. Reply in floating window doesn't function at all
8. Notifications that are unread but still in the drawer don't show up on the lockscreen
The new fingerprint animations are dope though
crDroid 8.4 is running really nice!
There a couple things I don't like. The new animations are good and a change of system sounds/ringtone is nice. The UI is mostly a sidegrade if not a downgrade in utility. I felt the same going from 10 to 11 and now 11 to 12. I guess I will just get used to it.
What I don't like is the horrendous navigation buttons. What idiot at OnePlus thought it would be a good idea to space out the nav buttons an inch apart? Makes reaching my thumb over (and I have big hands) a pain in the ass. It looks stupid as **** too. I had to switch to gesture navigation mode because of this. Also they added crap like shelf and the qualcomm voice thing/quick device connect which are annoying as I couldn't get rid of the notifications. I tried turning quick device connect off in settings and it wouldn't work. had to mute the notification.
Also in recents/multitasking when I hit close all apps it should close all apps but instead it goes back to the app I was using. This is annoying as I developed the habit of closing all apps and shutting of my phone in a clean slate.
I will do a follow up post of bugs as I encounter them
Thanks for the responses guys. It's shocking to me that widely released software has this many issues still. I may just stay on A11 then. I am eyeing the Pixel 7 in Sept/Oct and I'll leave OP behind at that point. It was a good run.
