Nfc not working - OnePlus 6T Questions & Answers

Hey guys, i have a problem with my nfc. It is not working on few custom roms (Havoc and siberia os). I have attached the logcat. The device maintainers cant seem to replicate the error. Can anyone tell me a solution? I really like havoc os and wish to install it
Update: Found out that the NFC detects cards but turns on and off when I bring near another NFC enabled phone. It also works on few custom ROMs like RR and treskmod but not in havoc os

I am expirencing also strange behavior with my NFC on LOS 17.1 microg oneplus 6T.
Sometimes it works sometimes not, don't mater if NFC is switched on in the tools bar.
I will test in the near future if other phones with NFC enabled are toggling my NFC functionality and will come back to you.

Hello @Swordsman001 ,
I have news to my NFC problem. I think that there are much more people to have it without knowing it.
I discovered with the help of reading out the log files that every time I was putting my oneplus6T to charge the NFC was working. I was able to reproduce this behaviour all the time having LineageOS 17.1 with microg.
At the moment I unplugged the phone from the charger it was not working anymore, but not always. Sometimes it worked after unplugging and sometimes not. So no reproduction for this situation.
Later I put my phone to stock OS with the Microsoft tool and updated the system to the newest version of stock OS.
And with the stock OS, I had the same problem! No NFC working as it should.
Here the same situation as with LOS17.1+microg:
Plugged into power charger NFC works every time.
By unplugging from power charger NFC works only sometimes.
Than I found this post about a Samsung S9 that loses NFC functionality if the battery level is under 70-80%.
So I charged my phone to 100% and unplugged the phone and NFC was working.
I waited till the phone had about 79% charge and NFC was also working.
Then at 78% charge the NFC was not working anymore.
So i charged it up to 80% again, unplugged the power adapter and NFC worked again.
This time it is working with 78% but from 77% away not anymore!
I have to test more to see a pattern correlated to the state of charge and working NFC.
I am not lucky in finding something in the internet but did someone know if the samsung S9 and the Oneplus6T have something in common regarding NFC that could explain this behaviour independent from the rom? Hardware or drivers?

Verizon GS5 Not Charging

Hello, recently I've had a problem where I can't charge my verizon galaxy s5. It's been rooted for a while now (about 7 months) and one day it just stopped charging. I assumed it might be the rom, so i switched to a different one. This didn't fix the problem so I decided to back to factory default. This didn't fix the problem either and I have no idea what the issue is. The battery works just fine because I can charge it on my friends gs5. Also around the same time as it stopped charging, the vibration mode on the phone no longer seems to work. This wasn't fixed by the switching of roms either. Any help would be greatly appreciated. Thank you.

check battery status in settings what is it showing AC charging not charging discharging

[Help] Moto X Play won't show it is charging but the battery is working properly.

So, 2 days ago I was charging my device (XT - 1562 Indian Version 16GB) and when I saw the phone after 2 hours the battery was still at 15%... so I got into the battery options to check if the battery was charging and it was showing "Not charging"(SS attached) so I rebooted my phone and it was still showing not charging, I also did a factory reset and still the problem was not solved so I booted into the fastboot mode and there it was showing that the battery is charging. I was confused so I thought that there may be a firmware problem(6.0), so I downloaded factory images of 6.0.1 and flashed them(the BL was locked) and still the problem was there then I unlocked the BL and flashed 5.1.1 and problem still persists. Guys pls help me. :crying:
Also please tell me how can I flash 6.0.1 again via Fastboot mode. I am still at stock 5.1.1
Edit : Update : Now I have installed a custom ROM (CM 13.1 by Temasek) and now the phone is charging like it should but it charges till 82~85% and then stops charging. Cant give the phone to the service center because I unlocked the BL.

Thanks for the reply bro. I have updated the thread so can you tell me what is the problem.
are you using the original charger and cable ?? charge the Device when it's off then turn onforum.xda-developers.com/showthread.php?t=1782420
I'm having this exact same problem on my xt1575. I bought it from a nice dude on Swappa, but he seemed pretty green concerning phones in general. He rooted/unlocked it, then appears that he kept the stock ROM while flashing the franken kernel. I didn't notice this for the first day or two as I opened it and poked around for some signs of something loose/water damage: nothing.
I couldn't sleep last night, so all morning I've been doing what I can to play around with clearing caches, flashing different ROMs, and anything else I can find in the software side, but aside from somehow getting it to get past the previous cap of 4% to a whopping 25% before slamming down to 11% (percentages waver constantly), I'm stuck and desperate to figure it out. I've even tried the stock turbo charger, the stock charger for an old Moto X 2014, and as of writing this just now a Samsung quick charger for the giggles.
I have parts for all kinds of Moto X 2014/Nexus 6 lying around, so I took the risk of connecting a Moto X 2014 battery up to see how it behaved. It read the battery level around mid-seventies and didn't seem to drop at any exaggerated rate but still kind of bounced around a tad. It would charge at times, but otherwise still wouldn't show the battery as being charged. I didn't think too much of it because the 2014 is of course a different model at a much smaller capacity, so I didn't want to try leaving it on the charger for fear of overcharging. The only thing left that I haven't done is hook up the Play battery to another motorola because I don't have any screens to monitor progress and see how consistently it reads to determine if it's the battery that's somehow gone wonky.
So in summation/where I'm at right now: I'm having this same problem; I've tried both hardware and software tinkering to no avail; I feel this is still somehow kernel/software related, but I'm not sure how to completely obliterate everything to start from stock. Please forgive how scatterbrained I am right now, I'm tired yet wide awake and irritated with the whole situation; there's NOTHING I can find in the forums or elsewhere outside of stock replies like "are you using the original charger?"
My moto x play not change in normal it only charge in factory mode that to 75-82℅ only.
Let it discharge fully then put on charge without booting up

I have tried after battery fully drain, still it's not charging again I am charging mobile in factory mode. Is there any solution please help me. In factory mode i am not getting signal.
So no change in behavior. I did notice that when in TWRP that the CPU Temp value is crazy, and any reporting software says the battery is at -23.8° C and always cold, even on a brand new replacement battery (obviously send like that is what's keeping it from charging). I even went as far as to put a heat gun on it from a distance to artificially actuate any sensors and got nothing. The one time it did report normal temps it charged fine for a whole day but hasn't returned to normal since. This **** is maddening...
I know this is a long shot, but have you tried resetting the battery stats?
http://forum.xda-developers.com/showthread.php?t=1699687
I had this problem but yesterday I can solve that
First I put stock firmware
Wait for fully discharge
And wait full shutdown
I put an moto g 2013 charger (550mA 5V)and led stay on around 5 min but not charge
After put Nokia n86 charger (1A 3.5V)5 min and not charge
After i put an orginal moto turbo charger
And start to charge wait for 9%
Turn on the phone
Clear battery stats with battery calibration app
Wait for full discharge
Wait for full turn off
I put a Nokia n86 charger wait 5 minutes vibrates and start to charge like the beginning
Any other suggestions or solutions? Still my phone only charges in recovery mode. I have a aukey fast charger. Tried different kernels and roms without success.
The solution with the nokia chargers seems really strange and i dont have that type of charger.
Regards
Someone fixed this? I have the same problem and can't solve it. I have cm 13 by temasek and the first time the x play charged up to 83% but after a full discharge and a clean of battery stats, I olny could charge it via factory mode, like in stock 6.0.1
I dont know why but after i opened the phone and disassembled the battery it worked after putting it back together. Disconnected the cable to mainboard as well as nfc antenna. Then carefully pried the battery out. Its slightly glued to the mb. Then I held power button down for a few sec as read in a different forum. Afterwards I connected power cable back but left the battery next to the phone. Booted the phone and charging worked. Than I reassembled the phone Ehen I was sure everything worked. I was about to change the battery but now it works. I flashed different Roms and kernels without any improvment before. After I got it working I flashed a nandroid backup of a resurection Rom image that didnt worked before. Now its running perfect.

So, may the problem be in the pins when the battery is plugged into the mb? I'll try that! thanks!
Still having this issue, the solution with the chargers didn't work for me, neither the battery solution, suggestions?
How to solve the problem?
Please
Same issue
My Moto X Play has the same issue. It will only charge in Factory Mode. I had this issue before at 10-11 months old and had it 'fixed' under warranty, now 2-3 months later the same issue has occurred. Of course the warranty is only 1 year...
Glad I am not alone in this issue but i wish there was an easy fix! Putting me off getting another Moto...
Same problem occurred with me( Moto X Play).
My phone was not charging, it was stuck in some percentage and was not increasing or neither decreasing while plugged in to charger. But when i put it into recovery mode, it charges. But that was not the solution to the problem.
So, i have tried factory reset.
but problem was not solved.
i googled for the solution, but couldn't find the right solution. And i was stressed (I have a girlfriend, and living in very distance relationship, for me a smartphone is very important).
And was thinking of buying a new phone but not the Motorola, but couldn't afford at the time.
At the same time, i thought of repairing it by myself, by fixing the battery properly.
Without thinking about voiding the warranty and Motorola support, i unbolt every screw of the phone. and finally , finally, finally i made it by removing the battery and fixing it again(charger was plugged while removing the battery and fixing, and phone switched off while removing).
And now my phone is charging properly.
Hope I have helped every person concern to this same problem.
Thank you

Oneplus two charging way too slowly

So this problem first started when I first flashed boeffia's kernel on top of the official cyanogenmod. The only thing i changed was the kcal settings (I like a little over-saturation). But, since then, my oneplus two charges very slowly no matter what i do. I even set the charging current to 1250 in the app, but still, it was taking almost 5-6 hours to charge fully; and even then, it would not go to 100%, but stay at 92-94 and stop charging altogether. Tried draining the battery, deleting the batterystats file, nothing.
Frustrated, I switched to Resurrection Remix today, a rom that ran perfectly in the past. Plugged the phone into the wall, apps updating over LTE. after a few minutes, I saw the percentage dropping from 36 to 33 and just staying there.
Currently the phone is off, and the battery has only gone up to 12% from 10% in the last 30 minutes.
Anyone ever face this problem? Any help at all would be much appreciated.
P.S. I only flashed the rom and Gapps(mini). nothing extra.
edit- It's been two hours now and the battery's at 18%
edit 2- Battery at 20% after 3 hours. I've turned on the "show battery percentage on lockscreen" in RR. Now I don't know how accurate that is, but it's showing "charging at 1500 mAh/hour max". Now I'm literally pulling my hair at this.
I faced a similar problem after flashing dirty unicorns
Well i solved it by clean flash oxygen os 3.0.2 and changing the charging adapter it solved my problem and i flashed other roms like bean stalk.rr i dint have charging issue anymore

Trying to flash OOS 3.1.0 now... Also, I noticed, after leaving the phone plugged in, the percentage at the charging screen said 43%, but after turning it on, it was just 27%. So it's just a software side problem. Just maybe. It ain't easy getting reliable usb-c cables where I live.
P.S.- did you fully discharge/charge again after flashing? Also, nowadays we can directly flash OOS from CM with the official TWRP, right? (Haven't tried OOS in 6 months)
followup- Flashed OOS 3.1.0. Still not solved. Charging still too slow.
Also, since I have access to engineering mode (#808#), I can see that the phone is charging at an avg of 220mA from the wall.
Is my cable busted?
Currently it's going up 1% an hour(while off)
If the cable is indeed busted, can someone suggest an replacement? Idon't seem to be able to find any in amazon India.

I clean flashed the oos rom. charged it all night when morning it was 100 percent i did a battery calibration which u can find in playstore.i let the battery to drain with normal usage now i changed the charging adapter i think its 2.4amp charger i dont think there is problem with usb cable.its charging at normal speed if screen off will charge fast like 10-100 percent in 2 hrs
Guys stop wasting time flashing go directly to the cable/carger.
Battery calibration is practical useless

Solved. It was the cable. Tried a MI5 cable and "pass" finally showed up in engineering mode.
Have contacted service, will get a replacement later this week

Wifi not working

So it has came to this....
My tmobile note 3 is suffering from wifi problem which is causing it to turn of and on itselft iin such a loop that it happens every 2 seconds.
Wifi was working fine other day and this happend out of the blue.
It has happened a while ago but it resolved it self.
I was running stock kernel and rom unrooted (sigh....)
I have tried solutions which came up from google search. (wifi scanning and etc..)
I opened up my motherboard but it looks just as before when it was working.
I got a glimpse of wifi action only after phone was shutdown and it was offline charging and after booting wifi was working for 2 or 3 minutes.
Now Im runnning linageos 7.1 rom without google apps so there are no location services causing it to restart.
What might be the problem is low battery voltage not giving the wifi chip enough power to run but just to start which explaing why it was working for a little time after offline charging but I couldnt replicate the solution.
Sorry for misstypes.
If wi-fi works properly when running the latest stock rom, it could be an incompatible kernel or ROM.
Its not working properly on stock rom and kernel.
It seems like its restarting wifi by itself so fast that it cant even do the scan properly.
It loads up wifi netwoks after been shutdown for few hours but it can connect because it starts to restarts again.
Could it be a defective wifi chip? I have come across two Samsung s4 (one sgh-i337 and one sgh-i337) that work perfectly except for wi-fi. With both phones, I toggle wi-fi to the on position, I see the message that it is turning on wi-fi for a few minutes, then wi-fi just turns itself off and stays off until I toggle it to the on position again. Both phones do this over and over so I changed the motherboard and everything went back to normal.
I appreciate you comment,really I do, but replacing the motherboard seems to pricey for this old phone.
I will most probably switch to nexus 6p.
Here take my thanks as my graditude and merry xmas
You have two solution
First one,
1-turn off the phone
2- connect the charger to your phone
3- simultaneously turn on the phone
The wifi should work fine
Second one, replace your battery
The problem comes from the battery voltage which is less than 3.7v at startup of your mobile for old and fake battery which can not turn on the wifi correctly. You can use Ampere applaction to measure the battery voltage (not the current)

0% 0mV with fully charched battery

Hello everybody
Phone: Motorola Moto 4g Athene. Bought in 2016 in the USA in BestBuy. There is no warranty now.
Firmware: I have used LineageOS. At the moment, the bootloader is locked and the firmware is official (see below)
Problem:
The battery indicator shows 0%. The application "Battery callibration" shows 0mV. I culdn't turn it on directly: after "hello moto!" it is turned off. I managed to enter the system only through the recovery. If you disconnect the charging from the phone, it immediately turns off, because it thinks that the battery is critically low. At the same time in the recovery it works as long and stable as need even without charger. The voltage at the ends of the wires of battery measured by the multimeter was 3.9. After the body stood on the charge it became 4.2. Looks like the battery is charging in normal mode. All other functions of the phone seems to work properly. It seems that the phone is OK, but for some reason "does not know" how many volts there are on the clamps of its battery...
Background:
The body is Motorola Moto 4g Athene. It heated a lot all the time after purchase. As a result, the official battery have dead after one year. I bought a new one from the internet. (I am not in the US now. Motorola do not certified here. So there is no official parts, stores and service centers). The new one also died in a couple of months. During the replacement of the third battery, the plug on the board broke off. The wires from the new battery had to soldered directly to the board ... The third battery also died in a couple of months, and I have bought a fourth. Soldered. Here this funny Bug appeared.
Attempts to resolve:
Initially, it was LineageOS 14.1 installed. I did a Wipe of everything except internal data. Nothing changed. Then I rolled back to native firmware with locked recovery. Nothing. I made a Factory reset. Nothing. I have resoldered contacts from the battery wires to the board 5-6 times. Nothing has changed.
There is an idea that I overheated something on the board. Charge controller or something else. Nevertheless I can’t understand why the body works normally, except that it does not understand how many volts there are in the battery?
As a temporary solution, I consider the installation of some kind of software, which would not allow the android to turn off when the battery is low. In this case, I will charge the phone every 15-16 hours and everything will be OK. Do you have any idea about such kind of software?
Any other ideas are welcome.
