Lg v20 Nfc not working. Any ideas? - LG V20 Questions & Answers

Hello, im using dualboot with ovrdrive as my first rom and resurrectionremix as my second rom. Yesterday a friend of mine was about to pass me something through nfc and it didnt work. I also tried with resurrectionremix too and it is not working. I tried to locate any apps related to nfc and forced them to close, and it didnt work either. I tried reflashing each rom first cleaning the system, and it didnt work. Can an application be messing up my nfc? If not, what could be the issue?

Do you still have the original Battery Cover? the NFC Antenna is on the inside of the stock Battery cover. Any 3rd party Covers that do not have the antenna may not let NFC work.

Yeah. My phone still as good as new (i havent change a single thing to the phone externally speaking). The only thing i have added is a poetic revolution cover (and yes, i tried to use NFC without the cover too and it didnt work).

My Screen is Touching Itself

Hi all,
About 2 weeks ago I noticed the bottom left of my screen would activate by itself repeatedly. This mostly seemed to happen when I was trying to type something. It carried on for a while so tonight I flashed a romkitchen rom (2.3.3) (I was on 2.2.1 before), thinking it might be a bug in the system somewhere. Well the problem is still there and I;ve discovered it's always that same corner of the screen that does it no matter what orientation I have it in. I can't even sign into the market at the moment because it makes it impossible to type and the screen ends up freezing until I press the home screen.
Is there anything this could be other than a hardware issue? I did a full factory reset etc during the flashing process.
If I need to send it back would I need to flash it back to stock? I bout my phone from O2 in the UK, where can I get the correct firmware? samfirmware has loads but how do I know which one I need?
Thanks in advance!
Sounds like a hardware issue. Did it ever get rained on or something? Do you use a screen protector?
You might want to edit the topic title, although it is quite funny. Read it and think a bit.
ROFLMAO
That is by far the funniest thread title I've seen on here yet
It does sound like a hardware issue though.
Hehe....nice title

Yeah I agree with the person who suggested it was a hardware issue. Always worth getting someone to check it out for you

No water damage or anything. I do use a screen protector but it looks flawless in the affected corner

It happens at random. Sometimes it works fine. Not related to being plugged in though
I know someone that had the same issue, though it was with the Vibrant (not i9000m). He sent it to samsung, but it still has the same problem, though not as frequent. I haven't seen him in a while so I'm not sure if he ever got it resolved...

Just to eliminate all possible outside influences, take the protector off and clean the screen really well - and see if it still does it. If it does, then bring it in and try your best to be convincing

I'll see how it goes with the protector off. I think my screen is failing though as now on occassion the screen will completely freeze and I have to put it to sleep and wait a few minutes for it to start working again.
Can anyone point me in the direction of carrier specific stock firmwares? I can only find stock android ones.
Thanks,

this is so true
I've had the same problem. Unlocked SGS on Orange UK. The problem was on/off for a while but eventually got so bad I couldn't use the phone, removing screen protector made no difference.
I stuck an old Froyo build on and took it into carphonewarehouse, they sent it off and it was fixed in their repair centre. No problems since and that was 4 months ago.
Not sure how you would go about getting the operators rom on there but I'm sure you can mess around with Kies to get it to download the one you want.

Try samfirmware.com, down at the botton of the GT I9000 firmwares are the provider's ones.

Think that's what I'll have to do then. Hadn't thought of using Kies, thanks for that. I'll whack a stock 2.1 rom on there and see if it will update to 2.2 through kies.

[Q] Water Indicator Location

Hi, I'm sorry if anyone has asked this but I've tried to look up but I couldn't find anything..
Anyway, I'm thinking to get a used G2 and I want to know where to look for damage indicator on the phone before buying it.
Cheers.

Look down the headphone hole.
Some phones stick one down there
Nowadays it's located inside the phone on the main board
I'm sure there are more than one, but the biggest tattle-tale will be the one in the SIM card slot. It's the only one visible without removing the back.

Galaxy S4 : Weird issue with magnetic sensor when mobile data is on

Hi Folks,
I have got a strange issue. First let me tell my story. My phone was fallen down 2 weeks before and the screen was broken but the functionality wise(including mobile data), phone was good. After 4 days, i replaced the screen from customer care, after that my sim card was not getting any signals. then i gave back to customer care and they fixed the problem with in 5 minutes. (On the same day night, my phone was fallen again to water, fortunately nothing happened, only the speaker was acting weird, it went OK after sometime)
Here the problem part starts, after the screen replacement, for the first time i turned on the mobile data on my phone. then magnetic sensor weird issue started. When the mobile data is on, the phone feels some magnetic noise and the S view cover display will flash through screen. This will happen like once in few minutes or in a such gap. it will just flash for 1 sec and go. When the mobile data is OFF/ in the flight mode, the issue never occurs. Any idea on this
I ran few tests, the results are in the attachment, i changed SIM and the behavior is same.
When i contacted the customer care, they said they have seen this issue and they can make it good by installing fresh s/w again. But my phone is out of warranty(so i need me pay for this) and i already tried cleaning my phone, wiping everything, installing fresh ROM's..
But nothing does the job
The issue is resolved by installing the latest Black edition firmware (from Samsung service center)
iSsue is coming again, s view is flashing when i am on a call or mobile data is on.

Warranty Issue ? But i will keep that screw safe with me so that whenever some problem arises i can put it back
I had the same issue on my I9500. It happens due to faulty magnet sensor.
I had to follow up with Samsung Service Center to replace the entire screen again because the sensor is a part of it. Take a video of the issue with some other phone, it helps to explain the Samsung Service.
Same issue I had with my phone. New mainboard and new screen didn't fix it. The magnetic sensor is part of the screen assembly.
Only thing that fixed it for me was to either run a CM11 based ROM or just set my mobile data to WCDMA only.
Problem hasn't returned once since I made that change.
PS: The L1 screw method didn't work for me

Well the screw issue does not work for all. Its is just a way ok keeping it away from bwing magnetized. Nothing more. Because the senor is locayed somewhat there, then the screw works as a potential magnet.
And about the edge and w+ thing, can someone tell me how that works technically ?

As you unscrew it do it with extra caution and precautions and with a proper screw driver because in India, to be soo true, the SSC guys have a habit of checking the screws and if they find any thing weird they straight away say "ye kahin se khulwaya tha kya" (did you get it opened from some local shop) amd start showing it to the other engineers and everyone of them will say "haan haan haan, lagta hai" (yes, we think)
So it gets a bit embarassing.
And if you can..get a plastic screw from some shop (if you find any) and place it instead to fill the void.

My phone had been to service centre 3 times!
1st time - Factory reset
2nd time- Screen Change
3rd time- IMEI rewritten and software reinstall
i have shown them the recorded video but they got no idea of the issue... they are clueless!
And unfortunately Screen Change didn't work for me i even doubt if magnetic sensor is a part of screen assembly

The only thing left for me right now is to remove the screw! Everything else has failed
BTW i did tell those stupids at the service centre that a simple screw change will do as it's getting magnetized from magnetic sensor but still they couldn't help me with the issue.
What if my issue never gets resolved ? Ain't i entitled for a exchange of phone ?

Bro if you had "searched", there was no need of this thread. Its the 10th or the 20th of the same kind.
Plus if you want to exchange it and still something like this happens then?
Its not that an issue. Your phone is just 2 months old you cant even root it. If you couldve, then any CM rom or an xposed module wouldve done wonders.

There few people tried diff roms but the issue couldn't be resolved. The screen blinking continues.
My phone has been ok for 1st one and a half months but one day after i came home suddenly this started... So it's not like i am surely going to get the issue in new piece

Well touchwiz based roms might have this problem.
There is a huge difference between CM roms and TW roms.
And also S view cover works only with TW based roms..so..blinking is a hard to digest fact on CM based roms.

Uhhh...he did not mention which roms..
CM does not have any provision for the sview cover so how can itthe screen flash :/
CM based roms and Custom Touchwiz roms are different!
Touchwiz is just like the samsung we are using having mostly samsung stuff and look and feel is just like of samsung.
CM based roms are pure android. They are very stable and have no such thing as samsung apps or samsung's stuff.
A CM based rom looks as if we are using nova launcher (if you just use the launcher from play store, youll get a feel of CM roms) but CM roms infact are lighter, faster and smoother as they are pure android.

This is hit or miss from what ive read, it either goes at boot every time as well as the chraging flap warning every time you unplug, or only once. If it bothers you enough there are a few xposed modules that will remove both the warnings, other than that im not sue of any stock way to get it to stop other than reseat your back cover.

S5 keeps freezing and rebooting!! :(

Hey guys I have a issue with my S5 keeps freezing and vibrating twice before rebooting constantly I have tries flashing stock firmware via odin, repartitioning, custom roms, updated modems and still it keeps doing it at random intervals.
The other day it ran for about 48 hours without freezing but I have no idea what I did or didnt do that caused it any help would be much appreciated.

Since you tried all software fixes you could think of, problem's in hardware. Try another battery and see then. If even then it reboots it's something far more important than the battery and you're screwed :| (have to give it to repair shop).

I had the same problem and fixed it by changing to a new battery. It seems that the older battery doesn't hold enough peak charge whenever the CPU tried to stay at 100%.
already tried changing batteries that did not work for me.
Time for the repair shop route.. Or if it cost to much to fix, you can find a good used or new for cheap on ebay or swappa.
