i drop my DHD and its wifi dead

yesterday i dropped my DHD, and i realized the wifi stop working. when i turn on the wifi at settings, it just said "error", and wont detect mac address.
thingkng it just rom acting abnormally, i just reflashed over, aaand.. it still the same. so i factory reset, and it still the same. so i came with a conclusion that the wifi hardware must be broken, so i gave a try to 'knock' it and it works!
so after a small knock again my wifi dead again..
i wonder if it possible to nudge the wifi module, but i dont know where the module located,
the service centre said, they had to replace the main board and cost $145, duh!
anybody had tried to work with wifi antenae?

happened to me two days ago

Check to make sure your battery cover is on properly and not loose. I'm pretty sure that is the wifi antenna.

i'm not sure the battery cap has anything to do with this, but i'm pretty sure the battery cap was snap properly.
yeah, i hope someone had the clue how to nudge the antena,

The wifi antenna sits in the battery door, it's the little metal clip you can see in the door when taking out the battery.
You can try to fix yours if it's broken, or buy a new one on Ebay.
Hope it helped.

It happened the same to me, I repalced the battery cover and still no WIFI.
I tried using an APK named "FXR WIFI Fix and rescue" it fixed it, but after a day it was unable to connect again.
Looks like it's time to change my dear DHD

Duh, is it so hard to try for yourselves before giving an useless advice?
I just tried wifi with removed battery cover and it's scanning without giving any error.
gampangingats, if you are using Sabsa, it's still possible that this is a ROM issue, happened to me a couple of times, but system restart (full) always fixed it.

Right. This is a royal mess here, with everyone giving different ideas.
First ensure that both covers (battery door & bottom SIM/SD Card cover).
Then try a rock stable ROM (BlackICE, or something CM7 based is always good)
Then try the rooted stock ROM (search for it, its here somewhere)
Report back once you've done all that..
If not, go to the Ace Think Tank (in my signature) and post there. Resident HW expert Glevitan can help you out)

Charging paused. Battery temperature too high...?!

Hey there,
This issue started yesterday...I went to plug my S3 (SGH-T999V from Videotron) into the 5V charger and I go this message "Charging paused. Battery temperature too high.". I was like...uh..say what? I hadn't used it for anything else but watching a video (not even HD). After fiddling around unplugging and plugging back it finally charged.
But tonight, same thing, except it just won't let me charge! SetCPU showed battery temp at 80 degrees C (176F)!!! Mind you, I have the phone in a big case (Trident Kraken) but still, I removed the case and opened up the phone's back and it wasn't hot at all!!!
I waited an hour and then tried again. After a minute, same thing. Checked the temp, it was a 51.9C. I left the back opened and touched the battery, everywhere but especially near the contacts and it was fine...not hot at all!
I have stock ROM, stock kernel, but rooted. Of course, no overclock. I merely use SetCPU to put a clock speed limiter while the screen is off.
Anybody here has a clue about what could be going on?!?
Thanks!

At this point I'd say it could be one of two things. Software got corrupted and a factory reset will fix it, or the temperature sensor went bad and it's replacement time.
I'd try the reset and see how it fares. Typically this fixes 90% of problems (as ironic as that is, because we all flamed customer support at one time or another because that was their answer to every problem. And usually still is lol)

That's pretty much what I thought...
For the record I had tried a simple powercycle and it had no effect. However, I powered the phone off for an hour and just rebooted it and now it charges fine...go figure. I guess if it keeps happening I'll do a factory reset but that sucks as I would have about 60 apps to reinstall. I guess I could use Titanium Backup but then again wouldn't it backup the possible crap that's causing this issue? What about purging the dalvik cache perhaps?
Damn it. As I was typing this (after an increase of 4% in battery charge) it did it again...!!!

I just thought of another possibility or two
Bad charger.. or bad battery
Both can cause this I'm sure. Maybe even more likely. The battery could be bad, maybe the sensor is inside it. Sounds logical to me

I had turned the phone off after my last post and just turned it on to try charging via PC USB. Well, only a minute battery temp is at 60.3C (140.5F)! So I'm ruling the charger out.
As for the battery...well, I don't know if the sensor is inside or if it's inside the phone and just interprets data sent by the battery itself. It might as well be in the battery if the NFC chip is inside...
Anybody would know if wiping the dalvik cache could potentially help with this issue?

Never hurts to try!

this would be my guess

Well I went to a Videotron store and discussed with one of the agents there about the tests that were done, etc. I quickly gained his trust as, ahem, I actually work for the company as a commercial tech support agent...
I asked him to pull out the battery from his floor demo, which he reluctantly agreed to after asking the manager and we proceeded to test the other battery. Well, guess what? Same issue. Now, as per company policy I had to do a factory reset; tried again after that and again, guess what?
Issue persists.
So we proceeded to exchange the phone.
Neither I or him or the manager ever encountered this issue with any customer...I've googled this and looked all over XDA and never found any reference to a faulty battery sensor...!
One thing's for sure, the sensor is NOT located on the battery itself. By elimination, it's on the phone itself.

Wow that is crazy man. Glad you got it resolved! Least we know if someone else has a similar issue it may be replacement time.
Sent from a galaxy far away!

I'm going through this same exact issue right now. Bought a new battery and the problem is still there.

At the store you used a different charger/cable right? Have you tried completely wiping the phone? Which root method did you use?
Oh and THANK YOU for being detailed about the ROM, kernel, etc. It's impossible to help someone without knowing everything.

Went to the AT&T store and the problem was reproduced with no problem. They then directed me across the street to the service department. Went there and the lady couldn't reproduce the problem at all with the battery they had on hand. So now I'm being sent a new battery by mail to try out before replacing the phone. Hopefully a new OEM battery will cure my issue, but I'm not holding my breath. Thankfully the replacement battery I bought off Amazon came with a charger so I can charge and then swap batteries as needed until the OEM one arrives.

Wow this is interesting, as it is only the second case (mine included) that I'm aware of. And I had searched ALOT...!
Can you confirm that you have a T999 or T999V and if you were able to use any app that gives you actual temperature readings (such as setcpu for example)? If yes, what temperatures were you getting?
The battery sensor seems to be in the phone itself so unfortunately you'll have to get a replacement. Factory resetting the phone will have no effect.

software problem
Hi, this is a software problem try to use original rom and check re-partition on Odin ... i have the same problem with G70 Samsung Galaxy Player 5
I can't use custom rom because of this problem... my g70 work with cm11 normaly but the software have something wrong.. finally ... prohibiting charge the battery

Sorry for bumping this thread but I have the same problem, could I possibly buy a t999 or i747 board and just drop it in? Unlocked of course. Or can I replace said bad sensor with another, I have an old i9300 board lying around.

The i9300 is a very different device so I wouldn't try using its components. If you have a T999 or I747 then yes you can use either board. No other variant will fit right though.

Samsung battery too high problem fixed
Change charger adapter. Check voltage similarly. Or just don't use the 3.7v adapter at all

hi, i have samsung tab p3100 , its says battery temperature too high ,what will be the solution ?

I'm on my second battery now, first warped and died.
I'm now getting the battery temp too high issue, even though the phone seems cool to the touch.
I'm bypassing it by *charging my phone in the freezer*.
Not ideal, but I suspect it's a phone issue and not a battery issue as I tried a 3rd battery I had access to it it still happened.

NFC problems

I have a 3500mAh extended battery that I bought off Amazon. I forgot the brand name lol but I don't think it matters. Problem is that my NFC chip has stopped working with this battery. I tried using Google wallet at a vending machine that it always used to work, and now it just sits there and shows the wave graphic as it's loading, and never competes the connection.
I'm not sure if I damaged the antenna somehow or if it's possible that the antenna is now dead, because it used to work a couple of days ago and now, nothing. I haven't tried using android beam with another phone yet, or testing it with the stock battery as I'm not home (I'll try those later) but any thoughts are welcome.

does the battery say it has NFC? if not, it will never work
the antenna is in the batteries and without that, NFC will never work.

Funny, mine started doing that after the latest update. It took the .53 left on my google card ok, but I can't get it to charge any of my cards. And I thought it was just me but maybe not.

I'm pretty sure the battery has NFC. The amazon listing said it did, and it was actually working until a couple days ago (probably the latest update)

Just tested it with my girlfriends GSII, and I can easily send links, youtube videos, maps etc through NFC/Android beam both from my phone and to my phone. So my guess is it's Google Wallet.

[Q] Can't enable NFC AT ALL

OK I have Verizon Galaxy Nexus and for some strange reason. My NFC is entirely disabled. I am running full stock rom, locked bootloader.
I had the Google Wallet app installed when they first opened it. I used it mostly for the loyalty cards function but I decided today to try the NFC. Well I opened the program and it started saying the NFC was disabled. I never disabled it because I use it for other things (Mostly for my GPS in my car. I have a tag that enables the GPS and opens a Car Home app that i have automatically.) Going to the settings it shows the NFC option with the checkmark. but it's greyed out. I can't re-enable it.
So I figure I might've burned out the antenna on the battery. Nope. Switching the batteries to a spare that I have yield's a similar result. Namely that I can attempt to check the checkbox. But if I do it just grey's out and won't check the box.
What the heck is going on!?

do you have the official samsung batteries?

Absolutely. I don't use off branded batteries. I've had problems with them in the past with thrid party batteries on other phones.
So yes. I have 2 Samsung official batteries. I primarily use the Extended battery in my phone. I do have a standard battery which is the spare that I alluded to about testing to make sure the NFC antenna from the Extended wasn't shot.

Here's a screen shot of what the option looks like for those of you wondering.
It looks like this when I start the phone. But when I try to go through settings from the wallet app. It shows up clickable, but when I check it. It just sits there and does nothing. I've even set it to try to use it while the phone is prevented from sleeping for 35 minutes. Nothing happened!

Something is screwed up there. I have a non-NFC compatible battery but I can check or uncheck the box. Might have to do a factory reset.

nfc problem

I need to have nfc on for a personal device i'm using. However my leather case holds my contactless bank cards in the front of the case and when you fold it back to look at the screen this triggers it again .. please see screenshot. How can I turn it off for the cards ?

Hi i can see your using freestyle libre for the s9 also.
Ok facing some issues whereas as my battery power level goes down, its harder to scan the sensor. I'm on stock rom and kernal.
Makes it really inappropriate at times when i cant scan my sugar level as battery is low. Dod you face this? Is so What kernal/rom did you use if you managed to correct the issue

Hi! I've the same issue with NFC stop working when battery level drops below about 70%. Very frustrating (and a bit dangerous too for us with diabetes and Freestyle Libre).
Any suggestion to solve this would be much appreciated!

I've not managed to solve it. I just carry around a power bank now so can plug it on charge. As soon as it's on charge the nfc works again.
Hope Samsung resolves it soon. Must be a nfc power saving feacture

Facing same issue since month and seems to become more and more unstable. Any update on that topic? Hope it will be fixed at least with Android 9.0.

Hello, I have a samsung s9 + and I have the same problem as you. The NFC does not work below 70% battery

The same thing happens to me, I'm from Argentina, I have a stock rom, and it's more or less the 73% of the battery that the NFC stops working, do you know something if Samsung said something about it?
Tks.

i tried something else now. When you have your phone on charge, nfc works without problem (Under 70%)
when you pull the cable off, stops working.
Manufacturing date is http://prntscr.com/m0z97n

Hi People,
I have the same problem with NFC with lower battery levels and Freestyle Libre. I haven't upgraded to Android 9 yet but I am considering. Maybe there it'll be better. However NFC for payment works even with 1% battery level, no problems there. So there is something more sinister at work here.
Keeping my fingers crossed for a solution
Cheers!

Guys, when battery drops at 15%, NFC works again. LOL?
Anyway, i was on repair center and i told them everything, they check my device and waiting for replacement in 4-5 days..
So, GO and do the same.

Maybe at 15% battery saver turns on, which disables something that is stopping NFC working

I don't use it but have tested it and it worked fine with any %

Hi, having same issue here. Samsung replaed first S9+ ad now i'm having issues with my second S9+. Problem gets worse. Comes a time when it will not work at all no matter what its battery level. Running Android 9. Looks like a hardware problem as my LG G4 works fine (always have) and my Motorola 5s+ works like a charm. Its a Samsung problem. Anyone have a workaround? I have a facebook group for diabetics and am telling other libre users not to buy Samsung products.

Evening all anyone get nfc working? I'm on One Ui S9 not rooted and trying to read & write some NFC Tags but not getting any luck tried a mates S7 edge and that seems to work fine. Any ideas
