Hello!
Lately my S8 has had a mysterious issue to where the battery always reads as a low temperature and the phone, as such, refuses to charge and errors out to low temperature. Would the issue be the battery? Or is it a more board level issue? The phone, as it stands, functions perfectly fine and has no issues with anything else except charging. The phone also recognizes the charging cable fine. The phone is using the stock ROM, on OneUI 1.0 (I haven't had the time to root it yet)

Underneath the back glass is the wireless coil/ temp sensor. If it's not plugged in or damaged this will occur. If you've had your device apart for any reason check this. If you've dropped it it's still possible if this piece isn't the issue it's either in the port or deeper

I have attempted to charge it with the coil attached, without it attached, and with wireless charging. All have failed and gave the low temp error. The coil does indeed recognize that it needs to charge, however it errors out.

The temp sensor is built into the coil. It can be bad. I'd order the coil and try. They are separate parts so the wireless coil can still try to work but the temp sensor is stopping it. Seems to be a fairly common issue

Thanks! I've gone ahead and ordered a replacement coil. I will get back to you if this fixes the issue or not!
That or the stupid moisture sensor. Although that one would be more apparent despite its the most obnoxious and useless feature I have seen implemented into newer phones. I've had phones acquire a few drops of sweat or condensation in my car and that would prevent charging.
Replacing the wireless coil seems to have resolved the issue. It was kinda obvious considering I found damage to the previous coil.

As of last night my A500 will not charge. I left the device overnight and unfortunately now have Zero charge.
- My charger makes a noise, I think it always did, so I'm assuming the charger is OK.
Can anyone confirm that the chargers give off a kind of electrical buzz when working?
- I get no light at all on my A500. If the charger is OK I'm thinking something has gone within the tab, be that circuit or battery.
Any ideas or tips here?
- Sadly I do not have a multi-meter to test either the charger or the tab, no friends with a similar device, I've lost my proof or purchase (which is painful and rules out warranty), and am a bit stuck what to do.
Any ideas?
- I've heard/read that allowing the power to drop too low can cause a problem. Obviously Zero is bad in this case.
Can anyone confirm this rumour or suggest a fix?
- I did try entering recovery and resetting the battery stats - whether this made things worse or not is unclear - it certainly did not help.
ANY HELP OR IDEAS WELCOME (bear in mind that I have spent quite some time searching and trying other peoples' ideas already though.
Thanks,

Quit guessing and get the charger checked
In reply to myself and to help those with a similar issue.
Yes a charger my buzz when good OR bad. The trick to seeing whether it is working or not (aside from it charging the pad) is to see if it gets warm -- no warmth, probably broken.
As for measuring with a multimeter the trick is to insert a paper clip into the small hole in the plug and measure the voltage between the outer plug (negative) and the paperclip (linked to the positive). Few multimeters have pins that will fit inside the super tiny plug on the A500 charger so the paperclip is your way in - obviously be sure not to short circuit the thing!
There are many chargers available out there. In Australia Jay-Car and **** Smith both have perfect chargers, the correct type, voltage, amps etc, they even come with multiple pins -- sadly none fit the A500!
My solution was to go to Infinity who are a provider of Acer spare parts. They have the correct charger and are easy to deal with BUT -- It's not cheap! They want $40 for the charger and a further $30 for the little bit on the end that gives the plug its nationality. In most cases we do not need this though as we can reuse our old one, but hey, not cheap all the same.
Still, it works and I'd rather be ripped off than get the wrong thing and blow the mother board.
NOTE: if you do get a charger from anyone other than Acer or a supplier of theirs - be sure to match every detail of your current charger - especially polarity.
I had problems with charging on my A500. When I plugged in the charger the power button would turn orange for a few seconds and then start flashing white.
I took the back cover off and found that the wire to the centre pin of the power connector on the tablet had almost broken off. I touched it lightly and it came away. Re-soldering the wire fixed the problem, it now charges as expected.
After fixing it I measured the charge current. It starts at a small value for a few seconds and then jumps to full charge rate. It seems there was enough of a connection to handle the small current but as soon as it switched to full charge current the voltage drop across the remains of the connection was too much and charging stopped.
Charging problem
I too just experienced the no charging problem. I looked up how to open up the tablet and tried to trouble shoot the problem myself. My problem turned out to be a very easy fix. The Posative lead on the back of the charger port had come loose, a simple touch of the soldering iron and its fixed. I thought since I had it open I might as well go ahead and change the battery too since it was 4 years old. Its an old tablet and time to turn it into a hand me down for a lucky niece or nephew
So yesterday, my old car's voltage regulator went haywire, and blew the car's main fuses after a couple of seconds.
I was charging my N4 during this incident with a cigarette lighter thingy and was holding aprox. 10% batttery charge.
The N4 is now 100% unresponsive. No amount of pressing any key combination for any amount of time does anything at all.
I have also tried charging it with a generic USB charger for a couple of hours, to no effect.
After that, I tried charging it with my computer's USB3 port for a couple of hours. This warmed up the phone a bit on the back, so it seems the ingoing current is doing something in there.
I am not getting a red LED indicator as most other people seem to be getting.
i fear something important was simply fried inside the phone, but I don't want to give up yet!
- Does anyone have any ideas what else I could try out?
- Are there maybe some small fuses inside the N4 that might be burned due to the voltage spike? Could I maybe replace or bridge them?
- could replacing the battery maybe revive the phone? If so, how could I test if getting a replacement battery will be worth it? Maybe temporarily wiring a compatible voltage to board?

Cool! I must have missed that the USB charging stuff is on a seperate board when i stepped through the N4 teardown!
Do you know if wireless charging goes through this board, too, or would it be using a separate circuit - i.e. should I head over to a friend's and test if I get SOME reaction from the phone when wirelessly charging?
Also: what worries me is that, as i mentioned, the phone's back is getting quite warm when charging it via USB3, so I am afraid that the charge is actually getting to the battery (vs. being stopped at a burnt fuse)
Hi. My phone got wet in my jacket pocket while riding my motorbike. It was probably wet for an hour or so before I got home and started attending to it. Obviously as it was in my pocket it didn't get submerged or anything, but i still found water residue inside. I took it apart, submerged the motherboard in isopropyl alcohol for a couple of hours and then left it to dry. Today it is booting up however I have noticed a couple of problems.
The phone will not start up unless it is connected to a power source when I try to start it. It will stay on if i unplug it.
It won't charge. First time I booted it it said 41%. As soon as I restarted it had dropped to 17% and is now falling even when plugged in. It does claim to be charging when connected however.
The front camera looks like one of those face-morphing apps (Is there's water around the lens or something?).
It also feels quite hot around the top of the phone when it isn't doing anything.
The loud speaker is not working (fine, I'm guessing that's just a case of swapping it out).
Could the first two just be the battery or some sort of issue with the USB interface? Any ideas how to fix these issues? Thanks!
Clean your usb port. I sometimes clean it with 99% alcohol and a toothbrush when I got some moister damage.
When you charge it, check battery stats and see if it says that it's usb connected.
If so, then you might need to flash a custom kernel (I used Ktoonz for it) and raise the charging stream true usb.
Because your usb port got wet, it thinks you are charging true usb. When charging true usb it will charge way slower. It's als probably the cause for your phone getting hot for no reason.

I will try that now! Any idea why it won't start unless connected? I've just not a new battery, no change on that issue.
EDIT: It's now starting fine. I'm waiting for a replacement USB connector to hopefully fix the charging issues. It's still getting hot when it's just sitting on the table and the battery is draining at light speed.

Good to hear it's booting again. From my experience these issues are temporarily and will disappear over time. The kernel and changing the charging speed fixed the same issues for me. I'm now running my normal kernel without any tweaks. So you might try it before swapping the connector. But that's up to you.

I had already ordered the bits and they were only cheap so went ahead and swapped them out. New USB connector flex and new speaker. Frustratingly I still have no sound. It's charging fine but the battery is still dropping off a cliff (like half an hour from fully charged) and it's still getting hot. I even gave the motherboard and connectors a good clean with high purity alcohol and some cotton swabs. Could the board have suffered permanent damage potentially?
Strangely, none of the water indicator stickers have triggered and it's still in warranty so if worst comes to worst I guess I can go down that avenue.
I have been using my Galaxy S5 with an OEM Wireless Charging Cover and Nokia Qi plate for many months now without any issues.
Recently, I installed an iOttie car mount that supports Wireless Charging. When using this car mount, I noticed that the Camera would not turn on. I get a popup error message that says the camera failed or that it can not connect to the camera. I then tested the camera while charging on my Nokia Qi plate and got the same error. The error occurs both with Samsung and Android camera apps.
I also made some other observations ...
-> If the back Camera is already running and I place the camera on the charging plate, it continues to operate.
-> If front facing camera was last used and the camera app was closed, after placing the phone of the charging plate, if I start the camera app it starts fine with an operating front camera but as soon as I switch to back camera, the error occurs
Based on these observations, it looks like the back camera is having issues initializing when the phone is being wirelessly charged. I would have never caught this issue because one would not try to the back camera when the phone is lying flat on a wireless plate but with the car mount, I tried to use the camera from within Waze app and when it did not work, it lead me to this entire discovery process. Did anyone else experience this issue? On one hand, I am hoping it not just my camera but on the other hand, if it is working fine for others, I will try to get a replacement.
You're not alone. I have the AT&T S5 and it does the same thing. Which really sucks as I tried to use it as a car cam to record bad driving habits and I can't. With the S5, wireless charging is the way to go so you don't have to keep opening and closing the charging connector flap. It is very annoying to me. Basically I believe the strong electromagnetic field generated by the charger coil is affecting the electronics of the camera. It's probably one place that is not properly shielded. I doubt you'll be able to find a wireless charger that doesn't interfere with the camera.

I'm on TELUS in Canada and have had the same problem. Has anyone determined if it's a software problem? I've been tempted to flash my phone to Cyanogenmod just because of this issue. It's a royal PITA and totally negates the reason I went with wireless charging in the first place.
Thanks,
Dan
I noticed the same issue when I tried using Autoboy Blackbox dash cam app and even Android Camera app while the device was charging wirelessly in iOttie wireless mount charger.
The workaround is to start the app before placing the device into the mount.
So there's lots of questions about bad battery life but haven't found my issue in searches - altho I suspect my issue is a factor for many to some degree.
N4 took a 4' to drop to concrete. Screen cracked. Replaced screen w/no problems. Ran fine for a while on stock 4.4.4. Lollipop comes OTA practically zero day and since the N4 isn't my primary phone I upgrade to play around. Shortly after 5.0, the battery drains and shuts the phone off. I charge it overnight, pull it off, battery is dead, phone shuts down. Will stay on and operate fine on wireless charger but powers down if not connected. Pop off the back again to make sure battery connector is snug and reassemble. Now I've got red light of death. Get Google logo and can boot to recovery options but it just cycles. Disassemble again and ultimately find that the battery pins from the mainboard and their little black housing have come off at some point. Try to solder it back on but there's chips on the back side and there's just no room to get the solder on and pins reconnected. Not w/my skills anyway.
My main question is, has anyone successfully reconnected that annoying mofo? Thinking about skipping the connectors and just soldering wire straight from the battery to the board. I don't see anything in that connector that would be a problem if absent, but any warnings I should know about? Other workarounds?
This is not mission critical, just principle/spite.
Repaired?

So were you ever able to get the connector solder back on? I think mine break because it was to hot when I was removing the battery. My nexus 4 shutdown on me, my battery was expanded. I was wondering why my screen was being pushed out. I wonder if Android 5.0.1 is causing phone to run to hot. Never did this with Android 4.4.4. Hope the connector can be fixed. Maybe I take it to a solder shop.

Not yet. I pulled the connector back off and cleaned everything up. I found that even very small gauge solder is too sloppy for the 4 small connections. Not to mention there's chips on the back side so you can't linger too long with heat. So my plan is to try again with some conductive ink and/or gel. If that doesn't work I'm just going to use wires to bridge the battery right to the board. Haven't had time to work on it but I'll follow up here when I do.
Did you get a replacement battery? Lithium batteries can swell because of overcharging. There are definitely more than a few N4 owners who had the same issue. A replacement battery won't solve that problem but it could be more tolerant of it, for a while - and depending on if it was "user error" or a fault in the phone's overcharging protection circuitry. Don't go to the trouble of having someone solder the connector back on with the old battery.
