I have three different car power supplies here for the Galaxy. One, that came with the car dock from Samsung, and two similar ones that came from Amazon.
The Amazon ones got a fuse (1.2A) in them, the Samsung one not.
After a certain time (20 Minutes?) of use with my Galaxy the fuses burned. I replaced the fuse in one power supply with a 4A type: it burned too.
I replaced the fuse with solid metal: the spring, which makes the contact to (+) in the cigarette lighter was glowing hot, melted and broke finally so the contact was off!
The original power supply from Samsung didn't say anything, just stopped working, stinking.
Maybe my accu drains too much engery, because it is damaged? But then the thin cable to the SGS would melt....
The line power supply becomes quite warm while charging but charges the phone.
I see no reason for that although I have certain experience in electronics....
I cannot use my SGS in my car
Have you checked the car's electric system? What kind of a fuse is connected to the lighter in the car?
i'm using a cheap 2Amp car charger from DealExtreme and it works perfectly, most after market car chargers have fuses to protect your electrical system.
i'll suggest getting another car charger instead, probably the one you have is not made to the standards and it's causing some sort of short-circuit
As I wrote, I own three devices. Each one is bricked/burnt fuse. Among them there is one Samsung original car power supply that comes with the Samsung car dock.
The other two devices came from Amazon.....
My car is a two year old VW Touran.....I cannot imagine that its electrical system is the cause of my problems....
Even the galaxy works perfectly....no battery drain....everthing is allright...
If the electronics should be damaged somehow, the phone wouldn't work, I think.
I have no idea how to fix this problem...perhaps it needs more investigating by me.
Yust to be shure, that your car has nothing to do with it.....try chgarging in another car. I have no such problem with cheap charger i bought in petrol station.

From what you say, the only reason for the contact betwen cyg-lighter and charger wold be glowing red is an imperfect contact. Maybe you didn't push the charger all the way, or the lighter was dirty.
Yes this sounds reasonable. I'd tested the device the whole day in my car with and had had no issues....
I opened one device and found nothing that could be responsible for a short circuit. The whole thing must have to do with car's plug connection.
Testing will go further....
Anyone having issues with your touch screen when you are using it while it's chArging? Just wondering if i have a faulty device or are there others with the same problem

No my device does not have this issue when charging. I think this issue has something to do with the charger.
That's a grounding problem, had it with my SGSII try a different cable.
The sensation had an issue of touchscreen problems while charging. i went through 3 phones. The cause is the same cause as the wifi errors that people are having with the HOX. Bad connection from unibody(sensation) to board.. If we added aluminum foil or solder (just like the HOX wifi issue) it would fix the problem. On the sensation the problem got really bad to where you couldnt unlock the phone with the lockring. grounding issue. I hope the HOX isnt having that same issue and you just have a bum phone or better yet a bum cord or charger. let us know if its either
yeah happened alot on my s2, was due to usb cable or something
but works fine when im charging
It was the grounding issue, does this damage the phone? I have a wall outlet with USB ports so it might emit too much power

Every time this has happened it has been because of what the USB cable was plugged in to and not the cable itself. Try the charger it came with in a regular plug. If it doesn't work better then it is a phone problem.
This happens to me too. Charging from the laptop with an eBay (chinese) cable causes the touchscreen to be unresponsive.
Here's how to test: Open the Notes and draw a few lines very fast.
Here's the results:

No USB Charging
Here is a video of it happening to me on my skyrocket. It was because of the charger. Try a different cable, then a different wall adapter.

It is because of the charger...it's always recommended to use the charger that came with the phone eventhough they give us a tiny a$$ USB cable.

Yes, I have an issue - when the phone gets to 90%+ while charging, the screen becomes very unresponsive. The drags don't drag - instead the touches are registered as taps.
You can get an app like MultiTouch Test - and you will see, it's very clear to see when this happens.
My first One X device did not have this issue, so it's something specific to my current unit. Doesn't bother me much, since it only happens at 90%+ charge, while plugged in...

To me it doesn't happen all the time, sometimes it happens, sometimes it doesn't. Unplugging the cable and plugging it back in seems to temporarily fix the problem, if I leave it charging for a couple more minutes, I think the problem will come back, but again, unplugging/plugging it back, solves it temporarily. It's weird...
Oh, and all this to say that I observed this behavior while charging around 65%, not 90%. And I've only observed this while charging with AC power with the original cable and charger. The problem did not present itself (yet) while charging through USB.

I just had this happen with the stock charger from my old HTC One using it on my HTC One X. Along with touchscreen problems it got VERY hot located as you are looking at the camera side it got hot on the top right side near the camera. Dunno what that could be. Both chargers are rated at the same voltage and amperage, I dont get it

It's caused by electrical noise. The voltage supplied from your mains outlet is alternating current (typically 50/60hz in frequency). a usb charger has to do two things; firstly step down the voltage (110v/230v/240v down to 5v) and secondly rectify the alternating current into direct current (positive and negative). how it does this is by using a transformer which employs an iron core surrounded by copper windings, this generates a lot of rf (radio) which travels down the cables to the device as well as broadcasting a short distance through the air, a decent charger will use shielding as well as a few other pieces of circuitry which will neutralize the rf given off. In order to rectify the voltage the charger will use a variety of diodes and capitors, in a cheap Chinese charger they will typically use as little as 2 and possibly a generic chemical capacitor (similar to a small battery) these degrade over time and can get quite hot, fat and eventually burst - when you hear about chargers exploding or setting on fire it's usually because the capitors aren't up to the job. a Chinese charger may have all the quality control and certification stamps but most of them are forged, if you buy a charger for less than $10 this is what your likely to end up with. the outputted voltage may appear 5v on a multimeter but they are a very dirty output and can spike from 3v to 7v or even more the load on the charger increases. The dirty output interferes with the mechanism used on touch screen devices which also employ a type of capacitance to register where you are pressing on the screen. A decent charger will use solid state capitors and which should last a lifetime.
if the smartphone miss behaves whilst charging 90% of the time it's because of a faulty charging device (or one employing poor components). a decent charger may cost more $20 but they are significantly safer for both you and the device.
The problem with mains sockets with built in usb usually comes down to shielding, they will either have none or be earthed (which might sound like a good idea but in practise a lot of domestic devices will create leakage to earth causing more noise - alot of studio equipment will have a separate earth). These may not be as dangerous as cheap Chinese chargers but still undesirable.
If a original or good quality charger isn't available one of the best sources for charging a phone will actually be a desktop pc with a usb3 port. The whole pc is insulated in a nice metal case and there are a plefora of high quality components to create a stable clean power supply (a cpu voltage tolerance is usually measured to 2 decimal places of a volt which is pretty good).
Ditch the rubbish cheap chargers, you honestly get what you pay for and they aren't good for the long term health of the phone. If it hums or makes a high pitch noise whilst plugged in your playing with fire - literally. they aren't bothered if your phone dies in 6 months or bursts into flames so long as they get the $5 x 100,000 people who buy them (these things literally cost pennies for them to put together, even though the case might look the business inside they are nasty and as cheap as)

Very insightful. The worst part is that I have two original HTC chargers and they both emit the high pitched noise.

Some of the very small chargers might whistle a little, its called coil noise and isn't as bad as capacitors about to pop. The iron core hasn't been sufficiently dampened or glued into the case so it resonates when the ac passes through it, the pitch may change depending on the voltage (whether its a 230v or 110v power supply). It isn't unsafe but HTC should be doing a better job at checking the new chargers, over time most chargers will develop coil noise as glue tends to melt or degrade.
Very insightful video, you'll never buy a cheap charger again
https://www.youtube.com/watch?v=wi-b9k-0KfE&feature=youtube_gdata_player
The gist being the cheap chargers could very well set on fire and the USB could go live at mains voltage with no circuit protection, death traps spring to mind. Be careful what you buy.

Just wanna ask about my problem/trouble with my XZ3s magnetic charging port.
Since I bought my phone, I charge it through the micro usb port. Knowing that frequent opening of the flaps may lead to compromising the waterproofing of the device, I planned to utilize the magnetic charging port of the ZX3.
I bought a WSKEN Magnetic Charging Cable the other day. I tried it with my XZ3 and found it hard to use. I have to tilt it a bit on the side to make it work. At first I thought the problem was the WSKEN Magnetic Charging Cable. I went back to the store where I bought it from and asked for a replacement. After testing it, the problem was still the same.
Yesterday, I tried the WSKEN Magnetic Charging Cable I bought with my office mate's Z3 phone. It was a perfect fit and without any problems!
Today, I tried 2 different magnetic chargers and experienced the same. It needs to be tilted to work.
I find it very frustrating since this is only a 1-month old phone.
Now I went to a Sony expert friend and enlightened me that this is a real rare case in XZ3s that happens to very few XZ3 units. He showed me that by pressing beside the magnetic charging port makes it normal. He explained that there is a clearance with the contact points inside the unit. He advised me to bring it to Sony Service Center which I'm already decided to do.
Now, may I inquire on how much will it cost me for the repair of this kind of problem with my beloved XZ3?
I hope I receive a positive response.
Thank you.
I am having a similar issue. Magnetic charging port doesn't connect well with charging cable or dock, I have to wiggle it forever until it gets proper contact.. My wife's identical phone works well. It really pisses me off because I am forced to use the USB port to charge my phone most of the time. I'm not going to take it to service center though, not only it will most likely cost quite a bit to fix, I don't trust just any technician to put my phone back together properly maintaining water resistance. I've read some horror stories from one guy killing a bunch of phones right in service center because they were no longer water resistant.
I wish there was a simple fix for this issue without taking a phone apart...
Hi I bought 2 keyboard folio from eBay brand new but it is like it haves a faulty battery. When I try to pair it with the tablet through NFC I press yes on the "do you want to pair the Nexus keyboard" but after some seconds it fails. But when I put the keyboard to charge it works. After I pair the devices and use the keyboard when I unplug it it stops working straight away. So I was wondering if this happened to anyone else and if it is any key combinations to hard reset the keyboard or something like that?
More people having the same issue!!!!!!!!

I opened the keyboard and the battery seems to be dead because I tried to charge it with another charger and nothing was happening. On the keyboard I put another battery 400mah but still wasn't charging so I thing the board is faulty too. I will take a picture of the battery and upload it because I tried to find one but I couldn't.

Please upload any pictures you can, would be really helpful.
I was considering buying a simple small portable battery charger 1500-2200-4000~ and using it, but it would discharge too quickly, attempting to charge the faulty one in the folio. Also considered taking the folio battery/charging component and splicing in portable battery charger..
Another option I thought of, is using a male to male micro usb cable from the Nexus 9 to the folio.
I am using a generic micro usb charger works fine. I also bought a male to male micro usb cable attached to the Nexus 9 and folio, also works great. The keyboard hardly registers drawing any power.
Sorry for the late reply. That's the original battery of the keyboard which i tried to find but couldn't. The hard part is that it needs to be 1.5mm to 2mm of thickness Max so the keyboard top part can close normally. The other pictures is the modification I made replacing the battery but with a thicker one. It wasn't charging so that's why I came to the conclusion that it must be the board too that it is faulty. I connect the - and + cables from the charger to the exposed cables to charge the battery and that's it.

Hey... Just bought a brand new one with the same issue straight out of the box.
Have you tried measuring the original battery with a multimeter?
The battery protection circuits will sometimes protect the battery from undervoltage by not letting them charge any more as it potentially damages them...
One way to attempt to recover the batteries is to remove the protection PCB and charge them with a LiPo charger at super low amps till they get up to like 3.3v then letting the original charger and battery protection finish charging it... (Kinda dangerous if battery really is damaged)
These things sat on shelves for years.... I can't imagine the batteries didn't drain.
Edit: did you take the keyboard apart??? Lol... Is it glued together??
I took mine apart... This is not a reversible process lol... Checked battery voltage and sure enough... 0 volts.... There's no Li-Ion charger that will ever try to charge that battery as there is a risk of fire.
Looks like HTC cheaped out on the battery protection circuit and it didn't cut off the battery below 3.3v and let it get to 0v... Gonna have to try to recover the battery using my lab power supply to trickle charge it... My lipo charger complains and won't charge it at all.
I'm having the same problem. Just bought one of these on Amazon for $30 and was excited to use it. How did they charge $130 for this when it came out?? This is useless. I'm going to have to return this junk. Any solutions before I do?
The solution is easy.
I have effected this repair on multiples of the nexus 9 folio keyboard.
Someone said earlier that the charging circuit is bad in addition to the cell being at 0v. This is simply not true. For the charging circuit and the cell to both be bad you will have likely hit the lottery in a bad way, or shorted and caused damage yourself.
Truth is that as mentioned before their protection circuit on their $130 keyboard was not up to the task. I make the assumption also that they overpriced these so heavily they sat until their hardware choices became apparent by making them DOA after the cell's voltage fell too low.
Someone stated that opening the keyboard is irreversible, this is also untrue, it only requires a bit of skill and patience.
Take it for what it is, because I would never recommend someone to revive a cell that had been sitting below 3.2v, it's just unsafe, but this is what worked for me as I didn't feel like digging through china stock to find a matching cell.
The cell is at 0v, so the fix is simple, connect another similar chemistry (3.2v-4.2v) cell in parallel (between the protection circuit and the cell.) I just used and 18650 from a laptop battery. Let's call this a "jump start." Start the charging and disconnect the second cell. Red charge LED should remain solid and charge cell 1 to 4.2v and you are good to go.
As far as the details, we know that the cell is on the left side, so only heat and slice adhesive from just beyond the corner to the center, slide your tool under the cell to remove the adhesion from the main body and carefully slip the cell out far enough to get at the contacts in order to get between the protection circuit and the cell.
main points
1 DO NOT PUNCTURE THE CELL (ALUMINUM TEARS EASILY)
2 DO NOT DAMAGE THE RED AND BLACK LEADS FROM THE PROTECTION CIRCUIT TO THE MAIN BOARD
3 DO NOT PRY OPEN THE OUTSIDE CORNER NEXT TO THE CELL AS THIS CORNER IS MORE SUSCEPTIBLE TO DEFORMATION THAN OTHER AREAS
Probably best left to a skilled tech, but it can certainly be done.
The adhesive htc uses is much like hot glue, so after scraping the old glue out reseal and press with a hot glue gun (precision tip recommended,) easy peasy.
On a final note, shame on you htc (and google.)

I ordered another on off ebay, but i used the suggestion i thiunk i saw on here. I have a microusb OTG plugged into the nexus 9 and running a usb to the keyboard. it is supplying enough power to run he keyboard. also it does not seem top drain much power at all.
I'm typing this message on the folio keyboard. if the other keyboard folio has the same issue then i can at lease use this solution to use the folio.
now i need to order a shorter usb to microusb cord so i dont have to rubber band the cord and look sloppy when carrying it around

Nah, it's definitely a charging light. Doesn't blink when pairing but does when a USB charging lead is plugged in. Goes off after a couple of minutes, which confirms what we all know: the keyboard doesn't/won't charge.
Picked up one of these new from Ebay. It doesn't seem to want to charge and will only work when plugged in with charger. Anyway to get it working? Guess it's a return
I've been using magnetic cables for my Android phones for years. You put the magnetic USB adapter in the charging port of the phone and the USB cable connects magnetically to it. Makes it very easy to charge your phone while driving, keeps dust and dirt out of the charging port and decreasing the wear and tear on the port from constantly unplugging and plugging in a cable. However, when the USB adapter that stays inserted into the phones USB port is in there for a certain period of time, it seems like maybe around 5 to 8 hours, it triggers samsungs moisture/foreign object sensor and disables the charging port entirely and the only way to charge is by using a wireless charger. There are several ways to temporarily circumvent this but ultimately the sensor always gets triggered and the song and dance starts over and over again.
So that being said, has anyone figured out how to stopped this from happening without rooting? I love my magnetic charging cables and have invested a lot of money in them and I use them not just for my phone but for several other devices likes tablets and stuff because they can universally fit usb-c, micro, nano and thunderbolt with just one cable.
Thanks!

Did you try with another magnetic adaptor?
I have also been charging with a magnetic charger for many years, now even for the device I've been waiting for almost a month, I ordered brand new kits. I really hope there is no problem like what you described.
Of course I will also buy a wireless charger, but the convenience of using the magnetic one is indispensable for me.
Yeah I'm having the same issue with my magnetic charging cable. I haven't had the phone long enough to see how big of a problem its going to be, When i get the pop up i take the plug tip out for a while and it seems to go away.
Worse comes to worse if it starts to become a major hassle I'll just get a wireless charger hopefully someone will figure out a solid fix before it comes to that
Never knew something like this even existed... Can one leave the tip in the usb port permanently as a cover to protect it from dust/ debris when not using to charge it? It also seems like a great solution for protecting the USB port from the constant wear and tear of plugging/ unplugging into it..
Exactly.
For years I have been using this solution to charge with a magnetic charger and the magnetic adaptor from the cable stays in the phone until I replace the device with another.

Yes.
So I tried something that might have fixed it more permanently. See if this works for anyone.
1. When you have the moisture sensor/foreign object notification and you get the message pop-up stating the charging port has been disabled while trying to charge with a cable plugged in, keep the cable plugged into the phone.
2. Then, restart the phone by pressing and holding power and volume down button and selecting restart.
3. When the phone reboots you will notice that the phone is now charging properly. AND if you unplug and plug the cable there is no moisture notification anymore.
I've tested this for about 24 hours and this has been the longest time it's been without triggering the moisture notification. Normally it takes under 8 hours to trigger.
So if this works then you can keep your magnetic adapter inside the phones charging port indefinitely without getting that moisture notification. I have not tried removing and reinstalling the magnetic adapter which might reset the moisture trigger.
Pulling the adaptor and reinstalling it also seems to at least temporarily reset the moisture notice
I'm glad to find out that I'm not the only one with this trouble. I'm not sure what I did, if anything, to fix/workaround the issue, but I've not seen the moisture sensor trigger for almost 3 days now. (Knock on wood.)
Things I've tried:
Reboot while the charger is connected.
Clear data in the USBSettings system app.
Switch to a magnetic plug that hasn't been used before. (I had several that came with the cables that have remained in the box until now.)
After trying each of these at least twice the problem still occurred again later. Today I realized that it's been a few days since it happened. To clear the warning sometimes it takes a blast of compressed air into the port, sometimes it only takes removing the plug, waiting a moment for the notification to clear and then putting it back in.
BTW, for the curious who haven't seen these before, search for "NetDot Gen12" at Amazon. They are very convenient. This is the 3rd or 4th phone I've used them on, and I also use them on tablets and other devices with a USB charging port. The only issue I've seen besides the moisture sensor on the S22U is that there is a small area on the screen next to the magnet where it is a little less sensitive to the s-pen. It's so small and usually such a non-issue that I didn't realize that it was due to the magnet until recently.
Of course, now that I've mentioned that it's been a few days since the moisture sensor was tripped, it has now happened again and my 3 day streak has ended. :-(
I wonder if the true quality of these cables is being revealed through other means (bugs in hardware through environmental discharge or whatever). Could be something simple like ESD on the pins, crosstalk/interference. Either way it's reading a short to ground and doing its job by protecting the phone.
USB was never designed around these magnetic devices and aren't in spec. It's not a phone problem. It's a cable problem.
There's a comment here: https://us.community.samsung.com/t5...lse-moisture-debris-alert-issues/td-p/2204054 that suggests it may be a software issue, as the commenter states that he's started getting it on the Note 10+.

Out of all the Android phones I've used with a magnetic cable (which have been probably 5 from various manufacturers over the years) I've never seen this problem before until now. The last Samsung phone I used was an S7 and I do remember having some odd over heating warnings when charging but eventually that problem went away. I think this "foreign object" sensor is being triggered because the magnetic adapter is staying plugged into the usb-c port in the phone but not charging. Thus the sensor is being triggered. However, there seems to be the same pop-up notification message for "moisture detected" and "foreign object detected" since it covers both in the same message. So it is a little tedious to figure out if the moisture sensor is being triggered or the foreign object sensor is being triggered.
Could the cable be at fault? I highly doubt it at least in my experience. It's more realistic that Samsung has placed so many safety sensors on this phone that it's only a matter of time before one gets triggered. But magnetic cables have been around for years and Samsung knows this. So they knew by installing this foreign object sensor that it might break the use of magnetic cables. Which is sad because Apple has had magnetic charging cables for years in their laptops and recently their Apple phones use magsafe wireless chargers which is a magnet built into the phone.
I've also used magnetic chargers for years in my Android phones and tablets and I've never seen it adversely affect it in any way.
I'm having the same issues and I'm not using some cheap knock-off magnetic cable but one that has been on the market almost 3 years, is still available, comes with a 10yr warranty and supports up to QC4.0 on the mobile cable version (which I have) and is also available in a 100w PD version (ChargeASAP Uno cable). These moisture/debris alerts are the FIRST problem I have EVER had with this magnetic cable, and while I originally bought 3 sets (thinking they would wear out from daily use, I never even opened my 2nd & 3rd set until I started having issues with it in my S22 Ultra on day 1 and assumed it was coincidence that moving it from my previous S10+ to this phone exposed a weakness from wear and/or age. Unfortunately the brand new set had the exact same issue.
Now, in my case, I always wirelessly charge, except when I'm in my car using android auto daily (why I bought the magnetic cable) and the once a month or so I copy data to/from a PC. I am getting the moisture/debris alerts every couple hours or more when the magnetic adapter is in and it is HOURS before or after I actually used the magnetic cable (tip was inserted 24/7 until I got tired of this nightmare). On the weekends when I may not drive or sync for 24-48hrs, I've gotten the warning when the phone was just sitting on a table at the lock screen for an extended period in my house. My charge port is spotless without a speck of dust and this continued to happen with a brand new magnetic charging tip that was sealed in an anti-static bag before putting it in the phone. Honestly this MUST be an erroneous BS error and Samsung should address it.

"Mobile Device" 18w version (I have these): https://chargeasap.com/collections/usb-c-mobile-device-magnetic-cable
They also sell 100w versions geared toward laptops and/or PD Charging
Interesting thread. I never knew about the magnetic system. I do keep a usb-c plug in the port full time to keep out dirt and lint. Never had the moisture popup so far in a week with one inserted in my S22.

This is interesting. So you use just a plastic usb-c insert cover of sorts? Can you provide a link to the product?

There are other versions but these are the last ones I bought: https://www.amazon.com/gp/product/B085T5L9T6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
They don't last a long time if you are taking them out every night to charge with a cord. But now that I have wireless charging, they should be more permanent.
