TL;DR version: Three chargers I own cause the exposed metal part of my phone's body to light up a contact tester. One of the chargers causes a tangible shock. I'm not sure what is wrong.
I bought a new phone today, the Asus Zenfone 2. Until this evening, I had a plastic-bodied Sony Xperia SL, and as a charger, I've been using a Nextech charger happily over the past year or so, which has two outputs - 1A and 2.1A.
When charging my new Asus Zenfone 2 with the Nextech adapter, I felt a small but definite shock when I touched the small metal rim around the phone's volume buttons. A contact tester also lit up when touching that rim. When charging the same phone, but instead with the supplied Asus charger (2A output), the tester still lights up, but somewhat less brightly, and upon daring myself to touch again, I didn't feel a definite shock.
I then tested the same adaptors on my old Sony phone (which doesn't have exposed metal parts, but I connected my VSonic earphone's metal Neutrik plug into the headphone jack and tested the plug), the same results occur, both chargers cause the tester to light up, but the Nextech one noticeably brighter. Finally, I tried an old HCL adapter (0.5A) with both phones, which caused the tester to light up, too. I stopped touching any metal connected to the phones at this point, because I'm terrified of electrical shocks.
Now both phones do not cause the tester to light up while charging via my mother's Samsung adaptor (0.7A) or my old Sony adapter (0.85A).
My knowledge of electrical issues is very poor, and something is clearly wrong with either three of these chargers, or the electrical connections in my house, or the phones.
Can the knowledgeable people here please help me diagnose what's going wrong, and what I should do? My mostly electrically-ignorant mind first thought my new Asus phone is leaking electricity through the exposed metal part, but on realising that my earphone plug also lit the tester up when connected to my previous phone, I stopped panicking as much.
What is wrong here, and what should I do? Is my new phone 100% all right?
Is the phone supposed to allow current to leak to the metal part of the body, or is that some defect? And does this entire situation just mean the Nextech charger is at fault?
Hi, thank you for using XDA Assist. You should ask in your device specific forum if this is common for your device. From your other posts I see you know where it is but just in case, http://forum.xda-developers.com/zenfone2

I am looking into purchasing a Magnetic USB C charger adapter like the ones in the links below.
has anyone had any exposure to using these on their honor 8 or other phones?
is it a waste of my money or a good investment to preserve the charger port?
Magnetic Charger
IMO, waste of money, especially since Type C appears to be a more robust port than it's micro predecessor was. Also the cable may not handle voltage regulation properly which would result in a fried device.

Good point there on the voltage issues. I'm also a little concerned on how it will function with a case on it as well.
This device seems to be built very tough​.
I've had several Samsung devices in the past few years and every one of them had charger port weakness.
There are a few cons with cable such as those
1-lower charging rate
2-might not fit case cutout
3-finicky connection-it breaks away easily which is good cuz it a safety feature but attaching it is not that easy.
My experience with wsken xmini. Currently using it for tablets only as its safer for my kids. Wsken have a new rounded design that supposedly easier to connect, but still waiting for discount b4 purchasing.
I'm using exactly the same one. I really like but it this cable isn't a data cable. But I'm satisfied with the product
How are these possibly being looked at as a waste of money? Neighbor's kid running through your house and tripping over your charging cable ripping it out of the bottom of your phone leaving your phone safely still remaining on top of the table rather than crashing to the hardwood floor sounds a lot better than your phone crashing to the floor/wall.
Our phone are light enough that they will drag before it disconnects. I use it cause my niece usually yanks the tablet while it is charging.
I can not charge my phone due to the charging port not working does anyone know how to fix it or know somewhere where that I can buy a replacement?
aliexpress.com should still have them. the clone gionee e8 on there may also have the right ones but without a vibrate motor. did it myself fairly easily. have to remove the screws, take the 3 cover panels off as they overlap each other and then the vibrate motor is glued to the frame, pry it off carefully, remove the daughterboard and put in the new one which probably wont have a vibrate motor. those wires are too small for me to feel ok with soldering so i have mine without vibrate capability.

I had same problem nothing would charge battery, finding anyone to fix USB port was not happening it was like a hell especially a tech called me on Sat afternoon said he'll fix it drop it off by 4 pic up by 6:30 pm I asked if he had the charging port he said yes it's an easy fix.
I didn't feel like this was a good move only because of warranty I would have repaired it but it was a weekend no one at Blu Corp.& I needed my phone after returning to phone store I waited for someone to come out so I could pay and leave, the look on the guy's face I knew something happened as he tells me the tech couldn't fix it, so I asked why did he call me to drop my phone off if couldn't do it. He said he had the part and it's an easy fix..1 month later after battery warranty expired I opened it up and the charging port fell to the floor that dude resoldered all the tracks off the board he screwed it up so bad no one wanted to fix it. But I decided to find a way to resolve this problem that everyone has been going through and since I couldn't salvage my phone, I researched the wireless devices I called Qi Corp. Talked to person with best knowledge of their products, called Blu Corp asked if wireless devices worked on their phones using receiver lady said no. Turns out they never tried I was so bent over what happened and hearing more stories of people like yourself I found away to charge that phone I bought the Qi ( Chee) receiver (B) and bought the wireless charger that has a USB type connection a fast charger type and regular as if wall plug..It worked I love the charger the receiver I leave connected in charging port and using the gel type case it's like a thin coat enough to charge the battery and my current Blu Pure is not my old phone repaired I only paid $130.00 barley used made sure the battery could be charged and it's working perfectly...I leave receiver connected so whatever damaged the charging port wasn't going to do it on this phone...
I have told many Companies that wireless receiver and chargers work BLU was the only Company that wasn't thrilled about it...
Make sure you get it in writing if you find a tech to help fix your phone..GOOD LUCK
Has anyone had this problem? I woke up this morning and I couldn't unplug my phone. It finally came lose, but after examination I notice the port was messed up. My phone now only charges if the cable is turned a certain way. Flip it over and it won't change. I was using a Belkin charger from Walmart. Any ideas on where to start with this?
I forgot to mention that something obviously melted. I was able to get some melted plastic out of it.
For future reference do not use third party chargers unless you are 200% sure it meets the proper voltage specifications for your phone and has reviews for your phone. There is really nothing you can do to fix this aside from ripping the entire phone apart and replacing the port manually or requesting an RMA from Google support. Due to the nature of the problem I feel as though they would probably accept the request. Good luck
I'm going on 12-13 years avoiding Belkin anything like the plague.
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.
