Hello, I just recently replaced the screen, back glass and battery in my friend's Nexus 4. Last night the charging port caught fire and fused the cable to the port. He had a look at the battery and that looks fine so I don't think that's the cause. Anyone have any ideas on what could have possibly caused it? Also would replacing the cable and usb fix it? The rest of the phone looks alright in the photos, or would it be likely to do it again? What would people recommend? Thank you.
I wouldn't safely say the battery is "fine" after such an accident. I'd replace it again, together with the port, and use a proper cable from now on... There are too many variables to take into account but I don't think that an original battery, for how exhausted and f*cked up it could be, would cause this havoc.
Ok, thanks for your help.
Replace your charging cable, do not use cheap chinese brands. If you charging directly from electric socket instead of computer usb etc, i would check if there is grounding available at power sources in your house.

My nexus 7 doesn't turn on or hold a charge. I plug it in to the wall and the charging icon will come on for five seconds, then the whole screen will turn off. If I unplug and plug the usb cable back in the same thing will happen.
Is there anyway to fix it or am I screwed?

How old is it? Is it old enough that the battery might be dead? Maybe the battery connection is simply loose or disconnected.
This shows you how to get to it : http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
(it's also the same guide you would follow if you wanted to buy a replacement battery and install it, otherwise if it's just the cable you can plug it back in and secure it).

It's less than a year old. It did suffer some water damage. I turned it off and put it in rice for a few days. Now I'm trying to turn it on and this is happening. I made sure there was a good connection with the battery. I also took it apart to make sure nothing was still wet and all the connections seemed good. I've also tried different cables and chargers. The original cable that came with it is damaged, but I've tried 3 other ones. Same result

Even if nothing was still wet now, there could be some corrosion in the internal parts, or some other parts could have simply been shorted and as a result would need to be serviced. If a new battery doesn't do the trick then it's probably something on the mainboard that has been shorted.

I will have to try a different battery. However, is there a way to get a replacement mainboard? I'm pretty sure the warranty is voided now.

eBay, or maybe the iFixit site might have parts, but usually when it comes down to needing a new mainboard, cost-wise you would just get a new one, and then sell parts off your broken one to make up for the difference.
Hey all,
I have a Galaxy Nexus which recently started to act up on his USB port saying it's constantly connecting /disconnecting to the charger with no cable present.
Device: Samsung Galaxy Nexus
Edition: Maguro GSM
OS: CM10.2 nightly + CM11 Alfa
Chargers: OEM, generic, battery & laptop
Cables: OEM & generic
Reproduceable: sometimes
This week I noticed my phone did not react immediately when I plugged it into the charger. Mostly after some fiddling (bending the cable away from the screen) it would start charging. After pulling the cable or removing the charger from the wall, it would generally take 5 to 10 sec for the phone to realize I pulled it- this used to be instantly.
Strangely, when the phone said it cannot charge it can be connected to a computer as Media Device without any problem. Charging only happens after the fiddling again.
Looking into BBS, it cannot give any stats because it says the device is connected constantly to a charger. Android original battery monitor stats are also a mess but it does not say I am connected always.
Every now and again the phone also starts making notifications as if he was constantly connecting and disconnecting - leading to frustrated looks of the people on my train...
Cleaned out the port - no success
Hit it on the train table - no success
Reset, battery pull, flash, different OS - no success
After this all I think it will be a hardware issue. Nothing seems bent and no pins seem to be sticking out. Removing the back and checking the mother board showed everything still intact and all connectors still in place.
I'm guessing now the micro USB connector of the phone has somewhere some corrosion or a pin out of place but not visible to the untrained eye.
Can someone shed some light please?
2 screenshots to show you what I mean.
No, I am not up for 9 hours and lost only 10%... Battery life has become horrible since this issue. It just thinks it's constantly hooked up to a power source and I think it's no longer power efficient because of this. I already disabled charge connection sound because it was driving me crazy ...
Please help if you know even half a solution. I can also post a photo of the connector but the problem is that there's not much to see there...
I think you have problem with charging circuit >>if you have solid knowledge in electronics you can simply replace it
replacing this port in attached pic will solve your problem .... otherwise you can fix your own port because I think one of your USB port pin are touching the ground chase of your motherbord
Thanks for the reply. Somewhat saw it coming I would have to replace something...
I already looked on some sites like ifixit to see what I could do but I thought to have seen that the Motherboard was in one big piece.
Could you please give me the website where you found this or the name /article code of this component?
Thank you

try to follow the steps on the link it is very helpful http://www.ifixit.com/Guide/Repairing+Samsung+Galaxy+Nexus+(Verizon+LTE)+Micro+USB+Charge+Port+%26+Main+Mic/9641
and you have nothing to do with the motherboard just take the old charging port and install the new one
Ordered a new part. Hopefully it'll work...
Hi so I bought the device about 3 months ago and it was awesome from the get go everything was great until today when i plugged in my device for charging. After a while i noticed it was charging very slowly so i instinctively disconnected and reconnected the type a usb cable from the charger. On reconnecting there was no indication of charging on my phone. I reconnected it one more time and nothing. So i took out my voltmeter and connected that in series. The moment i connected it it started to restart continuously. On off on off and i had to disconnect it to make it stop. I thought it might be a cable issue so i tried a micro usb cable with an adapter. Same result. Then i switched chargers, again same result. Whenever i disconnected the phone it would stop restarting. On one charger it did stay on but the voltage dropped to 3 volts and amps up to 2.3.
So i have concluded from above stated facts that the charging port/ board is kaput. If anyone has any suggestions on this please let me know.
After this i started to search for a replacement type c charging board for the redmi pro but i cant find any. Any help in finding one with international shipping would be appreciated.
Please leave Ur thoughts on my conclusion.
replace your usb c cable
Thx. But luckily i was able to repair it. Woohoo
Anyone know where to get a replacement usb charging pcb ?
was it a easy fix or did you replace the usb board?

Sorry for the late reply. I searched for the port on various websites when i had the issue but couldnt find anyone who sold redmi pro parts. Luckily however i found a seller on ALIEXPRESS who said that he did have it. He had asked me to pay using mi max charging board which was around 7 usd and then he would send The redmi pro charging board.
Sadly i cant find the seller who said this so i cant share the link here.
What u could do is go on aliexpress, find the largeat stores with the widest variety of xiaomi charging boards and ask them if they have it.

For me it realy was an easy fix and fast one too.
I was out of option at the time so what i thought of was that if i could find a 4 or 5 amp usb brick i could probably melt the shorted portion of the circuit. Ofcourse that in itself is dangerous because it could ruin the phone completely.
Anyways sadly i could not find any such power bricks. When i had almost lost all hope i thought of trying this out in my cars charger because car is already running on a DC system and is capable of providing alot of current to the usb charger, which is just a sort of regulated stepdown transformer. So hopefully that would provide the power i need. I started the car and then connected the phone. The moment i connected the phone to the charger the cars rpm lowered slightly for a second as if it were under stress and then went back to idle. AND MAGIC! It was fixed.
What it did was provide alot of current to the phone which heated and melted the shorted circuit. Since then ive had no issue with the phone.
It might be different for u though so i wouldnt recommend just doing what i did. If u have waranty claim that. If u r out of all options and u feel like ur phone is a dead piece of metal (like i did) then go ahead. But do not hold the phone in ur hand or anything while doing so because it can be dangerous in a number of ways. DC is much more unforgiving then AC.
Hope this helps.

Hi XDA,
After being a long time reader, it's time to ask you guys for some advice. My S7E still works great after 1.5 year of quite intensive usage. So far so good.
However, over the past couple of days, I've started to notice that my phone wasn't charged at all after putting it on the charger for 1-2 hours. The first 2 times I just thought that the cable just wasn't in properly, because after I reconnected the cable, it did charge. A few days later it just stopped charging at all. After testing it on a wireless charger of a coworker quickly, I knew the battery itself was fine. I tried a couple of cables, both new and old, but it wouldn't charge. Because I also used new cables, the cable wasn't the problem either.
So then, as a last resort, I tried to push the actual connection part (having the pins on it) within the port on the phone a bit inward. This so the pins in the port would better connect to the pins. And Boom! It started charging. So then I knew where my problem was. But now every time when it stops charging again, I have to do this over and over. This puts stress on the connector, and after repeating this process enough times, it will eventually break.
So here's my problem.. Because of how contracts are setup here, I can't open my phone up myself to simply replace the USB port (namely materials, but also certain skills). Also the repair service that is suppose to do the replacement, basically just sucks. They gave me a phone with a bend LCD back last time. I've fixed it myself afterwards back then. I don't want to send it there, except for screen repair.
So I'm looking for a way to either fix this connector permanently without opening my phone, or a specific type of cable focussed on bad connectors, or whatever might help me in this sitation.
Thanks for all your advices!
Wireless charging is ok. Its not as fast as usb but it gets the job done

Thanks, but that's only part of the problem. Let's say I need to connect my phone somewhere on the fly for whatever reason. Or are maybe on an airplane or something like that. I'll always need to bring toothpicks to fix the port, up until it breaks.
Mine s7 edge just stopped fast charging one day and PC doesn't recognize the phone anymore. It's still charging slow though.

just use airdroid. can trasnfer files wirelessly.
Well, let me clarify a bit... I know there are workarounds for the issue I'm describing. I could setup SMB and transfer files through that. The heck - I could write my own app, using my own "protocol". Charging can be fixed through wireless charging, thetering can be fixed using the hotspot, adb can also be done wirelessly, and terminal access I could get through an app. I could continue for a while here.
I actually want to fix this specific problem under the given circumstances. Not just dozens of workarounds for specific tasks. Let's say I **** up flashing, and need Odin to restore my device.
there isn't a way to "fix" this without removing a LOT of small, fiddly bits inside the phone. You certainly could get a micro-usb extension cable an leave it plugged into the phone all the time, or MAYBE use a Mophie Juice pack (a battery pack in a case that has a micro usb that plugs into phone and a new port that is on the edge of the case...
Other than that...SOL...
No sorry you can't, its nearly impossible to replace usb port without opening front panel and screen, and there is not a single percent chance to prevent screen from damage when opening front panel and glass, its simply doesn't designed to be opened. Go to samsung care center and give them the fee to replace usb port, if your screen got damaged during repair, they will replace it themselves.

Kinda was afraid of that, thanks for confirming. I like the idea of the case, hadn't thought of that. But the idea of the extension cable got me thinking. I think I'm gonna order some of those magnetic USB cables. They have a small adapter that barely sticks out. Then I simply need a few cables, for work, home and on the road. Because the adapter has no reason on move, it should be alright.
Thanks for your suggestions everyone!
Hi! I'm new here.
Yesterday I got an used S8 in great condition... but, except charging the device, all is ok. When I plug it in, it says charging, but Charging (USB), and not Charging (AC), so that's why it takes about 3-4h to charge the device fully. When I plug it in to my laptop, it does NOT get recognized. It's only charging with a current draw of ~500mA. The charging port itself does not look like if it is having some bent pins or it is not filled with dust etc.
What could be the problem?
I can't root the device as it is not getting connected with the PC, I was hoping that I could increase the current draw to at least 1,5A with a custom kernel, but I don't know if a kernel like this exists for the S8.
Appreciate any help. Thanks in advance.

So, I ordered a new charging port. I hope it will work. As Odin does not detect the device, it's sure that the charging port is busted.
I'd try cleaning the port even it doesn't look too bad. I've had similar issues many times in the past and it's always been crap built up in the charging port even if it doesn't look that bad.
I'd scrap out all the crap in it with something just to be sure. Dirt, dust and lint build up in the bottom of the charging port and get compacted in there from plugging in the USB all the time. I use a threading needle and use the thread eye end to clean mine but you have to be careful. Best to use a non-metal device if you can.

Well, I did change the charging port, even then it still refuses to "fast charge". I don't know what to do now.
