Loose connection using micro-usb connection lead

I've noticed that the connection using the micro usb cable is not snug, if I apply slight leverage to it the charge/connection is lost.
Im a bit dissapointed because I have certainly not pulled on the lead/dropped the device while attached or anything else that might have buggered the plug.
Is there any way I can make the connection snug again, or is this typical for all other devices too.
If this does turn into someting more problematic what are my steps to get it fixed, I brought this phone as an orange locked unwanted upgrade from ebay. fully boxed and sealed. (i.e. new)
Im a bit annoyed because the micro-usb plug is supposed to be more robust than the mini-usb. but to my eyes that not the case, and has proven to be not true either.

I have this issue too. Interested to see if it's a common flaw.

Same problem here. Just got it yesterday. The loose connection is very annoying in that you cannot be sure you left in a charging state unless you unlock it and check the screen. I wonder if it supposed to be that way?
After having posted this, I realize that the thread is not for my phone, a Samsung Captivate. I trusted Google search a little too much I guess. Interesting that the problem is the same.

Same here.
Xperia X10 with a loose connection that got much worse with time. I don't expect a fix for a hardware issue, but I am taking it back to the store for a replacement. The problem is that it has gotten so bad that I can't maintain a connection long enough to get my data!! Not pleased

me 3. another thread here t=689367 and here t=692242 (wont let me post full url as noob)
May have to return to T-mobile as its really annoying

I have the Captivate, and I had to exchange mine for one that did not do this.

Yep I started getting this problem a few days ago. Pissing me right off.

can someone tell me if the Samsung captivate and Xperia X10 both have micro-B USB ports also ?

Micro USB Sucks
I have the HTC Incredible and whenever its plugged into my PC you can tell by the audibles (and by HTC Sync failing 1/2 the time) that it keeps disconnecting and reconnecting - especially if you lift the phone or move the cable. So I was just as surprised to hear the MicroUSB was supposed to fix some of the wear and tear issues of MiniUSB - which is just untrue!!!

My HD2 has a loose connection
http://app1.appserver.dk:8080/RepairPictures/servlet/getPic?id=51371
<-- This is the chip. And HTC wont repair it. They say it's my own fault? :S

I've got this problem too with my desire and realised it's the cable. I got my desire on the release date (had it preordered) and the plug on the cable is smooth on all sides so it slips in and outu the phone easily. However, my girlfriend got a desire 2 weeks ago, and the micro-USB plug on her cable has two little spring loaded bumps on it, which gives it a positive "click" when it's plugged into the phone and it takes a lot more force to remove it.
Hence I stole her cable

My cappy too
This problem is happening, albeit not as seriously as some of yours, to my cappy now. I have had it for just under a year now. Looking back I could have been a little gentler with it...
Running Teamhacksung's ICS Build 9.

I've got the same issue - turns out that it's the cable more than anything, as when I plug the in-car charger one (a different cable) in, everything worked perfectly.

terrible design
Every device I or my wife has that is micro USB has charging issues. The design in a laboratory is supposed to get 10,000 cycles. But our experience is that a device after 6 months starts to have issues. Finally after a year about every device must be replace as the charging port is so loose that not even the highest quality cables will stay seated well enough to guarantee a charge or data connectivity. Very disappointed that EVERY phone uses this. Well other than Apple, which I may just have to go to since I cannot afford new phones constantly. The wireless companies KNOW it is a flaw in the design of the port also. Not a one of them will warranty the phone if the issue is the charging port. I am talking clean ports here also. No lint or anything.

I agree, micro USB is horribly unreliable across all brands. Too bad I absolutely loathe iOS, because I would consider getting an iPhone if I could run Android on it. Hopefully USB Type-C will be better.

5 data points and a question
First, additioanal data points:
I've had 2 different devices with micro usb connectors and both failed within 3 days of beginning to use them. I can't swear it was the female socket that was damaged but that was my impression. The prongs on the male connector were NOT flattened. I looked for that.
I had another device, a Nook Color I believe it was called, that had a usb charging/data connector that was their own slightly modified design of one of the usb standards. I can't swear whether it was a modified mini or a modified micro but I think it was a modified micro. Anyway the socket was a little deeper than the standard. The idea was that if you plugged in a standard male connector it worked the same way as a standard socket but if you plugged in the longer Nook male connector it went in deeper (I'm straining to refrain from low humor here), additional contacts came into play and it would charge faster. In the Nook case it was definitely the male connector that would break. I replaced the charger twice before the Nook failed for other reasons (I suspect a cat baptised it). If you search the net you'll find a lot of people had the same problem.
So in my case micro-usb is either 2 for 0 if you don't count the Nook, 3 for 0 if you count the Nook once, or maybe 5 for 1 if you count the Nook replacement chargers and charitably assume the last one would have worked for a while if the cat hadn't scented it.
I've NEVER had a problem with large, plain, standard, type A rectangular connectors. I think the idea that the mini is too big is one only Madison Avenue types could come up with. Even the standard type A isn't really too big. After all, how big is a thumb drive? I suspect it has more to do with making it a wee bit cheaper than making it smaller.
So yeah, micro-usb just plain sucks. Assuming Frank's posts in this thread at stack exchange:
electronics.stackexchange dotcom /questions/18552/why-was-mini-usb-deprecated-in-favor-of-micro-usb
aren't fraudulent, Nokia pressured the USB Implementers Forum to accept the micro standard, implicitly against the better judgement of some people involved. I'm therefore inclined to never buy a Nokia anything.
So much for the problem. I'm thinking about workarounds because there is a tablet I'd really like to use that charges through a female micro usb port. If I can't charge the battery it's useless. So I'd appreciate comments regarding the feasbility of these alternatives:
WORKAROUND # 1:
Carefully insert a male-micro-usb-X-female-standard-type-A adaptor into the device and glue them both to a piece of waterproofed luon (very light plywood) and then connect with a cable that has male standard full size rectangular type A connectors at BOTH ends. I've never had any problem with the standard full sized type A and they are easy to replace if I do. Though both adaptors and cables as described, are readily available, it is said that the maleXmale cables can damage equipment in some cases and I'm don't know enough to be sure this is not one of those cases.
WORKAROUND #2:
Alternately I could just glue the micro end of the kind of cable that comes with such devices to the luon and leave the rest of the cable dangling. Downside: Messy dangling cable. Upside: I KNOW it is safe.
Any thoughts on these workarounds would be appreciated.

HELP!! Phone not charging!

I don't know what happened. Phone was fine this morning. Went to work. Got out and my battery was around 30%. Plugged it into the charger and immediately noticed the batter wasnt giving me the charging animation. Unplugged, replugged. Nothing. Switched micro usb wires. Nothing. Connected to my PC.. NOTHING!! I did notice that when plugged in the phone became very laggy and unresponsive. So I thought maybe it was the rom/kernel. I was running BlackEdition ICS. Booted into CWM, backed up and flashed juggernaut. Still the same thing. No USB connection or charge detected and the phone becomes laggy and basically unuseable. Anyone got any ideas?

Just tried USB storage mounting through CWM and nothing. **** my life.

You have tried different cables? Or do you use the same cable in your car adapter and wall adapter?
Nvm.. Seen you said you switched cables...
Did you flash TDJs superwipe? If not, do that then flash a new ROM.

Dude I'm not even getting a charge animation while the phone is off. Seems like the port is completely dead but the things been in my pocxket all day. It's been funtioning properly except when the USB cable is plugged in. I noticed that it's not really lag... more like the touchscreen loses most of its touch detection. Anyone got any ideas?

Sounds like a bad cable to be honest, but if you tried different cables then it's hard to say.
AllGamer had the exact same issue and thought it was the USB port, but it was his cable.

WHOA. It literally JUST made the charging noise and immediately disconnected! I was reading your response as it happened. It just happened again!

Ok so I jiggled the wire inside the phone a bit and nothing. Took your lint advice... blew really hard in both the phone and wire. Oddly enough.. its working. **** you line. SAMSUNG Y U REMOVE SLIDING USB PORT DOARZ??????? One thing I definitely miss from my Epic 4g. Thank you guys. REally appreciate it. I was starting to think that the phone I just bought off someone on craigslist Thursday was already done with.

On my third GS2...
This may or may not be pertinent to your issue... I'm on my third (yes, third) Galaxy S2 T989 from T-Mobile. The first two stopped responding to USB input after three weeks or so. This was irrespective of which cable I used, which charger (the original OEM Samsung charger/cable as well) it was connected to or whether I "blew" into the USB port (old school Nintendo style).
Whether this issue is prevalent with this model is unknown, T-Mobile has been less than forthcoming with information about the handsets I returned. I've received no word from T-Mobile on my warranty-return handsets on what the issue was... but I told them in no uncertain terms that my next support call for this issue would be to another carrier (and a different handset, though I absolutely like the GS2).
Before I get flamed for not providing enough information or the troubleshooting steps I followed... I'll state that I'm an engineer (albeit mechanical) with a second degree in computer science and I took appropriate measures to ensure that the issue was the actual USB port on the handset. NOT the USB cable, NOT the charger, NOT the battery and NOT a software reporting issue. Aside from a lack of functionality, each handset was indistinguishable from brand new condition... no fluids, no drops, no abuse and no cheap USB cables used.
I could speculate on the cause for this issue, but with a device less than one month old, it's definitely a quality-control issue (whether for the USB connector source or Samsung if the part is sourced in-house). My current handset has lasted nearly five weeks without issue... fingers crossed.

I've yet to hear of this issue being widespread, and collectively my family has 3 of these devices. That doesn't mean it isn't a huge problem, but it's more likely you got unlucky. Some people have bad luck regarding electronics. My brother is a MechE too and has fried more laptops, monitors, hard drives, and cd drives than I can count.

Im glad it was just lint dude. Surprised that my idea was the issue.

[Q] Is there a fix for the usb port charging issue ?

First thing, sorry if this has been answered before. The thread search never works from my phones. It just disappears as soon as my keyboard appears.
Is there a way to fix the USB /charging port to keep it from being so touchy? I've tried new factory data /charge cable. I've tried expensive brand name cables. They all seem to work for a more th or two pretty well and then its back to charge/not charge sometimes without even touching the phone.
This has been the way with every Samsung phone I've owned and it is so aggravating because, as I'm trying to type or while playing a game it interrupts and causes lags and also the battery will die while I think its charging if I can't see a battery icon.
Other than sending both my phones in for new USB jacks/ports, is there something I can do? I'm pretty capable at fixing electronics if not too technical.

seem to be having bad luck with your ports i would suggest a new charger but im sure you've done that a plentiful of times or you just have really bad luck with phones thats stuff get an iphone JK!!! lol you stick to samsung chargers not no after market stuff right ? and does the cable feel securely tighten or loose when you plug it ? is this phone old new you could have a dirty port spray some air can in that port to clear debris

Hey, thanks for your reply.
I think this problem stems from me being on the phones a lot and I have the the charging /data cable in a lot to keep the battery up. With that, the constant mmovement of up and down from table /desk top, to ear,or car seat /center console to my pocket as im in and out of my car.
The cable always feels loose in the jack. Im sure the jack is stretched open. The chip that is inside, may be has worn and the edges of the board slightly filed down making a loose connection .
Anyways, Ive already had to start charging the battery directly. I've also got a replacement ordered. That's why I pay for insurance right?
So we can put this thread to bed. Thanks

I have the same problem... I'm on my 3rd Galaxy s2...... Phone can be on charger at 15% let it charge for a few hours and when I go back to check on it, it says 10% battery.. I've bought several chargers and batteries... TMobile just keeps sending me the same phone out.. I just got another one on the 13th... What could be the cause of this... Also the phone shuts off while charging... So many dropped calls.. I give up on this phone... What can I do..

Same problem here. The best luck is (oddly) using a computer (instead of a wall charger) and charging while the phone is off. And, the original Samsung charger block and USB are the least reliable of all I have tried. The microUSB end of the cable is slightly undersized. Note: removing the battery completely (while not connected by cable) for 10sec seems to improve the charging.
It has been a good phone but 3 years might be all it can handle. Xperia Z3 compact, here I come.

Stock Cable > Hard to Plug on the Charging Port of the Phone

I just purchased this unit. is it normal that the Stock Cable is Hard to Plug on the Charging Port of the Phone..
i need to try so many times before i can plug the charging cable to charging port of the phone before i can plug it successfully. i'm thinking of breaking the charging port if this is the case? Anyone who have the same concern? Thanks

I noticed this as well. hopefully if something gets broken its more likely to be the connector on the cable than the charging port. I have tried a few other cables as well and all are pretty difficult to insert.

Well the way I see it would you rather have it flop around and be loose, or have a night tight fit?
On a more serious note I had the same issue when I first recieved my F400S. After a week or so it got better, you can always try an older micro usb cable thats more broken in to avoid this issue.

when i first got the phone it was like what you've desribed. but after a while, it wasn't an issue anymore, i guess its a good sign that the phone is brand spanking new.

Same for me, hard To plug in ...

Hi,
I tilt the usb-connector up (just a bit) while plugging it in.
Greetz

It requires a downward angle tilting towards the device to insert.

Same for me, but once you're using qi charging and Wi-Fi file transfer, you'll hardly ever use the port.

got it! it was like virg** phone. haha..

wow same issue here.

Only way to get it in is by tilting the cable downward. Tried few cables, they are all doing the same thing. Exchange perhaps?

Tilting the cable to plug in seems to be the norm on pretty much every G3. I doubt exchanging it will help.
Once you've done it for a while, it should become pretty easy to do.

Tilting the cable and just dealing with it are fine, but what happens when you stay finding usb cables that don't want to charge your G3 properly? I have one (very nice) 10ft cable and my phone plays a game of connecting and disconnecting while trying to charge with this cord. This courts does not give me the same problems on other devices. However the G3 charges just fine on all my other cables. Not using this cable is an obvious answer but i worry that the problem could get worse and what if I start having problems with other chargers?

For now, the solution is to tilt the cord slightly downward (or upward, depending on your perspective) as the port is just sliiiiightly more flush with the opening. My advice is to get used to doing this. A broken charger port is really a PITA, so taking an extra 2 seconds to plug it in is the prudent choice. My dad gave me a lot of good advice when I was growing up, and one of the gems turns out to be "don't force things."
As mentioned, once we get some wireless charging back covers on a more accessible basis, we'll all just use wireless charging and never plug in again. Except in the car.

The cable from my old GS4 plugs in very very easily. I haven't tried charging with it tho. I use it mainly for usb mtp.
Posted from my LG-D850

Difficult at first. It did get better for me though. I too thought i had damaged it or that it had shipped that way. And I also thought I was just breaking it more each time I charged and contemplated exchanging LOL. Make sure cord is facing the right way first (im still trying to put it in upside down sometimes), then you do have to tilt it down a bit to get in initially and then it tilts slightly up before fully inserting. It was very diificult to do the first couple days. Day 5 and its way easy. Hope this has helped and put your mind at ease This is my first Android phone and i'm luvin it!

the past new phones i had. was always hard at first to plug it in.
just gotta lube it up

Any new updates on this? I guess tilting the cable a bit is working, but will it ever get to the point it will go straight in? It really appears that this is not a defect but a LG design for the port.
Sent from my LG G3

still the same.. still virgin after many charging cycle

I agree with what was previously stated, after a week with phone, I've become used to putting the cable in. I'm pleased with the tight fit as I've had devices where it feels loose and unsecured.

G4 Charge/USB port issues

I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)

Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.

I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.

I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.

I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?
