Anyone having USB connect issues?

Sometimes my phone will not charge when connected to the wall or my computer. The problem usually goes away on it's own, but when I need to charge I generally need to charge.
Sometimes I cannot access my phone via USB on PC either.

Only with data to and from the computer. No charging issues at all.

I've never had issues when plugged in to computer (USB). I frequently have issues when plugging into wall charger, but I think I have a bad cable. Phone will recognize charger connect, sit for a second, and lose the connection. Charging stops while cable is in. I bought a cheap cable on-line for the wall charger. I guess you get what you pay for....!

I have issues with usb connnect to computer since flashing cm6 8/13 nightly. Will not charge or mount usb.
Restoring back to 8/11 seems to fix issue but can't seem to get any newer nightlys to work or rc2.

Kind of sounds like a loose connector. I bought some micro USB cables from monoprice and the size of the connector was just a tad smaller than the plug for the phone. So if the cable wasn't plugged in and propped up in a certain way, the phone wouldn't charge. I just bought some new cables from monoprice (the ferite core ones) and problem solved.
I guess when this happens to you, wiggle the cable a little and then hold it for a few seconds at a certain angle and see if it starts charging... if it does then you know you need a new cable.

I was having similar issues and with my sd card permission issues I simply uninstalled my usb drivers and my removable disc drivers for the phone on the computer I think there was like 3 sets and haven't had an issue since.

Does Replacing the usb connector on t989 require soldering?

I received the phone and everything was great except i couldnt charge or connect to my computer because the phone didnt show that it ws connected at all (The battery icon remained the same), by mistake I found out that if I tilt up the cable, the phone will recognize it and charge as everything was normal. If I look closely and compare this usb port with other mini usb ports from other devices in the house I noticed it was tilted a bit down. So I put a sliver of duct tape and used it as a shim and put it between the male end of the usb port and the phone case itself, well it seems to work but Im afraid that it wont work for long. Anyway, to the meat of the question. I found some usb mini connectors on ebay for the t989 and when I have looked at the teardown I see that its attached to the motherboard as it was just plugged in, but then at the same time I see two solder points on the mobo as well. I don't know a dam thing about soldering other than what a soldered are looks like. Has anybody had any experience in removing the usb connector on this phone? Or just knows by looking at it how it is attached.
Thanks

Well before you do anything...it's micro usb Ports that you want

Can you link me to the tear down? I've been looking for one. And as posted before they are micro not mini USB ports. Also, I've noticed the horrible connectivity oon all my devices with micro USB ports. Even my brothers brand new optimus q from straight talk has this problem.

Have you tried other USB cables? I have the same problem with my stock USB cable too and thought there might be something wrong with my phone, but then I tried a different USB cable and it held on well.

This was my experience as well. Try other cables before you swap out your phone! :good:

The same with my cable. I guess they did it on purpose, that whenever your phone is 'tugged' the usb cable will be released instead of your movement being violently restricted by the force of the cable, which may cause you to drop your phone.
Any way, i bought a 3rd party flat USB cable which length exceeds 3 - 4 times the original cable , and it fits tightly in my phone's USB port. So i believe it is cable related.

I have the same problem, I guess it's just the one they sent. Oh well.
I did buy another cable, however I noticed that charging becomes extremely slow with it. I'm hoping to be able to find a better one that can support the higher charge needed for the phone, in the meantime I'll be leaving the phone down while charging I guess.

+1 same thing for me too. I was so worried thought it was a problem with the charging port but it seems the problem is with the charger cable. Using other cable is no issues.

Obviously it pops out very easy. I'm on my 3rd Samsung Micro USB cable, all are same.
But then I've tried my friends Galaxy Ace cable and it was fine. So you just buy a different Micro USB cable which will have same 2A output like stock one.

I. too, was worried when i first got the fone.... but it's the stock cable... tried another cable from another brand/manufacturer and it fits perfect.

I seem to be quite lucky. My stock cable fits nice and snug. I can even dangle the phone upside down holding only the cable and it wont come out unless I swing it or tug it harder lol

If you compare the stock cable with other cables you'll see that the plug on the stock cable is usually shorter than other cables by a millimetre or 2 so the little prongs on the plug probably arent grabbing onto the slots of the phone

Mine 2. I just stick blue tack on it

Yup, same here. I find the cable that came with my wife's Kindle is the best fit - needs a real pull to detach it!

Microusb cord falls out of port

Hello everyone,
This is my 2nd note II. My first device had a few problems and now this one seems to have a loose charger port. Also, when I connect this device to my tv via microusb, the tv screen flickers (could be an indicator of a faulty micro usb port). Has anyone had the problem of their charger wire falling out of the microusb port? What did you do to fix it? If you sent it to samsung did they return the device in working condition without any dings or scratches?
Thanks im adv

Mine was perfect for the first few weeks, but eventually got a bit loose so I replaced the USB cable which did the trick. Ive heard of other cases where the usb ports became loose, but not to the point of it falling off on its own.

hey i did try the usb wire that came with my samsung media dock... its a bit more snug, but it came off randomly after a while. my samsung otg usb cable fits great... the thing that concerns me is that sometimes when i connect my device to my media dock (uses the microusb port) which connects my phone to my tv, the screen on the tv flickers. this could be an indication of a faulty microusb port... but heres the confusing thing, ive tried transferring files to and from my computer via microusb and it works fine, so that would be an indication of a working usb port.
from what you have heard or read, was the consensus a problem with the usb port or the wire?
thanks

Yes, the wire was the culprit based on my reading.
Better have your phone checked. Im sure it's well within Samsung's warranty period

Ironically the best cable i use is a blackberry one, excellent secure fit

Problems with USB connection

I had been somewhat unlucky and while charging my beloved FLO something went puf (literally). After that I don't have any USB connectivity. Charging my N7 works (very slowly), but no USB OTG or USB ADB. OK Fine and dandy if I wouldn't be total idiot and wipe system while trying to install new ROM before transferring ROM image to internal storage.
Now I have FLO paper clip able to go to TWRP but can't install nothing. As far I understand there's no way to enable wifi in TWRP.
Any ideas what would needed to be replaced to make my FLO work again so I can put some ROM on it and make it work again.
I'm not sure if USB daughter board would suffice and solve my problem. Any suggestions?

Either the USB port developed "dry joints" or the wide silver cable (LCM) needs to be re-seated on both connectors.
Disconnect the battery before fixing LCM cable. Here is advice on USB port repair.
Replacing the daughterboard PCB should be the last resort because it is unlikely that the touch function will work 100%. It would work if we had access to the touch calibration software - the problems are described here https://forum.xda-developers.com/ne...rivers-to-calibrate-touch-screen-usb-t3334898

I doubt re-seating would help or cleaning USB port, since it was something electrical happening with that *puf*. If my memory serves me right there was a smell of burnt electronics. I doubt that some shortage disconnected any cables.

Sounds like you need a new charging port and board. Easy to fit but difficult to get hold of one. Maybe purchase a broken Flo on eBay and extract the charging port board

Even tho charging works? The only problem is data part of USB connection. USB OTG will not work neither will it connect to a PC for file transfer/adb. But if connected to PC or plug device charges. I believe it will not charge past 80 or 90%.
