Galaxy s3 usb port not working?

Hey Everyone! I too have had much difficulty with the Galaxy S3's charging port, but I just found out why the phone won't charge and a quick solution for it without rigging the phone up with rubber bands or hair ties. The charging pins are only on the top of the port, and most every charger is not thick enough for the S3, so you simply slide a piece of paper under the bottom half of the port, then input your charger. The paper will keep it held up. This has been working for me and hopefully it does the same for all of you!

"On the s3 their are around 10 pins that need to be soldered to the board. If one of those has come up from the board from a jolt or drop, it could still charge but have charging issues so it most certainly could be the port needs replacing or resoldering. If you have tried a battery I would definitely try replacing the charging port. I found a company that does the s3 port repair. Here it is: S3 Charging Charging Port Repair Link

After cleaning the USB female port it still didn't work however did find out that by lifting the cable a few degrees while in the port a connection was made and charging was good. Eventually I made a plastic strip, the thickness of a business card and the width of the port ( very important), then stuck it under the USB tongue on the phone. When a cable is inserted into the phone it connects and charges every time. Have been dong this for 9 months now and waiting until contract is up to get an updated phone, 7 months to go!

You just need to hold down the power button and volume button at the same time for 30 seconds. My brother threw his away thinking it was broke. Mine wasn't charging so I called the customer hotline and they told me to hold those buttons and sure enough it came back on!!

kishore magar, if you need to replace the port, use this guide to get to it. Use a hot air rework station, or alike to unsolder the port from the board. Check for cracked solder prior to replacing it, a simple reflow of the solder on the part may be all that is needed. Hope this helps, good luck.

"90% of the time charging issues are caused by dirty pin connectors on the s3 port they get filled with crap and every time the charger is plugged in it compacts this dirt and makes things worse i have fixed all my friends s3's and all of them had the same problem

fix: 1 can of contact cleaner

spray a small amount inside phone port and then in charger plug insert and remove plug about 6 times respray both the plug and charger port and repeat this about 5 times and all is good if its not your phone port must be damaged and will need repairing by a technician.

i have had no problems doing this but still attempt at your own risk as i will not be held responsible for any broken phones"
