My Samsung galaxy tab 2 7.0 stopped charging today. As all the battery was drawn out so when I plugged for recharge it was continuously rebooting after showing one bar of battery. I was using the original cable that came with the tab few years back. I checked this thread and it appeared that the cable is bad and most of the people fixed it by changing the cable. So I decided to attempt cable clean up for any dust inside. I took my regular aftershave lotion and rinsed both sides (connector and USB) in the lotion. Then I used air pressure to dry it out. I reconnected after few hours and it worked just as new and my tab is now charging.
