Answer to: Why won't my Samsung Galaxy Tab 2 charge?The Evil Red-X. I had it too. When I got my tab2 it only came with the cable. No charger. I was using a charger that had two output ports in it that I use for my phone. It worked for a couple months and then I started getting the red X. I found a different charger, and tried that. Still the Red X. Powered down/up, pluged it in the other charger, and the Evil X is gone. It is now charging at a good rate. It hss gained 10% in the last 10 min. I'm guessing the charger I was pluged into didn't have the needed Amp output. Next time at Wally World I'll pick up a bigger Amp rated Charger. Life is Good!
