I bought an Insignia (Best Buy private label) brand 30-pin USB cable to charge the Samsung tablet. I also used a 2A charger from Acer.
After one hour of charging, the tablet failed to boot properly. The splash screen appeared, disappeared, and was replaced by the animated charging icon in the middle of the screen.
I went into Recovery Mode (Power + Vol Down), cleared the cache partition and rebooted. The tablet behaves as expected, but the battery icon in the lower right has a red X through it.
The tablet may have been purchased originally in Europe. The language setting was set for French. The Android version is 4.1.2 and I believe this is the stock ROM. Updates were set to be installed automatically.
Do I have a dead battery or another issue which needs to be addressed?
