"Why won't my Samsung Galaxy Tab 2 charge?"に関する回答Hi I Have the same Problem with Red X on top of the Battery Logo while charging my Samsung Tab 2 and managed to fix it by brushing the charging port using old toothbrush and 70% Isoprophil alcohol. procedures: 1. Get an old tooth brush 2. Put small amount Alcohol on the toothbrush, enough to make the brush wet. 3. Brush the Charging terminal of the Tablet. 4. Let the Alcohol evaporate for 1-2 minutes. 5. Use 5.2V 2.0A output Charger to charge the Tablet. It will works Fine at this moment. Good Luck!
