I used to go travel and left my adapter charger at home. I used the universal adapter to connect my phone with the Samsung charger to charge it. However it seemed like remained uncharged. So, it went dead for almost three days. After went home and I charged it, it seemed pretty weird as after fully charged, the display remained notified it as charging. Its sign still fully charged after awhile and went down after a short time, although it showed fully charged before. I couldn't turn it on unless DURING charging. And after a day or two, I can't even turn it on at anytime, as it showed the empty battery when I tried to turn it on. Although it was fully charged a moment before. Went to the repair center, they tried to change the battery but still can't make it work. Terribly stressed! Help me!
