I tried charging my phone and it just won'charge. bought a new battery tried charging it and still didnt charge. so i went ahead and striped the wires on my charger and connected them to the positive and negative points on my phone and thats how it charges. but i cant take my phone out of my room because if i unpluge my charger it turns back off. what could the problem be? its not the battery and its not the charger.
