for several months, I had to find the proper positioning of cable to recharge my galaxy note until I could no longer recharge. I hesitated between an external battery charger or the card. I chose this card and I do not regret it. 2 important things: make sure the version of the card (0.8 or 1.0) and see the video on the internet to disassemble his galaxy note. For less than a tenner, I have a functional phone.
