Why really I clearly original line, but fast charge can not be charged, the main reason is that you did not agree to his fast charge agreement when activating the mobile phone, all mobile phones have a fast charge agreement, after you agree he is fast charge, if you do not agree, he is in ordinary mode of charging, personal suggest that you can directly out of the charging agreement, directly click agree it will become fast charge, If it is not fast charging, this is the system has a loophole, and I personally recommend that you brush the machine.
