Hello I have a very big issue with my phone..
3 days ago I left my charger at work, so when my phone completely discharged to 0%, I had to charge it overnight with a non-fast charge adapter I had at home.. it took all the night to charge to about 70%.
Yesterday I brought back my original charger & cable and to my dismay fast charge isn't working anymore !!!! It is just like charging with the other adapter. Please help !
