Yesterday, my phone had trouble charging via its power adaptor where it refuses to charge unless the phone is off, today, I can charge normally, however I noticed that I've lost the ability to view my internal storage.. because this will show up no matter which port I use on my computer and other computer and whichever cables I use..So far I have tried uninstalling driver via Device Manager and USBDeview, but still this problem reoccur when I plug in my phone...
