Why my phone its just show the letter of “SAMSUNG” with white screen for 3 days over until now. I’d try to open the cover and put the battery again and again. But the phone still just like that. I’d try to charged it too but still same results. For 3 days my phones battery still ok and not turn off. So how can i do to turn on back as usual? I need my Note 2 back…
Have you tried another battery first of all?
