I've been using the tab for a long time so it's not a new one. I charged my tab after my tab turned off by itself, I think it is due to battery drop. I have charged it for one day now and it still hasn't turned on. My friend's tab 2 10 inch has experienced the same issue and it needs three days and even a week to turn on but I'm still worried is it the same with my tab? Can it really turn on after few days? Thanks!
