As of this morning, my S4 hasn't been turning on. I left it charging last night and this morning, even though it was plugged in, with the original charger that came with the phone, it is not doing anything. I took the batter out of the case, left it alone for a few minutes; blew on it; and then put it back in the casing and still nothing. It will not even show the batter picture while the phone charges. It just won't do anything. I'm worried because I really need my phone for my job and stuff like that. It is very important. I'm not sure what to do. Any help would be greatly appreciated.
