About 3 months after I got my Galaxy S4 it started saying "Connect to original charger" and at the time it was connected to the original charger. So I switched chargers and that worked for a while.. then last night it said the same thing.. and it was connected tot he charger I have been using for the past 3 months. I switched to two different chargers and It finally started to charge and then stopped again. It died completely and when I tried to plug it in it vibrated but would not turn on. Then this morning I tried to plug it into the car charger and that worked and it is now charging plugged into my USB in my computer. I am concerned this is going to keep happening and I have heard of other Galaxy S$ owners having the same problem, where it says connect to original charger and you are connected to the original charger. I have insurance... Do I need to replace my phone?
