So I have a Samsung Galaxy s4 and it won't charge. This is on my replacement device. The exact same thing happened on my first s4. & I was wondering if there is anyway I could get a iPhone as a replacement device. Before it stopped charging, if the charger wasn't in there exactly right it wouldn't charge. So sometimes when I would wake up it wouldn't be charged because it moved. This also happened on my first device too. It would also freeze & crash all the time before it stopped charging.
