I also posted this in the OTA Update Problems thread, but I'm not really sure that it is update related. If I leave my Verizon S4 on the (factory) charger overnight, it is soft-bricked in the morning (with red LED glowing) and I have to pull the battery to get it going again. This started (I think) after the update (yes, I did a factory reset) and all is well if I only charge enough during the day to get to 100% capacity and then pull the cord out. It's almost like the phone doesn't recognize that it's at 100% charge, and keeps going until some sort of overcharge protection kicks in and shuts it down. Anyone else? Thoughts? Warranty return in my future?
