esterday I installed the newest os update to my galaxy s4. When I plugged it in shortly after it got really hot and went into cool down mode. I unplugged it but within hours battery was back down and now will not charge unless I turn it off. I'm using the factory supplied charger it came with. I had this same issue with a previous update and had to buy a new phone. Now the latest update ruined that one?! Why doesn't Samsung test the updates before rolling out? Is there a fix for this widespread problem? I'm not buying another phone!
