I have a Moto G and 2 things are going on. 1 - i use it very little and my phone is pretty hot right now, I hope it won’t explode. 2 - is that the battery is not staying charged for an entire day, with very little usage. Any help?
There are many different reasons the phone could be heating up ranging from software conflicts to hardware failure.
A great place to start and an all-around quick fix is to try a Clearing the Cache operation. This is often recommended as a first step in troubleshooting android issues.
