I left home this morning and noticed my phone (Moto G) was very hot. I pulled it out of my pocket to use and it said “Optimizing 73 of 197 apps” above a black screen. The phone was virtually useless at this point.
Why does it decide to do some rigorous operation like this with no forewarning? It completely blocked the functionality of the phone as it heated up to an excessive temperature. And, if it was doing some cell data operation, does that count against my quota? Grrrr!
