Can Waze cause the cell phone to overheat even after being closed?
Waze definitely not just causes my Samsung S3 to get hot, but always causes the phone to heat up wildly until it crashes due to extreme overheating.  I can get a maximum of 30 minutes out of it before my phone overheats and dies.  It's the only app that I've ever seen do that.  Also, it uses more power than my phone charger can provide, so the battery level drops consistently even when plugged in to a charger that can provide 2.1 amps.  I've had to stop using Waze.  Too bad, as it seems like a nice app, but I can't run something that's going to destroy my phone.
