So I love the new phone but have noticed a few issues from time to time with it. 1. Can get extremely hot from use, or continue to stay hot after use (when the screen is off). 2. Random restarts for no apparent reason, unrelated to the heat issue. It has happened a few times and did it without me even having my hands on the device yesterday (it was sitting on my desk). 3. MicroSD card will randomly shut itself off and stop working, only way to use it again is to restart the device. Anyone else having these issues?
