dude. he was being snarky because he is ignorant of the way expansion and contraction, dropping your phone, turning on and off your phone, etc. etc. damage the solid state components.
He's just ignorant and flipped off a sarcastic comment without thinking. I've done the same thing myself on other subjects.
It seems dumb and like solid state devices should be impervious to damage.
But run them hot, run them through a lot of on/off cycles or cool/hot cycles and they are damaged and have a lower MTBF.
My god, reading the entire thread, I can't believe anyone took him seriously.
What does he need to do, put it in green text?
Look, for an easier way to find info on this subject google for router antenna's. They have the same problem (solid state but they degrade fairly quickly) and there are a lot more pages exploring why this is true.
My samsung has been hot to the touch many times (so over 100 degrees but probably less than 110- but probably over 110 inside) and heat is a leading cause for solid state parts of routers to go bad.
