Who else did that happen to?
Except from the two incidents in the XDA forum, I haven't seen any complaints here. Only users that are worried from reading the XDA thread.
No issues here. Been using the aero cooler too with zero issues. They would have to be isolated incidents.
I use my phone in mostly dusty conditions, lots of powder debris accumulates on the phone but NOT getting inside. Probably 2 of the reported units have issues!
I have got dust accumulated in my front camera now. Already created a post about it.
