I'll start us off. I recently had a problem with a Samsung Galaxy phone were it wouldn't stay connected to a secure wifi network. Would drop the signal about every 30 seconds and then reconnect, drop, ad nauseam. I tried everything and I mean everthing to fix it and nothing worked. Verizon store said there was nothing wrong with the phone hardware and it must be a software issue. Samsung must have screwed something up etc. No official explanation of why this was happening to my phone and others. I finally gave up and just used my capped (slow >_<) mobile data sparingly to keep apps up to date, place a to-go order, and started looking for a new phone. Then about a week ago out of the blue my wifi started working again! I suspect they ninja fixed it in an app update.
