Seriously?
A competitive feature?
Lets think through that
- Did the Spen cause the explosion hmm no
- Did the exynos processor cause the explosion - erm nope happened to american snap dragon units
- Did the Superamoled screen cause the explosion? highly unlikely
- Did samsung smart stay, samsung pay cause the explosion - never heard that before
Both Android and IOS have safety cut off features both in hardware and software that protects battery ciruits, thermal throttling as an example. So something had to have happened in a catstrophic way for the battery explode, so actually Samsungs explanation makes the most sense.
I mean they recalled every single unit out there so they dont benefit from putting out further misinformation as they dont have anything to gain from it.
A serious error was made, the company took the option to recall every unit and replace, that enough especially for a korean company is an embarrassment for them so i pretty much believe the reason given
