Some Samsung Galaxy S III Units Are Reportedly Dying No, you shouldn’t freak out over this, but it is always good to be prepared for the worse! There’s a huge discussion going on both on Reddit and XDA Developers where owners of Samsung Galaxy S III devices discuss their bad luck: phones are dying for no reason. To be specific: “Tl;Dr – S3 mainboards dying for no reason, Samsung replacing mainboards for free, but no new hardware revision so it might just happen again“, says a post on Reddit. There are also other speculations too mentioning a probable fault with the phone’s NAND memory that is giving up. Okay, now that is bit scary, and I'm on my second SGS3 (as first one couldn't be made to work as it should) ............. even the current one went into boot loop twice for no apparent reasons so far.
