The Galaxy S III is probably the closestiPhone competitor to date and actually has a lot of people raving about it. Out the people I know who have Galaxy S III’s, I have heard mixed reviews, but nevertheless it is arguably the best Android handset available.
It looks like the Galaxy S III may have just encountered a setback however.Android Authority has reported thatGalaxy S III users are experiencing a strange glitch that forces your phone to turn off without reason and then it will not turn back on. Don’t just take Android Authority’s word for it  though, there is over 150 comments on a Reddit post and over 601 posts on a thread in the XDA-developer forum about the “Sudden death of the Galaxy S III.”
Are you sure about that Samsung?
A Reddit user by the name of Turtle Recall has summarized the problem on Reddit.
The XDA thread has 56 pages (so far) [at the time of his comment] of people whose mainboards have suddenly died. The devices seem to last between 150 and 200 days before failing. Samsung are replacing them under warranty whether or not people have rooted the devices or installed non-standardfirmware.
There’s speculation that the NAND is becoming corrupted and failing. Worryingly, Samsung are replacing the mainboards with the same revision so this may just be putting the problem off for another 6 months or so.
It happened to my S3 last week and I’ve never rooted or installed anything other than the official 3UK Samsung firmware, first ICS then JB. Samsung haven’t officially acknowledged that there’s an issue, but both the guy I spoke to in the authorised repair centre and the chap in the Samsung warranty call centre have said they’ve seen this issue a lot lately.
Tl;Dr – S3 mainboards dying for no reason, Samsung replacing mainboards for free, but no new hardware revision so it might just happen again.
At this time it is not known just how widespread this problem is, but by the sounds of all the attention both the Reddit post and forum thread are getting, it is safe to say it is not just an isolated issue affecting a few people.
The Galaxy S III is not the only phone to experience some problems. Other smartphones such as the iPhone have encountered hiccups such as AntennaGate and ScratchGate, but the sudden death of the phone is definitely at the top of the list.
