Samsung Galaxy S3 Units Crashing; Not Rebooting
Samsung Galaxy S III, best phone of the year is under a problem. According to XDA thread, Galaxy S3s are crashing and won’t rebooting without any reason. Started (thread) about month ago today various users are reporting this issue. The problem is with Mainboards as explained by Reddit user, TurtleRecall:
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-standard firmware.
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.
If similar issue happened to your phone and device passed away than don’t worry. As Samsung is doing the right thing by replacing them under the warranty, no questions asked.
