Samsung Galaxy S III owners have taken to Reddit and the XDA Developer Forums to complain that their Galaxy S III handsets are randomly dropping dead. It appears that the phone will not power up again after turning itself off, or after the screen goes blank. Here’s what one XDA forum user had to say:

I went to sleep in the night with my phone’s battery at around 29%. I just woke up and my phone’s home button wouldn’t respond. Then, the power button wouldn’t respond! I took the battery out and put it back in. It still wouldn’t respond! So, I plugged the charger in and then it showed me that it had begun charging. I turned the phone on and as soon as it reached the lock screen, it turned itself off. It did that twice more so I decided to let it rest. Now, it turns on. (>_>)

There are currently 64 pages of discussion, and it appears that it’s an issue related to the phone’s mainboard. Unfortunately, there isn’t a solution yet. Several people have reportedly sent their devices back to Samsung under warranty, however. We’ve reached out to Samsung for a comment and will update this post if we hear more.
