Galaxy Watch user wakes up to an awful blister after apparent 'burn' overnight

(Image credit: Michael Hicks / Android Central) What you need to knowA Galaxy Watch 5 Pro user said they woke up to a painful blister and an apparent skin burn after the device overheated during the night.They say the watch won't turn on anymore, and other users say they've encountered similar problems with the Watch 5 and Watch Ultra 2.A Samsung Galaxy S24 user had quite the scar this year when their device "combusted" in South Korea.A Galaxy Watch user woke up to an unsightly (and painful) overnight battle scar. The report claims the watch "burned" them, leaving a terrible wound.The user reported the problem on the Galaxy Watch subreddit, stating, "​I wore my watch to bed, as I have done for the last 3 years, and woke up with a burn on my arm" (via Android Authority). They say the problem occurred with a Galaxy Watch 5 Pro. The watch was "fully charged" when they went to bed; however, it was "completely dead" once they woke up.Interestingly, a conversation in the thread mentioned a similar incident with a Galaxy Watch 5 six months after launch. One user reports that their significant other's Galaxy Watch 5 "...burned her in her sleep too. Not nearly as bad as OP's watch did. But did enough that she stopped wearing it altogether."Another report involved a Galaxy Watch 2. The user said, "I have the same issue, but not blisters yet." Many have mentioned contact dermatitis, but this issue (the one in the original post) doesn't match that. The publication mentioned this, too, but contact dermatitis would align more with a skin irritation/rash. The user here reports blistering.This is a scary issue, and one that certainly needs attention. The original post says that their Galaxy Watch 5 Pro won't turn on anymore. They're unsure if they should seek a replacement for the overheating issue.Devices so fire, they caught fire (Image credit: Nicholas Sutrich / Android Central)Android Central's TakeOur "smart" devices are scary, aren't they? These issues don't happen often, but when they do, it's jarring because you don't expect it to. Something happened internally for the user's Galaxy Watch 5 Pro. The rapid heating and severe battery drain definitely signal in my head that something's amiss. The problem is the "what." What went wrong, and since this has happened a few times before, what's Samsung prepared to do?The publication brought up something interesting: the usual safeguards to avoid severe overheating were seemingly nowhere to be found. Android Central has reached out to Samsung about this issue and will update this article when we hear back.While not a smartwatch, a Galaxy S24 user experienced a nightmare this year when their phone went up in flames. The problem occurred in South Korea. The user states their Galaxy S24 "combusted" under normal use. The phone had reportedly started to swell rapidly before it burst. Then, the flames consumed it. All the user states they were doing was browsing the internet, and it started to smoke.Get the latest news from Android Central, your trusted companion in the world of AndroidWhen the fire department arrived, it confirmed a "lithium battery ignition." The user was okay, receiving treatment for burns and smoke inhalation. Samsung also reached out quite quickly. Let's also not forget that a similar issue took place with a Galaxy S25 Plus, too.
