Some Samsung Galaxy S8/S8+ phones are turning on by themselves before shutting back off



Thanks to posts put up in the Samsung community and Reddit by some Galaxy S8/S8+ owners, we have learned that Sammy's current flagship model is having a mysterious issue. The problem starts when the phone is turned off either by pressing the power button, or by letting the display get timed out. The phone then powers itself back on for about ten seconds before shutting down once again.

Since this is taking place throughout the entire day, it results in the draining of the phone's battery. A video posted on YouTube by a Galaxy S8 owner whose handset carries this strange bug, shows the phone turning off and turning on again all by itself. This cycle takes place even with the phone inside a flip case, as you can tell by the video. It appears that this bug is affecting some Samsung Galaxy S8 and Samsung Galaxy S8+ models only. The Samsung Galaxy Note 8 does not appear to have this affliction.

Thus far, there has been no word from Samsung about this issue. Last week, the company had to deal with a new battery problem discovered on some Galaxy S8+ and  Galaxy Note 8 units. Certain models would not turn back on after the battery was drained down to 0%, shutting down the particular phone. The manufacturer said that it has received only a few complaints about this and said that it will need to input more data before it can come to any sort of conclusion about what is going on. Replacement phones are being offered on a case-by-case basis.

Easy solution, probably the same for the other ten users affected by this, this is breaking news.

Its probably an app notification setting causing it to wake.. I bet if you load the same apps on your new handset it'll do the same thing.. If the phone was turning on after a proper full power off, then shutting down again then I would call this a real issue..

luckily no issues with it on Note 8. Screen only comes on when it hits 100% charge

My wife's S8 has been doing this since we got it two months ago. We haven't noticed it during the day (not that it hasn't; we just haven't noticed it); we notice it at night, because it lights up the bedroom when it comes on. As it's our first Android phone, we thought we may have some setting wrong.

The device is not powering on and off as this poorly written article suggests. The screen turns on and off. Interesting to know what the cause is though. Never saw it on my s8 and am not seeing it on my Note8.

Since writing the above, I did a web search and found a "Screen turns on for seemingly no reason" thread with the S7E from March 2016 on an Android Central forum. So, it's not necessarily a new issue.

I have s7edge from day 1 of release. Nothing wrong here. Best battery of all my phones. Maybe some accesories like special cases (S view, S cover) with defectives tags? Check all the facts and numbers of incidents and then uou can say it is something wrong with all the line of phone. And ... Apple did by purpose throttle cpu without telling users.

My S7 Edge battery life was atrocious. The Note 8 (and the Note 7 and Note 5) destroyed it in battery life.

I've had issues with other phones I use to buy the flip case for. But each time it was the case itself. When the case was replaced, the problem went away. The case has some type of detection mechanism that is suppose to activate a feature of the phone, like the SView cover which I always bought Nd the see through one which activate AOD feature. Seems the S8 didn't have issues until the last update.

100% correct, I had a cheap knockoff case and it did the same, after replacing it everything was fine.

Alan is coming back. Orders from Apple are clear: find something bad about competitor to take away the spot on Apple fraud with cpu purpose throttle for saving a defective/low quality battery inside iphones that conduct to shut downs at 40% battery charge. And for this, you Alan, better take a look at your posted video and see that the phone is wearing a case with tag inside and the possibility that the case beeing defective is very large. To be journalist you have to ask the owner to conduct the test without case. If it is not repeating the bug you have to state that some Samsung cases it is posible beeing defective. You did what? What Apple order to you: be agresive by all means on Samsung, doesn't matter that you spell the truth or not. You are pathetic, man. Usually I stay away for commenting situations like this but it is to much of it from your part to be a soldier of Apple propaganda. Be sure I'm out from here because I can't trust articles on this site.

What? We have to talk Apple for a month?! We already knew what happened and what will happen to those batteries. That's so 2017, no ones talking about it anymore.

Of course not. But none of you have no issue talking about the Note 7 for several months even now you all bring if up. Why be hypocritical?

I don't think is it's the phone, I can get it's the case. Many 3 party flip covers are grunge. But I did have an issue with a Samsung SView cover for my S6 edge. Samsung sent me one in 2 days.

Seriously? is iPhonearena now going to post every single issue for Samsung devices regardless of how minor or how few phones are effected? They never usually post about this stuff like this and for good reason, it's of no interest to anyone, chances of this effecting you are tiny, probably better chances getting a win on the lottery. How much are Apple paying you?
