I have a problem with my S8. After locking my phone it randomly vibrates and turns screen back on asking to unlock (enter passcode or scan fingerprint). Sometimes this happens right after locking and other times after 5 seconds when my phone is already placed on the table. When I unlock the phone there is no notification. I can't seem to find out whats causing this. This is not always (but most of the time) happening though, its really random.

Checked internet. Checked Reddit. No apps enabled in accessibility. Smart Alert disabled.

Its driving me nuts, please help out.

EDIT: When removing passcode the phone unlocks itself to the lockscreen. Just happened after 15 seconds when laying flat on the table. Should I leave my house??? haha

EDIT2: Seems like the homebutton is registering presses. When 'Unlock with homebutton' is on it go's straight to the homescreen when above happens and when its off it turns on and just shows lockscreen. Really strange..

Actually, this is a HUGE issue IMO and abnormal behavior of the phone, which is subjet to return.
You should be straightforward in your decision or get used to the issue.

I'm tryning to say that I don't think this is a hardware issue because than it would be all the time, must be software related but can't seem to find out whats causing this.

S8 Unlock problem

Im having the same problem. I unlock using the pressure sensitive home button. After locking and unlocking 3 to 4 times the home button does not respond "only on the aod screen". Then suddenly it unlocks and when I lock the screen again the phone vibrates and unlocks the screen itself

Plz help me out

I'm having the same problem. Sensitivity changes randomly. Sometimes it doesn't seem to recognize presses and sometimes it recognizes them even when I'm not touching that area. All this happens when screen is locked. AOD disabled. Sensitivity to 2 (close to very sensitive)

Having exactly the same, however samsung technician was unable to replicate it for a whole day and they sent it back to me without any repair... Swap is also not an option as samsung will test phone on their side anyway and in case it's "good" they will send back same unit.
Issue is really random and sometimes it doesn't occure for over an hour. Then it starts vibrating and waking up after touching screen in top or middle area couple of times (screen off, AOD off, no case, no screen protector), multiple vibrations after pressing "home" button or delayed vibration.

Other reports are on reddit (pm me for link) or different xda thread forum.xda-developers.com/galaxy-s8/help/hard-press-home-issue-t3597004/page4

Anyone able to record his issue to compare with others?

I went to Samsung Premium Service and left my S8 (Exynos one) for 2 working days.
Sometimes when I press home button it vibrates once or with significant delay and then when you touch screen anywhere else (top, middle, edges) it vibrates again and wakes screen up. It looks like it cannot register/release pressure sensor correctly. Since they were not able to replicate this error they decided not to touch hardware at all, therefore just reflashed it and calibrated.
I'm getting this 2 or 3 times this every 15min, but it's hard to record, because when I start recording it's already working properly... Have you managed to record your issue to compare with other users having similar symptoms?

My pressure sensitive home button has a mind of its own like it works or sometimes doesn't register as a press then sometimes when I try press harder or softer it goes mad and registers lots of presses. Sometimes it just works properly though. Should I return it quick or is it just normal if the screen has to be cleaned or something?

I have same problem, i owe factory unlocked s8 created for caucasus region. my home button makes me crazy, even now when i was writing this, just picked my s8, i pressed hard on home button, on the screen off (I've enabled always on display) and no kind of vibration, than touched back button and it vibrated. So sometimes it vibrates 3-4 times when i hard press only one time, sometimes it's giving me very late vibration, sometimes i also think that i get notification and nothing is there. yesterday it gave me two vibration, during facebook scroll. i'm a big fan of samsung but, this s8 has too many hidden problems, bugs and luggs.

isn't it possible guys that in the next software update it will be solved?

Same problem here. I think there is another thread with this issue btw?

It could very well be a widespread issue but a lot of people might not even be aware of it because not everybody's using hard press preferring other ways to unlock/wake the phone.

U won't find out when it will miss vibration or any other bug or lugg. I'm testing and testing, even i pushing home button half an hour without resting and there were no kind of bug. I think that, than when there is no too much free ram and also when phone is hot, also U have many apps minimized and u lock the screen. And at once u push hard on home button. It will fail vibration and if you observe during screen unlock, animation will stuck. It's opening bit-by-bit. Looks like very low FPS. So this 3d touch failure makes phone work luggy.

P.S. sometimes phone is cold, with much free ram and same happens((.

Also when phone is locked for long time. When you press hard on home button on screen off (with always on display) it will miss the first pushing.

Sometimes if it fails vibration, it continues doing this for minutes, even phone restart will not solve the problem.

There is something wrong. This phone has ram managment problem, there is something strange. This device is a real rocket but it isn't well optimized.

I hope Samsung will fix this bugs in the next software update, otherwise i think i will go to iOS. Just i need smooth animations, smooth app open/close, without stucking. Without luggy, without bugs.

Whith this problems this really fantastic devise is nothing.

P.S. i'm a big fan of samsung. Have had many iphone, and thinking to return there.

Sorry for my english.

    ok, I just "lurked" this thread until now.
    I've a S8+ Midnight Black with some issues to the virtual home button. It's excessively sensitive, perfectly usable though. It's like if is always set to the maximum sensitive setting, so not a real big problem. But in the last weeks (probably due to the high summer temperatures) when the phone is very hot (because under the sun or when is highly stressed by protracted usage) the virtual button stops working at all. No vibration, no response. It works just as on-screen button, but only when the screen is on. Moreover, sometimes when I press the power button in order to check the notifications on the lock screen, the home button vibrates as if someone had pressed it, and the phone goes from the lock screen to the unlock screen, where it asks me to unlock with iris, fingerprints or pin.

    So I went to the authorized Samsung service center in my city (Italy, so explained my bad english) and with the technician we've tried a reset, a new flash of the last version of the firmware and the recalibration of the home button.
    Without success. The problem is still there.

    So he forwarded the issue directly to Samsung, that answered that for the 24 of july is scheduled a new update for the software they use to calibrate the sensor of the home button. This maybe means the Samsuns is aware of the problem and maybe the software that they use will be the solution. Or at least I hope so.

    So at the end of july I'll let you know if something really changed or not.
