S8 Software bugs - Samsung Galaxy S8 Questions and Answers

Hi,
I recently purchased a second hand unlocked S8. It seemed to be working fine for the first 30 mins. When I did factory reset. The home launcher keeps crashing along with the bixby button.
Also I tried connecting to Smart Switch and it didn't seem to detect the phone although adb did. Tempraroy solution could be to switch the launcher to google one and maybe change the function of the Bixby button.
What can I do to restore the phone to Samsung original firmware? I want to be able to get future updates from Samsung. I appreciate all your help.

Phone stuck in Samsung logo screen

Hey all,
I have this problem with my Samsung Galaxy Spica (Android 2.1) since a week ago.
The problem started when it took a long time for me to get into the homescreen of the phone on startup, and I was having problems viewing contact list or the messaging application or when I go settings->application-> managing application. The phone keep booting me back to homescreen when I tried to access those pages.
When I reboot the phone, it took really a long time(around 15mins), and some luck because I had to try a few times to get into the homescreen. The problem still exists with the contact list/messaging app/managing application page. Other apps seem to work fine.
Then, I tried to switch to another homescreen, was on LauncherPro and I tried to switch to Pantheon. It seem to be broken and the screen goes blank and on, and Pantheon couldn't load. I press the home button, and I managed to get back to LauncherPro. So, thinking that the homescreen may be the problem, I made Pantheon the default homescreen again.
But to my despair, when I restart the phone, it still won't get past the Samsung logo and this time the problem seemed worse. After trying for hours yesterday, I managed to boot it past the Samsung screen, and I hard reset the phone by keying *2767*3855# in dialpad, in hope that a reset will get my phone working again. However, it still didn't work..... And I'm still left with a phone that is stucked on the Samsung logo.
Anyone have any solution to it? Anyway I can reset/flash everything in the phone, because maybe there is some corrupted files?

[Q] menu smart key stops working

I got my A7 and flashed the 4/17 rom right away, used it stock for a couple of days then installed dexters mod1.42 and for a day or two it worked fine. Then the menu key stopped working. sometimes it would work for an hour and then stop working again. I deleted the dexter mod, wiped cache and did factory reset when the key worked and everything was fine.
Then I did the bestialbub a7-gapps zipmod and everything worked great for 4-5 days then the same problem, no menu key. are there any known apps that may cause this problem? I am waiting for the menu key to work again so I can try again, are there any settings or other mods that will get me the market but leave me close to stock.
steamtv support just had me do a reset and flash latest firmware and that doesnt help much.
Please, I love the A7 when it's working and need some help.
Thanks,
Billy
Does this happen when the back of the device is hotter than warmer? I've had this happen often when the days are warmer and hotter. That's the reason why because the heat affects parts of the wiring. The other solution is to use Button Savior (an app on the market).

The menu smart key comes and goes no matter the temp. It's not working now, sometimes it will work for a little while and then stop again. I can't wipe/reset without the memu key. I want to get it back to stock to see if it's a hardware problem then take it from there. Any suggestions anyone?
billy
same here (I thought, I'm the only one encounter this kind of problem). My Aunt gave me A7 as present. after 2 days, all the smart keys malfunctioned. it works fine for 10 min after that it wont work anymore. I've installed button savior for remedy. I think ytain is right, A7 has problem when the back of the device becomes hot.
Hello,
I had the same issues with some of the keys of the keyboard. but at first it started only happening when the battery was low but recently it was happening all the time.
This was making my life difficult as i write some sms to my friends and it's quite annoying.
I left my phone untouched and went to repair center of my provider to show what was happening. Put my phone there for repair and in the same day went there to pick up the phone good as new.
The issue is that the stripes connecting from the keyboard to the cellphone were a bit fragile and probably broke or it wasn't making any contact whatsoever. Now i have the phone working 100%. no problem.
Hope this helps

Home button unresponsive, lock screen comes on by itself.

Update: So today at work it decided to behave seemingly out of the blue.
Heya,
So I have a problem with my Note 4 that I just cannot figure out this time around. I found that the lock screen was turning itself on even when left alone on a table and on top of that the home button is not working. After I installed a security update I had put off installing the home button worked again for about 10 minutes or so. I figured it was a software problem so opted to factory reset the device. No problem getting into the recovery menu by holding power and volume up.
Once that was done though the problem persisted. I'm inclined to think it's hardware but I figured before I throw down money on parts I'd get a second opinion just in case I'm missing something.
It's a N910-P running 6.0.1 and April's security update. Any ideas/suggestions would be appreciated.
Thanks!
My device is doing exactly the same thing all of a sudden... Seeing a few other threads with similar issues... I'm guessing a Google Play Services update, as the play store icon changed just about when it happened...

Not able to see the minimized apps

Hello all, it's been 5 days since I owned Max Pro M2.
And all of sudden I am getting this weird issue where I am not able to see the minimized apps when pressing the overview button. It always shows No Recent items and it's really quite annoying when trying to move between apps.
I have tried the following options to resolve it but nothing worked so far.
1. Restarting the phone
2. Phone Off and turning On back.
3. Uninstalling the greenify app.
4. Resetting the app settings
Any suggestions or solution will be really helpful.

That's the same problem I am facing after FOTA update for the month of November
Solve for the issue- No Recent Apps
Thanks for the question. I bought Max Pro M2 and recently got stuck at no recent apps screen.
So as remedy I tried out something and it worked.
1) Press the power button.
2) Hold on Power Off option for few seconds. Just keep holding onto the option.
3) The device will boot and take you to the safe boot mode.
4) Now check if you have any recent apps on or not.
There will be apps unless you have deleted all.
5)Now reboot your device.
6) Check recent apps and you will get minimized apps there.
7) If nothing works, then try checking any there is any issues with screen pinning. But I am sure doing upto step 6 will be able to bring back your recent apps.
Thank you.
Thanks for the response. I am facing this issue very rarely and I will try the above solution when it happens again.

[FIX] If your home button stopped working

Last week, I took my phone off the charger and noticed that the home button was not working. Did multiple reboots, clean wipes and also reinstalled the stock ROM, nothing worked. Did the *#808# fingerprint test and found that the figerprint sensor was not responding which led me to believe this could be a hardware issue. I did not have the time to go to the service center so I turned on the on-screen navigation bar and used it like this for a few days.
Today, I thought I'd try to sort this out one more time before I take it to the service center. The *#808# fingerprint test still showed the sensor not available. Rebooted the phone and turned the on-screen nav bar off. Lo and behold the home key started working. I do not know how this happened, I'm just glad that it did.
Just thought I'll post here so that if anyone has issues they could try this out and it might help someone.
Cheers.:good:
I got the same problem. My OP5 Home button(with fingerprint scanner) stopped working suddenly. It got stock android since purchase. I never tried to root it. It suddenly became unresponsive. Will try to use nav bar for few days. Im getting ghost touches as well. Any Help appreciated.
Hi. I have the same issue on my op3t, looking for idfeas.

Hi. I have the same issue on my op3t, Oxygeos Version 9.05. My home and recents buttons do not work but fingerprint works fine. I turned on the on-screen nav bar and the home and recents buttons don't work there as well. Turning it off didn't solve anything. Any idea? Thanks
Facing exactly the same issue after upgrade to 9.0.5. home and recent buttons are not working, but fingerprint is working fine. Did you resolve this issue by any chance? if yes, please let me know as well how it was resolved. thanks. -ramesh
Try doing a factory reset, but take a backup before doing that.
Sent from my OnePlus 3T using XDA Labs
I am also facing this issue. It started off with a boot loop into the recovery every time i try to start the phone. It stopped after i cleared cache from recovery, but the default launcher doesnt work properly, no notifications in my drawer, and many other issues. the hardware buttons are responding (it lights up when i tap on it) but the OS doesn't do anything with it. I have tried with switching to the soft keys and it behaves the same way as well. the fingerprint scanner and back button works so far.
i'm having this problem too Got a OP3T, i found out a bit of info, it has to do with the screen, i'm still facing this problem so im gonna buy a replacement screen and see how it goes, ive already replaced the earphone jack board that houses most the flex cable connections and i also replaced the speaker, home button, and the usb c flex cable to no avail. what i haven't tried was to replace the battery and the main/sub flex cable inside. i'd really like a fix for this.
go to Settings -> Apps -> All Apps (ie including System apps)
look for com.android.fingerprint... or com.oneplus.fingerprint...
"Force Stop" it. and go to its storage and "Clear Cache" , "Delete Data" .
Now restart the Phone.
Worked for me on OnePlus3T running OxygenOS 9.0.5.
Phone was also on charging through out the procedure .. I doubt if it would have any significance though.
Good Luck.
I could not force stop this app.
MY SOLUTION
this is what it worked for me with OP5
I deactivated fingerprint, reboot to recovery, wipe cache+dalvik, restart (without fingerprint anymore) and it seems to be working just fine again.
I have observed this issue too in my oneplus 3 with oxygen os 9.0.6 and also in previous releases. The only thing that works for me is just to reboot the phone.
