Folks whose devices fit the criteria of what I have (see attached screenshot of my "About Phone" screen), please read on. I say this only so I can figure out what is common between us to be having the following Bluetooth issue:
1) Bluetooth toggle switch is OFF.
2) You slide the switch to "on". The phone sits there for approximately 10-15 seconds, but Bluetooth doesn't come on at any point, eventually the toggle switch in settings slides back to OFF.
3) There is no setting/method in the device that will turn Bluetooth on.
From when I received the phone from Google Play store, the only thing I have done to it is root it following this method.
Clearly, something with the rooting process did this (I am also having one other issue, but that one is less annoying than this Bluetooth one). But everything in my phone points to me still having the stock ROM but just having root access.
If I can just see the common thread between my phone and others having the same issue, maybe I can figure it out.
I don't want to flash my ROM or start from scratch for the fear of making matters worst for myself; the device appears to be working fine otherwise.
If I am completely unable to fix this, my only hope is that the eventual release of 4.4 KitKat would fix it on its own (and probably break my root at that point, haha).
After searching high and low for an answer to this, I ended up doing a factory reset (Menu-->Settings-->Backup & Reset-->Factory Data Reset) and that resolved the issue (while wiping my phone).
Thanks to the Android OS, I let my phone charge overnight while on WiFi and by the morning all the apps were reinstalled and updated, including the OS itself. My Kernal/Baseband/Build versions are all back to the ones I had when I got the phone from the Google Store, so that's comforting.
Now, I just have to find the absolute least intrusive way to root my phone without any ROMs or system-level updates that could screw up stuff like Bluetooth or USB Connectivity for me.
I have a stock unrooted Verizon Galaxy S5. For several months my phone has been plagued by several issues at startup. Whether I reboot the phone or start it up after the battery has died, it always enters an odd state immediately after loading and seems to get stuck in this state for an undetermined and variable amount of time (anywhere from a few seconds or minutes to hours or even overnight).
While in this state, this is what happens:
1. Screen stays on. Once I unlock the phone, the screen stays on. The side button doesn't do anything to lock the phone or turn off the screen. Holding down the button, however, still triggers the power menu. The screen timeout never triggers, even though it should turn off the screen after 2 minutes of inactivity.
2. WiFi and Bluetooth turned off. Even if they were turned on before I powered down the phone, they are not enabled when the phone first boots up. I can manually turn them on but the WiFi will not connect to a network, even if one is available. It may show it is connecting to the network, but it gets stuck at "Checking the quality of your internet connection" and continues to use the 4G network for data connectivity. This happens no matter what WiFi network I am within range of, so it's not an issue with the network or router itself. If I am not near a network at all I will still experience the other problems of not being able to lock the phone, etc.
3. Startup applications don't load. I have Tasker on my phone, but it doesn't load and show it's notification bar icon.
Otherwise, I can use the phone normally and open applications, surf the web, etc. It seems that loading some applications and using the phone eventually causes the phone to exit this mode, but I haven't been able to find a single particular application or series of steps to fix the problem. If I power on the phone and don't use it that just seems to make it take even longer to fix itself.
Once it gets out of it's weird state, the WiFi connection will become active (it will turn on WiFi if I haven't done so manually already) and it will connect to a known network if one is available, the phone will lock itself or I can do so from the side button, and things like Tasker and Power Save mode will turn on.
I am stumped as to what could be causing this problem or how to fix it. It seems the phone may be doing some kind of check, maybe related to Knox, that hangs during startup and prevents certain things from working until it straightens itself out.
Any clues into what this problem is, what is causing it or how I could further analyze this problem and determine its cause would be greatly appreciated.
Never heard of or experienced these issues. May want to contact Samsung.
Have you installed any official updates from Verizon at any point? I've heard of phones having phantom problems like this after receiving a bad update. I would definitely contact Verizon if you did update at any point. If not then like BigBot96 said, contact Samsung about the problem.
My wife's Note 2 did something similar when the battery died. I had to factory reset. Her phone was rooted/unlocked & running a custom TW ROM, though. May I suggest doing a complete factory reset and Odin. Backup data to computer or external sdcard since this will clear the entire device.
Edit: After rereading OP's post it actually sounds like an app is hanging at startup which could cause this behavior. A logcat should tell you what's going on.

Hello All,
So a few days ago I received an update with Baseband Version N910CXXU1DPI1
After the update completed and the device restarted, I noticed the wifi keeps going on and off on and off if it's not connected to a wifi network. I went to the wifi settings to make sure if any other wifi settings in the advanced menu are ticked and found that nothing is ticked which is good.
The problem disappears only if I restart the phone. Is this a common problem with this update or is it just me?
Thanks
Hi me too, I have similar problem after update to N910UZZH2DPJ2.
When I turn off wifi, the wifi icon in the notification toggle switch on and off automatically, i.e. turn green and grey automatically.
When I go into wifi settings, the switch also turn on and off automatcally non-stop.
They will stop when I connected to wifi.
I have already do a factory reset, it doesn't fix the problem. Any idea how to solve it? Thanks!

I think someone needs to report this to Samsung....I would do so but I'm not sure how. Let's just hope for a small patch that will fix this issue..it's very annoying
Yeah me too, Wiped the cache and still nothing. Wifi keeps randomly restarting off and on until i restart. But the problem comes back after restart................... Can someone Please help us all....
Thanks for the feedback guys. Glad I'm not the only one with this problem. I think I might just flash with Odin to the previous version, or if someone can help us that would be greatly appreciated.
Is there a way we can report this bug to Samsung?
I'm having this issue also. Is this why I'm seeing lots of posts about folk downgrading to 5.1.1; issues with the 6.0.1 roms/basebands? Before I updated my firmware I had the issue reported by another user on here where my WiFi kept turning off immediately after I tried turning it on.

I never had an issue with Marshmallow except for this random wifi on off issue in the latest update. Been on stock rom since I got my phone back in December 2014 !!!
Hey everyone I was able to temporarily fix this issue by turning off wifi scanning in (Settings > Location > Improve Accuracy). I heard somewhere on here it might have been a recent app update that is causing the issue.

Thanks for the tip 93_teg. Going to give this a try and report back.
@93_teg I did your solution and so far it seems to be working. No more Random wifi on off issue, let's hope.
Thanks for the help
@93_teg thank you so much for sorting this out it switches off now without restarting :good::good:
Thank you for the fix, I spent waaaaay too long troubleshooting this issue. I think the next step on my list was sacrificing a lamb but this works too
today's update(N910F PHN) didn't fix it.
it's probably the latest Google play services update that caused it, it received an update shortly after the October security update.

I received an update on my phone yesterday but have Postponed it...going to see whether it fixes the issue or not.
Thanks to all who participated in the thread...greatly appreciated
Workaround
Hello,
I confirm that the issue is due by the Service Google play. The workaround, to stop the Wifi is blinking, is :
Parameters > Applications Manager > choose system applications (Three dots) > select Service Google Play > Stop forced (and possible Stockage and clear cache).
This workaround works after each use of the WiFi.
And now wait a solution from Google (and Samsung may be).
Thanks
Hi, its my first time writing here, but not using this forum.
First of all, sorry if my english is not good enough.
I have a Nexus 6P stock, without root or anything. This week I installed Android 7.1.2 from google beta program, after that, I was having draining battery issue, so, I checked the battery usage and discover that the Wi-Fi never stop, then, after reading on some blogs about this problem and found that I should go to WiFi setting and disable some option in "keep wifi on sleep", however, when i click on setting key, always appear this messages "Settings has stopped" and "Settings keeps stopping". Things I did:
1) Disable Wi-Fi, try clicking on setting key - still the problem
2) Restart on safe mode - still the problem
3) clean the cache from recovery mode - still the problem
Any other suggestions without restoring the cell phone?
Thanks in advance

Hi... The gear icon force close... It's a bug in this beta version, nothing you should worry about.
However, I have no idea for your battery drain...

Have You tried with - Settings - Location - press the 3 dots - Scanning - And disableing everything there ?
So...if I can't access the wifi settings is there any way to disable the wifi optimization or otherwise prevent it from dropping a wifi connection that it detects has no internet?

Unfortunately the only thing that usually fixes that is a factory reset. And if that doesn't work it's a ROM issue. Even though it's a stock ROM it happens.
Your best bet is probably a factory reset at this point. Usually if Settings or another system app is crashing on Stock, something is pretty messed up. You could either opt out of the beta and it will wipe/downgrade for you, or you can download a factory image from Google and install it manually if you're so inclined.
I have the same issue on my s6 after it updated to Nougat. Settings crashes every time if I try to open wifi, no matter what. Already wiped system cache and started in safe mode, but the problem is still there. Has anybody figured out a solution to this?
Did you try what was suggested..... ?

I tried everything except factory reset, which I don't want to do yet.
I have this problem but I'm running Nougat on a stock "International" Samsung Galaxy S7.
I've tried factory resetting which fixed the issue for a while, but now it's come back.
Possible Fix Found!

I may have found a possible fix for this issue. Head over to this Android Central Thread where I've been discussing the issue with some other people.
Good luck!
Before updating I had the dolby app disabled. After the update it was still disabled but the service seemed to be running because it was affecting the audio quality, so I re-enabled it, turned off the dolby processing, and when I was about to disable the app back I got my first reboot. After it went on again I was able to disable it. Started playing some music to check if it was disabled and got another reboot. Now every once in a while happens. Has anyone else had the same problem?

Maybe try to force stop Dolby app then erase data and try again.
For now seems you're the only with this problem

Made a factory reset, didn't disable anything and I have got at least two random reboots. How can I get a logcat of what happened before the reboot?
[EDIT] Found that the random reboots only happens when I'm at the office, connected to a hidden unmetered WPA2-protected Wi-Fi network.

You run Catlog app (for example) and wait for the reboot. If it's plain that it only happens with that Wi-Fi connection, then just run Catlog, connect to WiFi, boom. Check logs afterwards
Has anyone found a solution?
I'm having the same issue. Has anyone found a solution? I already factory reset the phone, but the random reboots persists, and it's only when connected to my home router, it never occurs when wifi is off, and hardly when connected to other APs, wich is very strange.
My device is RETBR, I'm not rooted and never unlocked my bootloader.
Thought about reflash the rom, but i don't see how it would help.
Workaround
Hi, just updating this thread because I maybe have found a workaround. After I installed Blokada, witch uses a VPN, the phone stoped rebooting when connected to my home WiFi. Probably the VPN changes the way Android connects to the internet thus solving the problem. Blokada isn't a real VPN service, it only uses the API to creat a way to block adds, so other apps that uses VPN like that (1.1.1.1, intra, etc) should work as well.
This is a really weird bug, that onky happens in some specific conditions. I didn't found to much people reporting this, but if someone is having the same issue, I hope this "solution" could help.
Have you tried reflash to Oreo Stock?
Maybe after flash Oreo Stock your cellphone working fine.
