Galaxy A40 [SM-A405FN] Bluetooth pairing lost if rooted ? here is the solution - Samsung Galaxy A40 Guides, News, & Discussion

I was wondering why on my A40 rooted each time i had to re-paire every bluetooth device and so, the smart lock wasn't working...
I found a magisk module that solved my issue : Magisk libsecure storage companion module description
just go to magisk manager,then the three dots on top left, then downloads
after that on top right just search "libsecure"
install it,reboot.
that's it
Hope this can help someone.
Fred.

Problems, bluethooth and RSAP.

I tried it, Bluetooth saving paired devices works, but sadly it breaks my WiFi when using it.
I'm using the J firmware.

[Q] Bluetooth Issue

Hi guys, i am currently using Rocket Rom v23 and abyss kernel. At first my bluetooth device (wp 250 creative headset) is working just fine. But after several days the bluetooth is not working anymore even though it can recognize the device but when i connect it there is no music playing.
i tested my bluetooth device and it works on my sgs and itouch
i tested my galaxy note bluetooth to pair with sgs and it works
-what i did to resolve it before was to go back stock rom then v22 to v23 but it is hell of a work.

I remember I had this problem with Sennheisser MM100 headphones a while back. From memory I unpaired and removed the device, then re-paired the phones. I may have done a reboot of the note after I unpaired the device, can't remember as it was a long time ago. I have not had a problem since.
I have the same problem as kwelito_88. I managed to use my Creative WP-250 headset for just 3 weeks before it decided to stay mumb on me.
I "unpair" the headset with my phone but now my phone just couldn't see this headset when it scans for devices.
Any one out there know how to get both gadgets working again? Thanks.
Do you have a BT laptop you can try pairing your Note with? If it works that will rule out the Note as the problem.
You've probably already fully charged the headset and checked that they are definitely in pairing mode so that the Note can see them? My Sennheisers are bit touchy and didn't go into pairing mode properly until I pressed harder on the switch button.

Thanks! I can now confirm the Note is not the problem.. it pair & connect to my BT laptop easily.. So the Creative wp-250 headset is where the fault is. Guess I won't be looking at Creative products for a while.
Thanks for the tip
Hmm. I have a duff/non-compliant Jabra headset too. That tip with pairing with "known good" worked a treat.

Bluetooth Near not working properly?

Wanna start apps when I'm in my car. When BT is enabled my Profiles work and detect the near devices. If BT is off it seemes Tasker is not scanning for BT at all.
Bug or Feature?
Using latest Tasker on Galaxy S7 edge.

Same here. I'm using RR ROM.
Have you found a solution?
I know this is a year old but I found a bunch of posts like this while looking for the useage of BTNear, so I figured I'd throw it out there for the next guy. It sounds like you didn't select the "Toggle" option. Without it, it will only turn on your Bluetooth the first time and it leaves it on to scan every X amount of seconds. It won't Toggle on, scan for BT device and then toggle off. Would explain why it runs fine at first and then after you turn off Bluetooth when you reach your destination. It either tries to scan with BT off and fails or it breaks the code when BT is mysteriously off and exits. Hope it helps someone.

Bluetooth issue

Dear all
First post so here goes. Had my 7 plus exactly a week.
Specs as follows:
Model TA 1055
Android 8.1
1st June 2018 Security patch
unrooted but themed with Substratum (Swift Black)
So my phone won't detect either my amazon bluetooth adapter plugged into my bedside radio or my creative bluetooth speakers. My lenovo p2 can find these without issue. Strangely it can connect to my PC's bluetooth which gives a passcode. I've cleared bluetooth cache and still not fixed. Anybody else had bluetooth issues?
TA-1046 here with June patch and I have bluetooth issues as well.
I was not able to connect my Gear S3 smartwatch to my phone, untill I decided to turn off BT and turn it back on again.
Suddenly it worked.
Then I was not able to update my S3 apps from the Samsung App Store, untill I stopped BT and turned it back on again.
It seems to me that there is a BT issues in the June patch.
How it was before, I don't know as I received this phone 2 days ago and it updated automatically to June update.
Sorry for adding more negativity to this forum than assistance.
I am also having similar problem with connecting to my LG sound bar. It picks it up when i search, saves it but does not connect.
BT issues
Well unfortunately I have to say same. BT even can't see any device during scanning. Other devices each between other works. Other devices also see N7+ and can pair with it. Seems like scanning doesn't work for me on N7+.
I tried reset networks, clear BT cache couple of times - didn't changed anything. Still wanna avoid factory reset.
No mods, no root.
I'm bit surprised (in the sad way) by this device :-/
In the meantime BT has worked quite well for a couple of days, untill today.....
I could connect to my Gear S3, but not much later I notice new notifications on my phone but no popup on my watch.
It turned out that BT was not connected anymore.
Manually connected and the same process happens again.
Untill I rebooted my phone. From then on, my watch stayed paired with the phone and didn't loose connection.

Try resetting your Gear S3 to factory defaults and remove BT settings on phone.
(also clear BT cache).
I had to set up my watch a couple of times.
Still it disconnects sometimes, but then a normal reboot of the phone helps to get the connection back.
Submitted this to another thread, but I'll copy paste it here.
I recently got Bluetooth headphones and found that playback easily got choppy if a part of my body was in between my headset and phone, or if the phone got locked. I did find a solution to this however, and not sure if it would work for everyone that has Bluetooth issues as well.
It seems as if Bluetooth has its own app on Android 8.1, and due to this, it's getting managed by Doze or the automatic app power saving that's on by default. I switched off battery management using the following steps:
1. Go to Settings
2. Apps & Notifications
3. Tap on the option that says "See all x apps"
4. Tap on the top right hand 3 dots.
5. Tap on "Show system"
6. Scroll down until you find "Bluetooth" and tap on it
7. Tap on Battery
8. Tap on Battery Optimisation
9. Press the blue dropdown that should say "Not optimised", and select "All apps"
10. Find Bluetooth again, tap on it.
11. Optimise should be ticked, tick "Don't Optimise" instead, then press Done.
My Nokia 7 plus cannot find other Bluetooth devices.
I cleared cache, went to battery optimisation settings, ticked on the Bluetooth icon and selected *"Don't optimise"* turned on my Bluetooth to search for other devices and still this same problem persists. Can't find other Bluetooth devices including phones, tablets and headsets. I'm really confused on why there should be such a problem. I don't want to Reset to Factory settings. But I'm not being left with any other choice. I'm so upset that I have to spend so much and yet other cheap phones can search for other devices so easily.. please I need a solution immediately

Samsung Galaxy Watch will not pair/finish setup after installing Magisk

Hello,
I am curious to see if anyone else had or still has this issue and if there is a fix for it.
Devices involved:
Phone - Samsung Galaxy Note 9 (SM-N9600) Android Version: 8.1.0 Build Number N9600ZHU1ARH2 (08/01/2018 release)
Watch - Samsung Galaxy Watch 46mm (LTE model through T-Mobile) on latest firmware
Before rooting with Magisk I was able to pair the watch to the phone using the Galaxy Wearable App and use the watch with no problems.
After rooting with Magisk v17.1 (stable) I was no longer able to pair the watch. It would start out fine by showing a matching passkey on both devices. I accept the code and they would begin to pair. Once the watch displays "Use phone to complete setup" is when the problems presented.
The Galaxy Wearable app will say its pairing the devices but shows nothing and keeps sending a notification saying it sees the watch and asks to connect or cancel. I tap connect and I get a white screen with a spinning circle. After 3-5 seconds the white screen goes away and 3-5 seconds later I am asked to connect the watch again.
If I go to Settings>Connections>Bluetooth (on the phone) I can see the watch is paired but the app will not complete setup. (I can pair to my car Bluetooth and JBL Charge 4 speaker with no problems)
I am using Magisk Hide on the Galaxy Watch Plugin, Galaxy Wearable App, and Samsung Accessory Service but that hasn't helped. Nor does uninstalling and reinstalling Galaxy Wearable App.
I upgraded Magisk to v17.3 (beta) and still have the same issue.
SafetyNet check pass on ctsProfile and basicIntegrity
Any thoughts?
Also, does anyone know how to get rid of this annoying notification from SecurityLogAgent that says:
"Security Notice
Unauthorized actions have been detected. Restart your device to undo these actions"
Tapping on the notification opens Device Security and then tapping restart in device Security boots to TWRP
Thanks!!

Try checking rarely used devices on Bluetooth menu. Sometimes non original earphones do not share device name.
