Bluetooth turns off when restart phone - OnePlus 3T Questions & Answers

It seems whenever i reboot my phone, bluetooth would be off when the phone turns back on.
Currently running stock OOS 4.0.3 rooted , I dont recall having this issue when I first got this device, it started happening recently.
Is it a bug with 4.0.3 or is it just me?

This happened to me a while back too. It started after I updated Nova Launcher though the Play Store for some reason. Dirty flashing OOS 4.0.3 fixed it.

I have the same issue. I'm unfortunately a noob and a fiddler and have had to restart my phone a few times in the last week. I only realise that the Bluetooth is off when i don't receive notifications on my watch.
I'm currently downloading OOS 4.1.0 and hope this solves​the issue.

I've been installing the upgrades to the stock OOS and today I installed the beta 4. My bluetooth still turns off after restarting. Any solutions?

I am currently on 4.1.0 , seems the issue is resolved for me

Open Beta 4 does the same thing.

I'm still facing this issue on latest OP3T OTA update

I had the problem coming back after updating to OOS 4.1.3
I cleared the cache and it seems to be fixed, tried rebooting several times and bluetooth remains on

Wifi/Bluetooth Won't Turn ON

I recently updated my HTC One M7 from Android KITKAT to lollipop via OTA.. Before the update my wifi/Bluetooth are both working fine, at the first few hours after the update, my phone seems to work just fine then suddenly my wifi/Bluetooth are not turning ON, phone restarts randomly and stuck to the HTC One logo page. I search the web and follow the idea of rebooting to safe mode, rebooting to recovery clear cache/partitions and hard reset my phone many times but none of these works. I decided to revert back to kitkat (RUU) but still no working wifi and Bluetooth. I even tried to run the jelly bean which I believe is the original version when I first bought the phone, to my frustration, I STILL DON'T HAVE A WORKING WIFI/BLUETOOTH. Any solution?

Bluetooth crashes OP3T on newest LineageOS builds

Hi,
with the newest builds of LineageOS for the OnePlus 3T im facing similar problems like in this post here ...
https://forum.xda-developers.com/oneplus-3t/help/lineage-os-bluetooth-crashing-op3t-t3561225
This applies both for the 20/03 and the 24/03 build. When I enter the settings and go to the Bluetooth section and there enable BT, the phone becomes unresponsive for some time and then reboots. What I found out is that if I enable BT via the status bar shortcut, everything is fine and my previously connected device (gear s2) reconnects stable. But if I then enter the settings and just click on the BT section entry, same story again, phone becomes unresponsive and then reboots. I flashed the ROM and then the OOS Firmware 4.1.0. Phone is rooted with SuperSU.
Have you tried a clean flash?
not yet. just dirty flashing with wipe cache and dalvik so far. i guess I'll give it a try then.

I don't know what did the trick now but this is what I was trying...
I cleaned the cache + data of the Bluetooth system app and reinstalled BusyBox, then rebooted. The problem seems to be gone, no more crashes and freezing OS. Will leave it like this for me now. Just wanted to let you know as I don't seem to be the only one with this issue.

All,
just wanted to give an update on this topic and hope for a solution
As the problem was coming back I decided to go for a full wipe and clean flash of the latest LineageOS version for the OnePlus 3T from this thread here: https://forum.xda-developers.com/oneplus-3t/development/rom-lineageos-14-1-t3547024
After I restored my apps I activated Bluetooth on the device and flawlessly connected my Smartwatch, a Gear S2. All good, all fine, all working.
AFTER that, when entering Settings => Bluetooth on the OP3T, there are 2 possible scenarios:
1) No other Bluetooth devices are around and emitting, the search stops after a few seconds saying that "no other BT devices are detected" ... makes sense.
2) There are other Bluetooth devices around and emitting, and based on my experience only one device is sufficient. The search goes on and on and on, after a while the screen freezes, and then the phone warm resets.
I was able to reproduce this inside my car when I tried to connect to the car audio system and also with my Bluetooth headset. Devices turned off => scenario 1, devices turned on and ready to connect => scenario 2.
Any idea here?

Bluetooth pairing disappears after reboot

I have a Verizon Note 9 that recently received the Pie update. Bluetooth has always been flawless while on Oreo with this device. Now after updating with the Verizon OTA Pie update, my bluetooth pairing disappears every time I reboot or shut down and restart. I have cleared the cache partition. I also cleared the bluetooth cache for good measure but this was unsuccessful. I have seen some rumblings about this on Android Central but I have not seen any solutions. Anyone else seeing this here? Has anyone found any workarounds to this bug? I have not factory reset my device yet.
Thanks in advance.

Over on reddit someone replied to a similar post with a recommendation to reset network connections. This wipes out all Bluetooth and Wi-Fi settings. I did this and it seems to have helped for now.
Edit: The auto restart was scheduled for the weekend and my bluetooth devices were wiped out again after the restart.
Hello I had the same issues with Bluetooth devices being removed from pairings. I did the network reset and manually restarted phone with no issues but with Auto Restart it was back with the same issues.
From what I think it is, the auto Restart might be the issue for this problem.

I have never used the auto-restart feature before. All my bluetooth devices are gone after EVERY reboot. So very frustrating. I have even factory reset the entire device and set up from scratch 2x now. Problem persisted
Tonight after the CSC2 update (March 1st security patch) it finally seems to be fixed! :good:

Sony XZ3 Android Setup crashes

Hi,
I have a big problem with my xz3. I flashed it multiple times via Newflasher but right after startup there is the fault Android Setup crashed. Wait or end. I wait and then it continues but WiFi is not found.
Before the problem occured there was a ota Android 10 setup. Also I dropped the phone accidentally. It worked a day or so and then the crashing startet.
Is there a way to wipe everything and get this phone to life again.
Thanks
( I don't know if this is the right forums. Sony forum is a bit empty)
I'm currently facing the exact same problem
The phone randomly crashes and reboots in addition to the wifi and signal drop issues you mentionned
I have searched everywhere but haven't found a solution to this
Has anyone found a solution to this ?
I tried to reflash it with xperia companion and multiple stock versions with flashtool, some checking wipe everything, still no wifi.

Did the issue fix itself?
I am encountering the same issue and looking to know if it is a phone thing or an update issue.
I factory reset the phone but the issue is still occurring.
I tried downgrading to 12.5.3 but it didn't work. Seems like roll back is prohibited at my phone.
The issue stopped occurring for approx 9 days and yesterday without doing anything it started reoccuring and has not stopped since.
The issue keeps reoccurring even in safe mode.
I am totally confused. I don't know what to do
The same issue with mine also after updating to 12.5.4. The phone can't be used while every 2-3 minutes disconnects from network. Any ideas?
