Bluetooth no longer working on A40, latest OneUI - Samsung Galaxy A40 Questions & Answers

So I recently updated my A40 to OneUI 2.0 (Android 10)from Android 9 (after a factory reset which made me downgrade to 9 first in order to use my custom font with Hex installer (the Ubuntu Font). I paired my phone with my galaxy buds on Android 9 and used the latest Bluetooth Library Patcher Magisj module to keep the pairing. On updating to the latest OneUI and re-rooting my device, I found that Bluetooth straight-up doesn't turn on anymore. I click the icon in settings and it turns grey as if it was turning on but it doesn't turn on. I'm using the latest Magisk 22.0.

WiFi Bluetooth not working after Xposed Update

Hi guys,
I've been stuck with this problem for a month. PLEASE HELP otherwise I have to get rid of the phone...:crying:
I was on IMPERIUM 10 with XPOSED Framework active. One day it asked for an update of one of the standard module (I cant remember which one). After the process completed, I wasnt able anymore to use Wifi and BT. Even after reverting the module to the previous version or disabling XPOSED. Sometimes I could use WiFi and BT after a reset for a while, but again they turned off.
I've tried to reinstall IMPERIUM with full wipe, other SAMSUNG ROMs with XPOSED and CM11 (w/o XPOSED) but nothing. Besides, I've tried several modems (with ODIN) and NO SUCCESS as well.
Do you have any suggestion PLEASE?

Downgrade from 5.2 to 3.2 partly successful

Today I attempted to downgrade to Marshmallow. First I tried downgrading to 3.3, but that resulted in bootloop. I then tried 3.2 and it worked out all right. I left out the bootloader and flashed all other files included in the factory image. To prevent the forced auto update I used TWRP to move TegraOTA.apk to a folder of my choice (I have also blocked OTAs through my router since one cannot be too careful).
Most things seems to be working. I got a green light when I tried to pair Shield Accessories but managed to connect my remote by the general bluetooth pairing. I also had some trouble getting the Shield to discover my 5G network, but I solved it by changing wifi channel.
Edit: I get a green screen when streaming via Kodi (which isn't a problem if you disable hardware acceleration in Kodi's settings). Also can't get Chrome to detect the Shield when trying to cast. The two only major problem to rectify.

Android Auto issue

Hi everyone,
I'm new in this forum (I hope to post in the right section :angel: )...and I’m not a real expert on Android and smartphones … I have a Lenovo K6 (K33a48) with Android 7.0 stock as OS...I have some issues with Android Auto app (My new car does not recognize the phone). I’ve already check the USB cable (it works with other smartphone like Moto G4 and LG G3), the car system is supported (new Ibiza 2017) and I’ve already done the factory reset twice (but nothing change). So my question is: do someone know if android auto works on this smartphone with other OS ROM (like LineageOS, AOSP ecc)??:fingers-crossed:
Thanks in advance for helping!

Hi
I had a same problem with my father's K6 Note running Nougat Stock 7.0 (Rooted and Xposedv89)
Android Auto was working perfectly with the above configuration for months on Sony XAV-AX100 car AV system, and then suddenly one day it stopped working. No fresh install or any update specifically on that day.
I tried the following
1. Changed cable. Didn't work
2. Erased saved cars in the app and ensured auto add new cars was selected. Didn't work
3. Uninstalled and reinstalled Android Auto. Still didn't work. Had Updated all google apps initially itself.
4. Wiped Dalvik and Cache. removed SupperSU and XPosed. Still didn't work
5. Reset the phone and wiped all data.
6. Fresh Installed the Stock 7.0 ROM with any root and any other app. Updated All Google APPS. No luck. It still didn't work.
4. Tried the Phone in another car with a different AV System (Pioneer AVIC-F80BT), with same cable and also with a different cable. It worked with both cables.
4. Tried another phone (OnePlus 2 with Stock Marshmallow Oxygen OS) in the same Sony XAV-AX100 in my car. It worked. With all cables and usb type c adapters.
Strangely Lenovo k6 Note had stopped working only with Sony XAV-AX100...... I still haven't been able to find whats wrong.
got tired and am now using an old Redmi Note 4G phone (Nougat ressurection remix with Pico Google apps) with andorid auto on the Sony XAV-AX100. It is working.
beginning to hate Lenovo.......
i hope someone is able to find what went wrong.......just for poetic justice

Please answer this.

Seriously Needing Help
Phone Info - Mi A1
Rom - Resurrection Remix v6.XX OS-8.1.0 November Patch
Magisk v18 stable (used successfully 2 days after updating Magisk from v16 stable with no problem anywhere).
Modules - v4a, aml, dolby, selinux changer, busybox, MiA1 stock cam.
While updating "AML", screen got freezed for more than 5 min so i had to shutdown forcefully. But after restart i lost all installed apps and everything., from everything i mean both internal and external got formated. But that's not only the case. My device Mi A1 keep restarting automatically after few min of starting (it's not bootloop as device restarts to homescreen but freezes and restarts after few sec.). Sorry that i can't provide logcat as everything already formated.
i tried to reflashing using few unofficial and official MI tool (tried both oreo stock and pie latest) but still my device goes to setup screen and after few seconds it restarts automatically.
Isn't there any work around 'coz neither magisk support forum helped nor AML forum.
My only question is whether is this software issue or hardware? Can updating simple module result in hardware failure?
Please reply.

Settings getting rested after reboot

Hey, I'm using a SM-975f rooted with Magisk on a stock OneUI 4.1 ROM. I just noticed that some settings like paired Bluetooth devices, do not disturb or notifications settings are getting rested after rebooting my phone. I found a Magisk module about paired Bluetooth devices and it works well. But I didn't find anything about my other issues. Doesn't someone know how to fix it ? Or already had the same issues ?
Thank you ^^
