Oppo f1 plus Bluetooth issues

I purchased oppo f1 plus yesterday.
I am having problems connecting to any bluetooth device. First of all, the mobile keeps on searching for a bluetooth device for ever and when it gets connected the music breaks while playing.
I have also noticed that mac address of wifi is identical to mac address of bluetooth. In every mobile phone mac address of wifi is different from mac address of bluetooth.
Went to the service center they replaced the phone with a new one, the new phone is having the same issues, then we tried with three brand new oppo f1 plus models with different 4.0 bluetooth devices but the same issue is there.
Service center people updated the software, factory reset the phone, but the issue is still there in oppo f1 plus models.
We notice one thing if we remove the 4g sim from the phone then the bluetooth starts working fine. but then whats the point in buying a volte enabled phone.
Anyone else is having the same issue. Kindly post and share how to fix the problem.
I'm having the exact same issue on the Oppo r9 plus. Did you find a solution?

wifi authentication issue on lenovo yoga tab 3

Hi All,
I have a lenovo yoga tab 3 8 inch tablet. Since last week I am facing issue with wireless connection. Due to unknown reason, my wifi setting shows wifi authentication failure or saved. I have around 6 other devices that are connected to my wifi router, so I know the router is working fine. I have reset the tablet also, but still the same issue. It works for few minutes and then shows the same error.
I also did reset the router, though restored it with my configuration backup. Now I am lost with alternatives to fix this issue.
Android version I see in general info is 5.1.1.
Has anyone come across this issue before. What options do I have to resolve this?
Thanks

Wifi problems with oneplus 6?

Hi,
at the Moment i have the oneplus 3 but i have some wifi problems. Sometimes the wifi disconnect when the screen is off or it isn't auto connect when i'm at home. I have found other threads from users reporting the same problems. Some reported this is because of the poor wifi chipset build in the op3.
Has the oneplus 6 the same problems? I want to use it with LineageOS.

Might not be related, but I had a weird issue with an Asus router. My OnePlus 6 would force the router to reboot once in a while when connecting . You can find people asking questions on reddit as well. The solution was to go to LAN -> Switch Control and set Nat Acceleration to Disable. Not sure if it is a OnePlus 6 problem or Asus router problem.
Other than that - smooth sailing, had no issues.
I can't search 5g wifi band

Hotspot issue on android 11

Hello, I have been having a weird hotspot issue on my S20+ 5G. I do not think this is device specific as it has happened on my S10 5G. It seems to be android 11 related (don't recall it being an issue on android 10)
Little context - I play online games through my hotspot, and randomly it will stop working. Everything says its fine on the phone. However, it says 0 devices connected and I cannot connect unless I toggle off then back on the hotspot. At first I thought it was interference from local wifi networks - but mine is the only one at 149 channel (checked with WiFI Info View).
I only notice this happening when gaming. If I am streaming anything, it is fine. The phone has internet too, so its not the service.
My first thought is some sort of battery saving thing. Like, could there be something in android 11 that causes this cause there isn't enough data throughput?
Im just wondering if anyone has any thoughts to try. I have disabled all known to me battery saver things.
Extra info: Definitely seems related to wifi hotspot only not USB
