Hi,at first, sorry for my english, now to my problem:

When i was upgrade my phone to Android 9 , there was a problem with Wifi speed. When i turn ON Bluetooth, Wifi speed is about 90% lower. When i turn OFF, it is good again.
I read this problem was solved about year ago, but i still have this problem.
When i bought this phone, there was Android 8 and I have no problem with this.

Thanks a lot for your advices.
