Android 9 pie - slow wifi

[wenna.speedy]

Hi, I am facing one huge problem (except some little ones). When I turn on bluetooth, wifi speed rapidly decrease. When I turn BT off, everything is ok. It seems it is bug on pie, because I wasnt this problem on 8.1. Some time ago, on my redmi 4x, I had the same problem, but some update solve this. Can anyone confirm my assumption?

It's a known bug since Pie, let's hope Xiaomi will fix it before we get Android Q.

Actually I got this bug with the OTA 9.6.11.0 Oreo update where there was a corrupted modem.img included and since then I had many network/SIM cards problems. I did many things to get rid of it (just see my other posts) and finally I got my phone to work with Pie by updating to 10.0.2.0 via MiFlash, then via OTA to 10.0.3.0
