Strange thing is happening with me. I am using Xiaomi POCOF1. When I use normal internet, the speed runs at 2300 frequencies, in which speed is too slow!
Normal speed test :-

And when use internet during a call, the internet runs at 1800 frequencies, in which the speed increases.
On call speed test :-

P.S. You won't believe that I'm uploading this thread during call.
Help if anyone know about it.
