Note 10 plus WiFi issue

[Alabama]

I just notice that my note 10 plus had some WiFi issue which is first my Internet speed is 300mbps when I started to download something in playstore or YouTube video after 2-3min the speed will be reduced to 50-60mbps idk why........ After downloading finish the low speed will be maintain for 10min and back to normal speed. If I try again download something the same issue will begin..... 

Already try network reset, factory reset, soft reset, battery management still the same......My router has no problem and I have tested using s10plus and the note 10 plus... The result is only the note 10 plus had the issue on it..... Idk u guys had tested or facing the same problem... Please let me know... And sorry for my bad grammar 😞

Have you reported this issue?

Ya I bring it to service center but they said there is no problem with the hardware so all

Tbh I actually hardly notice this kind of speed. As long as my download and videos never load I assume its always fast😂

Hahaha

Try forget the wifi, turn on airplane mode for 10 minutes. And then reconnect, see if the problem resolved. Are you using any metal or magnetic case?

Been try that too and Im not using any metal or magnetic case...... It's only happens when u download in bulk or more that 40gb at 1 time so it's not a big deal I guess... Now few days it's back to normal. So far so good 😇
