Xiaomi India — Mi11 Hypercharge

Address:

Bangalore Marathahalli

Ever since the phone has been upgraded to MIUI 13 OS, Wifi connection has become unstable. This is affecting the calls as I take lot of calls from my home and Wifi calling is the only option that works due to poor signal from Airtel. My other phone which is a Samsung A50 works perfectly.
Please help with this issue. There is a bug. The connection keeps flickering on and off and one can see that while taking the call.
