Redmi Note 15 Pro WiFi Disconnect Issue

I purchased a Redmi Note 15 Pro mobile phone on 10/03/2026, and from the first day I have been experiencing constant Wi-Fi disconnections. While using the phone, the Wi-Fi connection frequently drops on its own and reconnects again, which makes it very difficult to use the internet. This problem does not occur with my other devices connected to the same modem and network, so I am sure the issue is with the phone, not the internet connection. Because of this ongoing problem, I cannot use the device efficiently for its intended purpose. I have not yet contacted Xiaomi/Redmi technical service and I have no technical report, but I experience this Wi-Fi disconnection issue continuously in daily use. Due to this fault that has existed since the first day and prevents proper use of the device, I request that the sale of my Redmi Note 15 Pro be canceled and that a full refund be made.
