iPhone randomly switching to cellular data with Wi-Fi Assist off

Hello, My iPhone keeps switching to cellular data when both Wi-Fi and cellular data enabled even if I have full Wi-Fi bars and Wi-Fi Assist turned off. iPhone should only switch to cellular data when it's already out of Wi-Fi range but it still switches to use cellular data especially when I open my iPhone from idle.
