Wi-Fi connection

Good morning,

I living in my own house and using two routers, "Stas" and "Stanislav". When my phone is connected to one of the routers and I am getting close to the other one, that has stronger signal, my phone is still connected to the first router that has weaker signal, it's almost not working but still not picking up the signal from the second router with stronger signal. Please correct the problem in your next updates. Phone needs to pick up Wi-Fi signal from available stronger router automatically. Thanks!
