How to make android prefer mobile data when wifi signal is very weak When I leave home or the office there is a ring around it where I simply have no connection at all. This is because the WLAN network from my router at home or the one at the office is detected, but the signal is so weak that no useful data flow can occur.

Is there a way in which I can make android use the mobile data network when the WLAN signal strength is below a certain strength so that there isn't this annoying "dead ring of no connectivity"?

Googling this problem or searching the app store keeps giving me solutions for the exact opposite.

thanks in advance
From Android 5 onwards, there's a setting in the Developer options called Aggressive WiFi to mobile handover.

Enabling this setting makes your phone switch to mobile connection when the WiFi signal is too weak.
