I have Z5 Compact and I can not find the function Аvoid poor connection. I find it very useful - when tthe wifi is bad, to go with my data plan.
Thank you, it seems it is the function I have in mind. Only one observation - it seems it react in case of bad wifi signal, but not in case of bad internet connection. I made a test, I interrupted the Internet connection of my router. So, in case of strong wifi signal without internet, it does not switch to Cellular.
(I could've sworn I replied to this the other day)
Ah, you want to go the other way.
Have you ever used an app called Tasker?
If you're savvy with programming - you could get it to test the Wifi signal against a DNS, and when it returns nothing, you could set the phone to "Mobile data always active"
