Found myself in the exact same situation (have a WileyFox, updated and ended up with the awful true caller app as the default dialler + found I couldn't use the default google dialler), I've since been using: https://play.google.com/store/apps/details?id=com.contapps.android.dialer&hl=en https://play.google.com/store/apps/details?id=com.contapps.a... but it does have adverts, I'd welcome any other suggestions (aside from re-flash). Only today I was joking about how absurd it is that I was struggling with such a fundamental feature.
