You should update to the newest build and see if that helps. It's Locus Pro only that crashes the webview? Sounds like an issue with Locus Pro maybe?
IIRC ABC uses Chrome as the default webview app. Updating Android Webview is not doing anything for you, unless you've switching to it manually in Dev Settings.
I just upgraded to the newest build for BullHead. Now I need to test and experience whether the setup still crashes on me.
It is mainly Locus Pro that crashes. I submitted logcats to these (competent!) guys, and they looked into it: they come to the conclusion it crashes inside of webview and that is beyond them.
I yes, I fully realize I need to tweak the webview setting in dev options. After testing I will report back here. Tnx for now !
