F-Droid needs some time to compile and provide the new version. DAVdroid 126.96.36.199-ose has already been detected, but we don’t have any influence on their build process. You can however compile DAVdroid yourself at any time.
DAVdroid > 188.8.131.52-ose compatibility issue
On Android 4.0.3, the last working version of DAVdroid is 184.108.40.206-ose. I’ve tried 1.6.2-ose and 1.6.3-ose and both make android freeze when trying to sync.
v220.127.116.11 is doing the job anyway, thanks for your work.
See DAVdroid 1.6.3 release notes: Android 4.1 is required now
