I had no issues with 4.11.2
Deployment was smooth, everything worked fine (except whatever bugs I reported).
Yesterday I installed 4.12.3 (and updated to 4.12.4 today) and built .apk today. Build was successful. After plugging my phone into Gear VR all I saw was pitch black screen. I did not change anything in the project settings, didn’t alter my scene either. Simply converted project from 4.11 to 4.12.

Has anyone had same issue ? How did you resolve ?
P.S. I don’t use HDR, same scene worked from 4.9 to 4.11.2, OSIG is where it should be, everything the same as in 4.11 (unless 4.12.4 removes some settings)
