Description

Fixes issues 1.1 ("Call screen not appearing") and 1.7 ("No preview for video message") as identified in the Android regression test results found here: https://www.notion.so/oxen/Android-Regression-Test-Point-Release-1-24-04-24-dev-main-e4b937bfbbfe44998cf584993fe5307e

The call-screen notification issue can still occur on some emulators, but does not seem to occur on physical devices or Linux-based x86_64 emulators, as documented in the following ticket for further investigation at a later date: https://optf.atlassian.net/browse/SES-1831

This PR contains only minor changes where the functionality has been tested & accepted and as such will not be code reviewed before merge into dev at this time to expedite the Android point release.
