I have been doing some more testing of GCS’s with 2 Samsung Galaxy phones that I have - an S4 and an S6 and I have found that Mission Maker for Android works fine on the S4 (Android ver 5.0.1) with both the telemetry radio link and the UVC video. However, Mission Maker crashes on my S6 (Android ver 7.0) and I remembered an issue that was reported last year about Tower needing to be recompiled for the 64-bit S6.
A recompiled version of Tower (ver 4.0) is available here Tower is crashing when using UVC stream @Android 6.0.
I originally couldn’t get the UVC video stream to display because I also needed to go into Settings > User Interface > Widgets preferences and select UVC Video. Now Mission Maker works fine on the S4 and the recompiled Tower works fine on the S6 …
