welcome back Tactician (you must update your signature - lol)
There is a possibility it's not the fault of the new update.
Sometimes it's the videos that have the problem.
I have sometimes a problem for example, with Mobile Strike. There is a video which is "heavy" ? for my player.
In some cases, when the screen gets black, you can try to tab (and let your finger there) for some sec, in the reverse arrow of the phone.
Also tab somewhere in the black screen for 1-2 sec.
