Ever since I purchased my S10 mobile, I always wondered why can't apps use full screen rather than black area around camera hole. The settings which doesn't force apps to strech full screen not helpful but with multistar update, now I'm able to force apps to use entire screen.
Last option
Before (when using settings fullscreen option). Notice blackbar at left edge.
After enabling option in mutistar (no blackbar)
It took a long time to implement this or didn't find by me but now its came finally.
P.S. Selected tech talk to upload screenshots, move or let me know if its not right place.
Some screenshots below..
