Thanks Mark Nord for opening the issue,
I removed all prs-plus settings, uninstalled prs-plus, made hard reset and installed prs-plus again. Then I made new build using latest revision, removed all the games, calculator and calendar. Cleaned all unnecessary from StandbyImage.js and unused lines in lang.ods, unfortunately it didnít work. After removing StandardActions.js it started to work. Only visible glitch is in formatting overly and I canít close it by page tap.
Is the StandardActions.js essential for 950?
