The current version of the App on Play Store is outdated by at least 3 versions. The latest version of the App is alpha_1.4.1+, you can directly sideload the .apk by downloading it from here – https://bit.ly/csos_latest_apk . The latest version is very stable and especially fixes the issue of black screen when an App is attempted to launch from CoverScreen OS’s App drawer.

The delay in updates on Play Store is courtesy of COVID, Google Team requires longer than usual time to review each update. Follow the 100+ hour per week development effort on this Telegram group – https://t.me/csos_com and if you would just like to be notified of new versions before it releases on Play Store, you can join this Telegram Channel – https://t.me/csos_updates . All the support for this project is much appreciated!
