Google is looking to offer a native Terminal app for Android, possibly with Android 16. The Terminal app will allow installation of a Linux VM with full GUI and GPU acceleration along with other sysadmin features including disk resizing, port forwarding, and partition recovery. This is an extension of Google's earlier project of allowing Chrome OS to run on Android using the Android Virtualization Framework.
So that’s why google is killing termux.
How is Google killing termux?
By breaking the play store version often. It was not possible for author to update it for several years. Seems it got better recently, but still, to have a full fledged version of Termux, you need to install it from a different source - f-droid, ideally.
