Installation steps
Download from the DAMAC release page
Use Chrome on the Android device and wait until the download completes.
Verify the downloaded file
Compare the filename, size and SHA-256 checksum before opening the APK.
Open the completed download
Use Chrome's Downloads list or Android's Downloads app to open the checked file.
Allow this browser temporarily
If Android asks, open settings and allow installation only for Chrome, then return to the prompt.
Install and review the result
Complete installation, open DAMAC and confirm that Android reports no unexpected conflict.
Remove the temporary permission
Turn off Chrome's Install unknown apps permission after setup.
If Android blocks the installation
Check available storage, download completion, package compatibility and whether another build with a different signing certificate is already installed. See DAMAC Android help for a symptom-by-symptom checklist.
