Hardware requirements

- Android 4.1 (API level 16). For older Android, try Tucnak 4.15.
- Recommended screen resolution at least 640x480.
- Lower resolution use 640x480 internally and output is scaled to native resolution. Tested 480x360, is usable but not optimal.
- SD card with 'reasonable' capacity
- Recommended internet access for DXC/KST
