1. open Astro and navigate to the root of your internal SDcard
2. click "multi" in the toolbar, then click "zip"
3. enter the name as Calibration.ini
4. long press the .zip file you just created, click edit -> rename -> then delete ".zip" from the file name to make it "calibration.ini" instead of "calibration.ini.zip" and click ok.
5. VEGAn users only, repeat this process (or copy and paste the .ini file) in the root of SDcard2
6. exit astro and power down your g-tab
7. turn it back on (DO NOT TOUCH SCREEN WHILE BOOTING)
8. remove the calibration.ini files from both SD cards.
So, with my stock gTablet, I used the file manager and added a "Calibration.ini" file under /sdcard and rebooted and the touch response was immediately better - around the edges and touch sensitivity.
Woo-Hoo!
