I'm a relatively new Android user. Are there any apps that can open, edit and save .txt files for an Android 2.3 7 tablet? Also, since my tablet is having trouble connecting to wi-fi (as I've found out is common with this model), is there any way I download the app to Windows and import it to my tablet, possibly through a USB flash drive? I have APK Manager and My Pad as my application and file managers. The tablet (two-in-one notebook/tablet) comes with a keyboard. Much thanks.
