Advanced Wifi Lock
This app forces wifi to stay connected when the screen is turned off and should work on all devices (phone or tablet).
Extra features included in this (full) version:
- Widget to quickly enable/disable
- Customisable timeout
- Option to ignore timeout when device is charging
- Fully customisable 'Auto Disable Grace Period'
- Stops wifi disconnecting when screen is turned off
- Optional timeout so you don't accidentally leave the phone awake for too long
- Ability to automatically disable wifi if you get disconnected from your wireless Access point (e.g. out of range)
- Confirmed working on the ZTE Blade/Orange San Francisco, Nook Color, Samsung Galaxy Ace (check comments for other devices)
The Timeout starts from when the screen is turned off, and gets reset when the screen is turned back on.
