Ipad2
my ipad2 screen is totally low brightness and it does not change when tried to increase the brightness
iPhone 4S, iOS 5.1.1
Try the following:
- Perform a soft reset: Hold down both the Home & Power buttons simultaneously until the Apple Logo appears, then release them both. See if this resolves the problem, if not, continue to the next step.
- Perform a "Reset All Settings" reset: Settings > General > Reset > Reset All Settings
This will bring your iPad back to its default state without erasing any of your data.
