Enable Auto Brightness Mode on Xperia S [App]

The Sony Xperia S comes with auto brightness for the screen disabled by default, and does not have any option in the phone settings to enable it. This is contrary to some earlier Xperia phones where auto brightness was always on without the option to disable it and could only be disabled by a hack/root access. Generally, the Xperia S would need root access to enable auto brightness, but there’s a method that doesn’t require you to root your Xperia S in order to enable auto brightness.

Read on to find out how you can enable auto brightness on your Sony Xperia S.
