Night Mode's main goal is to reduce the brightness of your screen lower than you can achieve with the default settings. This application applies an overlay filter that acts as a dimmer to darken the screen and ensure your eyes don't hurt. Use Cases? - Prevent your eyes from hurting when the screen is too bright - Low light (In bed, theatre, cinema,. ) usage for reading, browsing, texting or gaming - Disable hardware or soft buttons backlight - If you have an AMOLED display, you can also save battery. Permissions? - SYSTEM_ALERT_WINDOW: To show the dimmer overlay - INTERNET and ACCESS_NETWORK_STATE: To send anonymous statistics and bug reports (you can disable them completely in the settings) and to show the ad (yeah, just one :-) Send me an Email if you have any problem, questions or suggestions.
