| Jun 5, 2015 at 9:07 | comment | added | Zero | I have tried it, and while the dimming transition was too smooth (fairly distinct steps from dim to bright and the other way around) I did not experience any flicker on dimmed screen in my dark closet - will try my room at night. If you have the option try using 'screen filter' module on xposed framework (requires root). It allows going much dimmer than 'twilight' (almost to the point where screen is too dim to see in day light) and still no flicker. | |

The flicker is not noticeable to the human eye, unless you do a trick. Go to a completely dark room, and take your phone, and pass it left and right across your face as fast as you can You will noticed slight discrete squares. If not, your screen may not be dim enough. To dim more: Download the twilight app. Put it on max dimness. Set your phone to max dimness. Now try. Let me know if that works for you. Tested on Samsung Galaxy S6

| Jun 2, 2015 at 23:18 | comment | added | Jonathan | I know for a fact it is flickering, because if i am in a dark room, and i move the phone quickly, i see discrete areas of light, like rectangles, where the phone was moved through | |
