Ascolta musica gratis, scarica suonerie gratis, ho usato molte app.

i also think it need root access. .

it will not work on newer android devices, due to Google's change in allowing access to screen space overlay rendering. sad.

you can root and flash a kernel with K-Lapse , then use a kernel manager app to create your own custom settings according to either available light or time of day.

also some native roms have night shift which is pretty similar to f.lux, just not much control over it.

There's just no reason why a "clear" screen protector should make any difference to sleep or alertness.

how about an apk file to sideload from apknite store?
