Can I activate a Blue Light Filter on BLU Diamond M D210L?
Activating a Blue Light Filter / Night Mode on your BLU Diamond M D210L
If your phone uses a fairly new software, simply unlock your BLU Diamond M D210L and open the Settings menu.
Select the Display option and search for a Blue Light Filter option. They can use one of many names - Night Mode, Night Light, Reading Mode and such. All of these basically do the same, making your phone's colors warmer once you turn it on.
You can either choose an option for this mode to start when the sun sets (it can be named something like Goodnight or Reading Before Sleep mode) or schedule when should it start by yourself.
Once you're done, that's it! Your BLU Diamond M D210L will now change the displayed colors to warmer ones once the Blue Light Filter is applied!
