How to enable Grayscale mode on any device – No Root

A grayscale mode is an option which is officially available to very limited devices. But it is still there on others. It is quite useful for reading any kind of e-books or articles online as it puts less strain on your eyes and also does some wonders by saving a bit of your phone’s battery. So today, I’m gonna show you how to enable it.




  1. Go to Settings > About Phone and tap on the ‘Build Number‘ seven times in rapid succession. Then a toast message will appear telling, ‘You are now a developer’ (Means now you have access to the developer settings).
  2. Now go to Settings and deep down you’ll see ‘Developer Options‘. Select it and scroll down to the button and find the ‘Hardware Acceleration Rendering‘ option close to the bottom of the section.
  3. At the bottom of the ‘Hardware Acceleration Rendering‘, select ‘Stimulate Colour Space‘ option. Then, choose the ‘Monochmacy‘ option from the popup. Your screen would immediately enter into grayscale mode. Everything on your screen would go black and white.
  4. To revert back to normal, repeat Step 2 and then, simply disable the ‘Stimulate Colour Space‘ option. it would revert your screen back to normal.

It’s not as handy as any other quick setting tile, but still fairly easy to access and some major benefits. So what are your thoughts and experience with the ‘grayscale’ mode? How much of effect it had on the battery. Please share it with us in the comments section below.
