How to Enable Grayscale Mode on Android Smartphones

I don’t think this actually helps with smartphone addiction, but here’s a quick rundown on how to enable grayscale mode on your Android smartphone. There are actually two ways to go about it.

The Easy Way

Depending on your phone model and Android version, you might be able to enable grayscale mode through your device’s Accessibility settings. Look for a “monochromacy” or “grayscale” option under “Color Correction”. If it’s there, you’re all set.

The Hard Way

Here’s how to enable grayscale mode on Android if the option isn’t available under Accessibility Settings.

  1. Go to Settings.
  2. Go to About Phone.
  3. Find the Build Number.
  4. Keep tapping Build Number until the phone acknowledges you as a developer.
  5. Back out to main Settings screen.
  6. Go to Developer Options.
  7. Find and tap Simulate Color Space.
  8. Select “monochromacy” from list.

That’s all it takes to set your android ssmartphone to grayscale mode. It’s not really that hard, but there are more steps involved. Ideally, Android settings should come with a grayscale switch under Display Settings.

Smartphones vs Personal Computers

I think that expanding the capabilities of mobile phones until they became handheld computers was a mistake. Instead, I think we should have worked on miniaturizing general purpose PCs until we had handheld computers with touch screens that ran VOIP apps on our choice of operating system (Windows, Linux, BSD, or OSX) and could be plugged into a docking station via USB for desktop work.

There’s no technological reason we can’t. And there’s no shortage of blog posts explaining how to use a smartphone as a desktop computer. However, they all suffer from some crippling limitations:

  • You must use a wireless mouse and keyboard.
  • You’re stuck using Android or iOS, both of which are locked down.
  • Unless you can root/jailbreak your device, you’re limited to software available from your device’s app store.
  • There isn’t a unified standard for connectivity to external devices such as monitors, keyboards, mice/trackballs, and external storage.
  • You cannot access external storage.

The Raspberry Pi solves the problems I listed above, but has its own drawbacks. While touchscreens for the Pi are available, they come in sizes that make the Pi unsuitable for use as a smartphone. Nor does the Pi connect to mobile phone networks by default; its wireless connectivity is based on the 802.11 wifi standards.
