Regular readers want to be aware of the fact that Google is in the process of adding Android applications, including Phone, Contacts, Messages, and so on on, presumably in preparation for the holy grail – a system-wide dark mode. An app of slightly lesser importance is the Google Calculator, but it is receiving the dark-processing nonetheless.
Version 7.6 is currently rolling out to users. At first glance, it appears to have been changed, except for a little pill to make it clear. If you tap the overflow (three-dot) menu, you'll find the new 'Choose theme' option, which allows you to select Light Dark or Set
Light Light Dark Dark Dark Dark black), and the final choice will keep things bright until battery saver mode is triggered. And that's about all there is to it.
It's worth noting – it was not something we were really aware of before – that is, the display ratio of your device is high, you'll get the advanced equation options above the number pad rather than in a slide-out panel. Google Calculator version 7.6 is now rolling out now via the Play Store but you can download it from APK Mirror right now.
