OK GOOGLE on Samsung Galaxy S7 doesn’t work

To make Ok Google detection work on Galaxy S7 (Galaxy series phones) we need to perform a couple of steps.

1. As long as Samsung S voice is enabled, it interferes with Ok Google detection.

So disable S Voice first.

Goto settings -> Apps -> S Voice -> Disable. If needed Force Stop the app.

2. Make sure S voice is no longer the default app for voice commands. Otherwise the phone will start it again instead of Google assistant.

Goto settings -> Apps -> Default apps -> Device assistance app

Make sure that the device assistance app is Google.

3. Make sure “Ok Google” is turned ON.

Tap the google search bar to go to the Google Now app. Tap the big G at the top left corner and then the three bars at the top left corner and choose settings -> Voice -> OK Google detection. Make sure that Ok Google detection is turned on and Trusted voice is turned on too. Train voice model.

4. Restart the phone. This is a crucial step.

Common questions on climate change

1.  Are renewable energy systems even viable or are they just an Utopian dream of impractical scientists? And even if they are viable wouldn’t it cost an arm and a leg to make them viable?

Among the multitude of scientific journal articles, which answers both these questions separately, one article answers both these questions succinctly in a single paper.

In 2011 Jacobson et al. proposed a 100% WWS (wind, water, solar) energy system which can supplant the current fossil fuel industry. They found that production cost of WWS is exactly same as current fossil fuel-derived energy systems and that includes costs of production, storing, and transmission (with transmission losses). Their conclusion is that “ … barriers to a 100% conversion to WWS power worldwide are primarily social and political, not technological or even economic.”

2. Which countries invest the most in renewables?
