- The Android Earthquake Alert system failed to detect recent tremors in north India, possibly due to its recent launch and gradual rollout to Android 5+ users in the country.
- The system utilizes accelerometers in Android smartphones to function as mini-seismometers, identifying potential earthquakes when multiple phones detect simultaneous shaking.
- Once an earthquake is detected, the system sends advance warnings to nearby Android handsets. The feature was recently made available in local languages in India.
- However, the system has limitations including the inability to detect all earthquakes, and errors in estimating magnitude and shaking intensity.
- Usage of this feature requires Wi-Fi and/or cellular data connectivity, with both Android Earthquake Alerts and location settings enabled.
I used to years ago, in the era of Galaxy S2 and such when battery life was a luxury.
I can’t think of a time in recent years where I’ve seen anyone doing that TBH. I know certain people who turn off the wifi router during bedtime.
Same here. I used to do it when location permissions weren’t as robust as well. I don’t bother anymore.
