We’re yet to see any confirmation in US, but the Moto G 3rd Gen in India (model no. XT1550) is receiving the Stagefright fixer OTA update today, that brings up the build no. to LPI23.72-47.4. The software version of the update is 23.46.4.en.03.
Other additions mentioned in the changelog tips at inclusion of ‘night mode’ in the camera app, and then some other bug fixes and stability improvements.
If your device’s model no. is also XT1550, then it’s eligible for the update. To grab the update now, try ‘check for update’ option in Settings > About device > System updates.
A similar update for other regions, Europe and US included, should be rolling out soon now.
Do let us know how the update is treating your device once you get it.
