Since version 1.14, a few users have reported a crash with the system Updater whenever they try to open it. In that case, they won’t get notified of the next OTA system update. To solve this problem users need to:
- go to Settings > Apps > See all apps > 3 dot menu > Show system > Updater > Storage & cache
- Tap on Clear storage and validate
- Go to Settings > Updater
- Tap on the refresh arrow
And voila! 1.15 should appear among the available updates!
