Same. Happened last week, and gave me the option to'reset' the launcher... Did that and lost all personalized settings. Back to default look.
Then did it again last night. So did a factory restore.
Since then, it's been overnight, a couple hours using for work this morning, and seems ok... But not been long enough to judge.
I've only had my duo 2 for 6 weeks, but generally I do factory restores on my android devices every 6 months to keep them running well. Hope that's it for 12 months for me. 😁
