"test" Notification In All My Mi Devices

[Atore]

I suddenly got a notification today, both on my MI3 and MIPad2, just saying that: test.
It seems to come from the MI browser (the notification icon is the purple one for the browser), but I don't even use that for browsing the internet.

Anyone with a similar case?
Should I be worried? Should I do anything about it?

Thanks

I've got the same thing on my mi4c. Is this a result of the recently found backdoor on all xiaomi phones? I'm really concerned about this!
