Alarm clock went unreliable with FPOOS 9 and still is on 10

In fact, I do.
I just accept that a smartphone is not 100% reliable in what it does. It can’t be according to my subjective perception of nowadays software quality (or lack thereof), and then there’s still objective stuff like bitflips. I can’t find a reference even for current smartphones having ECC memory.

That is correct.
But the probability wouldn’t be too high I guess. But not zero.

You set the limit with a personal assessment of how secure you want to feel with your alarm solution.
Your current trouble should give you a hint in that regard.

I would return it. And I wouldn’t compare a probably hardwired simple alarm clock with a computer device running overly complex layers of software. It’s quite a stretch.

I would say that’s a sound advice, and I wouldn’t buy two identical ones (same brand + same model = could have the same flaws) :wink: .

I wonder which reasoning here is more rooted in visible reality.
Anyway, back to being constructive …

With @OldRoutard’s suggestion it should be possible to find out whether it’s just the stock clock App acting up for you.
