Maybe it's one of > those last minute edits that went wrong. I can imagine that during the time the system powers the ALS down, the actual sensor keeps measuring and writing to their internal buffer. The moment of a drivers read it will get the recent sample with "just" a delay resulting from runtime pm settings. That delay is probably not very noticeable in practice. I think that way nobody noticed it. Thank you, Alexander
