I've seen tons of reports of PRLs being 15008 and 1. Then back. Then forth. I've seen PRL 1 exactly once. Besides that one time mine has been 15008.
It is my opinion that this actually indicates a problem with the Android Systems' display of the PRL. All you see occasionally is 1 (the 5008 is missing). I think it's just a display error. I mean, who ever heard of a PRL of "one".
