I'm unsure how the data on my phone is fine, yet so many people complain about it? Could it be down to device/operating system?
As Adrian said, there do appear to be some dead points where buses lose GPS contact or data transmission. The whole area around Sedgefield seems to be a blackspot for this and mobile data. When the 22 does its wind around Wheatley Hill, it often loses its place in the NSAs and disappears off the map at the same time - or suddenly loses 4 minutes on the timeline, but still comes past when it was due.
I suspect that some of the problem with very late buses disappearing completely is whatever means of error correction is built into the software. it's gone the other way from the very early days of the app when there would be phantom buses, that it would claim to be tracking, but in reality had probably supplied the estimates for a bus that hadn't even run (god that was a cold wait for nothing on the weekend of the Durham Christmas Festival - we'll not be doing that again!)
