GPS Rollover on Android Smartphones Regarding the GPS weeks rollover which took place on April 06th 2019. all the websites are talking about the phenomenon but they are not explaining what are the side effects on end users devices if the week number will be 0000.

How an Android smartphone GPS users could be affected regarding this rollover from 1023 to 0000 weeks ?

Regards
From what I know the rollover is not the only problem, also an additional week counter 13 bits is introduced. A new data format (with larger data) can of course cause problems if unsupported by the GPS receiver firmware.

Also I have read that some GPS devices use the week counter for plausibility checking of the received data. If the week is smaller than the manufacturing week the data have to be invalid so the simple but bad logic. After the roll-over it will simply reject all incoming data as the receiver thinks that the received data is invalid (e.g. because of radiointerference).
