Does anyone of you also noticed that the phone is vibrating two times shortly after entering pin of the sim after a restart? there is no notification about this and im wondering where this vibration is coming from.

In safe boot nothing vibrates, so it must be an app causing this. is there a possiblity to get a log of the phone which app is causing after boot the vibration? it happened after i have added manualy an apn entry for mobile data. before, i made a factory reset, added wifi and connected to google play and updated all apps. no additional apps were installed only the ones that were preinstalled were updated.

i also noticed that the automatic apn entry retrieval (download internet settings) via settings is not adding any apn.

this is a international german dual sim xz2c with latest april patch. network is o2 by netzclub.

after testing i think that it might be due to whatsapp. after whatsapp instalaltion it happened. need to test it if it happens still without whatsapp.
