First I thought I had problems with my wifi, but as I tested it with other devices and found this thread it is obvious: the latest software update for the LG G4 from Verizon disables or breaks the push notification daemon for Gmail, Hangouts and WhatsApp, etc.

Once the phone connects to another access point or the Verizon network for internet access, notifications arrive.

Perhaps I am not alone with the following remarks: instead of numerous unwanted and completely useless bloatware packages from Verizon I expect a fully tested software update before its release to the public.

I still believe that LG G4 is a top-notch andorid phone, however its capabilities - including its processor and its battery life - are greatly suppressed by unnecessary and undeletable applications (bloatware). Instead of freeing up its potential the latest update further deepens the problems.
