I am trying to investigate why our Phones are experiencing slow browsing to HTTPS sites.
It happens only the first time after the phone in question has been locked for a couple of minutes or more. So when browsing to a https site after unlocking it, it takes over 1 minute. Then, suddenly everything works until the next time we lock the phone screen and leave it for a while.
We are on my company wifi, and it is only happening there it seems.
I have tried everything when it comes to the router, and it is not an ISP fault.
Tried to use packetcapture app while connecting to a https site after unlocking phone, seems to be port 443 used by the https websites.
If I open for example BBC.COM (which seems to use a non secure port 80) it works fast and normal.
BTW: Traceroute and Pinging shows great results to the https sites, and download speeds are great as well. Happens only on browsers (Both chrome and Stock samsung browsers).
