My Samsung Galaxy S6 just did an update back on May 8th. Afterwards I've noticed that when I tap my phone it can take 30 seconds to a minute (or more) for it to finally connect to my WiFi... That is EXTREMELY frustrating as I have to sit and wait instead of just being able to use my phone and do what I need to, otherwise I would end up wasting a LOT of cell data... Before the update it would connect super quick, maybe within 5 seconds or so....
This also happens when I'm at other locations with wifi (like a store)...
Nothing else changed, just the system update. I tried rebooting the phone again, I tried clearing the cache partition, I tried rebooting my router.
Even if I turn wifi off on my phone, then turn it back on, it is very slow 'scanning for networks' before anything starts to show...
It always seems to be a gamble when Verizon rolls out an update. and when they do break something like this we have to wait a month (or apparently now the S6 is on quarterly updates) before it gets fixed....
