How does 4g work on your Nexus 5? My connects to 4g network but SFOS browser does not open pages immediately. It takes ~20 sec to open first page. Then it works good, but if i open other page it takes the same 20 sec then works good while i am on that page. Every new page takes too much time. I noticed that when i switch 4g on i can't ping anything. Network does not work for some time at network connection startup.
