Hi Odd problem recently experienced on my s5. I'm unable to set a default browser. I get the option to select and save a default browser (stock and chrome) however setting does not save. Both "launch as default" options on browsers under application manager greyed out. Unable to disable stock browser as that option also greyed out in app manager. Pretty savvy with Android and have download many apps to dig out cause to no avail default app manager apps unable to resolve issue.uninstalled all apps which i deemed could be the cause but no joy. Phone otherwise sweet as a nut. Without having to backup reset etc for such a small issue is pointless but any suggestions would help.. Unlocked s5 not rooted.
