Re: Galaxy S5
"Mine is regularly updated too; certainly would point to the local phone provider rather than sammy being to blame for the OP's missfortune."
Mine is patch level "June 01 2016". That's quite some time ago. Even that didn't bring the phone fully up to date for June 1, 2016. Prior to that, there was more than 6 months between patches. Not okay.
None of the patches actually seem to solve any of the fundamental issues with the device either. Driver issues, touch screen issues, wakelocks, terrible connectivity...
The S5 is a piece of shit, and so are all the modern "flagship" Samsung phones. Samsung used to be good. Now they peddle neglected crap. Simple as that.
