Re: @Charlie Clark
There is no way I have the money to take on Samsung in the courts.
But I didn't say that. I think it's terrible the way the companies behave. I don't know the setup in Canada but I'm referring to things like the action currently being led by the Dutch consumer rights authorities to try and enforce timely distribution of security patches. I assume you have something like a consumer advice bureau in Canada. If enough customers get up of their fat, lazy, entitled arses and start complaining then the authorities might take action.
My S5 with CM is fine. Wifi isn't at all patchy if a bit greedy. I don't have a 4G SIM but 3G is fine. I have Samsung phones for about 10 years now and they've all been pretty good.
The idea that having to load a third party ROM to get security updates is somehow acceptable
See above: I do think that the companies should be doing a lot more but in their absence I'd rather do something rather than nothing. Bitching about Samsung, or any other company, on an internet forum certainly isn't going to change anything. And if it makes me an asshat to point this out, then I'm happy to be one.
