does it work for 5.1.1?

I am sooo pissed off that these devs do not continue to support our devices. I am not one to run out and buy a brand new device when mine would work just fine if they would provide the updates! Shame on them!! They need to get a clue and get out of their little cubbys and come down to the real world of non fiction where we live. Use our devices and see what we are up against. And now days I think they assume everyone knows what they know technically and we should be able to code our devices. It’s kind of like water, we all need it but we don’t care how it get here as long as it’s here, safe, reliable, and we don’t lose our skin when we use it! What was a good idea to make life easier, save paper, trees, etc, has become a nightmare of uncertainty, thieves, hackers, and not everyone uses their device just for entertainment. I work on mine and you know how much it has costed me for their negligence!! Allot of $$$. I should send them a bill!
