as a x iPhone user I moved to windows mobile, live tiles and Cortana was the best and I miss them loadfs, I took the plunge expecting a wild west messy android experience and bought a s7 edge, I still miss live tiles and Cortana is still the only assistant to do proper location reminders. but apps became a issue for me in 2017 and microsfts blatent disregard over the last 3 years for the consumer and the developer led to apps like paypal and ebay to leave. What I can say is my s7 edge running marchmellow and nougat is absolutely not the wild west. battery life is like no other phone I have owned and ive owned a lot of smart phones, smooth running os and apps shocked me too, I didn't expect android to run so well, it just does, both iPhone and windows experience isn't even or ever been on par with the reliability my s7 edge has been(the only issue I have is audio. Android headphones repeat track with triple click and hold buton down for google assistant just doesn't work without a app where itll work in windows and ios wdevices as default. Speaker on s7 edge isn't great either.). apps are great and although we miss the odd iPhone app it really is fantastic. having a real you tube app isn't as good as having no adds no hass metro tube or tubecast but unlike those windows ones my you tube official app always works, it even casts in the same app I use daily unlike windowsmobiel did. google maps is way better than microsoft maps and googles intergration with chrome is magnicisant. I loved here maps on windows it was my fav but microsoft got rid of it leaving only microsoft maps, so now I'm using google maps and here go the android here maps. I wont be going back to microsoft and would leave them on desktop too if I could but I cant, microsoft has screwed me and mony other consumers over to many times. they know it too. the Lumia 930 is still one of my favorite phones ever shame the 950 wasn't even close to its quality build.
Go android if your wanting try something, the android of 2017 is not the same as the unreliable mess of 2008. iut really isn't, theres no live tiles which is sadly missed and google cant do everything Cortana does even 3 years later lol. but id still recommend android s7 edge for all the above.
