I did when the S7 came out. Mother needed a new phone so I gave her my old 6s (which at that point was my favourite cell phone ever) but it's my mom wanted to give her the best.
Ended up getting an s7 for free during a promotion via my service provider so I went with it. Had tried to go android several times before (moto g, galaxy nexus, one plus one, galaxy s6, nexus 9 with tablet, nexus 6p) But it just never worked out and always ended up defaulting back to iOS for one reason or another.
But I figured hey the phone was free, my mom doesn't like android so she can have my phone and all I need the phone for at the end of the day are texts, calls email and browsing, with some apps like snapchat and WhatsApp I use, and a good phone camera to take pics with.
Ended up falling in love with the phone. What a wonderful piece of tech the S7 was and it fixed almost every criticism I had with the S6, and it has features that I miss anytime I go back to iOS (6s, SE or 7) now.
Funny how at one point I thought going android was the one of the worst decisions I could make but it ended up being one of the best since I now have a complete understanding and respect for the OS (mind you I loved the 6p and one plus phones too...and I did like the S6 just had a few issues w it....but never used the phones long enough to truly commit to giving android a respectable shot)
The lack of quality Samsung or google or really any android manufacturer customer service in Canada Vs apple is my main sticking point against Droid right now. The other sticking point is I have a lot of family over seas who use FaceTime and iMessage but I use my mac laptop or iPad for that now.
But now when I switch to iOS I just miss enough features that the S7 has that I Keep coming back to it.
It's one of the best phones I've ever used.
