Despite your very strange iPhone problems, you'll regret the move to Android. You'll see.
I don't know what Ox is talking about. The Android system is perfectly fine and it allows for greater freedom amongst phones than the proprietary IOS.
while both of these statements are likely true, I'll put my $.02 in for a different point of view. my experience is whichever platform you learn on, or start out with, is the OS you will prefer. more times than not, I have seen iPhone users try Androids, and Android users try iPhones, and both typically do not like it. There are a few who switch and prefer it, but in my experience, this is the exception, and not the rule.
Both are great platforms, but i think with the iPhone you are more limited to what you can actually do. you may be able to better do what you can do with them (matter of opinion i guess), but they are more limited than android to me. I don't think either is a bad option though.
my last 3 or 4 have been Motorola devices, and i have been pleased. the only other android experience I've had for a phone was an HTC, and i liked it too.
of the 7 phones that I'm responsible for financially, the only people that i hear complaints from are the iPhone users. they are always talk'n about problems, or what they wish it could do, yet fiercely loyal cause it's their iPhone. in fair disclosure though, both are female.
in 4 months I will have paid off my current phone (Droid Turbo) and plan to obtain the Moto Z Force.
i think Samsung are great phones, but I don't think they are that much greater to learn the proprietary differences. maybe i'll change my mind in the next 4 months
