Got hands on this properly today only, Came to know that apple has not change or upgrade entire thing.
Some upgrades are ofcourse there and they are pretty much better than older 5s
Because it has 2GB Ram and it runs smoothly touch id is updated as well its quicker than before, OS is updated as you may know. Battery is a bit disappoint but for those who are looking for a compact but powerful phone iPhone SE is a great choice.
Some colors are added like Rose Gold that I don’t like but rest assured about performance its a great upgrade.
