Hi all. So I am considering a switch to Android phones for various reasons. One being the size of the iPhone. The larger sizes are just not for me. But if I'm going to switch over, I'd love for it to fulfill a few other criteria. What's great about Android is that there are so many phones to choose from! Which can be daunting to a newcomer. So here are some criteria I'm looking to fill. * 4" - 4.5" screen (but overall size should be smaller than an iPhone 6. The 5S was near perfect form, it can be bigger than that though) * Works on US T-Mobile LTE or HSPA+ * Have WiFi calling available (necessary on TMO) * Unlocked BONUS: * Dual SIM (Dual SIM is nice but not mandatory) I have been playing around with a Galaxy S4 mini that a friend gave to me to see if I would like Android and I do! But I'd like something newer so I've been thinking about the S5 Mini but the dual SIM version doesn't seem to have US LTE compatible bands, unless I'm reading things incorrectly. Suggestions would be much appreciated. Thank you!
