I'd like to see a smartphone similar to the Samsung Galaxy Avant that's available on T-Mobile. After trying one out, I like how the phone functions,
good reception, & texts come up with a lot of suggested words that make texting faster for me. Currently, that phone is only on T-Mobile & MetroPCS, & if unlocked, it would only work on Verizon for LTE Band 4, since it doesn't have Band 13, nor does it have CDMA on it. The Galaxy S4 & S5 are still too expensive for last year's models (even the S3 is still too expensive for a phone that was released 3 or 4 years ago, & some models only have Band 13, while the earliest versions are 3G only). I hope Verizon comes out with some better prepaid smartphones for 4G LTE.
The selection on this page http://www.verizonwireless.com/prepaid/smartphone-plans/, is about the best I have ever seen. Up until recently there were only 3 phones, if I remember correctly, and none of them were worth very much. It's possible we may see a few more added to the selection at some point, especially with the new pre-paid plans rolling out now New Prepaid Smartphone Plans: More Data, Same Starting Price, but I doubt there will be too many low-mid-range Samsung's, exclusive or not.
