I have a Samsung Galaxy S2, unlocked, ROM from Samsung/T-Mobile, and it is working fine. I hate to give it up, but my bank has come up with a new version of its app that allows me to deposit checks by photographing them with the phone Unfortunately, the photo function fails to display the image that I am about to click on, so it is impossible to use. At first the bank said that it should work with the SGS2, and then they said that the SGS2 is "not supported." I really think the problem is in their app and not the SGS2, but there is nothing I can do about that. Hence, I am shopping for a new phone. Here are my requirements, sine qua non: microSD card, preferably 64 GB T-Mobile LTE replaceable battery I tried looking at T-Mobile's website for phone options, but it was hopeless trying to figure out the specs for the various phone options. It would take me hours. I am hoping that there is someone here who knows all the T-Mobile phone options and can give me a short list of what to look at. Bear in mind that I do not need the latest and greatest. Also, I will buy the phone on eBay or Craigslist and pay cash for it. Suggestions?
