Not really a "feature" but a request for more info in the Ting Web Storefront.
With phone listings in the Ting store, It would be helpful to list user available storage (after the manufacturer's software and Sprint software is installed - perhaps even after the most recent updates, if any, had been applied to that "base" software/minimal configuration databases). I.e, what the user would see as available storage if they took the phone out of the box, activated it, and then applied all updates to whatever was already on the phone.
This would be particularly interesting for entry level phones as space is tight (and, since the "move to SD Card" feature is long gone from Android and some apps, such as Google Maps, refuse to use the SD card for offline maps, the SD card is not of any use for some apps anymore).
If this information is not reasonably available (maybe Ting never really opens the box and tests the phone?), at least if a review is done by Ting (when obviously the phone has been activated and used), this information could be included there from the initial unboxing experience.
For example, I'm comparing the Motorola Moto E (Second Gen) and the LG Volt 2 (amazingly inexpensive!). Both have 8GB of internal storage but I have no idea how much Motorola's or LG's version of Android or Motorola or LG app bloat consumes or what Sprint bloat consumes -- i.e., what I have left. With an 8GB phone, 1GB makes a huge difference. PhoneScoop reports that the Motorola has 5 GB available to user and that the LG only has 3.4 GB available to user but I have no idea if these numbers are accurate. The difference could be due to Android 5.0 vs. 5.1 and/or LG bloat vs. Motorola bloat -- and, I'm assuming, neither includes Sprint bloat(?). So, I just have to guess as to if there will be enough internal storage to meet my needs (or if I have to use alternatives to my preferred apps - such as HERE maps instead of Google Maps offline feature). All that really matters to the purchaser is how much storage is available to them :)
