On the Oneplus site they are selling 8 and 8T models locked to T-Mobile for $299 (128 GB) and $449 (256 GB). I have a 7T with 128 GB that I can get up to $100 for a trade-in. my camera needs are routine. I am not tied to wireless charging.
What experiences do OnePlus 8 and 8T owners have with their phones?
