Engineering Samples can have a few missing features, usually not many(very few), but Qualification Samples are always fully functional, otherwise they would not pass qualification testing. QS models tend to be more rare, but if you can find one, grab it! They are usually unlocked and unrestricted.Thank you so much!
Generally, when these ES/QS models are sold. Is anything performance-wise not included compared to the retail production?
