My phone is a Samsung Galaxy S10e with a model number SM-G970F. Can I swap the motherboard for one with a different model number like SM-G970U ?
I believe you should be fine to swap the board. From what I can find the F version supports dual sim so there is a difference in sim card trays between the two models. If you need one, you can order the correct one from companies like mobile sentrix.
