Hello I am impressed with the amount of info on this site. I have a Samsung note 3 and stayed with version 4.3 using Sprint. and my pc is the surface pro 3. I am using pdanet and no problem. 6 months out of the year I am in an area without wifi and I depend on pdanet. I just purchased the Microsoft universal folding keyboard.. I like it...but it will not work with version 4.3. It will only work on 4.4 or higher and I will not keep the keyboard if I lose pdanet. I have not purchased a new phone because of this. I do not know what options I might have. I cannot mirror my phone to my pc ( that would be like having pdanet) Perhaps a windows phone running version 10 might mirror to my pc...if not then when the new surface phone comes out I have a feeling it would since it should be a pocket pc ( however windows is not for this site I guess) I do like the Samsung Note ( I do not mind a different model) The important thing for me is having wifi from pdanet. Thank you for taking the time to read my long winded plea for help.
