Hi there. I have had this A50 for a few weeks and has given me no issues until a couple of days ago when first the screen froze. I got it going again with the power/volume key. Then yesterday I realised I have no mobile network signal at all. 4g option isn't even shown in the list of network modes. I seem to remember doing an update the other day including Samsung Pass so I have removed those updates but no joy. Any ideas?
