I am thinking about getting a phone - probably the LG G3 - from an outlet that sells foreign versions with the same spec at a much cheaper price.
I understand that doing this with Samsung phones causes big problems if you then want to use the phone abroad with a local SIM, due to their region-locking.
Does this only apply to Samsung, or do other manufacturers engage in this as well? (i.e. is there any disadvantage to purchasing in this way if it is not a Samsung?)
