A:AnswerI recently purchased and placed this in my LG G4, and it works flawlessly so far. been about 2 weeks. Best decision I have made for that phone so far, would have gotten larger if they existed or were not super spendy.
A:AnswerIt might work with your s5, but there might be a limit to how much additional memory it will work with your phone. Some phone has a limit like it can only support an additional 32gb 64gb, or 128gb.
A:AnswerUnless your S4 is extremely different from my Galaxy S4 on Verizon then can only handle up to 64 gb of space. But to answer your question, If you have any friends in America you can send it to them and get them to send it to you hopefully.
A:AnswerMy wife has the Galaxy S7, not the Edge, & it works fine in her phone. My understanding is that the Edge S7 & the regular S7 are the same phone, just different on the screen.
